Given:
h(t) = -16t² + 90t + 50
g(t) = 28 + 48.8t
h(1) = -16(1²) + 90(1) + 50 = 124
h(2) = -16(2²) + 90(2) + 50 = -64 + 180 + 50 = 166
h(3) = -16(3²) + 90(3) + 50 = -144 + 270 + 50 = 176
h(4) = -16(4²) + 90(4) + 50 = -256 + 360 + 50 = 154
g(1) = 28 + 48.8(1) = 76.80
g(2) = 28 + 48.8(2) = 125.60
g(3) = 28 + 48.8(3) = 174.40
g(4) = 28 + 48.8(4) = 223.20
Between 3 seconds is the answer... though it is not exactly equal but they are nearer in value compared to other number of seconds.
E + 10 = P
(P + 5) = 2(E +5)
E = P -10
P + 5 = 2((P-10)+5)
P + 5 = 2P -20 + 10
P + 5 =2P - 10
-P = -15
P = 15
The last one (D) is not right. The corresponding lines share the same ratio but they need not be equal.
D <<<< answer.
