n^2- 5n +4=0 quadratic equation

Answers

Answer:

n = 1, 4

Step-by-step explanation:

Step 1: Write equation

n² - 5n + 4 = 0

Step 2: Solve for n

Factor: (n - 4)(n - 1) = 0

Find roots: n = 1, 4

Step 3: Check

Plug in n to verify if it's a solution.

1² - 5(1) + 4 = 0

1 - 5 + 4 = 0

-4 + 4 = 0

0 = 0

4² - 5(4) + 4 = 0

16 - 20 + 4 = 0

-4 + 4 = 0

0 = 0

If you solve by factoring this would be the process of it
Step 1: Factor left side of the the equation
(n-1)(n-4)=0
Step 2: set factors equal 0
n-1=0 or n-4=0
then you would solve both like a regular equation
n=1 or n=4 would be the answers

month membership at Workout Nation costs $630. A registration fee of
$150 is paid up front, and the rest is paid monthly. How much do new
members pay each month?
150x + 12 = 630
150x + 12x = 630
150 + 12x = 630
630x + 12 = 150

Answers

Answer:

150+12x=630

Step-by-step explanation:

The x represents the amount of months and it is multiplied by 12 because each month costs 12$. 150 have to be paid up front and this added to the monthly fee is equal to 630$

Problem How many unique ways are there to arrange the letters in the
word CHRISTMAS?*
362,880
45,255
1
55,698

Answers

Answer:

There are 181,440 ways.

Step-by-step explanation:

Given the word CHRISTMAS

In the word "Christmas" there are 9 letters.

Also take note, the letter "s" is repeated twice.

Hence, the number of ways is given by; no of ways = n!/m!

Where, n = 9, m = 2

no of ways = 9 *8*7*6*5*4*2*1/2*1

no of ways = 9*8*7*6*5*4*3

no of ways = 181,440.

Therefore, the number of unique ways that the letters in the word can be arranged is 181,440.

Simplify i^41 (please help me)

Answers

Answer:

i

Step-by-step explanation:

Answer:  Choice A) i

====================================================

Explanation:

Let's look at the pattern of powers of i

i^0 = 1i^1 = ii^2 = (sqrt(-1))^2 -1i^3 = i*i^2 = i*(-1) = -ii^4 = (i^2)^2 = (-1)^2 = 1

We loop back to 1, and the process starts all over again. The cycle is 4 units long. Ie, the pattern repeats every 4 terms.

What this means is that we can use remainders to quickly figure out something like i^41 without having to use a calculator or tons of paper.

Dividing 41/4 leads to a quotient of 10 and a remainder of 1. We only care about the remainder. The remainder 1 means i^41 = i^1 = i

Note how 41 and 1 lead to the same remainder when we divide by 4.

how do you find a slope from a table??

Answers

Answer:

Pick any point that has x and y together.

For example,   3               4

                         2                7

                         1                 6

Here the two points which you will be picking is either 3 and 4, or 2 and 7 or 1 and 6.

Once you pick, use the formula: rise/run (which means y/x)

Using the same example above, let's just say that you picked 1 and 6. (remember the first column always represents x values whereas the second column always represent y values). You get the slope by 6/1 = 6.
