A club collected $3,472 to buy computers. If each computer cost $680, estimate the number of computers that the club can buy.exp

almond37 [142]

The club can buy 5 computers with $3472

Step-by-step explanation:

The number of computers which can be bought from the given amount will be calculated by dividing the amount by price of one computer.

Given

Total amount = $3472

Price of one computer =$680

The number of computers will be:

$=\frac{Total\ amount}{Price\ per\ computer}\\=\frac{3472}{680}\\=5.1\\$

As the number of an item cannot be in decimal it will be rounded off to 5.

The club can buy 5 computers with $3472

Find the inverse of the function. y= √x - 4

EastWind [94]

Answer:

The inverse is $f^{-1}$ (x) = $(x+4)^{2}$

Step-by-step explanation:

(By the way, $f^{-1}$ (x) is f negative one of x, like f(x), but inverse)

f(x) = $\sqrt{x}$ - 4 is the same as y = $\sqrt{x}$ - 4

y = $\sqrt{x}$ - 4 start with the equation.

x = $\sqrt{y}$ - 4 switch x and y.

x + 4 = $\sqrt{y}$ add 4 to both sides.

$(x+4)^{2}$ = y square both sides.

$f^{-1}$ (x) = $(x+4)^{2}$ change y to the inverse f(x) format.

I hope this helps! :)
