There is a division symbol, division is subtracted. Are you sure you have the problem stated clearly?
 $ln( \frac{-5m-3}{ \sqrt{-4m-7} } )\\ \\ ln(-5m-3) - ln( (-4m-7)^{1/2} ) \\ \\ Power Rule \\ \\ ln(-5m-3) - \frac{1}{2} ln(-4m-7)$

Answer: f(8) = 6.25(1.1)^7 ; f(8) = 12.179

Step-by-step explanation: (I got it right on the test)

(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)

r= 1.1

f(1) = 6.25 / starting number

1. Since it is multiplying each number by 1.1 it is using the Geometric Explicit Formula:

f(n)= f(1) x r ^n-1

f(8) = 6.25 x 1.1 ^(8-1)

f(8) = 6.25 x 1.1 ^7

f(8) = 6.25 x 1.9487171

f(8) = 12.179

Answer:

$y= 1.25(2)^{x}$

Step-by-step explanation:

$y= 1.25(2)^{x}$

For x=0

$y= 1.25(2)^{0} = 1.25$

For x=1

$y= 1.25(2)^{1} = 1.25(2)=2.5$

For x=2

$y= 1.25(2)^{2} = 1.25(4)=5$

For x=3

$y= 1.25(2)^{3} = 1.25(8)=10$
