What is the volume of a rectangular prism with length 6 feet, width 4 feet, and height 8 feet

lana66690 [7]

Answer:

$\boxed{\sf{192ft\ ^2}}$

Step-by-step explanation:

To find:

The volume of a rectangular prism.

Given:

Use the formula of a rectangular prism.

Note:

$\Longrightarrow: \sf{V=L*W*H}$

Solutions:

L stands for length.
W stands for width.
H stands for height.

L= 6
W= 4
H= 8

Multiply the numbers from left to right.

$\Longrightarrow:\sf{6*4*8=\boxed{\sf{192}}$

$\Longrightarrow: \boxed{\sf{192ft \ ^2}}$

Therefore, the final answer is 192ft².

I hope this helps, let me know if you have any questions.

Good luck with your assignment!

VladimirAG [237]

Answer:

Step-by-step explanation:

(x + p)(x + 9) =

= x^2 + 9x + px + 9p

= x^2 + (9 + p)x + 9p

The constant term is 9p.

Use implicit differentiation to find an equation of the tangent line to the curve at the given point. x2 + 6xy + 12y2 = 28, (2,

navik [9.2K]

Answer:

The equation of the tangent line is $y = -\frac{5}{18}\cdot x +\frac{14}{9}$ .

Step-by-step explanation:

Firstly, we obtain the equation for the slope of the tangent line by implicit differentiation:

$2\cdot x + 6\cdot y + 6\cdot x \cdot y' + 24\cdot y \cdot y' = 0$

$2\cdot (x + 3\cdot y) + 6\cdot (x + 4\cdot y) \cdot y' = 0$

$6\cdot (x + 4\cdot y) \cdot y' = -2\cdot (x+3\cdot y)$

$y' = -\frac{1}{3}\cdot \left(\frac{x + 3\cdot y}{x + 4\cdot y} \right)$ (1)

If we know that $(x,y) = (2, 1)$ , then the slope of the tangent line is:

$y' = -\frac{1}{3}\cdot \left(\frac{2+3\cdot 1}{2 + 4\cdot 1} \right)$

$y' =-\frac{5}{18}$

By definition of tangent line, we determine the intercept of the line ( $b$ ):

$y = m\cdot x + b$

$b = y - m\cdot x$ (2)

If we know that $(x,y) = (2,1)$ and $m = -\frac{5}{18}$ , then the intercept of the tangent line is:

$b = 1 - \left(-\frac{5}{18} \right)\cdot (2)$

$b = \frac{14}{9}$

The equation of the tangent line is $y = -\frac{5}{18}\cdot x +\frac{14}{9}$ .
