Answer:
1430
Step-by-step explanation:
S=450+70T
S= 450 + 70(14)
S=450+980
S=1430
The property of 16 + 31 = 31 + 16 is called Commutative Property.
The property states that the order does not matter. This includes both multiplication and addition. Other examples include 4 + 2 = 2 + 4, or even 10 + 9 + 3 = 3 + 9 + 10. In easier words, the problem is just the backwards version of the original problem.
Given that the height of the ball has been modeled by h=120t-16t^2, the reasonable range will be found as follows:
maximum height is attained when h'(t)=0
given h=120t-16t^2
h'(t)=120-32t=0
thus solving for t, we get:
t=3.75 sec
thus the maximum time attained will be:
120(3.75)-16(3.75)^2=225 ft
Therefore the reasonable range will be [0≤h(t)≤225]
