Answer:$36.40
Step-by-step explanation
16 ounces in 1 pound
0.65 x 16 = $10.40
Peanuts
0.65 x 8 = $5.2 (you do this to get the extra 8 ounces)
$10.40 + $5.2 = $15.6
Pecans
$10.40 + $10.40 = 20.8
Total
$15.6 + 20.8 = $36.40
Answer:
7.012
Step-by-step explanation:
A) We want to know when h=10 so
10=-16t^2+40t+3
16t^2-40t+7=0
Using the quadratic formula:
t=(40±√1152)/32
t≈0.189 and 2.311 seconds
So it is at 10 ft twice, about 2/10 of a second when it is rising and at 2 3/10 of a second when it is falling...
b.
The maximum height of the ball is when velocity is equal to zero, or dh/dt=0
dh/dt=-32t+40, dh/dt=0 when 32t=40, t=40/32=5/4=1.25 seconds
h(1.25)=28ft
So the maximum height of the ball occurs after 1.25 seconds and reaches a height of 28 feet.
