Answer:

396 ft³

Step-by-step explanation:

V = height × base × length

Since this is a prism, we divide it by 2.

V = (8ft × 9ft × 11ft) ÷ 2

= 396 ft³

What is the completely factored form of f(x) = 6x3 – 13x2 – 4x 15? (x 1)(6x2 – 19x 15) (x 1)2(2x – 3) (x 1)(3x – 2)(5x – 3) (x 1
ludmilkaskok [199]

The completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

<h3>How to factor the expression?</h3>

The expression is given as:

f(x) = 6x³ - 13x² - 4x + 15

Expand the expression

f(x) = 6x³ - 19x² + 6x² + 15x - 19x + 15

Rewrite as:

f(x) = 6x³ + 6x² + 15x- 19x²   - 19x + 15

Factorize the equation

f(x) = (x + 1)(6x²- 19x + 15)

Expand (6x² - 19x + 15)

f(x) = (x + 1)(6x² - 10x - 9x + 15)

Factorize the expression

f(x) = (x + 1)(2x - 3)(3x - 5)

Hence, the completely factored form of f(x) = 6x³ - 13x² - 4x + 15 is f(x) = (x + 1)(2x - 3)(3x - 5)

Use the given conditions to write an equation for the line passing through (-8,8) and parallel to the line whose equation is 5x-
Leni [432]

5x - 8y + 104 = 0 is a linear equation passing through (-8 , 8) and parallel to the line whose equation is 5x - 8y - 7 = 0.

First, for two equations of line to be parallel with each other, their slope must be equal.

Transforming the given equation into slope-intercept form, y = mx + b:

5x - 8y - 7 = 0

8y = 5x - 7

y = 5/8 x - 7/8

m = 5/8

Hence, the slope of our equation should also be 5/8.

Using the again the slope intercept form, solve for b.

y = mx + b

where m = 5/8, x = -8 and y = 8

8 = 5/8 (-8) + b

8 = -5 + b

b = 13

With m= 5/8 and y-intercept, b = 13, the equation of our line is

y = mx + b

y = 5/8 x + 13

Multiplying both sides by 8,

8y = 5x + 104

5x - 8y + 104 = 0
