Answer:
B 5 seconds
Step-by-step explanation:
h = 240 + 32t – 16t^2
When is this equation 0
0 = 240 + 32t – 16t^2
Factor out 16
0 = -16(-15-2t+t^2)
= -16(t^2-2t-15)
What 2 numbers multiply to -15 and add to -2
-5*3 = -15
-5+3 =-2
0 = -16(t-5) (t+3)
Using the zero product property
t-5=0 t+3=0
t=5 t=-3
Since time cannot be negative
t=5 seconds
Answer:
g(x) = 3x - 3
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
If a line is parallel to another, they have the same slope.
Step 1: Define variables
<em>m</em> = 3
Random pt (2, 3)
y = 3x + b
Step 2: Find <em>b</em>
3 = 3(2) + b
3 = 6 + b
b = -3
Step 3: Write parallel linear equation
y = 3x - 3
