Answer:
t = 0.48 sec
Step-by-step explanation:
We are given;
initial velocity; vi = 40 ft/s
hi = 70 ft
acceleration due to gravity; a = 32 ft/s²
Now, we are given that the rocket's height as a function of time is;
h = -12at² + vit + hi
At ground, h = 0
Plugging in the relevant values to obtain ;
0 = -12(32)t² + 40t + 70
-384t² + 40t + 70 = 0
The roots of the equation gives; t = 0.48 sec
Answer:
slope- is negative four -4
and the y-intercept is 4
Step-by-step explanation:
Answer:
Step-by-step explanation:
bh= (2x-6)(x-2)
expand this
2x^2 -10x+12
since formula is 1/2 bh then halve the values
x^2-5x+6
