How do you find volume and surface area?

The volume for a rectangular pyramid is (LWH)/3, meaning to multiply the length by the width by the height and then divide the product by 3.
Since I've explained how to solve this, let's start solving!
Our length and width are 2, and our height is 3.
Multiply our length by our width by our height.
3 x 2 x 2 = 6 x 2 = 12.
Remember when finding volume, we're dealing with a 3rd dimension, so our unit of measure is ^3.
Your volume is 12in^3.
The surface area for a rectangular pyramid is 16.65 in^2. I hope this helps!

Write an equation of the line that passes through(2,7) and (0,-5)
SVETLANKA909090 [29]

Answer:

-6x + y = -5\:or\:y = 6x - 5

Step-by-step explanation:

First, find the <em>rate of </em><em>change</em><em> </em>[<em>slope</em>]:

\frac{-y_1 + y_2}{-x_1 + x_2} = m

\frac{-7 - 5}{-2 ± 0} = \frac{-12}{-2} = 6

Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope</em><em> </em><em>Formula</em><em> </em>because you get it done much swiftly. In this case, we have a y-intercept of [0, -5], so this is a giveaway. It does not matter which ordered pair you choose:

-5 = b \\ \\ y = 6x - 5

If you want it in <em>Standard</em><em> </em><em>Form</em>:

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

_______________________________________________

7 = 6[2] + b

12

-5 = b \\ \\ y = 6x - 5

y = 6x - 5

- 6x - 6x

_________

-6x + y = -5

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

I am joyous to assist you anytime.

Determine whether or not the given differential equation is separable, that is, whether it can be expressed in the form p(y) dy
Flura [38]

Answer:

Yes , it is separable

Step-by-step explanation:

We are given that DE

\frac{dy}{dx}-2y=16+3xy+24x

We have to find the the given DE is separable or not.

\frac{dy}{dx}-2y=16x+3xy+24x

\frac{dy}{dx}=16+3xy+24x+2y

\frac{dy}{dx}=16+24x+3xy+2y=8(2+3x)+y(3x+2)

\frac{dy}{dx}=(2+3x)(8+y)

\frac{dy}{8+y}=(2+3x)dx

When the DE is separable then it can be written as

p(y)dy=q(x)dx

Given DE is in Separable form.Therefore, it is separable.
