To find the distance between two points (1,4) and (-2,3) using the distance formula, perform the relevant calculations and steps.
Explanation:To find the distance between two points using the distance formula, you can follow these steps:
Identify the coordinates of the two points. In this case, the coordinates are (1,4) and (-2,3).Plug the values of the coordinates into the distance formula: D = (√((x2 - x1)^2 + (y2 - y1)^2)).Calculate the difference between the x-coordinates and the y-coordinates separately. For this example, (x2 - x1) = (-2 - 1) = -3, and (y2 - y1) = (3 - 4) = -1.Square the differences calculated in the previous step: (-3)^2 = 9 and (-1)^2 = 1.Add the squared differences together: 9 + 1 = 10.Take the square root of the sum to find the distance: √10 ≈ 3.16.So, the distance between the points (1,4) and (-2,3) is approximately 3.16 units.

3.) You are paid $8.25/hour. You work 35 hours/week for 3 weeks. Your involuntary deductions are FICA (7.65%), federal withholding (13%), and state withholding (9%). How much is your realized income?
A 203.13
B 866.25
C 288.75
D 609.39
Answer:
1.) [B]
2.) [C]
(3.) [D]
Step-by-step explanation:
1.) Initial amount = $3168
Annual percentage rate = 12.75
per month percentage rate = 1.06%
Interest after 3 months = P*R*T/100
= 3168*1.06*3/100
= 100.74 (aprox)
Balance after 3 months = 3168-100.74
= $3270.06 (aprox) (B.)
2.) Gross pay = $2759
Total interest rate = 7.65%+12%+7% = 26.65%
interest amount= 26.65% *2759 =$728.24 (aprox)
Housing and fixing expenses= $728.54 (C.)
3.) 1 hour = $8.25
1 week= 35 hours
3 weeks = 35*3 hours = 105 hours
Total income= 105 hours = $8.25*105= $866.25
Total interest to be deducted = 7.65+13+9 = 29.65 %
Income after deducting interest = $866.25-256.843 = $609.407
(D.)
The answers are:
1) C - $728.54
2) D - $609.39
3) B - $3,270.06

Step-by-step explanation:
To find first r and then r square for the data

How many centimeters are in 7 feet, given that 1 inch = 2.5 centimeters?
Answer:
210 cm
Step-by-step explanation:
We need to convert 7 ft to cm
We know that 1 ft = 12 inches
7 ft * 12 inches/1 ft = 84 inches
We know that 1 inch = 2.5 cm
( 1 inch is really 2.54 cm but you question says 2.5 cm)
84 inches * 2.5 cm/1 inch = 210 cm

A rectangle has an area (x2-17x+72) square units.Since the area of a rectangle is determined using the formula, A= lw, what could be the length and width of the rectangle
Answer:
length: 9
width: 8
Step-by-step explanation:
you would need to factorise the equation in order to work out the length and width of the rectangle
so to factorise x^2 -17x +72, you will need to numbers that multiply to make 72 and add to make -17
the numbers are -9 and -8
so the factorised equation is (x-9)(x-8)
if you equate it to 0 you get 9 and 8 as values for x
since the length is longer than the width
the length is 9 and the width is 8

-46 times a number minus 19 is equal to 86 less the number
Answer:
-46 * x - 19 = -86
Step-by-step explanation:
this a word problem!
lets break it down
-46 times a number
this will be -46 * x
minus 19 is equal to 86 less the number
-46 * x - 19 = -86
To solve the equation "-46 times a number minus 19 is equal to 86 less the number", we can simplify the equation by combining like terms and isolating x. The solution is x = -105/45 or approximately -2.33.
Explanation:To solve the equation -46 times a number minus 19 is equal to 86 less the number, we can first simplify the equation. Let's call the number x. So, -46x - 19 = 86 - x. We can solve for x by combining like terms and isolating x on one side of the equation. Adding x to both sides gives -45x - 19 = 86. Then, adding 19 to both sides gives -45x = 105. Finally, dividing both sides by -45 gives x = -105/45, which simplifies to x = -7/3 or approximately -2.33.

Elise took out a payday loan for $500 due in 2 weeks that charges an $80 fee. What is the periodic interest rate of the loan?
The periodic interest rate of Elise's payday loan is calculated by dividing the $80 fee by the $500 borrowed, resulting in a rate of 16% for the 2-week period.
To calculate the periodic interest rate of Elise's payday loan, we need to consider the fee charged as the interest for the period of the loan, since the loan is due in 2 weeks, which is a half-month period. Elise is being charged an $80 fee on a $500 loan, and this fee represents the interest for the loan's term.
Therefore, we can calculate the periodic interest rate by dividing the interest by the principal and the number of periods.
Here's the calculation:
Interest (Fee) = $80
Principal (Amount borrowed) = $500
Periodic interest rate = Interest / Principal
Periodic interest rate = $80 / $500 = 0.16 or 16%
Since the period is 2 weeks, we could express this interest rate on a monthly basis if needed by scaling the bi-weekly rate to a monthly rate. However, the loan terms only mention a 2-week period, so the periodic interest rate for the loan's duration is 16%.

The grade that a student scores on her math test is inversely proportional to the number of hours a week that she plays video games. She scores a 73.6 on a test when she plays 10 hours of video games per week. If this relationship continues at the same rate, what score can she expect on her math test if she plays video games for only 8 hours a week?
Answer:
She would make a 78.88% on a test if she played video games for only 8 hours a week.
Step-by-step explanation:
10 hours of video games=73.6% on a test.
8 hours of video games=x% on a test.
A proportion just doesn’t work out for this problem, so here’s what I did.
100-73.6=26.4
26.4 times .8 =21.12
100-21.12 equals 78.88
If you wanted to know what she would make on her test if she played video games for 6, 4, or 2 hours a week, you could do this.
78.88-73.6=5.28
There are increments of -5.28% for every 2 hours of video game play.
As you keep adding, here are the results.
6- 84.16%
4- 89.44%
2- 94.72%
0- 100%
After 18 hours of gameplay in a week, you would get 4.96% on a test, and then a 0 on not even completing the 19th hour.
