  b. true

  c. true

  d. true

  e. false

Step-by-step explanation:

a. False. The "unit rate" is 19.75 gallons per minute. The "unit" of a "unit rate" is in the denominator. Here, the denominator of the rate is 1 minute.

__

b. True. A graph of a proportional relationship is a straight line through the origin.

__

c. True. In 5 minutes, the water in the pool will increase by 98.75 gallons, about 100 gallons.

__

d. True. The ratio of a y-value to an x-value will always be 19.75. That is the meaning of this proportional relationship.

__

e. False. The points (8, 158) or (7.5949, 150) will be on the graph. The point (8, 150) will not.

Given f(x) = 17-X^2what is the average rate of change in f(x) over the interval [1, 5]?
aliya0001 [1]

Answer:

-6

Step-by-step explanation:

The formula for finding the rate of change is:

Rate\ of\ change=\frac{f(b)-f(a)}{b-a}

The interval is [1,5]

So, a = 1 and b=5

f(1) = 17 - (1)^2\\ =17-1\\=16\\f(5) = 17-(5)^2\\=17-25\\=-8

Putting in the values

Rate\ of\ change = \frac{f(5)-f(1)}{5-1} \\=\frac{-8-16}{5-1}\\= \frac{-24}{4}\\ =-6

The average rate of change is -6 ..

Which of these is the algebraic expression for the verbal expression "twelve times the difference of a number and four?"
gavmur [86]

Answer:

12(x - 4)

Step-by-step explanation:

The question says, "twelve times the difference of a number and four"

Let's start with the first number, which is twelve = 12. Moving on, we have times = ×, then the difference which is minus(-). A number is unknown, any aphabet can be used to represent the number, so, we represent with 'x', and then four = 4.

Arranging them, we have:

12 \times x - 4

in algebraic equations, times is always represented by bracket. Therefore, our final answer is:

12(x - 4)

I hope this helps.

Is 9,13,16 a right triangle
Dvinal [7]

We can check by using the

pythagorean theorem or a² + b² = c².

Substitute your values in for <em>a</em>, <em>b</em>, and <em>c</em>.

(9)² + (13)² = (16)²

~simplify

81 + 169 ≠ 256

81 + 169 is 250 but 16² is 256.

So, this in not a right triangle.

The average cost per unit C(x), in dollars, to produce x units of toy cars is given by C(x)=(8000)/(x−50)C(x)=(8000)/(x−50). Wha
podryga [215]
C(x)= \frac{8000}{x-50}

gives an average cost per unit, if we want to produce x of them.

So for example, we want to produce 500 toy cars for our store, and we need a price per unit (per 1 toy car). What we do is we calculate C(500). 

So to calculate the cost of one unit when producing 1250, we calculate C(1250)
 
C(1250)= \frac{8000}{1250-50}= \frac{8000}{1200}=6.67 $ is the cost of 1 toy car.
