Answer:
Answer choice A
Step-by-step explanation:
Use the slope intercept form y = mx + b to find the slope m and y-intercept b.
Slope = 4/3
y intercept = (0,-3)
Therefore the answer choice is A, 4/3 ; -3

We are to find how long will it take to return to the ground?
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
Step-by-step explanation:
(2, m) => (n, 5) => (10, 2)
We have 2n = 2 + 10 and 2(5) = m + 2
Hence n = 6 and m = 8.
Answer:
x=4
Step-by-step explanation: area= (2*2)2
Area= 8
Did you mean x^2? Then, the answer is x = +/- 
, which is +/- 25.
