Derivative of a constant is 0
Basic Power Rule:
- f(x) = cxⁿ
- f’(x) = c·nxⁿ⁻¹

Answer:
It will take 22 seconds for the thermometer to hit the ground.
Step-by-step explanation:
A thermometer falls from a weather balloon at a height of 7,744 ft.
This means that the initial height is of 7744ft.
h(t) = -16t2 + initial height
So

How many seconds will it take for the thermometer to hit the ground?
This is t for which
. So





It will take 22 seconds for the thermometer to hit the ground.
A prime number is a number that can be ONLY divided by itself and 1
For example - 7 is a prime number as it can be only divided by itself and 1
Hope it helped ❤
I think it's x^4.
(Honestly, I feel 90% positive of this answer, so maybe just get one more opinion!)
<span>Find the difference between ninety-eight and seventy-eight, then multiply by eleven. Ninety-eight minus seventy-eight is twenty, take this and multiply if by eleven to arrive at an answer of eleven. Following the order of operations the math within the parentheses must be done first, then the multiplication. The answer is two-hundred and twenty.</span>
