A circle that has a center at the point (3, -2) with a radius of 6. Write an equation for the circle.

crimeas [40]

Answer:

(x – 3)^2+ (y +2)^2 = 36

Step-by-step explanation:

Given data

The formula for the equation of a circle is (x – h)2+ (y – k)2 = r^2,

where (h, k) represents the coordinates of the center of the circle

h=3

k=-2

r= 6

Substitute

(x – 3)^2+ (y – (-2))^2 = 6^2

(x – 3)^2+ (y +2)^2 = 36

Hence the expression for the equation of the circle is

(x – 3)^2+ (y +2)^2 = 36

A farmer sells 7.7 kilograms of apples and pears at the farmer's market.

vagabundo [1.1K]

Answer:

She sold 5.775 kilograms of pears at the farmer's market.

Step-by-step explanation:

Let's first determine the information that the question gives us, and what we need to find.

Given:

The farmer sold 7.7 kilograms of apples and pears

1/4 of the weight is apples

The rest of the weight is pears

Find:

Kilograms of pears that the farmer sold

Start by finding the fraction of the whole weight that was pears...

$1-\frac{1}{4}=\frac{4}{4}-\frac{1}{4}=\frac{3}{4}$

Now, find 3/4 of 7.7...

$\frac{3}{4}(7.7)=\frac{23.1}{4}=5.775\ kg$

She sold 5.775 kilograms of pears at the farmer's market.

Tatiana [17]

Answer:

y = 5

Step-by-step explanation:

Perpendicular means forming a 90 degree angle. In y=5, the line is horizontal and only touches (0,5). When compared to the y-axis, they intersect at 90 degrees so it is y = 5
