Answer:
r= 4 ft
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is
16 pi = pi r^2
Divide each side by pi
16 pi/pi = pi r^2/pi
16 = r^2
Take the square root of each side
sqrt(16) = sqrt(r^2)
4 =r
Answer:
14
Step-by-step explanation:
f(x)=2x+7
f(4)=2(4)+7
=8+7
=15
f(-4)=2(-4)+7
=-8+7
=-1
f(4)+f(-4)
=15+(-1)
=14.
2000 for RF and IT and EF per month...
30% goes to retirement.....0.30(2000) = 600
IT is 80% of RF.....0.80(600) = 480
remainder goes to EF.......2000 - (600 + 480) = 920
which represents 20% of his salary...
920 = 20% of salary (s)
920 = 0.20s
920/0.20 = s
4600 = s.........he earns 4600 per month <==
It stretches the graph parallel to the y axis by a factor a. This has the effect of making the parabola more narrow.
0.009833
Or you mean 2,949 divided by 29 which is 101.6896
