Semicircle g has center at (-4,0) and radius 2.

Use the general equation for a circle:

(x-h)^2 + (y-k)^2 = r^2

Here, the center is (h,k), where h = -4 and k=0. Also, r = 2

So we have (x-[-4])^2 + (y-0)^2 = r^2 = 4

Let's solve for y in terms of x:

y^2 = 4 - (x+4)^2

Since we are interested in only the bottom half of this circle,

y = - sqrt(4 - x^2 - 8x - 16)

What is the y-intercept of the function f(x) = –2/9x + 1/3?

marishachu [46]

<span>f(x) = –2/9x + 1/3
</span>y -intercept when x = 0
so
f(x) = –2/9(0) + 1/3 then f(x) = 1/3

answer
<span>y-intercept </span>(0, 1/3)

Given:

Alexis has a rectangular backyard that is 50 yards by 55 yards.

She wants to build a fence that stretches diagonally from one corner to the opposite corner.

To find:

The length of the fencing she needs.

Solution:

We have,

Length = 50 yards

Width = 55 yards

We know that, the diagonal of a rectangle is

$Diagonal=\sqrt{length^2+width^2}$

$Diagonal=\sqrt{(50)^2+(55)^2}$

$Diagonal=\sqrt{2500+3025}$

$Diagonal=\sqrt{5525
}$

On further simplification, we get

$Diagonal=74.3303437$

$Diagonal\approx 74.3$

Therefore, the length of the required fencing is 74.3 yards.

Answer:

1/ 5 and 2/3

cross multiple

example

1 2 = 10

/ x / = /

5 3 3

= 10/3

so it's 3 1/3 + 10 Mm

so may guess is

13.3333 infinite or 13.34 M

Dont know if its right but good luck

A teacher writes a simple computer program where she can type students name and computer tells her the students birthday.

Vikki [24]

Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.

<h3>When does a relation represent a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

For this problem, we have that:

The input is the student's name.

The output is the student's birthday.

Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
