if 5 is a root of the quadratic equation x²+4x-45=0 find the other root of the equation

Answers

Answer 1

Answer:

-9

Step-by-step explanation:

x² + 4x - 45

x² + (9x - 5x) - 45

x² + 9x - 5x - 45

x(x + 9) - 5(x + 9)

(x + 9)(x - 5)

x + 9 = 0

x = -9

Answer 2

Answer: -9

Step-by-step explanation:

If 5 is a root of the quadric equation, then

x²+4x-45=0

x²-5x+9x-45=0

x(x-5)+9(x-5)=0

(x-5)(x+9)=0

The other root is -9

Find the mean, median, mode, and range of the data set.
9, 3, 15, 7, 2, 4, 3
If necessary, round your answers to the nearest tenth.

Answers

Answer:

Step-by-step explanation:

Mean = Sum of data ÷ number of data set

         [tex]=\dfrac{9+3+15+7+2+4+3}{7}\\\\=\dfrac{43}{7}\\\\= 6.14\\\\= 6.1[/tex]

Middle term is the median of the data set

Median  = 4th term = 4

Mode:

Mode is the data whose is frequency is more.

If Kyle earns $12.50 per hour, how many hours did he work if he earned a total of $400. Set up an equation and solve. Let x = hours.​

Answers

Answer:

32.

Step-by-step explanation:

Here is the equation I used. (x = hours)

$400 = $12.50x

To find how many hours he needs to work, divide both sides by 12.50 to get x by itself.

400/12.50 = 12.50x/12.50

Which equals:

32 = x

Let x = hours.
We have: 12.5 • x = 400
-> x= 400 / 12.5 = 32
So he has been work for 32 hours

Since the card has $0 minimum payments for the first 4 years it is active, Emma wonders how much it will cost her if she
doesn't pay off the $300 balance until after college. How much will she owe in 4 years?
Type the correct response in the box. Use numerals instead of words. Round your answer to the nearest dollar.
In 4 years, Emma will owe about $

Answers

Answer:

$544.61

Step-by-step explanation:

Edmentum

In 4 years, Emma will owe about $544.61 to the credit card company.

The model for Emma's debt in 4 years is given as:

FV = P(1+r/n)^nt,

where:

P = principal ($300)

r = the interest rate (15%)

t = the time in years (4 years)

n = the number of times the interest is compounded per year (12)

However, we can solve the problem with an online financial calculator as follows:

Data and Calculations:

N (# of periods) = 48 (4 x 12 months)

I/Y (Interest per year) = 15%

PV (Present Value) = $300

PMT (Periodic Payment) = $0

P/Y (# of periods per year) = 12

C/Y (# of times interest compound per year) = 12

Results:

FV = $544.61

Total Interest = $244.61

Complete Question:

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the terms of her credit card:

It has a 15% annual interest rate.The interest is compounded monthly.The card has $0 minimum payments for the first four years it is active.

Thus, in 4 years, Emma will owe $544.61 to the credit card company.
