Answer:
First evaluate 4^t
put x= 1 in 4^x
It's 4^1 = 4 but f(x) = 8
So we need to multiply with 2
So it's A) 2.4^x
Answer:
187
Step-by-step explanation:
9y=99
y=11
17y=x
x=187
Answer: 66
Step-by-step explanation:
6+4^3-8÷2
4^3 = 64
6+64-8÷2
70-8÷2
70-4 = 66
Answer:
The answer to your question is 2 seconds
Step-by-step explanation:
Data
function y = -14x² + 56x
maximum height = ?
Process
1.- Find the derivative of the function
y' = -28x + 56
2.- Equal to zero the result
-28x + 56 = 0
3.- Solve for x
-28x = - 56
x = -56/-28
x = 2
4.- Conclusion
It takes to the ball 2 seconds to reach the maximum height.
