Answer:

Length of the radius of a circle = \sqrt{26}

Step-by-step explanation:

a circle with a center at 2 + 3i and a point on the circle at 7 + 2i

To find the length of the radius, find the distance between the center and a point on the circle

center is 2+3i that is (2,3)

point is 7+2i that is (7,2)

distance formula is \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Plug in the values in the formula

Distance=\sqrt{(7-2)^2+(2-3)^2}

Distance=\sqrt{(5)^2+(-1)^2}

Distance=\sqrt{(26}

Length of the radius of a circle = \sqrt{26}

Distance between 2 points (radius)
= sqrt( (7-2)^2 + (2-3)^2 ) = sqrt(26)

The company charges $5 per sq ft, AND has a minimum charge of 3 sq ft per order (meaning if a customer orders something SMALLER
Sindrei [870]

Answer:

15 dollars

Step-by-step explanation:

12 inches = 1 ft

so 12 inch by 12 inches  is 1 ft * 1 ft

1 ft* 1 ft

1 ft^2

This is smaller than 3 ft^2 so they will get charged for 3 ft^2

3 ft^2 = 3 ft^2 * $5 / ft^2 = 15 dollars

Which equation represents a line that passes through (4, left-parenthesis 4, StartFraction one-third EndFractin right-parenthesi
sladkih [1.3K]

The equation represents a line that passes through(4, 1/3) and has a slope of 3/4 option A; y - 1/3 = 3/4 ( x - 4).

<h3>What is the Point-slope form?</h3>

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

Which is the required equation of a line in a point-slope form.

we know that            

The equation of the line into point-slope form is equal to                        

y-y₁ = m(x-x₁)

             

we have          

(x₁, y₁) = (4, 1/3)

m = 3/4

 

substitute the given values                

y-y₁ = m(x-x₁)

y - 1/3 = 3/4 ( x - 4)

therefore,

y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)

Thus, option A is correct.
