Answer: y = 10(x) + 56

Step-by-step explanation:

y=10(4) + 56

y = 40 + 56

y = 96

Answer:

1a. y = 10 x + 16

1b. 16

2a. y = 600x + 1500

2b. $8700

Step-by-step explanation:

1a. A linear model represents a relationship between two variables as a straight line. In this case, we want to represent the relationship between the number of hours a canoe is rented for and the total cost of the rental, including the deposit.

We can create a linear model by using the equation y = mx + b, where y is the total cost, x is the number of hours the canoe is rented for, m is the slope of the line (the rate at which the cost changes per hour), and b is the y-intercept (the total cost when x is 0).

Since the total cost includes a non-refundable deposit, we need to add this to the y-intercept. The deposit is not dependent on the number of hours the canoe is rented for, so it is not represented in the slope.

Based on the information given, the total cost is $56 when the canoe is rented for 4 hours, and the rental fee is $10 per hour. We can use these values to solve for the y-intercept and the slope:

y = mx + b

56 = (10) (4) + b

56 = 40 + b

b = 56 - 40

b = 16

So the linear model representing the relationship between the number of hours a canoe is rented for and the total cost of the rental, including the deposit, is: y = 10 x + 16

1b. We know that the total cost is $56 when the canoe is rented for 4 hours, and the rental fee is $10 per hour. We can use these values to solve for the y-intercept, which represents the non-refundable deposit:

y = (10) (4) + b

56 = 40 + b

b = 56 - 40

b = 16

So the non-refundable deposit is $16. This means that the total cost of the rental, including the deposit and the hourly fee, is $56.

2a. We can create a linear model by using the equation y = mx + b, where y is the total cost, x is the number of solar heaters produced, m is the slope of the line (the rate at which the cost changes per heater), and b is the y-intercept (the total cost when x is 0).

Based on the information given, it costs $7500 to produce 10 solar heaters, and it costs $13,500 to produce 20 solar heaters. We can use these values to solve for the y-intercept and the slope:

y = mx + b

7500 = m(10) + b

13500 = m(20) + b

Subtracting the second equation from the first equation gives:

-6000 = m(10) - m(20)

6000 = m(20) - m(10)

6000 = m(20 - 10)

6000 = m(10)

m = 6000/10

m = 600

Substituting this value for m in either of the original equations and solving for b gives:

7500 = (600)(10) + b

7500 = 6000 + b

b = 7500 - 6000

b = 1500

So the linear model representing the relationship between the number of solar heaters produced and the total cost of production is:

y = (600) x + 1500

According to this model, the total cost of producing 15 solar heaters would be $10,500.

2b. To find the total cost of producing 12 solar heaters, we can use the linear model that represents the relationship between the number of solar heaters produced and the total cost of production:

y = (600) x + 1500

Where y is the total cost, x is the number of solar heaters produced, m is the slope of the line (the rate at which the cost changes per heater), and b is the y-intercept (the total cost when x is 0).

To predict the total cost of producing 12 solar heaters, we can substitute 12 for x in the equation:

y = (600) (12) + 1500

y = 7200 + 1500

y = 8700

According to this model, the total cost of producing 12 solar heaters would be $8700.

Answer:

the volume of the cone is approximately 28.26 cubic inches.

Step-by-step explanation:

To find the volume of a cone, you can use the formula:

V = (1/3) * π * r^2 * h

where V is the volume of the cone, r is the radius of the base of the cone, and h is the height of the cone.

Using the dimensions provided in the diagram, the radius of the base of the cone is 3 inches and the height of the cone is 8 inches. Plugging these values into the formula, we get:

V = (1/3) * π * 3^2 * 8

= (1/3) * 3.14 * 9 * 8

= 28.26 cubic inches

Product B performed worse in the study because 32% failed to get relief with this product, whereas only 28% failed to get relief with Product A.

Working through this, the percentage who failed to find relief from product A is (25 - 18) / 25 = 28%. Doing the same type of calculation for product B, we can determine the percentage who failed to find relief as (50 - 34) / 50 = 32%. The description statement asks for which offered less relief, which we can find using the less than operator:

28% < 32%

Product A offered relief to all but 28% of the people, while product B offered relief to all but 32% of the people. Given that fewer people failed to find relief on product 28%, we can argue that more people did find relief on product A.

Given that the tests are both on multiples of 25 people, we can also see the percentages by multiplying the numerators and denominators to bring both to a scale of 100:

7/25 * 4/4 = 28% of product A users failed to find relief.

