$1000

Step-by-step explanation:

So there is 10,000,000 dollars in the company for the annual employee bonus. There are 10,000 employees in this company. This seems like a simple division problem. So you divide 10,000,000 by 10,000 and you get 1,000. So with that being said each employee should receive $1,000 in total.

The equation 50=36.50+0.10m represent the additional number of messages roboerto can send with a budget of $50 .solve the equation to find the number he has left to send

Answers

Answer :
M = 135

Step by Step Explanation :
See the photo attached :) it’s kinda hard to explain in words but you cancel out the 36.50 by subtracting it on both sides, and then the equation becomes 13.50 = 0.10m. Since we have to get the m by itself, you cancel out the 0.10 by subtracting on both sides, and it leaves you with 135 = m

2. The Perimeter of a square is P. Which equation could be used to find its area (A)?
a. A = P2
b. A = (p/4)^2
c. A = 4P
d. A = (√p)^2

Answers

Answer:

A = (P/4)²

Step-by-step explanation:

Given

Perimeter = P

Required

Determine the area

First, we need to calculate the sides of the square using:

[tex]P = 4L[/tex]

Where L represents the length of the side

Make L the subject

[tex]L = \¼P[/tex]

Area is calculated as thus:

[tex]Area = L\²[/tex]

Substitute ¼P for L

[tex]Area = (\¼P)\²[/tex]

Which represents an even function?

B. y = sin(x)

C. y = tan(x)

D. y = cot(x)

NVM I DID IT

ANSWER: A

Answers

Answer:

A. y=cos(x)

Step-by-step explanation:

I just want the points. im taking the quiz rn.

From the given options, the only even function is the cosine function, so the correct option is A.

Which of the options is an even function?

First, an even function is a function with the property:

f(x) = f(-x)

So these functions are symmetrical across the y-axis.

Is ratter easy to remember that the sin function is actually odd, this means that:

sin(-x) = -sin(x).

Then the tangent function (and the cotangent function) are also odd, because:

tan(x) = sin(x)/cos(x).

In the other hand, for the cosine function we have:

cos(-x) = cos(x)

And as shown in the graph below, it is symmetrical across the y-axis.

Then we conclude that the correct option is A.
