Write a function of the form y= A sin (Bx-C)+D that has period 8, phase shift -2, and the range -12 ≤ y ≤-4.

Answers

Answer 1

The general form of the function is:

y = A sin(Bx - C) + D

To determine the specific values of A, B, C, and D that satisfy the given conditions, we can use the following steps:

Period: The period of a sinusoidal function is given by 2π/B, where B is the coefficient of x in the argument of the sine function. In this case, the period is 8, so we have:

2π/B = 8

Solving for B, we get:

B = π/4

Phase shift: The phase shift of a sinusoidal function is given by C/B, where C is the constant inside the argument of the sine function. In this case, the phase shift is -2, so we have:

C/B = -2

Substituting B from step 1, we get:

C/(π/4) = -2

Solving for C, we get:

C = -π/2

Amplitude and vertical shift: The range of the function is given as -12 ≤ y ≤ -4. The amplitude of a sinusoidal function is half the distance between its maximum and minimum values. In this case, the amplitude is:

(amplitude) = (maximum - minimum)/2 = (-4 - (-12))/2 = 4

The vertical shift of the function is given by the constant term D. Since the minimum value of the function is -12, we have:

D + (amplitude) = -12

Substituting the value of the amplitude from above, we get:

D + 4 = -12

Solving for D, we get:

D = -16

Therefore, the function of the form y = A sin(Bx - C) + D that has period 8, phase shift -2, and the range -12 ≤ y ≤ -4 is:

y = 4 sin(π/4 x + π/2) - 16

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $5500 to rent trucks plus an additional
fee of $200.25 for each ton of sugar.


The second company charges $4995 to rent trucks plus an additional fee of $225.50 for each ton of sugar.
For what amount of sugar do the two companies charge
the same?


What is the cost when the two companies charge the
same?
$

Answers

Let’s solve this problem by setting the cost of the two companies equal to each other and solving for the amount of sugar. Let x be the amount of sugar in tons.

The cost for the first company is 5500 + 200.25x and the cost for the second company is 4995 + 225.50x.

Setting these two expressions equal to each other, we get:

5500 + 200.25x = 4995 + 225.50x

Solving for x, we get:

25.25x = 505

x = 20

So, the two companies charge the same when the amount of sugar is 20 tons.

The cost when the two companies charge the same is:

5500 + 200.25 * 20 = $9505

So, when the two companies charge the same, the cost is $9505.

Solve m^2 − 6m = 3. Use the Quadratic Formula. Leave your answers as simplified radicals.

Answers

Answer:

To solve m^2 - 6m = 3 using the quadratic formula, we first need to put the equation in standard form, which is ax^2 + bx + c = 0.

m^2 - 6m - 3 = 0

Now we can identify a, b, and c:

a = 1, b = -6, c = -3

Next, we can plug these values into the quadratic formula:

m = (-b ± sqrt(b^2 - 4ac)) / 2a

m = (-(-6) ± sqrt((-6)^2 - 4(1)(-3))) / 2(1)

m = (6 ± sqrt(48)) / 2

Simplifying the square root of 48, we get:

m = (6 ± 4sqrt(3)) / 2

Now we can simplify by factoring out a 2 from the numerator:

m = 3 ± 2sqrt(3)

So the solutions to the equation are:

m = 3 + 2sqrt(3) or m = 3 - 2sqrt(3)

Which pair of points are both located less than 3 units from the point (3,8) on a coordinate grid?

Answers

The required pair of points that are both located less than 3 units from points (3, 8) is (2, 7).

Following the condition given in the question,
Assuming there are 3 points on the graph beside (3, 8) are (2, 7), (5, 5), and (6, 10)

The distance formula between two points is given by:

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

So, for each point, we can plug in the coordinates and simplify the following:

Point (2, 7):

d = √[(2 - 3)² + (7 - 8)²]

d = √[1² + 1²]

d = √2  (<3)

Points (6, 10):

d = √[(6 - 3)² + (10 - 8)²]

d = √[3² + 2²]

d = √13  (>3)

Point (5, 5):

d = √[(5 - 3)² + (5 - 8)²]

d = √[2² + 3²]

d = √13   (>3)

Point (1, 1):

d = √[(1 - 3)² + (1 - 8)²]

d = √[(-2)² + (-7)²]

d = √53  (>3)

Thus, the pair of points that are both located less than 3 units from points (3, 8) is (2, 7).

The function f(x) = 1.85x2 models the cost of a square carpet, where x is the length in feet. Find the average rate of change for f, to the nearest tenth, over the interval 10 ≤ x ≤ 20.

