Find CE.

Answer: 5 or -5

Step-by-step explanation:

Since a^2+b^2=c^2 is the Pythagorean theorem, you need to plug in a=3 and b=4 into the equation. 3^2+4^2=c^2. Simplify the left side of the equation first. 3^2 is 9 and 4^2 is 16. 9+16=25. So, 25=c^2. Take the root of this and the square root of 25 is -5 or 5 interchangeably.

When a number has an exponent of 0, it means that the number is being multiplied by itself 0 times. In other words, it is multiplied by 1.

To determine this:

In the case of 3 with an exponent of 0, it would be represented as 3^0. To calculate the value, we would take 3 and multiply it by 0 times.

3 x 1 = 3

So, 3 with an exponent of 0 is equal to 3.

It is important to note that any number with an exponent of 0 will always equal 1, except for 0 which will always be 0. This is because any number multiplied by 1 is itself, and 0 multiplied by any number is always 0.

Answer:

5x + y = 34

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

x - 5y = 8 ( subtract x from both sides )

- 5y = - x + 8 ( divide through by - 5 )

y = [tex]\frac{1}{5}[/tex] x - [tex]\frac{8}{5}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{1}{5}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{5} }[/tex] = - 5 , then

y = - 5x + c ← is the partial equation

to find c substitute (5, 9 ) into the partial equation

9 = - 25 + c ⇒ c = 9 + 25 = 34

y = - 5x + 34 ← equation of perpendicular line in slope- intercept form

add 5x to both sides

5x + y = 34 ← equation in standard form

The 4:5 ratio in terms of pixels is nothing but the measure of 1080×1350 pixels in an image of the video.

A colon separates two numbers that represent the width-to-height proportion of an image or video. This proportion or ratio is referred to as the aspect ratio. In terms of height and width, it shows how wide the size is. It makes sure the videos or images are presented without stretching or resolution loss.

The resolution in pixels for the aspect ratio 4x5 or 4:5 is 864 x 1080 or 1080 x 1350 pixels. This establishes how many pixels are present in an image's or video's width and height. The most popular pixel ratio is this one.

The slope of line y  = 10 is zero.

We know that the slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate.

It describes the steepness of a line.

The slope of x - axis.

m = 0

As for x-axis the change in y-coordinate is zero.

So, by definition of slope,

m = 0/(change in x coordinate)

m = 0

We know that the slopes of parallel lines are equal.

A line y = 10 is parallel to x-axis

So, the slope of line y = 10 is zero.

On solving the provided question we can say that the value of multiplication is x^34.

A math problem is a problem or question that requires the application of mathematical concepts and skills to solve.It is an extension of repeated addition. The operation is symbolized by the multiplication sign "x" or an asterisk (*), a dot (•) or the letter "m" . .

For example, if we multiply 4 and 5, the product will be 20 (4x5 = 20).

In addition, multiplication can also be represented using the distributive property, which states that for any three numbers a, b and c, a(b+c) = ab + ac.

In Multiplication, order of numbers doesn't matter, meaning a x b = b x a.

It's also commutative, meaning the order of numbers doesn't change the result.

Multiplication is the foundation for many other mathematical concepts, including algebra and geometry. It's an essential operation in many fields such as science, engineering, and finance.

Let sales units of Pecan = p and sales units of chocolate = c

Equation 1: 8p + 6c = 182

Equation 2: 7P + 12C = 274

Multiply Equation 1 by 2:

Equation 3: 16p + 12c = 364

Subtract Equation 2 from Equation 3:

16p + 12c = 364

-

7P + 12C = 274

9p = 90

p = 10

= $10

Substitute, p = 10, in Equation 1:
