Speed = distance / time
Speed = 50 miles / 4 hours
Speed = 12.5 miles per hour
Answer:
<u><em>Rounded to the Nearest Tenth is V=769.3π </em></u>
Step-by-step explanation:
The diameter of the figure is 7, so the radius is 3.5. So, the radius is 3.5
The height is 20
Formula for cylinders= V= Bh or V=πr2h
I will use V=πr2h
V=π(3.5)²(20)
V=π(12.25)(20)
V=π(245)
<u><em>V=769.3π</em></u>

Answer:
steps below
Step-by-step explanation:
x⁶ - 7x³ - 8 = (x⁶ + x³) - (8x³ + 8)
= x³ (x³+1)-8(x³+1)
= (x³ - 2³)(x³ + 1)
= (x-2)(x²+2x+4)(x+1)(x²-x+1)
(x-2)(x²+2x+4)(x+1)(x²-x+1) = 0
<u>x= -1 or x = 2</u> ... roots
or x²+2x+4=0 or x²-x+1=0
x²+2x+4=0
x = (-2±√4-16)/2 = <u>-1 ± √3 i</u> ... complex roots
x²-x+1=0
x = (1±√1-4)/2 = <u>1/2 ± (√3)i / 2</u> ... complex roots
<u />
b) P(x) = x⁶ - 7x³ - 8
= <u>(x-2)(x²+2x+4)(x+1)(x²-x+1)</u>
= (x+1)(x-2)(x-(-1 + √3 i))(x-(-1 - √3 i)(x-(1/2 + (√3)i / 2))(x-(1/2 - (√3)i / 2))
