Answer is C. y=1/3x+3
the slope is going to be 1/3 (opposite of -3/1) and if go to the point 3,4 and go down one and left 3, you will get a y intercept as 3

The point (-3,3) lies on a circle. What is the length of the radius of this circle if the center is located at (10,6) ?

Amiraneli [1.4K]

The radius is from center to point on a circle.
So your task is count distance between two points: S(10,6) and A(-3,3).
Distance between two points A(x1, y1) and B(x2, y2) count from this formula:
$|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ \hbox{So:} \\ \\ r=|SA|=\sqrt{(-3-10)^2+(3-6)^2}=\sqrt{(-13)^2+(-3)^2}=\sqrt{169+9}= \\ r= \sqrt{178}$

Answer:

f = 6, g = 8

Step-by-step explanation:

The area of Δ ADE = 60 - 48 = 12 cm²

Thus

$\frac{1}{2}$ AD × 4 = 12, that is

2AD = 12 ( divide both sides by 2 )

AD = 6 = f

The area of ABCD = 48 cm² , thus

fg = 48 , that is

6g = 48 ( divide both sides by 6 )

g = 8

Thus f = 6 and g = 8

5. solve for x

miss Akunina [59]

Answer:

x = 17, MN = 11

Step-by-step explanation:

Given 2 secants from an external point to a circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant.

(5)

7(7 + x) = 8(8 + 13) = 8 × 21 = 168 ( divide both sides by 7 )

7 + x = 24 ( subtract 7 from both sides )

x = 17

(6)

9(9 + 2x - 7) = 10(10 + 8)

9(2x + 2) = 10 × 18 = 180 ( divide both sides by 9 )

2x + 2 = 20 ( subtract 2 from both sides )

2x = 18 ( divide both sides by 2 )

x = 9

Then

MN = 2x - 7 = 2(9) - 7 = 18 - 7 = 11
