Find the volume of a cylinder
you (pi)(r^2)(height)
(3.14)(1.5^2)(6)= 42.39
42.4 is how much it can hold
Answer:
<u>The correct answer is D. -5 +/- i√2</u>
Step-by-step explanation:
Let's solve for x, the equation given to us, this way, using the quadratic formula:
x = (- b +/- √b² - 4ac)/2a
Replacing with the real values, we have:
x = (-10 +/- √10² - 4 * 1 * 27)/2
x = (-10 +/- √100 -108)/2
x = (-10 +/- √-8)/2
x = (-10 +/- √-1 * 4 * 2)/2 Let's recall that √-1 = i
x = (-10 +/- 2i√2)/2
x = 2 (-5 +/- i√2)/2 (Dividing by 2 both the numerator and the denominator)
<u>x₁ = -5 + i√2</u>
<u>x₂ = -5 - i√2</u>
<u>The correct answer is D. -5 +/- i√2</u>
Answer:
26
Step-by-step explanation:
First take your too fractions.
6 1/2
1/4
Divided 6 1/2 by 1/4 to get your answer!
You need to find out how much it costs to wash one car, so:
3×=13.50
Divide both sides by 3.
x=4.5 per car.
Now multiply 4.5 by 25 which should give you $112.50
Answer:
See below.
Step-by-step explanation:
1.
PM as the number or rows not equal to coloumn
2.
1*2 as MN = ( 32 )
( 61 )
3.
= ( 4x2+7x4 4x3+7x8 4x9+7x1)
=(36 68 43)