16/50 * 2/2 = 32% of product B users failed to find relief.

The equation g(x) = |-x-3| + 2 would reflect the function over the y-axis.

The required value of f(3) is 10.

Reflection across the y-axis is defined as reflecting a point across they = x,  the x-coordinate, and y-coordinate places, the line y = -x is the coordinates (-x, y).

So reflected across the y-axis: f(x) → f(-x),

⇒ (x,y) → (-x , y)

As per the given question,

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

f(-x) = |-x-3| + 2 = g(x)

Thus, the equation g(x) = |-x-3| + 2 would reflect the function over the y-axis.

The function f(x) is given in the question,

f(x) = 4x - 2,

To determine the value of f(3)

Substitute the value of x = 3 in the given function,

A formula that expresses the connection between two expressions on each side of a sign. Typically, it has a single variable and an equal sign.

Let assume that, x represent the number of pounds of type A coffee that were used in the blend.

and y represent the number of pounds of type B coffee that were used in the blend.

Type A coffee costs Lena $4.10 per pound, and type B coffee costs $5.35 per pound.

The total cost of the mixture is $586.50.

Now,

4.10x + 5.35y = 586.50 ............ (i)

This month's blend used four times as many pounds of type B coffee as type A.

so, y = 4x

Substituting y = 4x into equation (i), we get -

4.10x + 5.35 × 4x = 586.50

or, 4.10x + 21.4x = 586.50

or, 25.5x = 586.50

or, x =  586.50/25.5

Step-by-step explanation:

In this case, the terminal point of theta/2 can be determined using the following steps:

Since cos(theta/2) < 0 and the cosine function has a range of [-1, 1], it follows that theta/2 must be in the second or third quadrant (90 degrees to 180 degrees or 180 degrees to 270 degrees).

To find the terminal point of theta/2, we can use the formula for converting from polar to Cartesian coordinates: x = rcos(theta) and y = rsin(theta), where (x,y) is the Cartesian coordinates of the terminal point, r is the radius, and theta is the angle in radians.

In this case, the radius is 1 (since the terminal point is on the unit circle) and the angle is theta/2. Substituting these values into the formulas above, we get:

x = 1 * cos(theta/2)

y = 1 * sin(theta/2)

To find the values of cos(theta/2) and sin(theta/2), we can use the identity cos(theta/2) = sqrt((1 + cos(theta))/2) and sin(theta/2) = sqrt((1 - cos(theta))/2).

Substituting the given value of cos(theta) (-1/9) and the identities above into the formulas for x and y, we get:

x = sqrt((1 + (-1/9))/2) = -sqrt(2)/3

y = sqrt((1 - (-1/9))/2) = sqrt(8)/3

Thus, the coordinates of the terminal point of theta/2 are (-sqrt(2)/3, sqrt(8)/3).

The terminal point (a₁, a₂) for theta/2 is (-2/3, √(5) / 3).

To find the terminal point (a₁, a₂) of theta/2, use the half-angle identity for cosine:

cos(theta/2) = ± √((1 + cos(theta)) / 2)

Given that cos(theta) = -1/9 and cos(theta/2) < 0, the negative sign should be used in the half-angle identity.

Calculate cos(theta/2):

cos(theta/2) = - √((1 + cos(theta)) / 2)

cos(theta/2) = - √((1 - 1/9) / 2)

cos(theta/2) = - √((8/9) / 2)

cos(theta/2) = - √(8/18)

cos(theta/2) = - √(4/9)

cos(theta/2) = - 2/3

Cos(theta/2) = -2/3. To find the terminal point (a₁, a₂), determine the values of a₁ and a₂.

Since cos(theta/2) is negative, a₁ is negative. To find the value of a₂, use the Pythagorean identity:

cos²(theta/2) + sin²(theta/2) = 1

Since cos(theta/2) = -2/3, calculate sin(theta/2):

sin²(theta/2) = 1 - cos²(theta/2)

sin²(theta/2) = 1 - (-2/3)²

sin²(theta/2) = 1 - 4/9

sin²(theta/2) = 5/9

sin(theta/2) = ± √(5/9)

sin(theta/2) = ± √(5) / 3

Since theta is in the second quadrant (cos(theta) = -1/9), sin(theta) is positive in the second quadrant. Therefore, sin(theta/2) = √(5) / 3.

Now, sin(theta/2) = √(5) / 3.

So, the terminal point (a₁, a₂) for theta/2 is (-2/3, √(5) / 3).
