Hey!
If a car is losing value at a constant rate, then a linear function would work better. For example, say that a car dealership is buying used cars. They will buy it for the asking price, but subtract 500 dollars for each year the car has been in existence. So, if you had a car from 2015 that cost you $2,000, and it's 2018, the dealership would buy it for 2000-(500 * the amount of years it has been since the car was made). Therefore, as 2018-2015=3, we have 2,000-500*3=2,000-1,500=500 as the value of the car after three years, and linear function (in the form of
, with y representing the end cost, b representing the starting cost, m representing the amount the car depreciates in value every year, and x being the amount of years) is 500=(-500*3+2000) in our situation here. Similarly, if the minivan depreciates 3,000 dollars in the first year, based on our knowledge and being forced to use linear function, we can assume that the minivan loses 3,000 dollars every year, making our equation y=(-3000*x)+29,248, with y representing the value of the car at the end, x representing the amount of years, and b representing the starting cost.
However, say that the car loses 50% of its value every year. This means that if you originally bought a car for 2,000 dollars in 2015, in 2016 it would be world 2,000/2=1,000 , 1,000/2=500 the year after that, and so on. We can try to put this into a linear function, but it's hard to put into one equation because we're not subtracting or adding to the cost of the car by a specific amount each year. If we had our equation as y=-0.5*x+2000, this wouldn't work because it's adding to the original amount, not multiplying. However, if we used an exponential equation such as y=b(m^a), with y representing the end cost, b representing the starting cost, m representing the amount multiplied per year, and a representing the amount of years. This works because we start with a value, and multiply it by an amount each year. Since 50%=0.5, we plug that into m to get y=2,000(0.5^a). Therefore, this works really well here. If the minivan were to depreciate by 3,000 every year, starting at $29,248, this means that we first have to find out what we multiply 29,248 by the first year to subtract 3,000. As, after one year, the value is 29,248-3,000=26,248, we have 26,248=29,248(m^1). Therefore, we can divide 29,248 by both sides to get around 0.9 as our answer for m. Thus, our equation is y=29,248(0.9^a). This type of equation would not work if we subtracted an amount every year because we're not multiplying by the same amount then. For example, if a toy was valued at 3$ and gained a value of one dollar every year, we could multiply the toy by 4/3 the first year to get 4, but the next year we wouldn't get 5.

A cylindrical block of cheese has a 6-inch diameter and is 2 inches thick. After a party, only a sector remains that has a central angle of 45 degrees. Find the volume of the cheese that remains. Show all work
Answer: The volume of cheese remaining is 7 cubic inches (7 in³)
Step-by-step explanation: The cheese is in the shape of a cylinder. The volume of a cylinder is given as follows;
Volume = πr²h
Where r = radius of the top of the cylinder and h = the height of the cylinder.
In this case, the cheese has its radius as 3 inches (that is diameter divided by 2). Also the height is given as the thickness of the cheese which is 2 inches. Note also that part of the cylindrical cheese has been eaten leaving only a potion which has an angle of 45 degrees.
The volume of the left over portion therefore can be calculated as follows;
Volume = (∅/360) x πr²h
Volume = (45/360) x 3.14 x 3² x 2
Volume = (1/8) x 3.14 x 9 x 2
Volume = (1/8) x 56.52
Volume = 7.065
Volume ≈ 7
Therefore the volume of cheese that remains is 7 cubic inches (7 inches³) approximately.

Step-by-step explanation:
AB = AC (given)
Therefore, ∆ ABC is an isosceles triangle.
m<B=m< C= 40°
sum of the interior angles of a triangle= 180°
m<A+40°+40°=180°
m<A = 180°-80° = 100°
Answer:
< A is 100
Step-by-step explanation:
<B is 40 <C is also 40
so 40+40= 80 then you have to do 180-80. Which equals 100.
Is the leading coefficient of the function positive or negative?
Answer:
Negative.
Step-by-step explanation:
To understand the question, you first must understand the slopes of different types of equations.
A linear equation: [tex]y = 2x[/tex] will travel from the third quadrant to the first.
If you plug in 2 for x, y will equal 4. Both values are positive, leading to a positive correlation.
A linear equation: [tex]y = -3x[/tex] will face the other direction, as shown in your attached image. When you plug in a positive number for x, like 5, y will equal -15, making the graph go up and left towards negative values.
On a coordinate plane, line A goes through points (negative 3, 0) and (0, 4), and line B goes through points (0, negative 4) and (2, 0). Which line has the steeper slope? Line has a steeper slope
Answer:
Line B
Step-by-step explanation:
I got it right
Line B has a steeper slope than line A because its slope is greater than the slope of line A.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
For line A, the two points are (-3, 0) and (0, 4).
Plugging these values into the formula, we get:
slope = (4 - 0) / (0 - (-3)) = 4 / 3
For line B, the two points are (0, -4) and (2, 0).
Plugging these values into the formula, we get:
slope = (0 - (-4)) / (2 - 0) = 4 / 2 = 2
Therefore, line B has a steeper slope than line A, because its slope is greater than the slope of line A. Line A has a slope of 4/3, while line B has a slope of 2.
We can also visualize this by drawing the lines on a coordinate plane. Line B will have a more steeply inclined slope than line A, as it will rise more quickly as it moves from left to right.

