During halftime of a soccer game, a sling shot launches T-shirts at the crowd. A T-shirt is launched from a height of 3 feet
1 answer:
a. 2.1 Seconds
b. 120.6 Feet
c. 3 y
120
Step-by-step explanation:
The height y at time t is
y = 33 + 64t - 16t^2
The general equation that represents the height as a function of time:
f(t) = At^2 + Bt + C
f(t) = -16 + 72t + 3
The maximum height :
t = 72/33 = 2.1sec
So, f(2.1) = -16(2.1) +72(2.1) +3 = 120.6 Feet
Therefore, 2.1 seconds will it take the T-shirt to reach its maximum height
Range of the function ,
heights ( y ) = 3 y
120

Answer:
3¾
Step-by-step explanation:
Geometric sequence also known as geometric progression, can be said to be a sequence with a constant ratio between the terms.
Formula for geometric sequence:
Given:
First term, a1 = 30
ratio, r = ½
Required:
Find the fourth term
Where, the first term, a¹ = 30
Second term: a² = 30 * ½ = 15
Third term: a³ = 15 * ½ = 7.5
Fourth term: a⁴ = 7.5 * ½ = 3.75 = 3¾
Therfore the fourth term of the geometric sequence is 3¾
Let other be x
