When you multiply two exponential terms what do you do with the exponents?
You add them
k+h-6
use k=7, h=8
9
Which term is the 'c' term in the following equation
-16x^2+18x+490
490
Find the 14th term
4, 9, 14, 19, . . .
69
Convert to rational form
1/x+2 +3
3x+7/x+2
Simplify
log 2+ log 23
log(46)
solve for k
-22-7k = k-6
k=-2
Mikey jumped off a cliff into the ocean. His height as a function of time could be modeled by the function h(t)=-16x^2+18x+490
How long did it take Mikey to reach maximum high?
.56

12,72,432, . . .
725594111
Convert using long division
2x^2+12x+24/X^2+6x+9
x/(x+3)^2+2
Simplify and solve for x
log 9+ log 26- log 6=x
log(228)
x=2.36
Q=2, R=6, M=10
QR(M+M)^2
