The base's length is 8 and it's width is 7, so it's perimeter will be $2\cdot (7+8)=30$ . To find the lateral area you shoul multiply this with it's height. So, $30\cdot h=150\\ h=\frac { 150 }{ 30 } \\ h=5$ (h is height).

Answer:

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

$f(x)=\frac{1}{3} -\frac{1}{21} x$

Switching the positions of the x and f(x) values...

$x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\$

Note: That f(x)^-1 is the proper notation for inverse functions.

$x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7$

There you go!

Hope this helps, and don't procrastinate!

ozzi

Answer:

$P=\frac{C}{4} -5$

Step-by-step explanation:

Step one:

given

cost per drive= $20

additional fee per person= $4

let the number of persons be p

and the total cost be C

The total cost function is expressed as

$C=20+4p$

Step two:

Required:

<u><em>We want to make P subject of the cost function </em></u>

Take 20 to the other side we have

C-20=4p

divide through by 4

P=C-20/4

simplify

P=C/4-5

$P=\frac{C}{4} -5$
