[calculus] the distance from the point (6, -4) to the circle <img src="https://tex.z-dn.net/?f=x%5E2%2By%5E2-8y%3D0" id="TexForm

stealth61 [152]

Answer:

Option C.

The distance from the point to the circle is 6 units

Step-by-step explanation:

we know that

The distance between the circle and the point will be the difference of the distance of the point from the center of circle and the radius of the circle

step 1

Find the center and radius of the circle

we have

$x^{2} +y^{2}-8y=0$

Convert to radius center form

Complete the square

$x^{2} +(y^{2}-8y+16)=0+16$

Rewrite as perfect squares

$x^{2} +(y-4)^{2}=16$

so

The center is the point (0,4)

The radius is

$r^{2}=16\\r=4\ units$

step 2

Find the distance of the point from the center of circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

(6,-4) and (0,4)

substitute the values

$d=\sqrt{(4+4)^{2}+(0-6)^{2}}$

$d=\sqrt{(8)^{2}+(-6)^{2}}$

$d=\sqrt{100}\ units$

$d=10\ units$

step 3

Find the difference of the distance of the point from the center of circle and the radius of the circle

$10\ units-4\ units=6\ units$

therefore

The distance from the point to the circle is 6 units

A company sells T-shirts for $11 each and sweatshirts for $19 each.The number of T-shirts sold was 10 fewer than three times the

Ghella [55]

Answer:

Number of T-SHIRT sold = x = 110

Number of sweatshirt = y = 40

Step-by-step explanation:

Let

Number of T-SHIRT sold = x

Number of sweatshirt = y

The number of T-shirts sold was 10 fewer than three times the number of sweatshirts sold.

x = 3y - 10

Cost of each T-SHIRT = $11

Cost of sweatshirt = $19

Total cost = $1,970

Total = x + y

1,970 = 11(3y - 10) + 19y

1970 = 33y - 110 + 19y

1970 + 110 = 33y + 19y

2080 = 52y

y = 2,080/52

y = 40

Substitute y = 40 into

x = 3y - 10

x = 3(40) - 10

x = 120 - 10

x = 110

Number of T-SHIRT sold = x = 110

Number of sweatshirt = y = 40
