Answer:
4.47100222
Step-by-step explanation:
157/2.5=62.8
62.8/pi= 19.98986085
square root the answer above and you get 4.47100222 for the radius
<span>[ (3x6) ] + (5x2) ] ÷ 7
= (18 + 10)/7
= 28/7
= 4</span>
L=2W+3, A=LW, using L from the first in the second gives you:
A=(2W+3)W
A=2W^2+3W, and we are told A=90 so
2W^2+3W=90
2W^2+3W-90=0
2W^2-12W+15W-90=0
2W(W-6)+15(W-6)=0
(2W+15)(W-6)=0, since W>0 for all real possibilities,
W=6ft, and since L=2W+3
L=15ft
So the pool will be 6 ft wide by 15 ft long.
Answer:
343 - 64 + 457 Solve then you get your answer
Answer:
a(n) = a(n-1) + 4
Step-by-step explanation:
a(1) = 2 The first term is 2
a(n) = a(n-1) + 4 We add 4 to the previous term or n-1
So, we get...
a(n) = a(n-1) + 4
a(1) = 2
a(2) = a(2-1) + 4 2(1) +4 = 6
a(3) = a(3-1) +4 3(2) + 4 = 10
and so on and so forth. I hope this helps.
