The one-to-one functions g and h are defined as follows.
Ad libitum [116K]

Answer:

Step-by-step explanation:

The one-to-one functions g and h are defined as follows.

g={(-7,-6), (-5,4), (4,-7)(7,6)}

h(x)= 3x-14

Find the following.

g-1(4)=

"g-1(4)" just says "Find the pair of coordinates that has 4 for its

y-coordinate, and the answer is its x-coordinate".  So we look through those

and find (-5,4) is the only one of those up there that has a 4 for it's y-

coordinate, and so its x-coordinate is -5 and we write:

g-1(4)=-5

A paper cup shaped like a cone has a diameter of 6 centimeters and a slant height of 7.5 centimeters. About how much paper is ne
liq [111]

Answer:

22.5 cm^2

Step-by-step explanation:

Amount of paper is going to be measured in area, so we want the surface area of the cone.  Since it is a cub it doesn't have a base, so we don't need to count it.  

Area of the cone without the base, or what is called the lateral area is pi*r*s where r is the radius and s is the slant height.  and of course radius is d/2 where d is the diameter.  so let's plug it in.  We know diameter is 6 and slant height is 7.5

SA = pi * r * s

SA = pi * d/2 * s

SA = pi * 6/2 * 7.5

SA = 22.5 cm^2

So you will need 22.5 square centimeters of paper.

You are wallpapering a wall 10 feet wide and 12 feet high with a square window with 3 foot sides. How many square feet of wallpa
kolbaska11 [484]
Hey there!


First you need to see how much you need to buy, and when you do 10 x 12 = 120.


So you need at least 120 feet to cover the wall.
 Now you have to factor in the wall, when you do 3 x 3 (B x H) = 9.
Now do, 120 - 9 = 111.

So you need 111 square feet to cover the wall.

Hope this helps!
