equivalent expression in factored form. Do not put spaces in your answers.

1. X2 + 3x+

= (x+

2. X2 + 0. 6x+

= (x+

Answers

Answer 1

a) We need to add 2.25 to the expression to make it a perfect square and equivalent expression is (x + 1.5)^2.

b) We need to add 0.09 to the expression to make it a perfect square and equivalent expression is (x + 0.3)^2.

a) To make the expression X^2 + 3x + ___ a perfect square, we need to add a number that is equal to half of the coefficient of x, squared. In this case, half of 3 is 1.5, and 1.5 squared is 2.25.

X^2 + 3x + 2.25 = (x + 1.5)^2

The equivalent expression in factored form is (x + 1.5)^2, which represents a perfect square trinomial.

b) Similarly, to make the expression X^2 + 0.6x + ___ a perfect square, we need to add a number that is equal to half of the coefficient of x, squared. In this case, half of 0.6 is 0.3, and 0.3 squared is 0.09. Therefore, we need to add 0.09 to the expression to make it a perfect square:

X^2 + 0.6x + 0.09 = (x + 0.3)^2

The equivalent expression in factored form is (x + 0.3)^2, which represents a perfect square trinomial.

From the given question, the value of the height of the cone is given by 57.3 centimeters to the nearest 1 decimal place: Option B

How to determine the volume of a cone?

We should note that a cone is a three-dimensional geometric figure with a flat and curved surface pointed towards the top.  It is formed by using a set of line segments or the lines which connects a common point, called the apex or vertex, to all the points of a circular base(which does not contain the apex)

The volume of the cone is given by the formula

Volume = 1/3πr²h

Where Volume = 1500 centimeters cube, radius = 5 cm, π = 22/7

1500 = 1/3*22/7*5*5*h

1500 = (22*5*5*h)/3*7

Simplifying the expression further we have

1500 = 550h/21

1500(21) = 550h

31500 = 550h

Making h the subject of the relation we have

h = 31500/550

h= 57.272727...

h= 57.3 to one decimal place

Therefore the height of the cone is 57.3 cm

Identify each as function even, odd, or neither. Explain or
show your reasoning.
1. the function k shown here:
A
-2
2. the function f defined by f(x) = 3* + 3-x

Answers

The function f(x) = 3x + 3 - x is neither even nor odd.

The y-axis of the function k's graph is symmetric. This is apparent because, if we reflect any point on the graph across the y-axis, we will obtain a second point on the graph. For purposes of formal definition, the function k is even since k(-x) = k(x) for every x within the range of k.

If the function f(x) = 3x + 3 - x fits the requirements for even or odd functions, we may determine whether it is even, odd, or neither.

Being symmetric around the y-axis means that an even function has f(-x) = f(x) for every x falling inside its domain.

An odd function is symmetric around the origin, which means that for any x falling within the domain of f, f(-x) = -f(x).

We evaluate f(-x) and f(x) to see if they are equivalent in order to determine whether f(x) is even:

f(x) = 3x + 3 - x = 2x + 3 while f(-x) = 3x + 3 - x = -2x + 3

The function f(x) is not even since f(-x) is not equal to f(x).

We assess f(-x) and -f(x) and see if they are equivalent to determine whether f(x) is odd:

F(x) = -3(x) + 3(x) - (x) = -2x + 3 F(x) = -(3x + 3(x) - x) = -2x - 3

The function f(x) is not weird since f(-x) does not equate to -f(x).

The function f(x) = 3x + 3 - x is therefore neither even nor odd.

In a video store, a DVD that sells for $15 is marked 10% off. The amount of discount is $1.50.

If the DVD is marked 10% off, it means the price of the DVD has been reduced by 10% of its original price.

To calculate the amount of the discount, we need to find 10% of the original price. We can do this by multiplying the original price by 10% written as a decimal:

What are the transformations of the function?

Answers

1. Vertical Shift: f(x) + 1 = 2(1/3)ˣ + 2, 2. Horizontal shift: f(x - 2) = 2(1/3)ˣ⁻² + 1, 3. Vertical stretch/compression: 3f(x) = 6(1/3)ˣ + 3, 4. Horizontal stretch/compression: f(2x) = 2(1/3)²ˣ + 1.

Describe Translation?

In two-dimensional geometry, a translation can be described as moving a point or a shape horizontally, vertically, or diagonally. To translate a shape, we can move each of its points by the same vector. For example, to translate a square 3 units to the right and 2 units up, we can move each of its four vertices 3 units to the right and 2 units up.

In three-dimensional geometry, a translation can be described as moving an object in the x, y, or z direction. To translate an object, we can move each of its points by the same vector. For example, to translate a cube 2 units in the x-direction, 3 units in the y-direction, and 4 units in the z-direction, we can move each of its eight vertices by the vector (2, 3, 4).

