Answer:
32 feet
Step-by-step explanation:
The total of ratio units is 3+5+8 = 16. Of those, the longest part is 8/16 = 1/2 of the total length. That is (1/2)·64 ft = 32 ft.
The longest part is 32 feet.
Answer:
t₁ = 2,75 sec
Step-by-step explanation:
The ball will get h maximum when dh/dt ( its vertical component of the speed is equal to 0. At this moment the ball has flown half of the total flight time
Then
h(t) = - 4t * ( 4*t - 11 )
h(t) = - 16*t² + 44*t
Taking derivatives on both sides of the equation we get:
dh/dt = - 32*t + 44
dh/dt = 0 ⇒ -32*t + 44 = 0
t = 44/32 ⇒ t = 1,375 s
So twice this time
2*t = 2 * 1.375
Total time t₁ = 2,75 sec
I keep getting 91, so try C. since it looks more aproximate to the right answer. it looks right even though i might be wrong
18x - 24 > 3 + 2x
16x - 24 > 3
16x - 27 > 0
16x > 27
x < 1.6
All are equivalent to 6(2x-4) > 3 + 2x
