We will solve each part of the question and differentiate the functions step by step.
(a) f(x) = 5x² + 3x - 7The function is, f(x) = 5x² + 3x - 7
Differentiating the above function, we get;
f'(x) = (5x² + 3x - 7)/dx
f'(x) = 10x + 3
Therefore, the rate of change of function f(x) = 5x² + 3x - 7 is 10x + 3.
Now, let us solve the second part of the question.
(b)[tex]\( g(x)=\frac{-5 x+7}{2 x-3} \)[/tex]The function is,[tex]\( g(x)=\frac{-5 x+7}{2 x-3} \)[/tex]
Differentiating the above function using the quotient rule, we get;

The missing measures of the pentagon are a = 18.4, c = 61.2, d = 75, and x = 22.08.
What are the missing measures of the pentagon?
Let's label the sides of the first pentagon as a, 20, c, 30, and x, and the sides of the second pentagon as 46, 50, d, 102, and 24.
Since both pentagons have the same shape, we know that the corresponding sides are proportional. This means we can set up the following equations:
a/46 = 20/50 = c/d = 30/102 = x/24
Solving for the missing variables:
a = 46(20)/50 = 18.4
c = 30(102)/50 = 61.2
d = 50(30)/20 = 75
x = 24(46)/50 = 22.08
Therefore, the missing measures are a = 18.4, c = 61.2, d = 75, and x = 22.08.

What precisely is a percentage?A number or measure that is represented as a proportion of 100 is known as a "a%" in statistics. Additionally, the terms "pct," "pct," and "pc" are not commonly used. However, it is commonly denoted by the symbol "%". There are no dimensions; the percentage total is flat. Since a percentage's numerator is almost always 100, percentages are actually integers. To indicate that a number is a percentage, either the percentage symbol (%).
Here,
a. The formula: can be used to calculate the weekly payment.
=> P = (Ar(1+r)ⁿ) / ((1+r)^n - 1)
A = 9900, r = 0.06/12, and n = 48 in this instance (since there are 4 years or 48 months in total).
Substituting these numbers into the formula, we get:
=> P = (99000.005(1+0.005)⁴⁸) / ((1+0.005)⁴⁸ - 1) ≈ $227.88
Therefore, the monthly payment is roughly $227.88.
=> Overall = P*n = $227.88 * 48 = $10,942.24
We arrive at $10,942 by rounding this sum to the closest dollar.
c. The total interest paid over the course of the loan's four-year term is equivalent to the total amount repaid less the loan balance:
Total interest equals the total sum less A, or $10,942 minus $9,900, or $1,042.
Rounding this amount to the closest dollar, we get $1,042.

Given: ABCD pyramid All edges congruent AB = 4. 5 Find: V
The volume of the pyramid is found to be approximately 18.046 cubic units.
To find the volume (V) of the pyramid, we need to use the formula for the volume of a pyramid, which is V = (1/3) × Base Area × Height.
In this case, the base is a square, so we can find the area of the base by squaring one of the sides: Base Area = AB² = 4.5² = 20.25.
To find the height of the pyramid, we need to use the Pythagorean theorem to find the slant height, and then use that to find the height. Let h be the height of the pyramid and s be the slant height. We have:
s² = AB² + (1/2) DC² (Pythagorean theorem for triangle ABC)
s² = 4.5² + (1/2) DC²
Since all edges of the pyramid are congruent, we have DC = AB = 4.5. Substituting this into the equation above, we get:
s² = 4.5² + (1/2) × 4.5²
s² = 30.375
s ≈ 5.509
To find the height h, we can use the Pythagorean theorem again for triangle ABD:
h² = AB² - (1/4) s²
h² = 4.5² - (1/4) × 30.375
h² ≈ 7.875
h ≈ 2.807
Now that we have found the base area and the height, we can use the formula for the volume of a pyramid to find V:
V = (1/3) × Base Area × Height
V = (1/3) × 20.25 × 2.807
V ≈ 18.046
Therefore, the volume of the pyramid is approximately 18.046 cubic units.

