Answer:
f(x)= - 4 () + 3
Step-by-step explanation:
1. start with f(x)=a(+q
2. in that vertex is (p,q) noticing that use given vertex(0,3) and change the equation/function --> f(x)=a(x-0)+3 --> f(x)=a(+3
3. Then use the give point and substitute to find "a" value --> - 1 = a(+3
--> - 1 = a + 3 --> a= - 4
4. put the "a" value into the #2. function/equation --> f(x)= - 4(+3
Answer:
The area of the new circle is
Step-by-step explanation:
Given:
radius of the circle = 3 in.
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared.
Let
z-----> the scale factor
x-----> the area of the enlarged circle
y-----> the area of the original circle
So;
In this problem we have
----> the scale factor
The area of the original circle is equal to
Now substituting value of y and solve for x we get;
Hence Area of the new Circle is
Also The area of the enlarged circle is 16 times the area of the original circle.
