So make an angle measuring 45 degrees and name it DOG. Its doesn't matter where you start labeling as long as O is the midpoint. :)
4x^2 -28x + 49=0
- move -49 to the other side
x^2-7x+49/4=0
- take out the 4 because you cannot complete the square with a coefficient in front of x^2
(x^2-7x +(7/2)^2) + 49/4 - (7/2)^2 = 0
- complete the square
4((x-7/2)^2)= 0
- bring the 4 back and you’re done.
hope this helped :)
Answer:
30 cm
Step-by-step explanation:
The circumference of a circle is
C = 2*pi*r
60pi = 2* pi *r
Divide each side by 2pi
60/2pi = 2 pi r/ 2pi
30 =r