Question 7 Find the area of the region that is inside the rectangle and outside the circles (blue region ). The circles have a diameter of 3cm
The area of the blue region is 28.93 cm²
How to find the area of the blue region?To find the area of the blue region, we need to subtract the area of the four circle from the area of the rectangle.
Since the diameter of the circle is 3cm. The radius (r) = 3/2 = 1.5 cm.
Length of the rectangle (L) = 4 * diameter of circle (we have 4 circles)
Length of the rectangle = 4 * 3 = 12 cm
Width of the rectangle (W) = diameter of circle = 3 cm
Area of rectangle = L * W
Area of rectangle = 12 * 3 = 36 cm²

Do not round any intermediate computations. Round your answer to the nearest tenth..
Note that the figure below is not drawn to scale.
Answer: Approximately 2 * AC = 737.2 meters. Rounded to the nearest tenth, the answer is 737.2 meters.

where A and B are the entrances of the tunnel, C is the point in the middle of the tunnel that we want to find, and θ, x, and y are the angles and distances given in the problem. We want to find the length of AC.
Using trigonometry, we can find the distances BC and AB: tan(57°) = x / y => x = y * tan(57°)
tan(14°) = x / (y + 212) => x = (y + 212) * tan(14°)
Setting these two expressions for x equal, we get: y * tan(57°) = (y + 212) * tan(14°)
Solving for y, we get: y = 212 / (tan(57°) / tan(14°) - 1) ≈ 286.5 meters
Now we can use the law of sines to find the length of AC: sin(θ) / AC = sin(14°) / BC = sin(57°) / AB
Solving for AC, we get: AC = AB * sin(θ) / sin(57°) ≈ 368.6 meters
Therefore, the length of the entire tunnel is approximately 2 * AC = 737.2 meters. Rounded to the nearest tenth, the answer is 737.2 meters.

Conditional probability question
The conditional probabilities are are (a) P(A/B) = 0.69 b) P(A/B) = 31/100
How to determine the conditional probabilities?You should recall that Probability is the chance that a given event will occur; the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes;
The conditional probability P(A|B) is calculated using:
P(A/B)
P(A/B) = P( A and B) / P(B)
P(A/B) = (18/26 * 8/26)/ 8/26
P(A/B) = (0.69 * 0.31)/ 0.31
P(A/B) = 0.69
P(A/B) = 69/100
b) Using the same formula
P(B/A) = P( B and A) / P(A)
P(A/B) = (8/26 * 18/26) / 18/26
P(A/B) = (0.31 * 0.69)/0.69
P(A/B) = 0.31

A box contains three blue bulbs, four green bulbs and five red bulbs. Four bulbs were taken out of the box at random and without replacement. What is the probability that a. All the four bulbs are of the same colour
The probability of selecting all four bulbs of the same color is approximately 0.0061.
To calculate the probability that all four bulbs are of the same color, we need to consider the following cases,
1) The probability of selecting the first blue bulb is 3/12 (since there are 3 blue bulbs out of 12 total bulbs). After one blue bulb has been selected, there are 2 blue bulbs left out of 11 total bulbs, so the probability of selecting a second blue bulb is 2/11. Similarly, the probability of selecting the third blue bulb is 1/10, and the probability of selecting the fourth blue bulb is 0/9 (since there are no more blue bulbs left). Therefore, the probability of selecting all four blue bulbs is:
(3/12) × (2/11) × (1/10) × (0/9) = 0
2) Using the same logic as in Case 1, the probability of selecting all four green bulbs is:
(4/12) × (3/11) × (2/10) × (1/9) = 1/495
3) The probability of selecting all four red bulbs is:
(5/12) × (4/11) × (3/10) × (2/9) = 2/495
Therefore, the total probability of selecting all four bulbs of the same color is the sum of the probabilities from Cases 2 and 3
1/495 + 2/495 = 3/495
Simplifying this fraction, we get:
3/495 = 1/165

