Answer 2
Answer:

Final answer:

To simplify √18, we first find the prime factors of 18, then use those factors to rewrite √18 in a simplified form. For 18, which is 2 * 3^2, the square root simplifies to 3√2.

Explanation:

The goal here is to simplify √18. To begin, we find the prime factors of 18. The prime factors of 18 are 2 and 3. Hence 18 can be written as 2 * 3 * 3 or 2 * 32. We substitute this representation into our original expression, √18 becomes √(2 * 32). From our knowledge of square roots, we know that √(a2) can be simplified to 'a'. That is, the square root of the square of a number is the number itself.  Hence, √(32) can be simplified to 3. So we have √(2 * 32) = √2 * 3 = 3√2. So, the simplification of √18 is 3√2.

Micah takes a job with a starting salary of $78,000 for the first year. He earns a 4% increase each year. How much does Micah make over seven years?

Answers

Answer:

Micah make 616066.97 $ over seven years

Step-by-step explanation:

This increase is in the form of a geometric progression.

Micah takes a job with a starting salary of $78,000

First term of GP = $78,000

He earns a 4% increase each year

Common ratio =1+(4)/(100)=1.04

Sum of n terms of GP with first term a and common ratio r.

            s_n=(a(r^n-1))/(r-1)

How much does Micah make over seven years, so wee need to find sum of GP when n = 7.

        s_7=(78000(1.04^7-1))/(1.04-1)=616066.97\$

Micah make 616066.97 $ over seven years

           

So his job has a starting salary of $78,000 and he gets a 4% increase each year. 4% of 78,000 is 3120 since 3120 divided by .04 equals 78,000, and 78,000+3120 = 81120 x 7= 567,840. So every year he can make $81120 and multiply that by 7, Mica would earn $567,840 every 7 years with the 4% increase in his salary every year.

This is linear. Linear is constant but exponential basically multiplys in a interval

Which concept is used to prove that the opposite sides of a parallelogram are congruent? congruent rectangles similar rectangles congruent triangles similar triangles

Answers

The correct answer is:


Congruent triangles.


Explanation:


Consider the top and bottom sides of the parallelogram parallel lines. The diagonal of the parallelogram would be the transversal.


The diagonal splits each opposite angle into two pieces. Using the diagonal as a transversal means we have two pairs of alternate interior angles; this means each pair is congruent. This gives us two congruent angles in two triangles.


The diagonal of the parallelogram is congruent to itself. This gives us two angles and the side between them; this is the angle-side-angle, or ASA, congruence theorem. This proves that the two triangles are congruent.


Since the two triangles are congruent, the corresponding parts of each triangle would be congruent; this means the opposite sides of the parallelogram are congruent.
I think it's congruent triangles

Which of the following represents "the difference between a number and eight is twenty-two"?8 - N = 22
N - 8 = 22
8 - 22N

Answers

Both of the first 8 - N = 22 N - 8 = 22 Represent the difference between a number and 8 is 22 as it is not mentioned that either 8 or the unknown number N is greater so both of the first two represent the difference between a number and 8 is twenty two.

Answer:

The Answer is N - 8 = 22

this is because the question ask the difference of a number and eight is twenty-two, which means a number (N) comes first before the difference ( - ) is  eight (8) is (=) twenty two (22) following this order gives the answer above in bold.

Suppose a triangle has sides 3, 4, and 6. Which of the following must be true? A. The triangle in question is a right triangle. B. The triangle in question is not a right triangle. C. The triangle in question may or may not be a right triangle.

Answers

We can use the Pythagorean theorem:
c² = a² + b²
In this case:
6² = 3² + 4²
36 = 9 + 16
36 = 25  ( not correct )
This is not a right triangle.
