Answer:

1005 in^3

Step-by-step explanation:

Think of this cake as a cylindrical solid of base radius 8 in and height 5 in.

The volume is V = (base area)(height), which here is:

                        V = (pi)*(8 in)^2*(5 in) = 320pi in^3, or approximately 1005 in^3

<h3>What is Complex number?</h3>

A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.

Here, given expression;

    y = √(-9)

    y = √9 X √(-1)

   y = 3√(-1)

   y = 3i

Thus, the expression which is equivalent to √(-9) is 3i.

Answer:

  1. Parallel
  2. Neither parallel nor perpendicular ​
  3. Perpendicular

Step-by-step explanation:

<u>Given line m:</u>

  • y = 4/5x - 3

<u>Relationship of line m with following lines:</u>

1.<u> y = 4/5x + 3</u>

  • Same slope, different y-intercept
  • Parallel

2. <u>y = -4/5x + 3</u>

  • Slope are negative, different y-intercept
  • Neither parallel nor perpendicular ​

3. <u>y = - 5/4x + 3</u>

  • Slopes are negative-reciprocal, different y-intercept
  • Perpendicular

8090 [49]

Answer:

6(x-3)

Step-by-step explanation:

the common number for 6 and 18 is 6 so if you extract that from the expression then it turns to 6(x-3) which cannot be factored further
