18 in and 6 in enlarged by 7:2
it will get bigger so 9:12 and 3:9 are not the answers
18×7/2 = 9×7=63 in
6×7/2= 3×7=21in

Answer:

(x-230)^2+(y-220)^2=6100

Step-by-step explanation:

The equation for a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the vertex of the circle and r is the radius. Immediately, since the center of the circle is given, we know what h and k are. h is 230 and k is 220.

The only thing we need to find is the radius, which will just be the distance from the center (230,220) to a point on the circumference (170,170). The distance between them can be calculated using the <u>distance formula</u>, which is really just the <u>Pythagorean Theorem</u> rearranged. The formula states that d=\sqrt{x^2+y^2}, where x is the change in the x-coordinates of the two points and y is the change in the y-coordinates of the two points. Plug-in x for 60 and y for 50 to get d=\sqrt{50^2+60^2}. Solve for d, arriving at \sqrt{6100}. Therefore, the radius of the circle is \sqrt{6100}.

Finally, we have all of the components to create the equation of the circle. Plug-in 230 for h, 220 for k, and \sqrt{6100} for r.

The equation of the circle will be (x-230)^2+(y-220)^2=6100.

Hope this helps :)

Compare the difference between an independent event and a dependent event
Vladimir79 [104]

Independent/Dependent Events. Two events are independent if the result of the second event is not affected by the result of the first event. If and are independent events, the probability of both events occurring is the product of the probabilities of the individual events.

Write the equation of the line with slope 8 and passes through the point ( - 9, - 7)
AleksAgata [21]

Answer:

<h2>y = 9x + 65</h2>

Step-by-step explanation:

To find the equation of the line given the slope and a point we use the formula

y -  y_{1} = m(x - x_{1})

where

m is the slope

( x1 , y1) is the point

From the question the slope is 8 and the point is ( - 9 , - 7)

Substitute the values into the above formula and solve for the equation

We have

y  + 7 = 8(x + 9) \\ y + 7 = 9x + 72 \\ y = 9x + 72 - 7

We have the final answer as

<h3>y = 9x + 65</h3>

Hope this helps you
