Answer:
i don't know. sorry!
Step-by-step explanation:
Answer:
See below.
Step-by-step explanation:
The rocket's flight is controlled by its initial velocity and the acceleration due to gravity.
The equation of motion is h(t) = ut + 1.2 g t^2 where u = initial velocity, g = acceleration due to gravity ( = - 32 ft s^-2) and t = the time.
(a) h(t) = 64t - 1/2*32 t^2
h(t) = 64t - 16t^2.
(b) The graph will be a parabola which opens downwards with a maximum at the point (2, 64) and x-intercepts at (0, 0) and (4, 0).
The y-axis is the height of the rocket and the x-axis gives the time.
Maximum height = 64 feet, Time to maximum height = 2 seconds, and time in the air = 4 seconds.
The first one: r + 6 is greater than or equal to 45
Answer:
B (6, 8)
C (1, 5)
see attached diagram (qu 1 is blue, qu2 is red)
Step-by-step explanation:
1.
A = (2, 3)
If B is 4 right and 5 up from point A, then
B = (2 + 4, 3 + 5) = (6, 8)
2. C = (9, 7)
If D is 8 left and 2 down from point C, then
C = (9 - 8, 7 - 2) = (1, 5)
