What is the length of a radius of the circle represented by the equation below?
MakcuM [25]

Answer:

2

Step-by-step explanation:

Given the circle: x^2 + y^2 - 4x - 4y + 4 = 0

To determine the length of the radius, we complete the square.

Step 1: Subtract 4 from both sides

x^2 + y^2 - 4x - 4y + 4 -4= 0-4\\x^2 + y^2 - 4x - 4y = -4

Step 2: Divide the coefficient of x and y by 2, square it and add it to both sides

x^2 - 4x+(-2)^2+ y^2  - 4y+(-2)^2 = -4+(-2)^2+(-2)^2

Step 3: Factorize the Left Hand side and simplify the Right Hand side.

(x-2)^2+ (y-2)^2 = 2^2

Comparing with the standard form of the equation of a circle

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

r=2

Therefore, the radius of the circle is 2.

You need to construct fence around an area of 3136 ft2. What are the dimensions of the rectangular pen that minimize the amount
borishaifa [10]

Answer:

Step-by-step explanation:

The the area of the rectangular pen be A = LW

L is the length

W is the width

Given

A = 3136ft²

3136 = LW..........1

Given the perimeter P = 2L+2W....... 2

From 1; L = 3136/W

Substitute into 2

P = 2(3136/W)+2W

P = 6272/W + 2W

In order to minimize the amount of material needed, then dP/dW = 0

dP/dW = -6272/W² + 2

0 = -6272/W² + 2

6272/W² = 2

cross multiply

6272 = 2W²

W² = 3136

W = √3136

W = 56ft

Since A = LW

3136 = 56L

L = 3136/56

L = 56ft

Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft

At a local park, Jared can choose between two circular paths to ride his bicycle. One path has a diameter of 240 yards, and the
amid [387]

Answer:

94.2 yards

Step-by-step explanation:

1st path = d = 120 yards

c= pie d

c= 376.8 yards

2nd yard = r = 45 yards

c = 2 pie r

c = 2(3,14)(45)

c = 282.6 yards

then subtract yard 1 and yard 2 to get 94.2 yard

ANSWER :94.2 yards

sineoko [7]

Answer:

12

Step-by-step explanation:

Since 19% of the eggs are yellow,

then 19% of 63 = 11.97

Since eggs have no fractions, then the mean number of expected yellow eggs is 12.
