Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes

The radius of the Ferris wheel is 30 / 2 = 15 meters.

The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.

The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.

The angle between these two positions is 180 degrees.

The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.

Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

Answer:

The ratio for the first print job is 150/30 = 5 pages per second.

The ratio for the second print job is 130/20 = 6.5 pages per second.

Since the ratios are different, the data do not represent a proportional relationship. In a proportional relationship, the ratio between two variables remains constant.

Parameter estimates

The coefficient for Px (-5) suggests that there is an inverse relationship between the price of the fruit drink and the quantity demanded. In other words, as the price of the drink increases, the quantity demanded decreases.

The coefficient for M (0.001) suggests that there is a positive relationship between the median annual family income and the quantity demanded. In other words, as the median income increases, the quantity demanded also increases.

The coefficient for Py (10) suggests that there is a positive relationship between the price of the competing brand of fruit drink and the quantity demanded for this brand. In other words, as the price of the competing brand increases, the quantity demanded for this brand also increases.

Step-by-step explanation:

To calculate the monthly consumption of the fruit drink, we plug in the given values into the demand equation,

Qx = 10 - 5(2) + 0.001(20,000) + 10(2.5)

Qx = 10 - 10 + 20 + 25

Qx = 45 liters per family per month.

Therefore, the monthly consumption of the fruit drink per family is 45 liters.

If the median annual family income increased to $30,000, then the new monthly consumption of the fruit drink per family can be calculated as follows,

Qx = 10 - 5(2) + 0.001(30,000) + 10(2.5)

Qx = 10 - 10 + 30 + 25

Qx = 55 liters per family per month.

Therefore, the monthly consumption of the fruit drink per family would increase from 45 liters to 55 liters per family per month.

To determine the demand function, we need to solve for Qx in terms of the other variables,

Qx = 10 - 5Px + 0.001M + 10Py

Qx - 10Py = 10 - 5Px + 0.001M

Qx = (10 - 5Px + 0.001M) / 10Py

Therefore, the demand function is:

Qx = (10 - 5Px + 0.001M) / 10Py

To find the inverse demand function, we need to solve for Px in terms of Qx.

Qx = 10 - 5Px + 0.001M + 10Py

5Px = 10 - Qx - 0.001M - 10Py

Px = (10 - Qx - 0.001M - 10Py) / 5

Therefore, the inverse demand function is,

Px = (10 - Qx - 0.001M - 10Py) / 5

Answer:

25.7

Step-by-step explanation:

The formula to calculate the arc length of a semicircle is given by

Arc Length = (π * radius) + 2 * radius

Substituting the radius value into the formula:

Arc Length = (π * 5) + 2 * 5

Arc Length = 5π + 10

Arc Length = 5(3.14) + 10

Arc Length = 15.7 + 10

Arc Length = 25.7

The circumference of the pizza is approximately 28.27 inches.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The circumference of a circle is given by the formula:

C = πd

where d is the diameter of the circle and π (pi) is a mathematical constant approximately equal to 3.14.

In this case, the diameter of the pizza is 9 inches.

Substituting this value in the formula, we get:

C = πd

C = π(9)

C ≈ 28.27

Therefore,

The circumference of the pizza is approximately 28.27 inches.

Answer:

30 and 60 degrees

Step-by-step explanation:

30 and 60 are complementary angles. 60 is two times the measure of its complementary angle, or 30. 60+30=90.

Complementary angles are angles that add up to 90 degrees.

Angle one = x

Angle two = 2x

2x + x = 90 degrees

Combine like terms.

3x = 90 degrees.

Divide both sides by 3

x = 30

Angle one = x = 30 degrees

Angle two = 2x = 2(30) = 60 degrees.

3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.

To express 3 1/2 cups as a multiplication expression using the unit "1 cup" as a factor, you can write it as:

3 1/2 cups = (3 + 1/2) cups = 3 cups + 1/2 cup

Since there are 1 cup in each term, we can rewrite it as:

3 cups + (1/2) cup

Now, we can express each term as a multiplication expression:

3 cups = 3 * 1 cup = 3

(1/2) cup = (1/2) * 1 cup = 1/2

Putting it all together, the multiplication expression is:

3 * 1 cup + (1/2) * 1 cup = 3 + 1/2

Therefore, 3 1/2 cups can be expressed as the multiplication expression: 3 + 1/2.

The graph of y = x^2 should be translated by 1 unit to the right and 3 units up.

In Mathematics, the translation of a geometric figure to the right simply means adding a digit to the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated upward simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image.

In Mathematics, a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.

Where:

Therefore, we have the following:

f(x) = x^2

g(x) = f(x - 1) + N

\(A=\frac{ab}{2} =\frac{4*6}{2} =12in^2\)

\(A=wl=6*5=30in^2\)

\(12+30=42in^2\)

\(A=\frac{a+b}{2}h=\frac{28+40}{2}*30=1020ft^2\)

Wall = A=\(\frac{ab}{2} =\frac{6*30}{2}=90ft^2\)

Answer:

Step-by-step explanation:

Question 1:

A = (a+b/2)h

A = (4+7/2)3

A = (11/2)3

A = (5.5)3

A = 16.5cm²

Question 2:

A = bh/2 = 6*4/2 = 24/2 = 12

A = bh = 6*5 = 30

A = 12 + 30 = 42

A = 42in²

Question 3:

A = (a+b/2)h

A = (28+40/2)30

A = (68/2)30

A = (34)30

A = 1020ft²

A = bh/2

A = 30*6/2

A = 180/2

A = 90ft²

To calculate a fraction, it is almost the same as calculating a number normal to the power. The numerator and denominator of the fraction are multiplied as many times as possible indicated by its exponent, then:

    \(\boldsymbol{\sf{\left(\dfrac{1}{9}\right)^{2}=\dfrac{1\times1}{9\times9}=\cfrac{1}{81} }}\)

Therefore the fraction 1/81 is already in reduced form, so it is no longer possible to simplify it.

y = 0.3x + 1.8 matches f(x) = 0.1x³ + 2

y = 1.2x + 7.4 matches f(x) = 0.1x³ + 2

y = 2.7x + 3.6 matches f(x) = 0.1x³ + 2

y = 4.8x + 1.8 does not match f(x) = 0.1x³ + 2

y = 4.8x - 10.8 does not match f(x) = 0.1x³ + 2

y = 0.3x - 10.8 does not match f(x) = 0.1x³ + 2
