Write the equation of a circle with diameter endpoints of (-14,1) and (-10,9)

lara31 [8.8K]

Answer:

$(x+12)^2+(y-5)^2=80$

Step-by-step explanation:

First, we see that the center of the circle is (-12, 5) by taking the midpoint of the circle. Secondly, the length of diameter is $\sqrt{4^2+8^2}=\sqrt{80}$ .

You are enclosing a rectangular garden with 60 feet of ornamental fencing. the area of the garden is 200 square feet. what are t

Lilit [14]

The perimeter is equal to 60 feet and has the formula:

Perimeter = 2 l + 2 w

60 = 2 l + 2 w

The area is equal to 200 square feet and has the formula:

Area = l w

200 = l w

Rewriting area in terms of l:

l = 200 / w

Combining this with the perimeter formula:

60 = 2 (200 / w) + 2 w

60 = 400 / w + 2 w

Multiplying all by w:

60 w = 400 + 2 w^2

Dividing by 2 and rearranging:

w^2 – 30 w = - 200

Completing the square:

(w – 15)^2 = - 200 + (-15)^2

(w – 15)^2 = 25

w – 15 = ±5

w = 10, 20

Hence the dimensions of the garden is 10 feet by 20 feet

Convert 7x + 3y = −1 to slope-intercept form.

maksim [4K]

Hi there!

Let's solve this problem step by step!

$7x + 3y = - 1$
To convert this formula to slope-intercept form, we must isolate y.

First bring 7x to the left by subtracting 7x from both sides of the equation.
$3y = - 7x - 1$

Finally we need to divide both sides of the equation by 3.
$\frac{3y}{3} = \frac{ - 7x - 1}{3}$

Do some simple algebra and we find:
$y = - \frac{7}{3} x - \frac{1}{3} \\ y = - 2 \frac{1}{3} x - \frac{1}{3}$
~ Hope this helps you!
