Answer:
Step-by-step explanation:
Let
When x = 0, y = 6. So, = k(1 ) = k
Since k = 6 we have
When x = 1, y = 12.
So
b = 2
Therefore, the exponential function is
Answer:
x = 82.1º
Step-by-step explanation:
tan = opp/adj
tan75 = x/22
multiply both sides by 22
22 * tan75 = x
use calculator
82.1051177665153 = x
Rounded
x = 82.1º
After 9 seconds.
(t) = -16t^2 + 1296 // 1296 because that’s the initial height
Now find what value of t makes h(t) equal to 0.
h(t) = 1296 - 16t^2
Use the difference of squares formula
h(t) = (36-4t)(36+4t)
We only take the positive answer, not the negative one (because negative won't make sense here)
36 - 4t = 0
36 = 4t
9 = t
Step-by-step explanation:
1/4x1/4
fraction =1/16
