I) Find the volume in terms of pie
SVETLANKA909090 [29]

Answer:

i) pi×4500 cm³

ii) pi×600 cm²

iii) 14 liters

Step-by-step explanation:

in general : the diameter is 30 cm, the radius is half of that (15 cm)

i)

the volume of a cylinder is base area times height.

Vc = pi×r²×h = pi×15²×20 = pi×225×20 = pi×4500 cm³

ii)

similar to volume, the side "mantle" area of the cylinder is the circumference of the base area times height.

surface area of the cylinder mantle is

Scm = 2×pi×r×h = 2×pi×15×20 = pi×30×20 = pi×600 cm²

iii)

for this we need now to do the multiplication with pi and then convert the cm³ to liters.

1 liter = a cube of 10 cm side length = 10×10×10 = 1000 cm³

pi×4500 = 14137.17 cm³ = 14.13717 liters or rounded 14 liters

I need help with the answer
solmaris [256]

Answer:

Its the last option

y = 1488.33x + 23800 ; $172,600.

Step-by-step explanation:

The slope of the trend line = (median value for 2000 - median value for 1940) / 60

= 89300 / 60

= 1488.33.

So the equation is 1488.33x + 23,800

Estimate for 2040

is 1483.33* 100 + 23800

= 172,600.

Find all solutions of the equation sin^2 x=2sinx+3
Mashutka [201]
\sin^2x=2\sin x+3
\sin^2x-2\sin x-3=0
(\sin x-3)(\sin x+1)=0

which means either \sin x=3 or \sin x=-1. The equation has no solution, since \sin x is always bounded between -1 and 1. The second has one solution at x=-\dfrac\pi2, and any number of complete revolutions will also satisfy this equation, so in general the solution would be -\dfrac\pi2+2k\pi where k is any integer.

So you could choose A=-\dfrac\pi2 and B=2.
