A square has the vertices at (- 2, 6), (6, 1), (1, - 7) , and (- 7, - 2) . At what point do the diagonals of the square intersect?
Answer:
Intersection point is: (-1/2, -1/2)
Step-by-step explanation:
Notice from the attached image of the points on the plane, that opposite vertices are for example:
(-2, 6) and (1, -7), and we know that in a square, the diagonals intersect dividing themselves in equal parts. So what we need to find is the midpoint of the segment that joins (-2, 6) and (1, -7) to find where the diagonals intersect.
We use the formula for the midpoint:
x-midpoint = (x1 + x2) / 2
y-midpoint = (y1 + y2) / 2
In the case of the points (-2, 6) and (1, -7) these become:
x-midpoint = (-2 + 1) /2 = -1/2
y-midpoint = (6 + -7) / 2 = -1/2

Gina and Glen share a 24-ounce bucket of clay. By the end of the week, Gina has used
5/8
of the bucket, and Glen has used
1/4
of the bucket of clay. How many ounces are left in the bucket?
Answer: 3 ounces
Step-by-step explanation:
1/4=2/8
5/8 + 2/8 = 7/8
7/8 = x/24
8x3= 24
7x3=21
24-21=3
Answer:
3 ounces remain
Step-by-step explanation:
5/8 + 1/4 = ?
5/8 + 2/8 = ? (find common denominators)
= 7/8 of the bucket
7/8 = ?/24 (trying to find how many ounces is 7/8 of the bucket)
7/8 = 21/24 (multiple 7 with 3)
24 - 21 = ? (trying to find how many ounces are left)
= 3 ounces

Give your answer as a fraction in its simplest form.
Answer:
1/8
Step-by-step explanation:
Answer:
8/1
Step-by-step explanation:
If we evaluate the expression it will look like:
P = 8*1
if we solve it :
p=(1)(8)
Step 1: Simplify both sides of the equation.
p=8
( 8 is same as 8/1 in fraction )

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y=-3x2 + 197x –
1279
Answer:
$1954
Step-by-step explanation:
Given the profit function expressed as;
y=-3x^2 + 197x – 1279
The profit is at maximum when dy/dx = 0
dy/dx = -6x + 197
0 = -6x+197
6x = 197
x = 197/6
x = 32.83
substitute 32.83 into the modeled function
y=-3x^2 + 197x – 1279
y -3(32.83)²+197(32.83) - 1279
y = -3(1,078.03)+6,467.51 - 1279
y = -3,234.09+6,467.51-1279
y = 1,954.42
hence the maximum amount of profit the company can make, to the nearest dollar is $1954
The formula for continuously compounded interest on a principal investment Pat a given interest rater
over time tin years is given by A = Per? You have deposited $12,000 in an account that pays 4.15%
interest, compounded continuously. How long will it take for your initial investment to grow six times its
original worth? Round your answer to the nearest tenth.
Answer:
43.2 years
Step-by-step explanation:
The formula for continuously compounded interest on a principal investment Pat a given interest rater
over time tin years is given by A = Pe^rt
P = Initial amount compounded = $12000
A = Amount compounded continuously after t years = six times it's original worth
= 6 × $12,000 = $72000
r = Interest rate = 4.15%
t = time in years = ?
Making t the subject of the formula
t = ln(A/P) / r
First, convert R percent to r a decimal
r = R/100
r = 4.15%/100
r = 0.0415 per year,
Then, solve our equation for t
t = ln(A/P) / r
t = ln(72,000.00/12,000.00) / 0.0415
t = 43.175 years
Approximately t = 43.2 years
The time required to get a total amount of $ 72,000.00 from compound interest on a principal of $ 12,000.00 at an interest rate of 4.15% per year and compounded continuously is 43.2years.
The profit of a football club after a takeover is modeled by p(t)=t^3-14t^2+20t+120,where t is the number of years after the take over, in which years was the club making a loss ?
When looking at the following expression, we can tell that it has no rational roots. However, it does have zeros at:
t = -0.45, 2.16, 12.29.
When thinking of the cubic curves you know that p(t) < 0 for 2.16 < t < 12.29. Meaning the team took a loss in years 3-12.

