Step-by-step explanation:

Answer:Its most likely to be D

Step-by-step explanation:

An office supply store purchased a case of binders for $600. The profit (P) to be made on the binders is defined by the function
P(b) - 8.50b - 600, where b is the number of binders sold.
Part A What is the range of the function if the domain is {10, 45, 72, 100)?
Part B What do the domain and range represent in this situation?
Part C What is the minimum number of binders that the store needs to sell in order to make a profit (P >0)? Show or explain your work.
Part D What is the minimum profit the store can make on the sale of these binders? Show or explain your work.

Answers

Answer:

Part A

Domain = input values

Range = output values

Therefore, if the domain is {10, 45, 72, 100} then input those values into the function:

P(10) = 8.50(10) - 600 = -515

P(45) = 8.50(45) - 600 = -217.5

P(72) = 8.50(72) - 600 = 12

P(100) = 8.50(100) - 600 = 250

So the range is {-515, -217.5, 12, 250}

Part B

The domain is the number of binders sold

The range is the profit in dollars

Part C

Set the function to >0:

⇒ P(b) > 0

⇒ 8.50b - 600 > 0

add 600 to both sides:

⇒ 8.50b > 600

divide both sides by 8.50:

⇒ b > 70.58823529...

Therefore, the minimum number of binders the store needs to sell in order to make a profit is 71.

Part D

If the store sells a minimum of 71 binders, then substitute b = 71 into the function and solve to find the minimum profit:

⇒ P(71) = 8.50(71) - 600

⇒ P(71) = 603.5 - 600

⇒ P(71) = 3.5

Therefore, the store will make a minimum of $3.50 profit if it sells at least 71 binders.

However, if the store sells less than 71 binders, it will make a loss.

Answers

Answer:

m = 2.4 and b = 14.8

Step-by-step explanation:

In slope-intercept form, all equations follow the formula y = mx + b, in which equations are parallel as long as they have the same slope, represented by the variable m. All that the b variable does is change the y-intercept. Knowing this, in order to find a parallel equation to y = 2.4x + 5.2 that intercepts the point (-2, 10), the only variable that can change is the b variable. The first step is to plus -2 into the x variable. This will grant you y = 2.4(-2) or y = -4.8, which will then allow you to find what the b variable should be by subtracting -4.8 from 10. This will grant you b = 14.8, and since you know the slope must stay the same, the final answers are m = 2.4 and b = 14.8.

The areas of the two rectangles below are equal. There are two possible areas. One is 105 u2

What is the other one?

Answers

Answer:

144 u²

Step-by-step explanation:

⇒ Areas are equal

(6x + 15)(2x + 7) = (4x + 7)(2x + 15)12x² + 42x + 30x + 105 = 8x² + 60x + 14x + 1054x² = 2xx = 1/2

Calculating the areas

(6 x 1/2 + 15)(2 x 1/2 + 7) = 18 x 8 = 144(4 x 1/2 + 7)(2 x 1/2 + 15) = 9 x 16 = 144

​Dolbear's law states the relationship between the rate at which Snowy Tree Crickets chirp and the air temperature of their environment. The formula is ​T=50+n-40/4, where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute. If T​=57°F, find the number of chirps per minute.

Answers

Answer:

Number of chirps per minute = 68

Step-by-step explanation:

Given:

​T = 50+ (N - 40)/4

where,

T is a temperature in degrees Fahrenheit

N is a number of chirps per minute

Find n when T = 57°F

​T = 50 + (N - 40)/4

57 = 50 + (N - 40)/4

57 - 50 = (N - 40)/4

7 = (N - 40)/4

Multiply both sides by 4

7 × 4 = (N - 40)/4 × 4

28 = N - 40

28 + 40 = N

68 = N

N = 68

Number of chirps per minute = 68
