Answer:
x=3
Step-by-step explanation:
-Find the positive & negative intervals-
x<19/2, x ≥ 19/2
-Solve the inequality for each interval-
x=3, so solving for x, it would equal 3.

Answer:
93 feet
Step-by-step explanation:
Let us first find the time it takes to reach the maximum height. We can do this by differentiating the height function to get velocity:
dh(t)/dt = v(t) = -32t + 72
The maximum height will occur when the velocity becomes 0. Therefore, the time it takes to reach maximum height is:
0 = -32t + 72
32t = 72
t = 72/32 = 2.25 seconds
Therefore, the maximum height of the pumpkin is:
h(2.25) = -16(2.25)^2 + 72(2.25) + 12
h(2.25) = -81 + 162 + 12
h = 93 feet

Find the LCD of 3/4 and 7/10 and rewrite to solve with the equivalent fractions.
LCD = 20
15/20−14/20=1/20 15/20−14/20=1/20
Combining the whole and fraction parts
−1+1/20=−19/20
