That's an isosceles triangle lying on its side. The base angles (on the left) are marked equal, so we know the sides opposite them are equal.
That means that . . . x+4 = 3x-8
Subtract 'x' from each side . . . 4 = 2x-8
Add 8 to each side . . . 12 = 2x
Divide each side by 2 . . . <em>6 = x</em>
R is -6.
12 = -r +6
12 = 6 - r
12 - 6 = -r
6 = -r
r = -6
Answer:
ok from looking at this equation we can we that every it goes 1 up and on over so
-x+2

Answer:
A) A(t) = 4500*π - 1600*t
B) A(4) = 7730 in³
C) t = 8,8 sec
Step-by-step explanation:
The volume of the sphere is:
d max = 30 r max = 15 in
V(s) = (4/3)*π*r³ V(s) = (4/3)*π* (15)³
V(s) = 4500*π
A) Amount of air needed to fill the ball A(t)
A(t) = Total max. volume of the sphere - rate of flux of air * time
A(t) = 4500*π - 1600*t in³
B) After 4 minutes
A(4) = 4500*π - 6400
A(4) = 14130 - 6400
A(4) = 7730 in³
C) A(t) = 4500*π - 1600*t
when A(t) = 0 the ball got its maximum volume then:
4500*π - 1600*t = 0
t = 14130/1600
t = 8,8 sec
