Sorry I'm gonna take a guess.......... d?
Answer:
28 will be your answer!
Step-by-step explanation:
I don't properly know how to explain thia but i know its the answer
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
1 cm = 20 feet
the triangle's sides are 4 cm, 5 cm, and 6 cm
multiply the amount of cm with 20 feet
4(20) = 80 feet
5(20) = 100 feet
6(20) = 120 feet
Simplify, divide 10 from all numbers
80/10 = 8
100/10 = 10
120/10 = 12
8, 10, 12 is your answer
hope this helps
The first 7 or the second one ?
