True or False: If f(x) = -3x^3 + 2(x + 2), then f(-2) = 24
Answer:
True
Step-by-step explanation:
When you plug in -2 for the x-values, it should be like this -3(-2)^3 + 2((-2)+2). When using the method of PEMDAS, you want to do the parentheses/exponents first since it is in order. -2 to the power of 3 is -8 for this case. Distribute 2 in -2 and 2 to get -4 + 4. Obviously. they will cancel in which you are left with -3(-8). Two negatives multiplied together equals a positive, so your final answer should be 24, in this case it is true.

Are the lines x− 2y= 4 and y= 2x − 2 parallel, perpendicular, or neither? Explain your answer. [ Select ] ; their [ Select ] [ Select ] the same and [ Select ] receiprocals.
Answer:
Neither.
Step-by-step explanation:
First we alter the first equation to match the second.
x - 2y = 4
2y = x - 4
y = x/2 - 2.
Next we compare the slopes
2x = 2
x/2 = 1/2
Their slopes are reciprocals, but they aren't opposites. Therefore they are neither parallel nor perpendicular.

Victor wants to purchase a perpetuity paying 100 per year with the first payment due at the end of year 11. He can purchase it by either: (i) paying 90 per year at the end of each year for 10 years; or i) payıng K per year at the end of each year for the years and nothing for the next 5 years. Calculate K
Answer:
K = 151.9422481
Step-by-step explanation:
At the end of year 10, your perpetuity is worth 100/i
(1) is worth 90×s_{10%i}
So if you set them equal you get 90*[(1+i)^10 - 1]/i = 100/i or [(1+i)^10 - 1] = 10/9 or (1+i)^10 = 19/9 or i = 0.077583937
So now the question compare (1) to (2), at t = 0
(1) is worth 90×a_{10%i} = 90(1 - 1/(1.077583937)^10)/0.077583937 = 610.5441743
(2) is worth K×a_{5%i} = 4.018264714×K
Therefore K = 151.9422481
Triangle ABC contains side lengths b=3 inches and c= 5 inches in two or more sentences describe whether or not it is possible for mangle B =45 degrees
Answer:
Since sine of all angles are always less than one, this shows there is no possible way to have an angle C. Thus it is impossible to have a triangle ABC with the given properties of side lengths b=3 inches and c= 5 inches to have angle B =45 degrees.
Step-by-step explanation:
In the attached drawing, each of the tic-marks are equal and
represent 1 inch each. The angle B has measure 45. We can
see by the arc that the line AC, which equals 3 inches, is
not long enough to reach the slanted side of the 45 angle.
Therefore triangle ABC is not possible. We can also show
by the law of sines that no triangle ABC with the given
properties in possible.

Answer:
Width = 66 inches
Step-by-step explanation:
Zelda has 300 inch roll of binding for a quilt.
The length must be 84 inches
We need to find its width. Let it is b.
Let us assume that the quilt is in the shape of rectangle. The perimeter of the rectangle is given by :
P = 2(l+b)
300 = 2(84+b)
150 = 84+b
b = 150-84
b = 66 inches
So, the required width is 66 inches.

Mel slides down waterslide A, and Victor slides down waterslide B. After 2 seconds, Mel was 50 feet in the air, and after 5 seconds, she was 35 feet in the air. After 1 second, Victor was 60 feet in the air, and after 4 seconds, he was 50 feet in the air. Who was descending at a faster rate?
Answer:
Mei descends faster
Mei's height decreases 5ft every second
Victor's height decreases 3.33 ft every second
Step-by-step explanation:
Given
Mel
[tex](x_1,y_1) = (2,50)[/tex]
[tex](x_2,y_2) = (5,35)[/tex]
Victor
[tex](x_1,y_1) = (1,60)[/tex]
[tex](x_2,y_2) = (4,50)[/tex]
Required
Who descend faster?
To do this, we simply calculate the slope/rate of both individuals
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For Mei:
[tex]m_1 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex](x_1,y_1) = (2,50)[/tex]
[tex](x_2,y_2) = (5,35)[/tex]
[tex]m_1 = \frac{35 -50}{5 - 2}[/tex]
[tex]m_1 = \frac{-15}{3}[/tex]
[tex]m_1 = -5[/tex]
Mei descends at 5ft per second
For Victor:
[tex]m_2 = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex](x_1,y_1) = (1,60)[/tex]
[tex](x_2,y_2) = (4,50)[/tex]
[tex]m_2 = \frac{50-60}{4 - 1}[/tex]
[tex]m_2 = \frac{-10}{3}[/tex]
[tex]m_2 = -3.33[/tex]
Victor descends at 3.33ft per second
By comparison:
Mei descends faster