Solve the system by any method.
(3x – 4y = -5
(5x + 8y = -1
Answer:
( x , y ) = ( -1,1/2)
Step-by-step explanation:
Solve the equation for X
[tex]\left \{ {{x=-5/3+4/3y} \atop {5x+8y=-1}} \right.[/tex]
Substitute the given value of x into the equation 5x + 8y = -1
5(-5/3+4/3y)+8y=-1
Solve the equation for Y
y=-1/2
Substitute the given value of y into the equation x = -5 / 3 + 4 / 3y
x=-5/3+4/3×1/2
Solve the equation for X
x=-1
The system solution is the computer pair

Simplify the equations
[tex]\left \{ {{-5=-5} \atop {-1=-1}} \right.[/tex]
The ordered pair is the solution of the system of equations, since both equations are true
(x,y)=(-1,1/2)

4x-2 +3x+7 = 180
7x + 5 = 180
7x = 175
x = 25
3(25) + 7 = 82
Answer:
82 (degrees)
Step-by-step explanation:
4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25
This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.
3(25) +7=82 which is equal to f

Answer:
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]
Step-by-step explanation:
equation of line formula:
[tex]y = mx + c[/tex]
m = slope
c = y-intercept
1) find m
slope formula:
[tex]m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
take 2 coordinates from the given graph and substitute the values into the slope formula
i) (-1,0)
[tex]x _{1} = - 1[/tex]
[tex]y_{1} = 0[/tex]
ii) (3,2)
[tex]x_{2} = 3[/tex]
[tex]y_{2} = 2[/tex]
substitute the values into the slope formula
[tex]m = \frac{2 - 0}{3 - ( - 1)} [/tex]
[tex]m = \frac{2}{4} [/tex]
[tex]m = \frac{1}{2} [/tex]
2) find the half equation of the line by substituting the value of m into the equation of line formula
[tex]y = \frac{1}{2} x + c[/tex]
3) find c by substituting either coordinate into the half equation
(3,2)
x = 3
y = 2
[tex]2 = \frac{1}{2} (3) + c[/tex]
[tex]2 = \frac{3}{2} + c[/tex]
[tex]2 - \frac{3}{2} = c[/tex]
[tex] \frac{1}{2} = c [/tex]
[tex]c = \frac{1}{2} [/tex]
4) find equation of line by substituting the value of c into the half equation
[tex]y = \frac{1}{2} x + \frac{1}{2} [/tex]

The population of a small town increased 23% from its population in 2000 to its population in 2003. If the population of the town in 2000 was 25,314, what was its population in 2003?
Answer:
31136
Step-by-step explanation:
To find the how much an number increased by a percent. Divide the percent by 100. 23/100=0.23.
Then multiply 0.23 by the original number which is 25,314. Which gives us about 5822.
Then since it INCREASED, we are going to add that number it increased to the original. 25314+5822= 31136.
Answer:
Good Luck, hope it helps:)
Step-by-step explanation:
23% of 25,314 = 25,314 x .23 = 5822 then add that to the original population. 25,314 + 5,822 = 31,136

you invested $1,900 at a 4% interest compounded annually for 3 years.how much interest did you earn in 3 years
Answer:
The amount is $2137.24 and the interest is $237.24.
Step-by-step explanation:
STEP 1: To find amount we use formula:
A = P[tex](1+\frac{x}{y} )nt[/tex]
A = total amount P = principal or amount of money deposited, r = annual interest rate n
= number of times compounded per year t = time in years In this example we have
P = $1900 , r = 4% , n = 1 and t = 3 years
After plugging the given information we have
A = 1900 [tex](1+\frac{0.04}{1})^{1*3}[/tex]
A = 1900 · 1.0[tex]4^{3}[/tex]
A = 1900 · 1.124864
A = 2137.24
STEP 2: To find interest we use formula A = P + I, since A = $2137.24 and P = $1900 we
have:
A = P + I
2137.24 = 1900 + I
I = 2137.24 − 1900
I = 237.24
