OK. Then let's solve for ' r '. That means you have to come up with an equation that says r = everything else.
Step #1:
Write the equation you're given: <span>S = L (1 - r)
Let's divide each side by ' L ': S/L = 1 - r
Subtract 1 from each side : S/L - 1 = -r
Multiply each side by -1 : <em> 1 - S/L = r</em>
and there you have it.

You can put one figure inside of the other. The figure that is smaller will fit inside of the other figure. Both figures have congruent bases and the same height, so when you put the pyramid inside the prism, their bases overlap exactly. Since the shapes are the same height, the top of the pyramid touches the top of the prism. The pyramid clearly fits inside of the prism, so the volume of the pyramid must be smaller.

Answer:
y-2=3(x+6)
Step-by-step explanation:
you place the axis y and the x in the proper form; y - y1 = 3 ( x - x2)
since axis x is a negative, and in the slope form it is in need of a subtraction, you reverse it; a positive number.
Answer:
-6
Step-by-step explanation:
The average rate of change of a function, f(x), on interval [a,b] is (f(b)-f(a))/(b-a).
So the avereage rate of change of a function, f(x)=x^2+5x+1, on [-9,-2] is
(f(-2)-f(-9))/(-2--9)
(f(-2)-f(-9))/(7)
Stop!
To find f(-2), you replace x in f(x) = x^2 + 5x + 1, with (-2) giving you f(-2)=(-2)^2+5(-2)+1=4-10+1=-6+1=-5.
To find f(-9), you replace x in f(x) = x^2 + 5x + 1, with (-9) giving you f(-2)=(-9)^2+5(-9)+1=81-45+1=36+1=37.
Continue!
(f(-2)-f(-9))/(7)
=(-5-37)/7
=(-42)/7
=-42/7
=-6
