and B=10.
• Algebra - Steve, Wednesday, April 4, 2012 at 10:50am
R = krB^2
135 = k(3)(3^2) = 27k
k = 5
So, R(r,B) = 5rB^2
R(1,10) = 5(1)(100) = 500

How do you solve for c=3/4y+b, for y? Or 3ax-n/5=-4, for x?
Question
How do you solve for c=3/4y+b, for y? Or 3ax-n/5=-4, for x?
Please
Answer
c = ?y + b; solve for y.
FIRST: subtract b from each side: c-b = ?y+b-b
c-b = ?y
NOTE: to clear fraction in front of the y just multiply bot sides by the reciprocal 4/3

Operations with Functions
Scalar Multiplication
To multiply a function by a scalar, multiply each output by that scalar. For example, if f (x) = 4x - 1 , then f (x) = x - 1) = 2x - . If g(x) = x - 2 , then 3g(x) = 3(x - 2) = 3x - 6 . If h(x) = x ^
2 + 2 , then -2h(x) = - 2(x ^2 +2) = - 2x ^2 - 4 . (3x)h(x) = (3x)(x ^2... | 4 | [

Limits question
hi i am lost in this question. please help: thanks
Set the entire limit equal to y: $y = \lim_{x\rightarrow \infty} (3^x + 3^{2x})^{\frac{1}{x}}$ Take the natural log of both sides: $lny = \lim_{x\rightarrow \infty}[\frac{ln(3^x + 3^{2x}}{x}]$ You
get indeterminate $\frac{\infty}{\infty}$, so use l'Hop... | 5 | [
