Answer:
r=8
Step-by-step explanation:
59 =7r+3
Subtract 3 from each side
59 -3 = 7r+3-3
56 = 7r
Divide each side by 7
56/7 = 7r/7
8 =r

Answer:
Step-by-step explanation:
circumference of the circle, C=2*3.14*r
C=31.4
31.4=2*3.14*r
r=31.4/(2*3.14)=5

Answer: Choice A</h3>
Explanation:
Choice A has the f(x) values going down on the interval -1 < x < 1 only.
Choice B appears to be decreasing over its entire domain, so we can rule this out (since we want -1 < x < 1 to be the only decreasing interval).
Choice C's table isn't decreasing when -1 < x < 1 since y = -3 increases to y = 0 (from x = -1 to x = 0). So we can rule it out.
A similar situation happens with choice D as well, so we can rule this out. The function isn't decreasing when we go from f(-1) to f(0).
