A circle is centered at 7,8 and has a radius of 11 what is the equation?
denis-greek [22]
SchwarzschildRadius here:

So,

The equation for a circle is:

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

Where the center of the circle is (h,k), and the radius of the circle is r.

Substituting 7,8 for (h,k) and 11 for r in the equation gives us:

(x-7)^2+(y-8)^2=11^2

That would be standard form.

Hope this helps!

the area of a rectangle is 85 square feet. the length is 12 feet longer than the width. find the length and width of the wall
Fed [463]
Formula for area of rectangle:
A=L x w
Here A=85 square ft
Length, L=w+12

Put values in formula.
85=(w+12)w
85=w^2+12w
Subtract 85 from both sides
w^2+12w-85=0
Factorise the equation.
(w-5)(w+17)=0
w=5 and w=-17
Ignore the negative value of width.
Width, w= 5 ft  and Length, L=12+5=17 ft

Answer: Width=5 ft and Length=17 ft

Mnenie [13.5K]
Given that DH=4x-2 and FH=x+28, the value of x which will make DEFG a parallelogram will be given as follows;
4x-2=x+28
4x-x=28+2
3x=30
thus
x=30/3
x=10

Hello :) how to do this question?
Ksivusya [100]
Answer:

5(x+4)(x+1)(x-3)

Step by step:

We know that the polynomial has 3 roots -4, -1, & 3.
Therefore the factors of the polynomial are (x+4), (x+1) and (x-3).
Since the coefficients of x^3 is 5

Thus final answer comes out to be

5(x+4)(x+1)(x-3)