The graph of the parent quadratic
function f(x) = x2 and that of a second function
of the form g(x) = ax2 are shown. What
conclusion can you make about the value of a in the equation of the second function?
The correct answer is D. The value of a in the equation of the second function is greater than 1.
Describe Quadratic Function?A quadratic function is a type of function in algebra that can be written in the form f(x) = ax² + bx + c, where a, b, and c are constants (coefficients) and x is the independent variable. The graph of a quadratic function is a parabola, which is a U-shaped curve.
The coefficient a determines whether the parabola opens upwards (if a > 0) or downwards (if a < 0). The point where the parabola changes direction is called the vertex, which is located at the point (-b/2a, f(-b/2a)).
The coefficient b determines the horizontal position of the vertex, and c determines the vertical position of the vertex.
We know that the parent quadratic function f(x) = x² is a U-shaped curve with its vertex at the origin (0,0).
If the graph of a second function g(x) = ax² intersects the graph of f(x) at exactly one point, then this point must be the vertex of g(x), since the vertex of f(x) is already fixed at the origin.
In order for g(x) to intersect f(x) at exactly one point, the vertex of g(x) must lie on the x-axis (since it cannot be above the x-axis, or else there would be two points of intersection). Therefore, the y-coordinate of the vertex of g(x) is 0.
The vertex of a quadratic function of the form ax² + bx + c has x-coordinate -b/2a and y-coordinate c - b²/4a. Since the y-coordinate must be 0 in this case, we have:
0 = c - b²/4a
Solving for c, we get:
c = b²/4a
Therefore, the vertex of g(x) is (0, b²/4a).
We can see from the graph that the vertex of g(x) is to the right of the origin, so its x-coordinate is positive. This means that the coefficient a must be positive, since otherwise the parabola would open downwards and the vertex would be below the x-axis.
We also know that the vertex of g(x) is above the x-axis, so its y-coordinate (which is b²/4a) must be positive. This means that b^2 and a have the same sign.
Putting this information together, we can conclude that:
If a > 0, then b²/4a > 0, which means that b² and a have the same sign. This means that the parabola opens upwards, and the vertex is above the x-axis. From the graph, we can see that this is the case, so we can eliminate options B and C.
If a < 1, then the parabola is narrower than the parent function f(x) = x², and the vertex is closer to the y-axis. This is not the case from the graph, so we can eliminate option A.
Therefore, the correct answer is D. The value of a in the equation of the second function is greater than 1.

A toy company is building dollhouse furniture. A rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters. What is the perimeter of the door of a scale drawing that uses a scale factor of 3. 5?
If a rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters, the perimeter of the door in the scale drawing is 70 centimeters.
To find the perimeter of the door in the scale drawing, we first need to determine the dimensions of the door in the scale drawing. To do this, we need to multiply the actual dimensions of the door by the scale factor of 3.5.
The height of the door in the scale drawing would be 7 cm x 3.5 = 24.5 cm, and the width would be 3 cm x 3.5 = 10.5 cm.
The perimeter of the door in the scale drawing can be calculated by adding up the lengths of all four sides. The two vertical sides have a length of 24.5 cm, and the two horizontal sides have a length of 10.5 cm. Therefore, the perimeter of the door in the scale drawing is:
P = 2(24.5 cm) + 2(10.5 cm) = 49 cm + 21 cm = 70 cm
Note that the scale drawing is a proportional representation of the actual door, where all corresponding dimensions are multiplied by the same factor of 3.5.

A cylindrical candle has a mass of 200 grams. The candle has a diameter of 3 inches
and a height of 4 inches. What is the density of the candle? Round to the nearest
hundredth
Rounding to the nearest hundredth, the density of the candle is 22.46 grams per cubic inch.
The density of the candle can be found by dividing the mass by the volume of the candle.
The volume of a cylindrical candle can be found using the formula V = πr^2h,
where V is the volume, r is the radius, and h is the height.
First, we need to find the radius of the candle.
The diameter is 3 inches, so the radius is 1.5 inches.
Next, we can plug in the values for r and h into the formula for the volume of a cylinder:
V = π(1.5)^2(4) = 9π

