The perimeter of the right triangle is 30 units.
What is perimeter?
In geometry, perimeter refers to the total length of the boundary of a two-dimensional shape, such as a polygon or a circle. It is the sum of the lengths of all the sides of the shape.
To find the perimeter of the right triangle, we need to determine the lengths of its sides first.
Using the distance formula, we can find the lengths of the three sides of the triangle:
Side 1: From (-5, 3) to (-5, -2)
[tex]Length = \sqrt{[(3 - (-2))^2 + (-5 - (-5))^2]} = \sqrt{[5^2]} = 5[/tex]
Side 2: From (-5, -2) to (7, -2)
[tex]Length = \sqrt{[(7 - (-5))^2 + (-2 - (-2))^2]} = \sqrt{[12^2]} = 12[/tex]
Side 3: From (7, -2) to (-5, 3)
[tex]Length = \sqrt{[(-5 - 7)^2 + (3 - (-2))^2]} = \sqrt{[144 + 25]} = \sqrt{[169]} = 13[/tex]
We know that the triangle is a right triangle because two of its sides (Side 2 and Side 3) form a straight line along the x-axis, and the third side (Side 1) is perpendicular to this line.
Therefore, Side 1 is the hypotenuse, and Sides 2 and 3 are the legs of the right triangle.
To find the perimeter, we add up the lengths of all three sides:
Perimeter = Side 1 + Side 2 + Side 3 = 5 + 12 + 13 = 30
Therefore, the perimeter of the right triangle is 30 units.

Use separation of variables to find the general solution to the following differential equation.
Therefore, the general solution to the differential equation is
Y = e⁽ˣ⁾2+X+C) - 1 or Y = -e⁽ˣ⁾2+X+C) - 1
What exactly is a different equation?A differential equation is an equation that connects the derivatives of one or more unknown functions. It is an equation that uses the derivatives of a function or functions, in other words. Many physical processes, including the motion of objects under the influence of forces, the movement of fluids, and the spread of disease, are modelled using differential equations in science and engineering. Ordinary differential equations (ODEs) and partial differential equations (PDEs) are the two primary categories of differential equations.
To solve this differential equation using separation of variables, we first need to separate the variables Y and X on opposite sides of the equation:
dY / (Y + 1) = (2X + 1) dX
Following that, we incorporate both sides of the problem:
∫ dY / (Y + 1) = ∫ (2X + 1) dX
The integral on the left side can be evaluated using the substitution
u = Y + 1 and du = dY:
ln|Y + 1| = ∫ dY / (Y + 1) = ln |u| + C1
where C1 is the constant of integration.
The integral on the right side can be evaluated using the power rule of integration:
∫ (2X + 1) dX = X² + X + C2
where C2 is another constant of integration.
Putting these results together gives the general solution to the differential equation:
ln|Y + 1| = X² + X + C
where C = C1 + C2 is the combined constant of integration.
To solve for Y, we exponentiate both sides of the equation:
|Y + 1| = e⁽ˣ⁾2+X+C)
Taking into account the absolute value, we have two cases:
Case 1: Y + 1 = e⁽ˣ⁾2+X+C)
Y = e⁽ˣ⁾2+X+C) - 1
Case 2: Y + 1 = -e⁽ˣ⁾2+X+C)
Y = -e⁽ˣ⁾2+X+C) - 1
Therefore, the general solution to the differential equation DY/DX=(Y+1)(2X+1) is:
Y = e⁽ˣ⁾2+X+C) - 1 or Y = -e⁽ˣ⁾2+X+C) - 1

