Answer:
43
Step-by-step explanation:
If x = 4, then plug in an x in the given equation
7(4) + 15 = 43
Therefore h(4) = 43
I hope this helps! :)
Answer:
c = -3
Step-by-step explanation:
7 = -3c -2
3c = -2 -7
3c = -9
c = -3
Answer:
5 seconds
Step-by-step explanation:
When the ball returns to its original height, it will be 96 ft from the ground. That means we want to solve for t ...
h(t) = 96
96 +80t -16t^2 = 96
16t(5 -t) = 0 . . . . subtract 96 and factor
This equation is true for t=0 and for t=5.
After 5 seconds, the ball will pass the top of the building on the way down.
(8 x 320)^1/3
(2560)^1/3
(64*40)^1/3
64^1/3 *40^1/3
4 * (8^1/3) * 5^1/3
4 * 2 * 5^1/3
8 *5^1/3
None of your choices are written correctly
Answer: -75
Explanation: In this problem, we're given the function f(x) = 7x - 5 and we're asked to find f(-10).
To find f(-10) or the value of the function when <em>x = -10</em> we simply substitute -10 in for <em>x</em> in our function.
So we have 7(-10) - 5 or -70 - 5 which equals -75.
So f(-10) or the value of the function when <em>x</em> <em>= 10</em> is -75.
Since your answer to this problem was <em>a</em>, your answer is correct.
