The graph below shows the height of a projectile t seconds after it is launched. If acceleration due to gravity is –16 ft/s2, which equation models the height of the projectile correctly? h(t) = at2 + vt + h0

h(t) = –16t2 + 42t + 5
h(t) = –16t2 + 5
h(t) = –16t2 + 32
h(t) = –16t2 + 32t + 5

Step-by-step explanation:

The graph below shows the height of a projectile t seconds after it is launched. If acceleration due to gravity is –16 ft/s2, which equation models the height of the projectile correctly?

h(t) = at2 + vt + h0

h(t) = –16t2 + 42t + 5

h(t) = –16t2 + 5

h(t) = –16t2 + 32

h(t) = –16t2 + 32t + 5

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
