Step-by-step explanation:
Step-by-step explanation:
The Answer Is
-4d + 7 = 3d
So, 7 = 3d + 4d
Then, 7 = 7d
•d = 7/7
= 1
So D = 1.
x(t) = 20t
y(t) = 40t - 5t^2
Since we are only interested in comparing the two at time t = 5 seconds, we plug in 5 everywhere we see the variable t and then compare x and y
x(5) = 20(5) becomes x(5) = 100
y(5) = 40(5) - 5(5)^2 becomes y(5) = 200 - 125 and then y(5) = 75
The ratio of y to x can be expressed as: y/x, so we can say the ratio is equal to 75/100 or 0.75
Answer: 0.75