The function f(x) = 2(1/3)ˣ + 1 can be transformed using different techniques, such as shifting, stretching, or reflecting. Here are some possible transformations:

Vertical shift: Adding a constant to the function shifts the entire graph vertically. For example, adding 1 to f(x) shifts the graph up by 1 unit. The new function is:

f(x) + 1 = 2(1/3)ˣ + 2

Horizontal shift: Adding or subtracting a constant to the input variable x shifts the graph horizontally. For example, replacing x with x - 2 shifts the graph to the right by 2 units. The new function is:

f(x - 2) = 2(1/3)ˣ⁻² + 1

Vertical stretch/compression: Multiplying the function by a constant stretches or compresses the graph vertically. For example, multiplying f(x) by 3 stretches the graph vertically by a factor of 3. The new function is:

3f(x) = 6(1/3)ˣ + 3

Horizontal stretch/compression: Multiplying or dividing the input variable x by a constant stretches or compresses the graph horizontally. For example, replacing x with 2x stretches the graph horizontally by a factor of 1/2. The new function is:

f(2x) = 2(1/3)²ˣ + 1

These are some of the possible transformations of the function f(x) = 2(1/3)^x + 1. By applying one or more of these transformations, we can obtain a new function that represents a shifted, stretched, or reflected version of the original function.

How to calculate Simple interest?

1. Formula of simple interest is,

SI = P*R*T/100 or

Simply write SI = P*R*T

Where,

P = Principal

R = Rate of interest

T = Time period

SI = 20000*18*8/100 or

SI = 200000*0.18*8

SI = 288000

2. Interest = Principal*Interest

             rate*time

Principal = 2000

Interest rate = 10%

Time = January 30, 2001 to September 2001

Interest = 135

(2000*10%*243/360)

Assume 360 days in a year in days counting include the day counting start from and exclude the day counting ends on.

3. Total Interest 3 Years = 300*12%*3 = 108

Total Amount Repaid = 300 + 108 = $408

Total amount to be paid = 300+(300*12%*3)

=$408

4. Given , we need to find the present worth of $20,000 at 12% interest rate per year which is due at the end of 9 months.

Therefore, FV i.e , future value = $20,000

i = rate of interest per year = 12% = 0.12

t or Time =9 months = 9/12 year ( in terms of years)

We know , FV = PV + PV * r * t

=> 20000 = P + P * (0.12) * (9/12)

PV or present value = 18348.62 = $18348.62

5. FV = Principal (1 + rate of interest per period * number of interest period)

Equation-1:

650,000 = Principal (1 + rate of interest per period * 90 days / 360 days)

650,000 = Principal (1 + 0.25 rate of interest per period)

Principal = 650,000 / (1 + 0.25 rate of interest per period)

Equation-2:

600,000 = Principal (1 + rate of interest per period * 30 days / 360 days)

600,000 = Principal (1 + 0.08 rate of interest per period)

Principal = 600,000 / (1 + 0.08 rate of interest per period)

Equating the equations we get:

650,000 / (1 + 0.25r) = 600,000 / (1 + 0.08r)

650,000 (1 + 0.08r) = 600,000 (1 + 0.25r)

650,000 + 52,000r = 600,000 + 150,000r

50,000 = 98,000r

r = 51%

7. Annual return from 18% = 3 * (Annual return from 16%)

Let Investment made in 18% = K

Return from 16% = P620 is less than triple the yearly income from 18%, at P620.

(20,000 - K) * 16% = [3 * (K* 18%)] - 620

3,200 - 0.16K = 0.54 K - 620

2,580 = 0.70 K

K = $3,685.714

So, Amount invested in 18% is $3,685.714

9. EMR = effective monthly rate

EMR = EAR/12

12*EMR = EAR

EAR = 12*EMR

The EMR is given to be 1.2% = 0.012, so the EAR is,

EAR = 12*EMR

EAR = 12*(0.012)

EAR = 0.144

EAR = 14.4%

A recipe for vegetable fritata calls for 10 chard leaves for evry 6 eggs. Eggs are available either by the dozen for $3. 20 or by the half-dozen for $1. 70. Marissa wants to use 25 chard leaves to make a fritata. What is the minimum she should spend on eggs to use all of her chard leaves while keeping the recipe in the correct proportion

Answers

The minimum Marissa should spend on eggs to use all of her chard leaves while keeping the recipe in the correct proportion is $3.40.

To use 10 chard leaves, the recipe calls for 6 eggs. Let's find out how many eggs we need to use 25 chard leaves in the same proportion:

10 chard leaves / 6 eggs = 25 chard leaves / x eggs

where x is the number of eggs needed.

Cross-multiplying, we get:

10 chard leaves * x eggs = 6 eggs * 25 chard leaves

Simplifying, we get:

x = (6 eggs * 25 chard leaves) / 10 chard leaves

x = 15 eggs

So, Marissa needs 15 eggs to use 25 chard leaves in the recipe.