Write a polynomial that represents the area of the square 7n-5, plz help, thank you!
Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25

Complete the following statement. Percent is a fraction where parts make one whole.
Answer:
Percent is a fraction where the denominator is represented by 100 or 100 parts make one whole.
Step-by-step explanation:
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
A percentage is a fraction whose denominator is 100, or how many parts make one whole.
What is percent?A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred. The word "per 100" means "per percent." The number "%" is used to symbolize it.
For given statement
A fraction with 100 as the denominator is called a percent.
Thus, a whole is made up of 100 parts. The percentage represents the number of relevant parts out of a total of one hundred.
For instance, 10% is represented by the decimal number 0.10 or the fraction 10/100.
Similarly, the decimal equivalent of 25% is 0.25, or the fraction 25/100.
Because 100/100 equals 1, 100% corresponds to the number 1.
Hence the statement is Percent is a fraction where the denominator is represented by 100 or 100 parts make one whole.

The rectangular front windshield of the bus has the length of 1.5√3 m and the width of 1.5 m . The wipers are attached to the bottom corners. If the length of each wiper is equal to the width of the windshield, find the percentage of the windshield that wipers can reach.
(Solve this task without using Trigonometry)
See the attached sketch. From their respective corners, each wiper sweeps out a portion of the total area of the windshield equal to the area of a quarter-circle with radius 1.5 m (shaded green), and they overlap in a half-lens-shaped region (shaded red). The area that the wipers together cover is equal to the sum of the green areas minus the area of the red overlap. It's easy to see that this red area is equal to the area of the highlighted circular segment (bordered in blue).
Not sure how exactly you can avoid finding the area of the segment without resorting to trigonometry, though... The radii AC and AD form an angle θ such that the segment has area
1/2 (1.5 m)² (θ - sin(θ))
but you can avoid mentioning the sine function by writing it as
1/2 (1.5 m)² (θ - √3/2)
which follows from
sin(θ) = 2 sin(θ/2) cos(θ/2) = 2 ((BD/2)/AB) ((AC/2)/AB)
and the fact that BD has length equal to the radii, since by the Pythagorean theorem
(AC/2)² + (BD/2)² = AB²
(whether this theorem falls under trigonometry is also up for debate)
You would need trig to find the measure of the angle θ as well, unless you just take for granted the fact that a triangle with side lengths 1.5√3/2, 1.5/2, and 1.5 (i.e. AC/2, BD/2, and AB), since they occur in a ratio of √3 : 1 : 2 is a 30°-60°-90° triangle, so that θ = 60° = π/3 rad.
At any rate, the percentage is about (2×(quarter-circle area) - (segment area))/(rectangle area) = 85.46%, since
• area of rectangle = (1.5 √3 m) • (1.5 m) ≈ 3.897 m²
• area of quarter-circle = π/4 (1.5 m)² ≈ 1.767 m²
• area of segment = 1/2 (1.5 m)² (π/3 - √3/2) ≈ 0.204 m²

The area of coverage is the sum of two sectors of 60° and a triangle.
Find each area and calculate the percentage of covered region
Rectangle area:
A = 1.5*1.5√3 = 9√3/4 ≈ 3.8971Triangle height
h = √1.5² - (1/2*1.5√3)² = √1/4*1.5² = 1.5/2 = 3/4Since h is half of the hypotenuse, the opposite angle is 30°This leaves each sector 60°Triangle area
A = 1/2*1.5√3*3/4 = 9√3/16 ≈ 0.9742Sectors' area
A = 2*1/6*πr² = 1/3π(1.5)² = 3π/4 ≈ 2.3561Area covered by wipers
A = 0.9742 + 2.3561 = 3.3303Percentage of covered region:
