Richie is solving the equation x^2 – 12x = 28 by completing the square. What number should he add toboth sides of the equation to complete the square? Pleaseee Help

Answers

Answer 1
Answer:

Answer:

Richie should add the number 36 to both sides.

Step-by-step explanation:

To complete the square, you need to divide b by 2, square it, then add it to both sides. In this case, you'd do this:

12/2=6

6^2=36

if you have
3x+8y=8
subtract 3x from both sides
8y=3x+8
divide boh tsides by 8
y=8/3x+1
y intercpt=1
slope=8/3
the slope-intercept form should be( y=mx+b )

Solve for u in terms of q, r, s, and t.
su= -rqt

Answers

The expression of u in terms of q, r, s, and t is u = -rqt/s.

We have,

To solve for u in terms of q, r, s, and t in the expression su = -rqt, you can isolate u by dividing both sides of the equation by s:

su = -rqt

This involves applying the principles of algebraic manipulation and equation solving to rearrange the equation and express "u" in a desired form.

Divide both sides by s:

u = -rqt / s

So, the solution for u in terms of q, r, s, and t is:

u = -rqt / s

Thus,

The expression of u in terms of q, r, s, and t is u = -rqt/s.

Larry has taken out a loan for college. He started paying off the loan with a first payment of $150. Each month he pays, he wants to pay back 1.3 times as the amount he paid the month before. Explain to Larry how to represent his first 15 payments in sigma notation. Then explain how to find the sum of his first 15 payments, using complete sentences. Explain why this series is convergent or divergent.

Answers

  14
   Σ  [(1.3^n) * (150)]
n = 0

Using the sigma notation to find the sum of his first 15 payments, each of the possible values of n (from 0 to 14) are substituted into the equation. After which, each of the results are then added to each other. Also, the problem states that only the first 15 payments are to be included in the notation. This shows that the series is limited and is finite. Therefore, it is a convergent series.

There once was afarmer who, as part of his route to town, used a rickety old boat to cross a wide river. He took his dog and went to town one day to buy corn. However, not only did he buy some corn, but he also bought a goose that he intended to take home and use to start raising geese. (The farmer was no fool, he already had another goose.) He also knew, however, that his boat was not reliable. It could only handle himself (to row) and one of the other three things he had with him. He feared that if left alone, the dog the corn. How could he get himself and everything else across the river?