The town's emergency response planning committee wants to place four emergency response centers at the four corners of town Each would serve the people who live within 3 mi of the response center Sketch the loci of points for the areas served What are the problems with this idea ? What is one potential solution ?
The town's emergency response planning committee has proposed to place four emergency response centers at the four corners of the town, with each center serving the people who live within 3 miles of the respective response center. The idea is to provide coverage to the entire town and ensure prompt emergency response for the residents. However, there are some problems with this idea.
Unequal coverage: Placing the emergency response centers at the four corners of the town may result in unequal coverage for the residents. Depending on the size, shape, and population distribution of the town, some areas may be farther away from the response centers, resulting in longer response times and reduced effectiveness in emergency situations.
Overlapping coverage: Placing four response centers in a small town may result in overlapping coverage areas, where the coverage areas of multiple response centers overlap with each other. This may lead to duplication of resources and inefficiencies in emergency response efforts.
Limited reach: Placing response centers only at the four corners of the town may result in limited reach for certain areas, especially those located in the middle or farther away from the corners. This may leave some residents outside the 3-mile coverage radius without access to timely emergency response services.
One potential solution to address these problems could be to use a more strategic approach to determine the locations of the emergency response centers. This could involve conducting a thorough analysis of the town's population density, geographical features, road network, and existing emergency resources. Based on this analysis, the response centers could be strategically placed at locations that provide the best coverage to the entire town, considering factors such as response time, resource allocation, and accessibility.
For example, instead of placing all the response centers at the corners of the town, they could be distributed more evenly across the town to ensure more equitable coverage. Additionally, the use of advanced GIS (Geographical Information System) technology and modeling techniques could help in identifying optimal locations for the response centers, taking into account various factors such as population density, road network, and travel time.
Furthermore, collaboration and coordination among the emergency response centers, along with proper communication and information sharing, can help in avoiding duplication of resources and improving the efficiency of emergency response efforts.
In conclusion, while the idea of placing four emergency response centers at the four corners of town may seem simple, there are potential problems such as unequal coverage, overlapping coverage, and limited reach. A more strategic and data-driven approach, considering factors such as population density, geographical features, and existing resources, can help in identifying optimal locations for the response centers and ensuring effective emergency response services for all residents of the town.
A business has 40,000 to spend on advertising in an upcoming sale. The money is to be divided between television (x), radio (y) and newspapers (z). The business manager has decided to spend three times as much money on television as on radio. The manager has also decided to spend 8000 less on radio advertising than on newspapers. Find out, using matrix inversion method, the total amount divided between television, radio and newspapers.
Okay, let's break this down step-by-step:
* The business has $40,000 total to spend on advertising
* Some will go to TV (x), some to radio (y), and some to newspapers (z)
* 3 times as much will go to TV as radio, so x = 3y
* They will spend $8,000 less on radio than newspapers, so y = z - 8,000
* We have:
x = 3y (1)
y = z - 8,000 (2)
x + y + z = 40,000 (3)
To solve this using matrix inversion:
1) Turn the equations into a matrix:
3 1 0 y
1 -1 1 z
1 1 1 x
2 0 40,000
2) Invert the matrix:
0.3333 0.3333 0.3333
-0.25 0.75 0
0.125 0.125 0.750
3) Plug in the values from (2) and (3):
y = 0.3333(z - 8,000)
x = 0.125z + 0.125(40,000 - z)
4) Solve for z, the amount for newspapers. We get:
z = 40,000 * (0.75) = 30,000
5) Plug z = 30,000 back into the other equations:
x = 0.125 * 30,000 + 0.125 * 10,000 = 12,000
y = 0.3333 * (30,000 - 8,000) = 8,000
z = 30,000
So in total:
TV (x) = $12,000
Radio (y) = $8,000
Newspapers (z) = $30,000

y = |x - 5| + |x + 5| if x >5
Answer:
y = 2x
Step-by-step explanation:
You want the simplified form of y = |x -5| +|x +5| if x > 5.
Turning pointsThe graph of the whole function will have turning points where the absolute value expressions are 0:
x -5 = 0 ⇒ x = 5
x +5 = 0 ⇒ x = -5
For values of x > 5, we are concerned with that portion of the graph that is to the right of both of these turning points. Hence, both absolute value expressions are positive and unchanged by the absolute value bars.
y = (x -5) +(x +5) . . . . . . if x > 5

You invest $1850 in an account paying 5.2% interest compounded daily. What is the account's effective annual yield?
Answer: 5.36%
Step-by-step explanation:
The formula for the effective annual yield (EAR) when the interest is compounded daily is given by:
(1 + r/365)^365 - 1
where r is the annual interest rate.
In this case, the annual interest rate is 5.2% or 0.052. Substituting this value into the formula, we get:
(1 + 0.052/365)^365 - 1 = 0.0536
Multiplying this value by 100 gives the effective annual yield as a percentage:
0.0536 x 100 = 5.36%
Therefore, the effective annual yield of the account is 5.36%.
If you invest $3900 at a 7.84 simple annual interest rate, approximately how long will it take for you to have a total of $10,000
It would take approximately 19.94 years to accumulate a total of $10,000 from an initial investment of $3,900 at a simple annual interest rate of 7.84%.
To determine how long it will take to accumulate $10,000 from an initial investment of $3,900 at a simple annual interest rate of 7.84%, we can use the formula for simple interest:
I = Prt
where I is the interest earned, P is the principal or initial investment, r is the annual interest rate as a decimal, and t is the time in years.
To find the time required to reach a final amount of $10,000, we can rearrange the formula:
t = (I/P) / r
First, we need to calculate the interest earned on the initial investment:
I = Prt
I = (3900)(0.0784)t
I = 305.76t
To reach $10,000, we need to earn an additional $10,000 - $3,900 = $6,100 in interest. So we can set up the equation:
6100 = 305.76t
Solving for t, we get:
t = 6100 / 305.76
t ≈ 19.94 years

