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

Answer:

5 and 1/4 hours or 5 hours and 15 minutes

Step-by-step explanation:

She played her flute 3/4 hours every day for 7 days, so to find the total number of hours we can multiply 3/4 by 7 to get 21/4.  This is equal to 5 and 1/4 hours, or 5 hours and 15 minutes.

Answer:  5.25 hrs

Step-by-step explanation:  3/4 of an hour is 45 min.  45 min x 7 days is 315 min which is 5 hours and 15 min or 5.25 hrs

We have that the Polynomial is named as a  Quintic polynomial

From the Question we are told that

Polynomial=[tex]X^4-3x^2+7x^5[/tex]

We note that the Polynomial is of degree 5 as its highest Sum of its exponent is a

Quintic polynomial

Therefore

The Polynomial is named as a  Quintic polynomial

In conclusion

For every Polynomial at degree five that is a greatest power of 5 (e^5) the accurate name for this polynomial is called a Quintic Polynomial

Answer:

We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.

I believe that it’s the last one because it makes the most sence but then again i could be wrong

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]

Median:

Arrange the data in ascending order:

2 , 3 , 3 , 4 , 7 , 9 , 15

Middle term is the median of the data set

Median  = 4th term = 4

Mode:

Mode is the data whose is frequency is more.

So, mode = 3

Range = Maximum - minimum

           = 15 - 2

           = 13

We have with a  study the diagram of the diagram below and the explanations that follows the correct answers are

Generally

1)

OP is a segment bisector.

NO

OP is not a segment bisector because it those not divide segment LKMN in to two equal parts.

2)

OP is a perpendicular bisector.

NO

OP is not a perpendicular bisector because a perpendicular bisector is a bisector that cuts a segment into two equal parts and create an angle to the normal

3)

OP is an angle bisector

NO.

Because OP those not divide any angles into two equal parts

4)

O is the vertex of a pair of congruent angles in the diagram.

YES

Because O lines in between two angles of the same degree()

5)

O is the vertex of a right angle.

NO

Because O those not exist at a right angle

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:

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:

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

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:

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