Ina city school, 65% of students have green eyes. 25% have red hair, and 15% have green eyes and
red hair. What is the probability (rounded to the nearest whole percent) that a randomly selected
student will have red hair given that the student has green eyes?
Answer:
23% of student will have red hair given that the student has green eyes.
Step-by-step explanation:
We are given the following in the question:
Percentage of students that have green eyes = 65%
[tex]P(G) =0.65[/tex]
Percentage of students that have red hairs = 25%
[tex]P(R) =0.25[/tex]
Percentage of students that have green eyes and red hairs = 15%
[tex]P(G\cap R) =0.15[/tex]
We have to find the conditional probability of randomly selected student that will have red hair given that the student has green eyes.
[tex]P(R|G) = \dfrac{P(R\cap G)}{P(G)}[/tex]
Putting values, we get,
[tex]P(R|G)=\dfrac{0.15}{0.65} = 0.2307\approx 23\%[/tex]
Thus, 23% of student will have red hair given that the student has green eyes.

what is the probability of NOT winning a cash prize if the game is played on time?
A) 7/10
B) 1/5
C) 4/5
D) 3/10
Given:
It is given that
Probability of winning $ 0 = [tex]\frac{3}{10}[/tex]
Probability of winning $ 100 = [tex]\frac{1}{5}[/tex]
Probability of winning $ 200 = [tex]\frac{1}{10}[/tex]
Probability of winning $ 500 = [tex]\frac{2}{5}[/tex]
To find the probability of not winning a cash prize.
Explanation:
Not winning cash prize = winning $ 0
So,
Probability of not winning a cash prize
= Probability of winning $ 0
= [tex]\frac{3}{10}[/tex]
Therefore,
The probability of not winning a cash prize is [tex]\frac{3}{10}[/tex]. Option D.
The correct option is D. 3 / 10.The probability of not winning a cash prize when playing the game is 3/10. This is found by subtracting the total probability of winning (7/10) from 1.
To determine the probability of NOT winning a cash prize, we need to find the combined probability of all outcomes except those with a cash prize ($100, $200, $500). According to the table:
→ The probability of winning $100 is 1/5.
→ The probability of winning $200 is 1/10.
→ The probability of winning $500 is 2/5.
→ First, we calculate the total probability of winning a cash prize:
= 1/5 + 1/10 + 2/5
= 2/10 + 1/10 + 4/10
= 7/10
→ Now, the probability of NOT winning a cash prize is:
= 1 - 7/10
= 3/10
Therefore, the probability of not winning a cash prize when the game is played is Option D) 3/10.

Find the Area of the figure below, composed of a rectangle and one semicircle,
with another semicircle removed. Round to the nearest tenths place.
The Area of the figure below, composed of a rectangle and one semicircle, with another semicircle removed is 150 cm².
Length of the rectangle = 15cm.
Width of the rectangle = 10cm.
Diameter of semicircle = 10cm.
Therefore the radius of semicircle = diameter of semicircle/2
Therefore the radius of semicircle = 10/2 = 5cm.
Area of the given figure = Area of rectangle + Area of semicircle - Area of semicircle.
So, area of the given figure = Area of rectangle.
Area of rectangle = length × width
Area of rectangle = 15 × 10 = 150 cm²
Therefore the area of the figure below, composed of a rectangle and one semicircle, with another semicircle removed is 150cm².

Rounded to the nearest tenth, the area of the figure is 150.0 square units.
To find the area of the figure composed of a rectangle and two semicircles, with one semicircle removed, you can follow these steps:
Calculate the area of the rectangle.
Calculate the area of the larger semicircle.
Calculate the area of the smaller semicircle (the one that's removed).
Subtract the area of the smaller semicircle from the sum of the area of the rectangle and the larger semicircle.
Given that the dimensions of the rectangle are 15 by 10, the radius of the semicircle is half the width of the rectangle, so it's 10/2 = 5.
Area of Rectangle:
Area_rect = length x width = 15 x 10 = 150 square units
Area of Larger Semicircle:
The radius of the larger semicircle is 5 units (half of the width of the rectangle).
Area_larger_semicircle = (1/2) x π x r^2
Area_larger_semicircle = (1/2) x π x 5^2 = (1/2) x π x 25 = 12.5π square units
Area of Smaller Semicircle (the one that's removed):
This is also a semicircle with a radius of 5 units.
Area_smaller_semicircle = (1/2) x π x 5^2 = (1/2) x π x 25 = 12.5π square units
Subtract the area of the smaller semicircle from the sum of the area of the rectangle and the larger semicircle:
Total Area = Area_rect + Area_larger_semicircle - Area_smaller_semicircle
Total Area = 150 + 12.5π - 12.5π
The "12.5π" terms cancel out when you subtract them, so you're left with:
Total Area = 150 square units
Rounded to the nearest tenth, the area of the figure is 150.0 square units.

circumference of 18.84 yards.
Answer:
28.25
Step-by-step explanation:
Final answer:
The area of a circle with a circumference of 18.84 yards is approximately 28.274 square yards, found by first calculating the radius from the circumference and then using the area formula πr².
Explanation:
To find the area of a circle with a given circumference, we first need to determine the radius of the circle using the circumference. The formula to find the circumference C is C = 2πr, where r is the radius of the circle and π (pi) is approximately 3.14159. Since we are given that the circumference C is 18.84 yards, we solve for the radius r as follows:
r = C / (2π)
r = 18.84 yd / (2 × 3.14159)
r = 3 yards (approximately)
Once we have the radius, we can calculate the area of the circle using the formula:
A = πr²
A = π × (3 yd)²
A = 3.14159 × 9 yd²
A = 28.274 yards² (approximately)
Therefore, the area of the circle with a circumference of 18.84 yards is roughly 28.274 square yards.