Answers

The average rate of change for function f(x) = 1.85x² to the nearest tenth over the interval 10 ≤ x ≤ 20 is equal to 55.5 (Rounding to the nearest tenth).

Function models the cost of a square carpet

f(x) = 1.85x²

The average rate of change of a function f(x) over an interval [a, b] is,

Average rate of change = [f(b) - f(a)] / (b - a)

The average rate of change of f(x) over the interval 10 ≤ x ≤ 20.

Using the given function, we have,

f(10) = 1.85(10)²

       = 185

f(20) = 1.85(20)²

        = 740

Now calculate the average rate of change,

average rate of change

= [f(20) - f(10)] / (20 - 10)

= (740 - 185) / 10

= 55.5 (Rounding to the nearest tenth)

Therefore, the total amount of money that should be left, including tip, is:

$20 (tab) + $3 (tip) = $23.

An experiment is conducted with a coin. The results of the coin being flipped twice 200 times is shown in the table.


Outcome Frequency
Heads, Heads 40
Heads, Tails 75
Tails, Tails 50
Tails, Heads 35


What is the P(No Heads)?
85%
75%
50%
25%

Answers

The probability representing the no heads in the outcome of flipping a coin 200 times is given by 25%.

Total number of times coin flipped = 200

Number of times we get,

Heads, Heads  = 40

Heads, Tails  = 75

Tails, Tails  = 50

Tails, Heads =  35

The probability of getting no heads that is two tails in a coin toss. Probability is frequency of the outcome 'Tails, Tails' divided by the total number of trials.

⇒P(No Heads) = Frequency of 'Tails, Tails' / Total number of trials

From the table, the frequency of 'Tails, Tails' is 50,

And the total number of trials is 200.

This implies,

P(No Heads)

= 50 / 200

= 0.25

= 25%

Therefore, the probability of the no heads is equal to 25%.

If the diameter of a circle is 8.4 in.. find the area and the circumference of the circle. Use 3.14 for pl. Round your answers to the nearest
hundredth.

Answers

Given that the diameter of a circle is 8.4 inches.

The radius (r) of the circle can be found by dividing the diameter by 2:

r = d/2 = 8.4/2 = 4.2 inches

The area (A) of a circle can be found using the formula:

A = πr^2

Substituting the value of r, we get:

A = 3.14 x 4.2^2 = 55.3896 ≈ 55.39 square inches

The circumference (C) of a circle can be found using the formula:

C = 2πr

Substituting the value of r, we get:

C = 2 x 3.14 x 4.2 = 26.3896 ≈ 26.39 inches

Therefore, the area of the circle is approximately 55.39 square inches and the circumference of the circle is approximately 26.39 inches.

The area of the given circle is 55.39 in² and the circumference is 26.38 in.

We know that the area of a circle is given by the formula A = π×r²

Given the diameter of the circle = 8.4 in

Therefore radius of the circle = 8.4/2 = 4.2 in    (diameter/2 = radius)

Now Area of the circle = π × 4.2²

                                     = 3.14 × 17.64
                                     = 55.3896

                                     = 55.39   (round up to the nearest hundredth)


Circumference of the circle = 2 × π × r

                                              = 2 × 3.14 × 4

                                              = 26.376

                                              = 26.38 (round up to the nearest hundredth)

Therefore the area of the circle is 55.39 in² and the circumference is 26.38 in.

Each week, Nursen saves $5 and shares $3.75. She also spends $4.95 on bus fare to get home from music lessons. This week she earned $24 babysitting. How much money does Nursen have left that she can spend?​

Answers

Answer: In one week, Nursen saves $5 and shares $3.75, so she has $5 + $3.75 = $8.75 per week.

She spends $4.95 on bus fare, so she has $8.75 - $4.95 = $3.80 per week to spend.

This week, Nursen earned $24 babysitting, so she has an additional $24 to spend.

Therefore, Nursen has $3.80 + $24 = $27.80 to spend.

AC =

Answers

We can actually see here that the triangle ABC is an isosceles triangle. This is because two sides of the triangle are equal.

What is an isosceles triangle?

An isosceles triangle is actually a geometric shape having three sides, two of which are equal in length. Consequently, two of the angles that are across from those sides are also equal.

In order to prove that the triangle is an isosceles triangle, we will find the following:

Distance between  vertices A and B:

AB = √((8-5)² + (8-3)²) = √(3² + 5²) = √34 = 5.83mm

Then, we also find the distance between vertices B and C:

BC = √((11-5)² + (3-3)²) = 6mm

Finally, we find the distance between vertices A and C:

AC = √((11-8)² + (3-8)²) = √(3² + 5²) = √34  = 5.83mm

Thus, we see here that AB and AC are actually equal which makes the triangle an isosceles.
