Answer:
r = 5 ft
Step-by-step explanation:
The circumference of a circle is given by
C = 2*pi*r
We are given the circumference
10 *pi = 2 * pi *r
Divide each side by 2 *pi
10 pi/ 2 pi = 2*pi*r/2pi
5 =r
9. x < −17
10. x < 6
11. 10 < x < 21
12. Move all terms not containing x from the center section of the inequality. No solution.
13. −3 < x < 3
Please give brainliest I worked hard.
Answer:
Step-by-step explanation:
We have that
4x²<span> – 24x+27=0
</span>
Group terms that contain the same variable, and move the
constant to the opposite side of the equation
(4x² – 24x)=-27
Factor the leading coefficient
4*(x² – 6x)=-27
<span>Complete
the square. Remember to balance the equation by adding the same constants
to each side
</span>4*(x² – 6x+9)=-27+
36--------> missing piecesRewrite as perfect squares
4*(x-3)²=9
(x-3)²=9/4----> square root both sides----> (+/-)(x-3)=3/2----> missing pieces
+(x-3)=3/2------> x=(3/2)+3-----> x=9/2
-(x-3)=3/2-----> x=3-(3/2)-----> x=3/2
