x = time goal
16% = .16
.16 x = 32
x = 32/.16 = ___________ minutes
Shaded area is everything less than and including the line .
Equation of a line y = mx + b
Line slope m = rise / run = 4/2 = 2 b = -4
y = 2x -4 is the line equation
y <= 2x-4 re-arrange to requested form
-2x + y +4 <= 0 multiply by -1
2 - y -4 >= 0
Volume of box = 20 x 20 x 20 = _________ cm3
Subtract the volume of the b-ball V = 4/3 pi r^3 r =10
Here is a Venn Diagram:
Same here..... happened before....
6t^2 -47t + 30 = 0
Quadratic formula a = 6 b = -47 c = 30
\(t = {-(-47) \pm \sqrt{(-47)^2-4(6)(30)} \over 2(6)}\)
Yields t = 47/12 +- sqrt (1489)/12 You can finish ...I hope
m = slope between the two points
= ( -7 - -1) /(4-5) = -6/-1 = 6
perpindicular slope = - 1/m = - 1/6
150 = h
150 = -16t^2 + 28t + 144
-16t^2 + 28t - 6 = 0 Quadratic formula shows t = 1/4 second ( on the wy up) and 1.5 seconds (on the way down)
Two ......
