Find the number that should be added to the expression to make a perfect square k^2+11k
Alja [10]
<span>k^2+11k has 11 as the coefficient of the first power of the variable (k).

To complete the square:

Take HALF of this coefficient.  In other words, take HALF of 11, obtaining 11/2.

Square this (11/2):  (121/4)

Add this 121/4   to  </span><span>k^2+11k 

Result:     </span><span>k^2+11k + 121/4

This is a perfect square:    </span>k^2+11k + 121/4  = (k + 11/2)^2

Answer:  The number to be added to k^2 + 11k to make it a perfect square is  (121/4).

The mathematical model C (x) = 200x + 10,000 represents the cost in dollars a company incurs when
Reil [10]

We have been given a function C(x)=200x+10,000 represents the cost in dollars a company incurs when  producing x items during a month. We are asked to find the cost to produce 50 items.

To find the cost to produce 50 items, we will substitute x=50 in our given function as:

C(50)=200(50)+10,000

C(50)=10,000+10,000

C(50)=20,000

Therefore, it will cost $20,000 to produce 50 items.

Attachment Below- help would be appreciated! :)

Answer:

A, B, C, E, and F

To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.

From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.

Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.

Hope this helped!
