Answer:
volume of the cylinder = 1583.36 
Step-by-step explanation:
where volume of a cylinder = π
h
where h = 14 ft
diameter 12 ft, so radius = 12 / 2 = 6 ft
therefore volume = π *
* 14 = 1583.362697 to the nearest tenths place will be 1583.36

.
Answer:
1. 1/2 +/-√5
2. 1 +/- i √6/2.
Step-by-step explanation:
1. f(x) = 4x^2 - 8x - 1
x = [-(-8) +/-√((-8)^2 - 4*4*-1)] / (2*4)
x =[ 8 +/- √80] / 8
= 1 +/- 4√5/8
= 1 +/- √5/2
= 1/2 +/-√5
2. By a similar method the zeros of the the second equation are:
x = [-(-4) +/- √((-4)^2 - 4*2*5)] / 4
= 4 +/- √(16 - 40) / 4
= 1 +/- √(-24)/4
= 1 +/- i √6 * 2 / 4
= 1 +/- i √6/2.
Ok s we know the total cost is $320 so if the cost for the supplies is $70 the n we will subtract 70 from 320 leaving us with $250. The jobs is 5 hours so we will divide 250 by 5 and get 50 so the total cost per hour is $50
hope this helps!
