Use the distance formula to calculate XY, then equate to 10
d = [tex]\sqrt{x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = X(a -5, - 2a) and (x₂, y₂ ) = Y(a + 1, 2a)
XY = [tex]\sqrt{(a +1-(a-5))^2+(2a-(2a))^2\\}[/tex]
= [tex]\sqrt{(a+1-a+5)^2+(4a)^2}[/tex]
= [tex]\sqrt{6^2+16a^2}[/tex] , then
[tex]\sqrt{36+16a^2}[/tex] = 10 ( square both sides )
36 + 16a² = 100 ( subtract 36 from both sides )
16a² = 64 ( divide both sides by 16 )
a² = 4 ( take the square root of both sides )
a = ± [tex]\sqrt{4}[/tex] = ± 2
Write the equation in the form y = mx + b, of any line that is perpendicular to the line y = 5x + 4.
Answer:
y = -1/5x - 2
Step-by-step explanation:
All you need is a perpendicular slope and any y-intercept.
Perpendicular slope is a negative reciprocal so:
5 → -1/5
y-intercept doesn't matter so:
y = -1/5x - 2
Answer:
y= -1/5x +4
Step-by-step explanation:
To find a perpendicular line, you need the negative reciprocal of the slope, in this case it is 5 and -1/5.

Hailey invested $2,000 in an account paying an interest rate of 2\tfrac{3}{8}2 8 3 % compounded continuously. Sophie invested $2,000 in an account paying an interest rate of 2\tfrac{7}{8}2 8 7 % compounded daily. To the nearest hundredth of a year, how much longer would it take for Hailey's money to double than for Sophie's money to double?
Answer:
5.08 years
Step-by-step explanation:
We are to solve for time using compound interest formulas
For Hailey
Principal = $200
Amount = Double of Principal = $4000
Rate = 2 3/8% = 2.375.
Time = ?
Hence,
First, convert R as a percent to r as a decimal
r = R/100
r = 2.375/100
r = 0.02375 per year,
Then, solve the equation for t
t = ln(A/P) / r
t = ln(4,000.00/2,000.00) / 0.02375
t = 29.185 years
≈ 29.19 years
For Sophie
Principal = $200
Amount = Double of Principal = $4000
Rate = 2 7/8% = 2.875
Time = ?
First, convert R as a percent to r as a decimal
r = R/100
r = 2.875/100
r = 0.02875 per year,
Then, solve the equation for t
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 0.02875/365)] )
t = ln(4,000.00/2,000.00) / ( 365 × [ln(1 + 7.8767E-5)] )
t = 24.11 years
How much longer would it take for Hailey's money to double than for Sophie's money to double?
For Hailey it takes 29.19 years
For Sophie it takes 24.11 years
We find the difference
= 29.19 - 24.11
= 5.08 years
Therefore, it would take 5.08 years for Hailey's money to double than Sophie

Answer:
n = -7
Step-by-step explanation:
n - 7/4 = 35/12 + 5/3n
subtract n from both sides of the equation:
-7/4 = 35/12 + 2/3n
convert -7/4 to -21/12:
-21/12 = 35/12 + 2/3n
add 21/12 to both sides:
0 = 56/12 + 2/3n
convert 2/3n to 8/12n:
0 = 56/12 + 8/12n
subtract 56/12 from each side:
8/12n = -56/12
multiply both side by 12:
8n = -56
divide both sides by 8:
n = -7

there were 64 basketball games during the NCAA tournament 16 of those games were decided by 3 points or less what percentage of games were decided by 3 points or less
Answer:
25%
Step-by-step explanation:
We can use a proportion to answer this question:
64 represent the 100% of the games
so:
x : 100 = 16 : 64
x = (16*100)/64 = 1600/64 = 25%

Answer:
Option A
Step-by-step explanation:
The unit volume explains it all.
Volumes are measured in units of length cubed. This also is the volume occupied by unit cubes.
By unit cubes, I meant, view the photo above
The volume of an object's says, how many of these cubes will fill that object.
It may not necessarily by a whole number.
So, the answer is Option A

The scale factor from rectangle you UVWX two rectangle STQR is
Answer:
The scale factor is 1/3
Step-by-step explanation:
Compare side length XW with RQ, the side length decreases from 15 to 5, which is a shrinking by a factor of 1/3, since 5 is 1/3 of 15. You can check this by comparing the sides WV with RS, and since 8 is 1/3 of 24, the scale factor is 1/3 going from UVWX to STQR.

5. is C which is 9.
6. is B which is 37.
Step-by-step explanation:
The first on is C. 9 because to find the interquartile range you need to subtract the upper quartile range by the lower quartile range. The upper is 16 and the lower is 7 so you do 16-7 which is 9.
The last question is B. 37 because the lower quartile range is first line in the box plot which is 37.

Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
Answer:
x=-1/5
y=41/5
I am not able to explain to you how I achieved these results, but at least you can try and see if you can solve the equation.
Answer:
No, (2,6) is not a solution to this system of equations.
Explanation:
Okay so lets restate the question:
Is (2, 6) a solution to this system of equations?
y = x + 4
y = 9x + 10
First, you find the x and y intercepts from the equations stated above.
y=x+4
x intercept(s): (-4,0)
y intercept(s): (0,4)
So for the first equation, (2,6) is not a solution.
Now, we find the x and y intercepts for the second equation.
y=9x+10
x intercept(s): (-10/9,0)
y intercept(s): (0,10)
So for the second equation, (2,6) is not a solution.
Both equations do not have (2,6) involved.
And its 24 points not 48 :((((
There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter. To the nearest meter, how many meters are in 396 inches? Enter the answer in the box.
Hello, I Am BrotherEye
Answer:
Multiply total meters by 100 to get total centimeters:
6 meters x 100 = 600 centimeters.
Now divide total centimeters by 2.554 to get total inches:
600 centimeters / 2.54 = 236.22 inches.
Rounded to the nearest inch = 236 inches.
Step-by-step explanation:
*Important!
You multiply the length of the value by 39.37
Meaning that if you have 6 meters you would
Multiply it by 39.37 and get 236.22 inches. Please remember these rules for they will assists you in the future.
