The function H(t) = −16t2 + 96t + 80 shows the height H(t), in feet, of a projectile after t seconds. A second object moves in t

mylen [45]

Given that the projectiles have been given by the functions:
H(t)=-16t^2+96t+80 and G(t)=31+32.2t
Part A:
The tables for the functions will be as follows:
t 2 3 4 5
H(t) 208 224 208 160

t 2 3 4 5
G(t) 95.4 127.6 159.8 198

The solution is found between points:
4th second and 5th second

i] It's between this point that the graph H(t) is has reached the maximum point and it's now turning. So the points of H(t) are nearing points for G(t).

Part B]
The solution in part A implicates the times at which the projectiles were at the same height and the time at which they were at the same heights.

The legs of a right triangle measure 7 and x. The<br> hypotenuse measures 25. Determine the value x

777dan777 [17]

According to Pythagoras :

The square of hypotenuse is the sum if the square if the two other side

so : 7^2 + X^2 = 25^2

49 + X^2 = 625

X^2 = 625-49

X^2 = 576

this equation as two roots . As a triangle cannot have a negative side value, I will only take positive value

so X = V576 =24
