<span>v = 4/3*pi*r^3
derivating both sides with respect to t
dv/dt = 4*pi*r^2*dr/dt
when d = 1.7, r = 0.85, and dv/dt = 2:
2 = 4*pi*(0.85)^2*dr/dt
thus
dr/dt = 1/(2pi*(0.85)^2)
=1/(2*3.14*0.85^2)
=0.22</span><span />
Factoring out x
x(-3x^2+15x+42) now factor parenthetical expression
x(-3x^2+21x-6x+42)
x(-3x(x-7)-6(x-7))
x(-3x-6)(x-7) we can factor out -3 from first parentheses
-3x(x+2)(x-7)
Answer: The slope is 1
Step-by-step explanation: Rise(how many time u go up) -over- Run (how many times u go over)
Answer:
36 hits
Step-by-step explanation:
Suppose Tony hits the ball x times and Mauricio hits a baseball 4 times as often as Tony each game.
So, Mauricio's hit = 4x
<em />
If Tony hits at the game, then Mauricio will hit 4 times as many times + the 20 at practice on mondays
<h2><em>Equation</em></h2><h3><em>4x + 20</em></h3>
<em />
<em>That means if Tony hit 4, Mauricio will hit </em>
<h2><em>4(4) + 20 = 36</em></h2>
Thus, Mauricio will hit 36 balls this week.

You must divide the larger by the smaller... That will give you the scale factor.
For example: Rectangles 10 x 20 and 5 x 10
the scale factor us 10/5 = 20/10 = 2
Hope this helps.
