Please help, this is algebra and rational export lesson

The correct option is the second one, counting from the top.

Step-by-step explanation:

For a rectangle of length L, and width W, the area can be calculated as:

A = L*W

In this case, we know that:

and

First, we need to remember the relations;

a) Now we can calculate the area of the rectangle as:

And we can write that last part as:

b) Now we want to find the ratio between the width and the length:

Now, if x = 1, the ratio will be equal to 1.

if x > 1, the ratio will be larger than 1.

if  0 < x < 1, the ratio will be smaller than 1.

The correct option is the second one, counting from the top.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
