If a shape is scaled by a certain scale factor then :

<u><em>the area of the new shape</em></u> =  (<em>the scale factor</em>) times (<em>the area of the original object</em>)

………………………

the new recreation complex was created by enlarging the old community soccer field by a scale factor of 9

Then

The area of the new recreation complex = 9² × 600 = 81×600 = 48 600 yd²

Write the standard equation of the circle with the given center and passes through the given point. Center (7,-2); Point= (1,-6)
vodomira [7]

Answer:

(x - 7)² + (y + 2)² = (2√13)²

Step-by-step explanation:

We already know that the center is at (7, -2), but must find the radius.  The radius is the distance between the points (7, -2) and (1, -6):

r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.

Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).
just olya [345]
Mathematical Work:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=(2^2-6(2)-7)+8
f(g(2))=(4-12-7)+8
f(g(2))=-7
Explanation:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=?
2 was given as the x for function g and when you substitute 2 into function g's equation(g(2)=(2^2-6(2)-7)=-15, you would get -15. The answer to function g would be the x for function f. Which would be f(-15)=-15+8 and the answer for f(g(2)) is -7.
