Answer:
If the price is p and the cost is c, then
15p = 20c
p/c = 20/15 = 1.333
so, he made 33% profit
4v^2 +v -3 = 0 (4v-3)(v+1)=0 4v=3 so v = 3/4 OR v=-1
Answer:
8.0 seconds to the nearest tenth,
Step-by-step explanation:
h=-16t^2 +vt + c.
-16t^2 + 116t + 101 = 0
t = [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)
t = (-116 +/- √19920) / (-32)
t = -0.79, 8.036 (we ignore the negative root)
The time in flight = 8.036 seconds.
The right side of the equation is 6-6 which equals 0.
So the equation could be written as 3x-5y = 0
Since the right side of the equation is zero both the x and y intercepts are (0,0)
