What’s the radius of a circle with an area of 123 square feet
Katyanochek1 [597]

Answer:

6.25716517287

Step-by-step explanation:

Area of circle = π × r²

→ 123 = π × r²

⇒ Divide both sides by π

→ 39.1521160006 = r²

⇒ Square root both sides

→ 6.25716517287 = r

Can you please show work please
-BARSIC- [3]

Answer:

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Step-by-step explanation:

y = mx+b

In slope-intercept form, these are important to know:

- y and x should stay as variables

- m = slope of the line

- b = y intercept

Using the facts above⬆, we can solve these problems

Remember: Substitute m and b using the given information

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Hope this helps :)

Have a great day!

91 more than the square root of a number
Genrish500 [490]

Answer:

Step-by-step explanation:

y = x 2 + 91

Explanation:

Let the number be  x

, then  Square of the number is  x ^2

91 more than the square of a number" will be  x^ 2  +  91

So, we can write it as an algebraic expression with two variables as :

y = x ^2  +  91

What is the length of the line segment with endpoints (11,−4) and (−12,−4) ?
bija089 [108]

Answer:

Length of the line segment with endpoints (11,−4) and (−12,−4)  is 23 units

Step-by-step explanation:

Given:

Endpoints are (11,−4) and (−12,−4)

To Find:

The length of the line = ?

Solution:

The length of the line can be found by using the distance formula

\sqrt{(x_2-x_1)^2 +(y_2 - y_1)^2

Here

x_1= 11

x_2= -12

y_1= -4

y_2= -4

Substituting the values

Length of the line

=>\sqrt{((-12)- 11)^2 +((-4) - (-4))^2

=>\sqrt{(-12- 11)^2 +(-4+4)^2

=>\sqrt{(-23)^2 +(0)^2

=>\sqrt{529}

=>23