Now, let's find out the cheapest way to buy 15 eggs. She can buy either a dozen eggs for $3.20 or a half-dozen eggs for $1.70. Since a dozen contains 12 eggs and a half-dozen contains 6 eggs, she can either buy:

1 dozen + 3 individual eggs = 15 eggs for $3.20 + $0.24 = $3.44

2 half-dozens = 12 eggs for $3.40

Therefore, the minimum Marissa should spend on eggs to use all of her chard leaves while keeping the recipe in the correct proportion is $3.40.

Perpendicular: y = [tex]\frac{-4}{3 }[/tex] x + 7 [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

20)

y = mx + b

y = __x + ___  We need to find the slope that the y-intercept. We are given the slope 3/4.  We will you the x and y values from the point (2,5) to find the y intercept. Use 5 for y and 2 for x

y = mx + b

5 = 2(3/4) + b

5 = 3/2 + b  Subtract 3/2 from both sides

5 - 3/2 = 3/2 -3/2 +b

[tex]\frac{10}{2}[/tex] - [tex]\frac{3}{2}[/tex] = b

[tex]\frac{7}{2}[/tex] or 3 [tex]\frac{1}{2}[/tex]

y = 3/4x + 3 1/2

21)

Parallel slopes are equal so the slope will be 3/4.  Now we will use the x and y values from the point (5,1) to find the y-intercept.  We will use 1for y and 5 for x

y = mx + b

1 = 5(3/4) +b

1 = 15/4 + b  Subtract 15/4 from both sides.

[tex]\frac{4}{4}[/tex] - [tex]\frac{15}{4}[/tex] = [tex]\frac{15}{4}[/tex] - [tex]\frac{15}{4}[/tex] + b

[tex]\frac{-11}{4}[/tex] or - 2 [tex]\frac{3}{4}[/tex]

y = 3/4 x - 2 3/4

Perpendicular slopes or the opposite reciprocals.  So the slope of the reciprocal equations would be [tex]\frac{-4}{3}[/tex]. We would still use the x and y values from the point (5,1)

1 = -4/3(5) + b

1 = [tex]\frac{-20}{3}[/tex] + b  Add 20/3 to both sides

[tex]\frac{3}{3}[/tex] + [tex]\frac{20}{3}[/tex] = [tex]\frac{-20}{3}[/tex] + [tex]\frac{20}3}[/tex] + b

[tex]\frac{23}{3}[/tex] or 7 2/3

y = [tex]\frac{-4}{3 }[/tex] x + 7 [tex]\frac{2}{3}[/tex]

How do you know when to use cos, tan, or sin when trying to find a segment of a trignagle. Example:
I had to use cos for this and had to find segment AB and AC. i just need a better understanding.

Answers

Answer:


To find AC, you use the tangent ratio, which is opposite over adjacent.

So, tan 27° = 12/AC.

AC = 23.551


To find AB, use the sine function, or opposite over hypotenuse.

So, sin 27° = 12/AB

AB = 26.432

You deposit $2000 into a savings account advertising 7% annual interest rate compounded bi-annually. To nearest dollar, what is your end-of-year balance?

Answers

My end of the year balance is $2,142.45.

What is my end of the year balance?

If the amount that is deposited is compounded bi-annually, it means that both the amount deposited and the interest earned, increases in value twice in a year. This is because bi-annually means twice in a year. An amount that is compounded grows at an exponential rate at each compounding date.

The formula for calculating future value:

FV = P (1 + r)^nm

Where:

FV = Future value P = Present value R = interest rate = 7%/2 = 3.5%m = number of compoundingN = number of years

Hayden wrote the equation 470 divided by h=3,008, where h is the number of hours it took a plane flying at a constant speed of 470 miles per hour to travel 3,008 miles. Solve for h.

Answers

Therefore , the solution of the given problem of equation comes out to be it took the aircraft roughly 0.156 hours, or 9.36 minutes, to fly 3,008 miles at a constant speed of 470 miles per hour.

Define equation.

Variable words are commonly used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic numbers. In this case, normalization produces b + 7, in contrast to another algorithm, which can evaluate data from y + 7, divides 12 through two components, and produces y + 7.

Here,

The formula Hayden created is:

=> 470/h = 3008

We must separate h on one side of the equation in order to solve for it. By increasing both parts of the equation by h, we can achieve this:

=> 470 = 3008h

Then, to get h on its own, split the two sides of the equation by 3008:

=> h = 470/3008

By dividing the numerator and denominator by their 2 largest common factor, we can simplify this fraction:

=> h = 235/1504

Therefore, it took the aircraft roughly 0.156 hours, or 9.36 minutes, to fly 3,008 miles at a constant speed of 470 miles per hour.
