Answer:
Step-by-step explanation:
After translation 5 units the vertices become L'(5,1), M'(6, - 2) and N'( 3,1).
The figure is attached below.
Use the concept of coordinate defined as:
A pair of numbers that describe the exact position of a point on a cartesian plane by using horizontal and vertical lines is called the coordinates.
The given vertices are:
L(0,1), M(1, - 2), and N( –2,1)
Since it is translating 5 units right.
Therefore,
x-coordinate of each vertex increased by 5 units.
So, the new position of vertices after translation is:
L(0,1) transformed into L'(5,1)
M(1, - 2) transformed into M'(6, - 2)
N( –2,1) transformed into N'( 3,1)
Hence the figure is attached below.

what does 130°30' mean
130 degrees and 30 minutes
That's minutes as in arc-minutes, a sub-division of a degree. 1 degree is made up of 60 minutes.
So 130°30' is the same as 130° + 30/60° = 130.5°.

Windmills are used to generate electricity. Suppose a particular windmill has a blade that is 140 ft long from the center of its mounting.
When the blade makes one complete rotation, how far (in ft) does the tip of the blade travel?
What is the surface area (in acres) that the rotating blades cover?
When the blade makes one complete rotation, how far (in ft) does the tip of the blade travel?
Because the blade is 140, we that means the radius is 140. So we need to find the circumference of the circle.
C=2πr
C = (2)(3.14)(140)
C = 879.2 ft
The blade travels 879.2 feet
What is the surface area (in acres) that the rotating blades cover?
A = πr²
A = (3.14)(140)²
A = (3.14)(19600)
A = 61544 ft²
An acre = 43,560 feet
61544 / 43560 = 1.41285583

Help with what?
Step-by-step explanation:
There is no question.
Part A: The area of a square is (4x2 + 20x + 25) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points)
Part B: The area of a rectangle is (4x2 − 9y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)
Answer:
Step-by-step explanation:
4x² + 20x + 25 = (2x)² + 2* 2x *5 + 5²
{Compare with a² + 2ab + b² = (a+ b)²}
= (2x + 5)²
= (2x +5)*(2x+5)
Side of the square = 2x+ 5
Answer:
Part A is (2x+5)^2. Part B is (2x+3y)(2x-3y).
Step-by-step explanation:
Part A: The polynomial is prime. When you split the middle term, it becomes 4x^2+10x+10x+25. Then rewrite using the common factor from the two pairs. 2x(2x+5)+5(2x+5). Rewrite in factored form, which is (2x+5)(2x+5). Then combine which is, (2x+5)^2. The length of each side is (2x+5)^2.
Part B: The polynomial is prime. Rewrite 4x^2 as (2x)^2 and 9y^2 as (3y)^2, which looks like (2x)^2-(3y)^2. Both terms are perfect squares. The answer is (2x+3y)(2x-3y).

