SOMEONE PLEASE HELP! Can someone show me how to work this out?

Mathematics

Vladimir [108]2 years ago

Answer:

2/(x+7)

Step-by-step explanation:

x²+5x-14 factors as (x-2)(x+7)

SO - multiply the fraction on the right by x+7 (both top and bottom)

Then both have the same denominator (x-2)(x+7), and the 1 becomes x+7.

Then you combine the fractions to make ((3x+3)-(x+7))/(x-2)(x+7).

This becomes (2x-4)/(x-2)(x+7).  

You can factor the 2 out of the numerator for 2(x-2).

You now have 2(x-2)/(x-2)(x+7)

The (x-2)’s cancel out and you are left with

2/(x+7)

For accounting purposes, the value of assets (land, buildings, equipment) in a business are depreciated at a set rate per year.
lidiya [134]

Answer: $ 125987.80

Step-by-step explanation:

Given: The value, V(t) of $393,000 worth of assets after t years, that depreciate at 15% per year, is given by the formula

V (t)=V_o(b)^t, here V_o is the initial asset value  and b is the multiplicative decay factor.

The exponential decay function is given by ;-

f(x)=A(b)^x, where A is the initial value , x is the  times period and b is the multiplicative decay factor.

where b = 1-r, r is the rate of decay.

Since r = 15%=0.15

Therefore, b = 1-0.15=0.85

Now ,for 7 years , the value of assets is given by :-

V=393000(0.85)^7=125986.795\approx125987.80

Hence, the assets valued at after 7 years = $ 125987.80
