Answer:
Step-by-step explanation:
y = 4x+2
slope of the line is 4
slope of any parallel to the line is also 4
point-slope equation for line of slope 4 that passes through (8,4):
y-4 = 4(x-8)
rearrange to slope-intercept form:
y = 4x - 28
Area of triangle = 1/2 x base x height
Given that base = 11 yards and height = 13 yards
Area of triangle = 1/2 x 11 x 13 = 71.5 yards²
Answer; 71.5 yd²
You have to do 2 to the third power and then 5 to the second power then times them both to get your answer which is 200^5.
The end of its travel is when S(t)=0 or when it has hit the ground...
-16t^2+25=0 divide equation by -1
16t^2-25, this is a difference of squares which always factors:
(a^2+b^2)=(a+b)(a-b), in this case:
(4t+5)(4t-5)=0, since t>0
t=5/4=1.25, and since it started falling at t=0, its time moving in the air is:
1.25-0=1.25 seconds.
