Answer:

Step-by-step explanation:

A: is not the answer. The answer is √144 which is 12

B: is correct. You can do it this way, by breaking the 9 and 16 apart.

C: I don't know exactly what the logic of 36 is, but it is not the right answer.

D: I can't explain why the choice would be division. It is multiplication of some sort. D is incorrect.

What is the value of 4 x minus 7 when x = 4?
Stolb23 [73]

Answer: 9

Step-by-step explanation: Here, we have the expression <em>4x - 7</em> and we want to evaluate the expression when <em>x</em> is equal to 4.

To evaluate an expression, we simply plug the value

of the variable into the expression and solve.

So here, since <em>x</em> is equal to 4, we have 4(4) - 7.

4(4) is equal to 16.

So we have 16 - 7 which is equal to 9.

So the value of our expression when <em>x</em> is equal to 4 is 9.

you have a bottle with a leak . after 2 seconds there are 28 ounces left in the bottle. after 6 seconds , there are 20 ounces le
Arte-miy333 [17]
We determine first the rate of flow of water out of the bottle by dividing the difference in the volume with the difference in time. 
                           r = (28 - 20) / (6 - 2)
                             r = 2 ounce/s
We calculate the first term by adding 2 ounce/s to the 2nd term, giving us the answer which is equal to 30 ounce/second.

Need Help on Pre Cal

<h3>Answer: 17</h3>

======================================================

Explanation:

This is a piecewise function. It's composed of 3 pieces of other functions. A piecewise function is a function that changes its identity based on what the input is.

We have three different situations here

  • If t = 17, then h(t) = sqrt(17t) based on what the first row says
  • If t = 19, then h(t) = -34/t which is the second row of the piecewise function.
  • If t does not equal either 17 or 19 (ie t is anything but those values), then h(t) = 23-t

The notation h(17) means we want to evaluate h(t) when t = 17. So we'll use the first case mentioned above. Plug t = 17 into h(t) = sqrt(17t) to get...

h(t) = sqrt(17t)

h(17) = sqrt(17*17)

h(17) = sqrt(17^2)

h(17) = 17

In the last step, I used the rule that sqrt(x^2) = x when x is nonnegative.
