10. Which is the logarithmic form of 6^4 = 1296?

log4 1296 = 6
log 1296 = 4 * 6
log6 1296 = 4**
log 1296 = 4
13. For the function f(x) = sqrt(x-6), find the inverse function.

ƒ−1(x) = −x^2 + 6
ƒ−1(x) = x^2 − 6
ƒ−1(x) = x^2 + 6**

16. Suppose that y varies inversely with x. Write a function that models the inverse function.

x = 25 when y = 5

y = 5x
y = 5/x
y = 125x
y = 125/x
17. Which function represents exponential decay?

20.
For the function ƒ(x) = 4x − 3, evaluate and simplify the expression: f(a+h) - f(a) / h
f(a+h) - f(a) / h = 4h
f(a+h) - f(a) / h = 4a + 4h + 3
f(a+h) - f(a) / h = 4a + 4h - 3
f(a+h) - f(a) / h = 4**

Answer 2

@xapproachesinfinity mind helping? Btw, did you get my email?

Answer 3

is this a test???

Answer 4

No, it's a practice work. I just want to make sure my answers are correct.

Answer 5

well...dont you know is 1 question per post

Answer 6

i know not 2 put test here

Answer 7

post one question at a time my friend!

Answer 8

alright hold up

Answer 9

can you answer one real quick?

Answer 10

i'm saying this because i cannot help with them all i'm busy
also people won't like to help with all of your questions at once like this

Answer 11

oh okay

Answer 12

for the first one the conditions are somehow wrong
in quadrant II which you chose have both csc and sin are positive
that does not go with what you have

Answer 13

this where singe get negative

Answer 14

but csc has the same sign so i think something is off with your conditions something is not right

Answer 15

sorry open study crushed

Answer 16

So is it lV?
