Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5. Enter your answer into
ANEK [815]

Answer:

-3/5x + y = - 26/5

Step-by-step explanation:

First, I put everything in slope-intercept form, just because it's more simple for me.

y = 3/5x + b

Since we don't have b, we can use the coordinate they give us to solve for it.

-4 = 3/5 (2) + b

-26/5 = b

y = 3/5x - 26/5

Now, we can move the variables around to fit the form:

Ax + By = C

-3/5x + y = - 26/5

I hope this helped!

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to
stich3 [128]

The volume of the box is maximized when a 6 x 6 inch or 10 x 10 inch square is cut from the corners of the rectangular sheet.

Volume of rectangle:

The volume of an object is the amount of space occupied by the object or shape, which is in three-dimensional space. It is usually measured in terms of cubic units.

The formula for Volume of the rectangle is

V = l x b x h

where

l represents the length

b represents the breadth

h represents the height.

Given,

A rectangular sheet of tin measures 20 inches by 12 inches. suppose you cut a square out of each corner and fold up the sides to make an open-topped box.

Here we need to find the volume of the box is maximized when a square is cut from the corners of the rectangular sheet.

Here we have the following values:

h = x

l = 20 - 2x

b = 12 - 2x.

Here we have to subtract two times of x value because in the question they said that we have to cut a square from it.

Apply the values on the volume formula then we get,

=> V = (20 - 2x) x (12 - 2x) x (x)

=> V = [240 - 40x - 24x + 4x²] x (x)

=> V = [240x - 64x² + 4x³]

Now differentiate:

=> V' =  240 - 64x + 4x²

Simplify and order the equation,

Then we get,

=> V' = x² - 16x + 60

When we factorize the equation then we get,

=> V' = x² - 6x - 10x + 60

Take the common term out of it,

=> V' = x (x-6) -10(x -6)

Therefore, the value of x is, either 6 or 10.

Now you need to look at your solutions.

At x=6, the volume is,

=> V = (20 - 2(6)) x (12 - 2(6)) x (6)

=> V = (20 - 12) x (12 - 12) x 6

=> V = 8  x 0 x 6

=> V = 0

our corner squares devour the entire piece of cardboard and you are left with zero volume; so that solution is a minimum.

Now at the value of x = 10,

The volume is

=> V = (20 - 2(10) x (12 - 2(10)) x (10)

=> V = (20 - 20) x (12 - 20) x 10

=> V = 0 x (-8) x 10

=> V = 0

So, in both cases we have 0 as minimum volume. So, we can take any one of the value to get the maximum out of it.

Determine if the sides form a right triangle.
Law Incorporation [45]

Answer:

Yes, it's a right-angle triangle

Step-by-step explanation:

3 root 2 is 4.24

3 root 3 is 5.2

3 root 5 is 6.71

3 root 5 is the longest side, so must be the hypotenuse.

a^2 + b^2 = c^2

(3 root 3)^2 + (3 root 2)^2 = c^2

45 = c^2

Square root both sides

C = root 45

( simplified to C= 3 root 5)

Thus, it is a right-angle triangle.

(Root means a square root)

Hope this helps!
