First since you know the radius:3 the perimeter of a full circle would be
2pi x 3 = 6 pi. But since it's only half it would be 3 pi.
6+3+3+3pi gets you 12+3 pi
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
3*3^2+2*10^2-15=212
The answer is 212
The shape in the middle is a quadrilateral, so the bottom right hand corner should add up to the rest of the angles to give 360 degrees.
40 + 80 + 110 = 230°
360 - 230 = 130°
The line on which x is on is a straight line, and a straight line is 180 degrees.
Therefore x has to be 180 - 130 to make sure it adds up to give 180 degrees.
180 - 130 = 50
∴ x = 50°
