What is the volume of a sphere with the radius of 2 cm?

Answers

V=43πr3=43·π·
3≈33.51032 =33.51 is the answer
Short Answer: 33.5cm3. 

Longer Answer: The formula for volume of a sphere is ( 4 * pi * radius^3) / 3. So, when the radius is 2cm, then it would be ( 4 * 3.14 * 2^3) / 3. We have to do the exponents first, so 2 ^ 3 is 2 * 2 * 2 = 8. Then, we solve the rest of the expressions within the bracket, which will give us ( 100.48 ) / 3, and that equals 33.5

What is the measure of each exterior angle of a decagon?

Answers

The sum of all of the exterior angles of any regular polygon is 360  (I'm assuming by decagon you mean a regular dodecagon).

Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.

360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.

Point-slope form to slope-intercept form

Answers

y=mx+b
y-y1=m(x-x1)

They are different, and the conversion depends on what you need.

What you need:
y-y1=m(x-x1)
y-y1=mx-mx1 (distribute the m)
y=mx-mx1+y1 (move the y1)
y=mx+b (combine mx1 and y1)

Simplify the expression

x^2 + 3x - 28/ x^2 - 7x + 12

Show your work.

Answers

Answer:

(x^4 + -4 x^3 + 12 x^2 - 28)/x^2

Step-by-step explanation:

Simplify the following:

x^2 + 3 x - 7 x + 12 - 28/x^2

Put each term in x^2 + 3 x - 7 x + 12 - 28/x^2 over the common denominator x^2: x^2 + 3 x - 7 x + 12 - 28/x^2 = x^4/x^2 + (3 x^3)/x^2 - (7 x^3)/x^2 + (12 x^2)/x^2 - 28/x^2:

x^4/x^2 + (3 x^3)/x^2 - (7 x^3)/x^2 + (12 x^2)/x^2 - 28/x^2

x^4/x^2 + (3 x^3)/x^2 - (7 x^3)/x^2 + (12 x^2)/x^2 - 28/x^2 = (x^4 + 3 x^3 - 7 x^3 + 12 x^2 - 28)/x^2:

(x^4 + 3 x^3 - 7 x^3 + 12 x^2 - 28)/x^2

Grouping like terms, x^4 + 3 x^3 - 7 x^3 + 12 x^2 - 28 = x^4 + (3 x^3 - 7 x^3) + 12 x^2 - 28:

(x^4 + (3 x^3 - 7 x^3) + 12 x^2 - 28)/x^2

3 x^3 - 7 x^3 = -4 x^3:

Answer:  (x^4 + -4 x^3 + 12 x^2 - 28)/x^2

If x > y and y > z, then x > z. This describes which ordinal scale preference? A. Asymmetry B. Transitivity C. Negative transitivity D. None of the above

Answer:

Step-by-step explanation:

d

Final answer:

The given statement 'If x > y and y > z, then x > z' describes the concept of transitivity in ordinal scales.

Explanation:

The given statement 'If x > y and y > z, then x > z' describes the concept of transitivity in ordinal scales. Transitivity is the property that allows us to compare elements in a set based on their relationships with other elements. In this case, if x is greater than y and y is greater than z, then we can conclude that x is also greater than z.
