To solve for the time it reach the maximum height, you must solve the first derivative of the function and equate it to zero
<span>h(t) = −4.9t^2 + 14.7t + 1</span>
dh/ dt = -9.8t + 14.7
then equate to zero
-9.8t + 14.7 = 0
solve for t
t = 1.5 s
then the maximum height is when t = 1.5
<span>h(t) = −4.9t^2 + 14.7t + 1
h(1.5) = </span><span>−4.9(1.5)^2 + 14.7(1.5) + 1
h(1.5) = 12.025 m
</span>
I guess =ay=6-3x= ay/y=6-3x/y= a=6-3x/y
Answer:
The third choice, which would be:
Line 
intersects the line 
.
Step-by-step explanation:
On a graph, line 
and line 
do intersect each other, but not in the x-axis, y-axis, or at the origin.
Product one because it will increase exponentialy
