Answer:

62.8 units

Step-by-step explanation:

The formula for a cylinder πr²h. R being the radius and h being the height.

Therefore, plug in the numbers and solve.

π(2)²(5) = 20π = 62.8 units

Divide -3x^3-2x^2-x-2 by x-2

Rasek [7]

Let's do this by Briot-Ruffini

First: Find the monomial root

x - 2 = 0

x = 2

Second: Allign this root with all the other coeficients from equation

Equation = -3x³ - 2x² - x - 2

Coeficients = -3, -2, -1, -2

2 | -3 -2 -1 -2

Copy the first coeficient

2 | -3 -2 -1 -2

-3

Multiply him by the root and sum with the next coeficient

2.(-3) = -6

-6 + (-2) = -8

2 | -3 -2 -1 -2

-3 -8

Do the same

2.(-8) = -16

-16 + (-1) = -17

2 | -3 -2 -1 -2

-3 -8 -17

The same,

2.(-17) = -34

-34 + (-2) = -36

2 | -3 -2 -1 -2

-3 -8 -17 -36

Now you just need to put the "x" after all these numbers with one exponent less, see

2 | -3x³ - 2x² - 1x - 2

-3x² - 8x - 17 -36

You may be asking what exponent -36 should be, and I say:

None or the monomial. He's like the rest of this division, so you can say:

(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 with rest -36 or you can say:

(-3x³ - 2x² - x - 2)/(x - 2) = -3x² - 8x - 17 - 36/(x - 2)

Just divide the rest by the monomial.

2. The area of the rectangle shown is 375 square centimeters,

polet [3.4K]

Answer:

Step-by-step explanation:

Area is l x h. If that's the case then we need to do the oposite of multiplication to get the answer we need. Divide 375cm an 25cm to get your answer.

Original Equation:

A = l x h

New Equation:

A/l = h

The figure below shows two parallel lines intersected by a third line. What is the value of x

lisabon 2012 [21]

Answer:

$x = 20$

Step-by-step explanation:

The two angles given in the diagram are alternate interior angles. Alternate interior angles are congruent. Therefore:

(4x)° = (x + 60)°

Use the equation to solve for the value of x

$4x = x + 60$

Subtract x from both sides

$4x - x = x + 60 - x$

$3x = 60$

Divide both sides by 3

$\frac{3x}{3} = \frac{60}{3}$

$x = 20$

What is the LCD of 1/6 and 5/12 and 11/18

Oksi-84 [34.3K]

Finding the Lowest Common Denominator of: $\frac{1}{6} ; \frac{5}{12} ; \frac{11}{18} 
$

Here's to find out how it was our LCD: $\frac{1}{6} = \frac{6}{36}$
$\frac{5}{12} = \frac{15}{36}$
$\frac{11}{16} = \frac{22}{36}$
To find the fraction on the right side we had to multiply (and somewhat divide to get the answer)

So, therefore the Lowest Common Denominator of this question would most likely be: $36$

Good Luck!
