Answer:
£707.8
Step-by-step explanation:
Given data
Price= £800
Rate= 4%
Time= 3 years
Let us apply the compounding formula
A=P(1-r)^r-------------Note the negative sign is because of depreciation
substitute
A= 800(1-0.04)^3
A= 800(0.96)^3
A=800*0.884736
A= £707.8
Hence the value will be £707.8
In order to solve an equation for a variable, we need to isolate that variable on one side of the equation (either left side or right side).
Following are some steps to solve equation/inequality in one variable:
1) Get rid constant number from on side by applying reverse operation of addition or subtraction.
2) Get rid variable terms from other side by applying reverse operation of addition or subtraction.
3) Combine like terms on both sides.
4) Get rid any coefficent ( a number in front of a variable) by dividing from both sides.
5) Finally you get a variable on one side and solution on other side.
Answer: 9 bookcases
Step-by-step explanation:
943 / 22 = 42.9 = 43 shelves
The number of books that are on the third shelf of the last bookcase is 43/5 = 8.6 = 9 bookcases
There are nine bookcases on the third self.
Answer:
<h2>(f-g)(x) = x² - 3x - 24 </h2>
Step-by-step explanation:
f(x) = x² - 2x - 24
g(x) = x + 4
To find (f-g)(x) subtract g(x) from f(x)
That's
(f-g)(x) = x² - 2x - 24 - ( x + 4)
(f-g)(x) = x² - 2x - 24 - x - 4
Group like terms
We have
(f-g)(x) = x² - 2x - x - 24 - 4
Simplify
We have the final answer as
<h3>(f-g)(x) = x² - 3x - 28</h3>
Hope this helps you