Determine the total number of kilograms from 15 boxes if 1 sachet is 4g
Answer:
50
Step-by-step explanation:
To determine the total number of kilograms from 15 boxes, we need to know the weight of one box. Let's assume that one box contains 50 sachets (this is just an assumption, the actual number may vary). Then the weight of one sachet is 4 grams or 0.004 kilograms.
the weight of one box is:
50 sachets x 0.004 kg/sachet = 0.2 kg
the total weight of 15 boxes is:
15 boxes x 0.2 kg/box = 3 kg
the total weight of 15 boxes is 3 kilograms.
to determine whether the 15 boxes will be enough to last for a year, we need to know how many sachets a person uses in a day. Let's assume that a person uses one sachet per day.
then the total number of sachets used in a year is:
1 sachet/day x 365 days = 365 sachets
the total number of sachets in 15 boxes is:
15 boxes x 50 sachets/box = 750 sachets
since 750 sachets is greater than 365 sachets, 15 boxes will be enough to last for a year.
to determine the number of sachets that will make one box, we need to know the weight of one box and the weight of one sachet. Let's assume that one box weighs 0.2 kg and one sachet weighs 4 grams or 0.004 kg.
then the number of sachets in one box is:
number of sachets = weight of box / weight of one sachet
number of sachets = 0.2 kg / 0.004 kg
number of sachets = 50 sachets
therefore, one box contains 50 sachets.

Jon's parents invested $300 for his college tuition in a savings account when he
was born. The account pays 5% simple interest every year. How much would be
in the account after 18 years if no other money were invested? (1 = Prt)
Jon's parents invested $300 for his college tuition in a savings account when he was born. The account pays 5% simple interest every year. Consequently, if no additional money was invested, the account would be worth $570 after 18 years.
To answer the problem, we must employ the basic interest formula:
Principle x Interest Rate x Time = Simple Interest
where:
Principal = the initial amount invested
Interest Rate = the yearly interest rate expressed in decimal form.
Time = the amount of years the money has been invested for.
The principal in this scenario is $300, the interest rate is 5% (0.05 as a decimal), and the term is 18 years. Thus we may enter the following values into the formula:
Simple Interest = $300 x 0.05 x 18 = $270
As a result, after 18 years, the total money in the account would be:
Total amount = Principal + Simple Interest
=$300 + $270 = $570

Determine the voltage dropped across
The answer of the given question based on the Voltage drop the answer is , the voltage dropped across R3 is 277.11 V.
What is Ohm's law?Ohm's law is fundamental principle in electrical engineering and physics that describes relationship between voltage, current, and resistance in electrical circuit. It states that current through conductor between two points is directly proportional to voltage across two points, and inversely proportional to resistance between them.
To determine the voltage dropped across R3, we need to use Ohm's law and Kirchhoff's circuit laws. First, we can calculate the total resistance in the circuit:
Rtotal = R1 + R2 || R3
R2 || R3 = (R2 * R3) / (R2 + R3) (parallel resistance formula)
Rtotal = R1 + (R2 || R3)
Rtotal = 152 + ((18 * 362) / (18 + 362))
Rtotal = 149.89 Ω (rounded to 2 decimal places)
Next, we can use Ohm's law to calculate the current flowing through the circuit:
I = ET / Rtotal
I = 120 / 149.89
I = 0.8004 A (rounded to 4 decimal places)
Finally, we can use Kirchhoff's voltage law to determine the voltage dropped across R3:
ET = IR1 + IR2 || IR3 + IR3
ET = I(R1 + R2 || R3) + IR3
ET - I(R1 + R2 || R3) = IR3
R3 = (ET - I(R1 + R2 || R3)) / I
R3 = (120 - (0.8004 * (152 + ((18 * 362) / (18 + 362))))) / 0.8004
R3 = 277.11 V (rounded to 2 decimal places)
Therefore, the voltage dropped across R3 is 277.11 V.

It should be noted that the value on the blank on the equation will be -2.
How to solve the equationThe equation given is:
2(4x+1) + 8 = 4(2x+1) + 8 - x
Simplifying the left-hand side:
8x + 2 + 8 = 8x + 4 + 8 - x
Simplifying the right-hand side:
8x + 4 + 8 - _ = 8x + 12 - x
Combining like terms on both sides:
8x + 10 = 8x + 12 - x
Subtracting 8x from both sides:
10 = 12 - x
x = 10 - 12
x = -2
The value will be -2 to make the equations equal.
