A frame is 6in tall and 8 in wide. What if it was reduced to a width of 4in then how tall will it be

kkurt [141]

Answer:

3 in

Step-by-step explanation:

Apparently, we are to assume that the height and width are proportional:

height/width = (6 in)/(8 in) = (new height)/(4 in)

Multiplying by 4 in will tell us the new height:

new height = (4 in)(6/8) = 3 in

The reduced frame will be 3 inches tall.

PLEASE HELP ASAP!! Complete the square to rewrite the following equation. Identify the center and radius of the circle. You must

r-ruslan [8.4K]

Answer:

(i) Center = (-1, -2)

(ii) Radius = 5 units

General Circle Equation:

(x - h)² + (y - k)² = r²

Where:

(h, k) is the center points

r denotes the radius

Rewriting the equation:

$\sf x^2 + 2x + y^2+ 4y = 20$

$\sf x^2 + 2x + 1^2 - 1^2 + y^2 + 4y + 2^2 - 2^2 = 20$

$\sf (x + 1)^2 - 1 + (y + 2)^2 -4 = 20$

$\sf (x + 1)^2 + (y + 2)^2 = 20 + 5$

$\sf (x + 1)^2 + (y + 2)^2 = 25$

$\sf (x -(- 1))^2 + (y -(- 2))^2 = 5^2 \quad \leftarrow \ \bf General \ Circle \ Equation$

Identify the following:

(h, k) = (-1, -2), radius = 5 units
