Fo a circle with radius, r and center (h,k)
te equation is
(x-h)²+(y-k)²=r²
d/2=r
8/2=4=r
center is (-2,-3)

(x-(-2))²+(y-(-3))²=4²
(x+2)²+(y+3)²=16

Answer:

Equation of circle is  (x + 2) ²+ ( y + 3)² = 4².

Step-by-step explanation:

Given  : a circle with a center at (-2,-3) and a diameter of 8 units.

To find : Which equation represents the general form of a circle .

Solution : We have given  center at (-2,-3) and a diameter of 8 units.

Radius = \frac{Diameter}{2}.

Radius =  \frac{8}{2}.

Radius = 4 units.

Standard form of circle is  (x -h) ²+ ( y -k)² = r².

Where,  ( h, k) is center , r =  radius .

Plug center ( -2 ,-3) and  r = 4 .

 (x - (-2)) ²+ ( y - (-3))² = 4².

 (x + 2) ²+ ( y + 3)² = 4².

Therefore, Equation of circle is  (x + 2) ²+ ( y + 3)² = 4².

. A square picture frame occupies an area of 112 ft2 . What is the length of each side of the picture in simplified radical form
saw5 [17]
Recall that a square is just a rectangle with all sides equal.

and the area of a rectangle is just length * width.

\bf \textit{area of a rectangle}\\\\
A=length\cdot width\quad 
\begin{cases}
length=x\\
width=x\\
A=112
\end{cases}\implies 112=x\cdot x\implies 112=x^2
\\\\\\
\sqrt{112}=x\implies \sqrt{16\cdot 7}=x\implies \sqrt{4^2\cdot 7}=x\implies 4\sqrt{7}=x

A segment with endpoints A (3, 4) and C (5, 11) is partitioned by a point B such that AB and BC form a 2:3 ratio. Find B.
Dima020 [189]

Answer:

(3.8, 6.8)

Step-by-step explanation:

Point B:

Has coordinates (x,y)

AB and BC form a 2:3 ratio.

This means that:

B - A = \frac{2}{2+3}(C - A)

B - A = \frac{2}{5}(C - A)

We apply this both for the x-coordinate and for the y-coordinate.

x-coordinate:

x-coordinate of A: 3

x-coordinate of C: 5

x-coordinate of B: x

B - A = \frac{2}{5}(C - A)

x - 3 = \frac{2}{5}(5 - 3)

x - 3 = \frac{4}{5}

x = 0.8 + 3 = 3.8

y-coordinate:

y-coordinate of A: 4

y-coordinate of C: 11

y-coordinate of B: y

B - A = \frac{2}{5}(C - A)

y - 4 = \frac{2}{5}(11 - 4)

y - 4 = \frac{14}{5}

y = 2.8 + 4 = 6.8

Thus the correct answer is:

(3.8, 6.8)

Explain how to use multiplication to find
Sindrei [870]

A fraction x/y is a ratio between two numbers x and y.

The ratio is preserved if both x and y are scaled up or down by the same number n.

This means you can obtain any fraction equivalent to x/y by multiplying both x and y by n, i.e. (n*x)/(n*y).

Then we have 1/4 = (2*1)/(2*4) = 2/8, for example.