High demand cars that are also in low supply tend to retain their value better than other cars. The data in the table are for a car that won a resale value award.
Enter a function to represent the car's value over time, assuming that the car's value is linear for the first 5 years.
According to your model, how much did the car's value drop the day it was purchased and driven off the lot?
Do you think the linear model would still be useful after 10 years? Explain.
uppose you used months instead of years to write a function. How would your model change
Answer:
No because its -10 per year so after 10 years the car value will go below zero which makes it useless
Step-by-step explanation:
Step-by-step explanation:
Given the table of values where it represents the relationship between the change in value of a car and number of years.
Slope:Before we can establish the linear equation, we need to determine its slope by using two ordered pairs from the table.
Let (x₁, y₁) = (1, 84)
(x₂, y₂) = (3, 64)
Substitute these values into the following slope formula:
m = (y₂ - y₁)/(x₂ - x₁)
m = (64 - 84)/(3 - 1)
m = -20/2
m = -10
Therefore, the slope of the linear function is -10.
1. Enter a function to represent the car's value over time, assuming that the car's value is linear for the first 5 years.Assuming that the car's depreciation in value is linear for the first 5 years, then we can establish the following function:
Next, using one of the given ordered pairs from the table, (1, 84), and the slope, m = -10, substitute these values into the slope-intercept form to solve for the value of the car at x = 0 (the y-intercept, b ):
84 = -10(1) + b
84 = -10 + b
Add 10 to both sides to isolate b:
84 + 10 = -10 + 10 + b
94 = b
Therefore, the linear function is f(x) = -10x + 94.
To verify whether this is the correct function to represent the given linear model, substitute the values for year 5, where the car's value is at 44%:
f(5) = -10(5) + 94
f(5) = -50 + 94
f(5) = 44 ⇒ This matches the value from the given table, where it implies that at year 5, the value of the car is 44%.
2. According to your model, how much did the car's value drop the day it was purchased and driven off the lot?Since the car's value is expressed in percentage (%), then it means that at year = 0, the car's value is 100%. The value of the car in year 1 is 84%.
Therefore, the car's value will decrease by 16% from the day it was purchased (at year = 0) through year 1.
To determine the value of the car the day it was purchased and driven off the lot:
Let x = 1 out of 365 days = 1/365 = 0.0027
f(0.0027) = -10(0.0027) + 94
f(0.0027) = -10(0.0027) + 94
f(0.0027) = -0.027 + 94
f(0.0027) = 93.973
The car's value at Day 1 is 93.97%, which means that it decreased by 6%.
3. Do you think the linear model would still be useful after 10 years? Explain.In order to determine whether the linear model would still be useful after 10 years, let x = 10:
f(x) = -10x + 94
f(10) = -10(10) + 94
f(10) = -100 + 94
f(10) = -100 + 94
f(10) = -6
The value of the car by the 10th year will be -6%, implying that it is no longer useful by year 10. The linear model is only useful up to the 9th year:
f(9) = -10(9) + 94
f(9) = -90 + 94
f(9) = 4 ⇒ The car's value by the 9th year is 4%.
4. Suppose you used months instead of years to write a function. How would your model change?Since in the original function, x represents the number of years, and there are 12 months in a year:
Let 12x = 12 months × 1 year
Substitute 12x as an input into the original function:
f(x) = -10x + 94
f(x) = -10(12x) + 94
f(x) = -120x + 94 ⇒ This represents the function that models linear relationship between the percentage value of a car relative to the number of months that the car is driven.
A 250-foot length of fence is placed around a three-sided animal pen.
Two of the sides of the pen are 100 feet long each. Does the fence
form a right triangle? Prove that your answer is correct.
Step-by-step explanation:
no it does not form a right triangle.
a+b+c = 250
1002 + 502 does not equal 1002
nor 1002 + 1002 does not equal 502
so therefore the sides are 100, 100, and 50 but these do not make a right triangle

Moneysaver's Bank offers a savings account that earns 8% interest compounded continuously. If Kareem deposits $3100, how much will he have in the account
after two years, assuming he makes no withdrawals?
Do not round any intermediate computations, and round your answer to the nearest cent.
Using continuous compounding, it is found that he will have $3,615.84 in the account after two years.
The amount of money in an account that uses continuous compounding, after t years, is given by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the deposit.r is the interest rate, as a decimal.In this problem:
Deposit of $3,100, hence [tex]A(0) = 3100[/tex]Interest rate of 8%, hence [tex]r = 0.08[/tex]Then, after 2 years, we have t = 2, hence:
[tex]A(t) = A(0)(1 + r)^t[/tex]
[tex]A(2) = 3100(1 + 0.02)^2 = 3615.84 [/tex]
He will have $3,615.84 in the account after two years.

If y = ax² + bx + c is the general form of a quadratic function, what is y = a(x - h)² + k? *
a. vertex form
b. general equation
c. point-slope form
d. slope-intercept form
How necessary is the value of a, b and c in transforming quadratic function from general to vertex form? *
a. to find the value of h and k
b. to find the number of roots
c. to determine the degree of the quadratic function
d. to determine the maximum point
Step-by-step explanation:
it is the vertex form.
remember, (h, k) is the vertex point.
the vertex being the point of the (quadratic) parabola, where the curve turns around.
depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.
so, the first a. is correct.
and so is the second a., as they play an important role when completing the square and hence finishing the transformation.

Write an equation of the line in slope-intercept form.
The equation is y=
.
Answer:
y = x + 2
Step-by-step explanation:
Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Here, b is equal to 2 because the line crosses the y-axis at 2. THe slope is rise over run, or the change in y divided by the change in x. From the two points given, we get 3/3 which is equal to 1. 1x equals x, so this gives us "no slope." Putting it together gives us y = x + 2.