The monthly cost (in dollars) of a long-distance phone plan is a linear function of the total calling time (in minutes). The monthly cost for 39 minutes of calls is 18.45 and the monthly cost for 56 minutes is $20.66. What is the monthly cost for 50 minutes of calls?
Step-by-step explanation:
We can use the two data points given to find the equation of the line, which gives the monthly cost (y) in terms of the calling time in minutes (x).
First, we can find the slope of the line:
slope = (change in y) / (change in x)
slope = (20.66 - 18.45) / (56 - 39)
slope = 0.219
Next, we can use one of the data points and the slope to find the y-intercept (b). Let's use the data point (39, 18.45):
y - y1 = m(x - x1)
y - 18.45 = 0.219(x - 39)
y - 18.45 = 0.219x - 8.541
y = 0.219x + 9.909
So the equation for the monthly cost is y = 0.219x + 9.909.
To find the monthly cost for 50 minutes of calls, we plug in x = 50:
y = 0.219(50) + 9.909
y ≈ $21.44
Therefore, the monthly cost for 50 minutes of calls is approximately $21.44.

Answer:
ZR = 145°
Step-by-step explanation:
the secant- secant angle ZAR is half the difference of the measures of the intercepted arcs , that is
∠ ZAR = [tex]\frac{1}{2}[/tex] ( ZR - KV )
30 = [tex]\frac{1}{2}[/tex] (5x + 10 - (3x + 4) ) ← multiply both sides by 2 to clear the fraction
60 = 5x + 10 - 3x - 4
60 = 2x + 6 ( subtract 6 from both sides )
54 = 2x ( divide both sides by 2 )
27 = x
Then
ZR = 5x + 10 = 5(27) + 10 = 135 + 10 = 145°
You drop a ball from a height of 1.5 meters. Each curved path has 71% of the height of the previous path.
a. Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.
b. What height will the ball be at the top of the sixth path?
a) The rule that represents the height as a function of the number of bounces is described by H(n) = 1.5 · (71 / 100)ˣ⁻¹. (Correct choice: B)
b) The height at the top of the sixth path is equal to 0.27 meters. (Correct choice: B)
How to represent a bounces of a ball by geometric sequence formula
In this problem we need to derive the equation that represents maximum height as a function of the number of bounces:
H(n) = a · (r / 100)ˣ⁻¹
Where:
a - Initial height, in meters.r - Height ratio, in percentage. x - Number of bounces.If we know that a = 1.5 m and r = 71, then the rule for the sequence is:
H(n) = 1.5 · (71 / 100)ˣ⁻¹
And the height at the top of the sixth path:
H(6) = 1.5 · (71 / 100)⁶⁻¹
H(6) = 0.27 m

5. - 1 5/7 divided by 1/2
Answer: -3 3/7
Step-by-step explanation:
First, you can convert -1 5/7 to an improper fraction by multiplying the denominator with the whole number, then add the answer to the numerator. Like this:
7 × 1 = 7
7 + 5 = 12
12 will be your numerator and 7 will be your denominator. When you're done converting, bring down the negative sign. The fraction should be:
-12/7
Now, since -1 5/7 is -12/7, we can divide.
To divide, we can use, KCF (Keep, Change, Flip)
First, keep -12/7.
Second, change division to multiplication.
Third, flip 1/2.
Your problem will be set up like:
-12 /7 × 2/1
Now, we can solve. Multiply both the numerator AND the denominator. Since you're multiplying, you don't have to change the denominator to match each other. The answer will be:
-24 / 7
However, this fraction is improper. We can use long division to make this fraction proper.
Divide 24 and 7. You'll get 3, with a remainder of 3.
The remainder will be the new numerator and the answer will be the whole number.
3 - Remainder (Whole Number)
3 - Answer (New Numerator)
7 - Dividend (Original Denominator) Will not be changed
Hence, your final answer is:
-3 3/7

If you transform y = 2x2 into y = 10x2, which option below describes the effect of this transformation on the graph of the quadratic function along the y-axis?
(b) The transformation stretches the graph by a factor of 5 describes the effect of this transformation on the graph of the quadratic function along the y-axis.
The transformation from y = 2x² to y = 10x² changes the coefficient of the x² term from 2 to 10. This change in the coefficient affects the vertical scaling of the graph of the quadratic function along the y-axis. When we multiply the entire function by a constant, it causes a vertical stretch or compression of the graph depending on the magnitude of the constant.
In this case, the transformation stretches the graph along the y-axis by a factor of 5 since 10 is 5 times greater than 2. This means that the vertical distance between the points on the graph of the function is now 5 times greater than before the transformation.
Therefore, the correct option is (b) - The transformation stretches the graph by a factor of 5.
Correct Question :
If you transform y = 2x2 into y = 10x2, which option below describes the effect of this transformation on the graph of the quadratic function along the y-axis?
