Hello could anyone help me with this problem? It’s a review question but i am having difficulty understanding how the triangle is drawn/how to solve it in general. Thanks!
Question: A ski lift starts at a point one half mile from the base of a mountain whose face has a 65 degree angle of elevation. The ski lift ascends at an angle of 15 degrees.
What is the length of the ski lift from the beginning to the end?
To solve this problem, we can use the trigonometric functions sine, cosine, and tangent.
First, let's draw a diagram:
A (top of the mountain)
/|
/ |
/ | h (height of mountain)
/ |
/ θ |
B /_____|
d (distance from base)
We are given that the distance from the base of the mountain to point B is 1/2 mile, or 2640 feet (since there are 5280 feet in a mile). We are also given that the angle of elevation from point B to point A is 65 degrees, and that the angle between the ski lift and the ground is 15 degrees.
Let's start by finding the height of the mountain h. We can use the tangent function, since we know the opposite (h) and the adjacent (d) sides of the right triangle formed by points A, B, and the foot of the mountain (call it point C):
tan(65) = h / d
h = d * tan(65)
Plugging in the values, we get:
h = 2640 * tan(65)
h ≈ 7855 feet
Next, let's find the length of the ski lift. We can use the cosine function, since we know the adjacent (d) and hypotenuse (L) sides of the right triangle formed by points B, the foot of the mountain, and the base of the ski lift (call it point D):
cos(15) = d / L
L = d / cos(15)
Plugging in the values, we get:
L = 2640 / cos(15)
L ≈ 2736 feet
Therefore, the length of the ski lift from the beginning to the end is approximately 2736 feet.
convert to slope intercept form ( y=mx+b)
2x+5y=0
Original Equation:
2x + 5y = 0
Explanation:
The slope intercept form is y = mx + b, so first we have to get x onto the other side, to do that, we subtract 2x from both sides and end up getting:
5y = - 2x
Now we divide both sides by 5 to isolate y
[tex]y = -\frac{2}{5} x[/tex]
That's our equation!

(A). the current sale price of the computer system is $543.20.
Therefore, members of the store's loyalty club pay $488.88 for the computer system with their discount.
Find the current sale price. Round to the nearest cent if necessary.
• Members of the store's loyalty club get an additional 10% off their computer purchases. How much do club members pay for the computer with their discount?
To find the current sale price, we first need to calculate the markdown amount. We know that the markdown is 30% of the original selling price, which is $776, so the markdown amount is:
30% of $776 = 0.30 x $776 = $232.80
The sale price is then the original selling price minus the markdown amount:
Sale price = $776 - $232.80 = $543.20
Therefore, the current sale price of the computer system is $543.20.
Next, we need to calculate the price that club members pay after their discount. We know that club members get an additional 10% off the sale price, which is $543.20, so their discount amount is:
10% of $543.20 = 0.10 x $543.20 = $54.32
The price that club members pay is then the sale price minus their discount amount:
Price for club members = $543.20 - $54.32 = $488.88
Therefore, members of the store's loyalty club pay $488.88 for the computer system with their discount.

ALG 2 imaginary numbers (EVEN ONLY)
Imaginary Numbers are 21. (5+2i)/ 4i is -(5/4) + (1/2)i, 22. 3i/(-2+i) is -1.5i + 0.75. 23. (3-2i)/(4-3i) is 4/5 + (1/25)i, 24. 7/(5-2i) is (14/29) + (7/29)i.
Describe Imaginary Numbers?In mathematics, imaginary numbers are a type of complex number that can be written in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1.
Imaginary numbers were first introduced in the 16th century as a solution to certain polynomial equations that did not have real solutions. They were initially met with skepticism and derision, but eventually became widely accepted as a fundamental part of complex analysis and number theory.
One of the key properties of imaginary numbers is that when they are multiplied by themselves, the result is always a negative real number. For example, i * i = -1. This property is what makes imaginary numbers useful for representing certain physical quantities, such as the amplitude and phase of an oscillating system.
21. (5+2i)/ 4i = -(5/4) + (1/2)i
To divide complex numbers, we can multiply the numerator and denominator by the conjugate of the denominator. Here, the conjugate of 4i is -4i.
(5+2i)/ 4i = (5+2i)/4i * (-4i/-4i)
= -(20i - 8)/(-16)
= -(20i - 8)/16
= -(5/4) + (1/2)i
Therefore, (5+2i)/ 4i = -(5/4) + (1/2)i.
22. 3i/(-2+i) = -1.5i + 0.75
We can again use the conjugate to simplify the division of complex numbers.
3i/(-2+i) = 3i/(-2+i) * (-2-i)/(-2-i)
= (-6i -3)/(-5)
= 3/5 + 1.5i
Therefore, 3i/(-2+i) = -1.5i + 0.75.
23. (3- 2i)/(4-3i) = (18+5i)/25
Using the conjugate:
(3-2i)/(4-3i) = (3-2i)/(4-3i) * (4+3i)/(4+3i)
= (12+9i-8i-6i²)/(16+12i+12i-9i²)
= (20+i)/25
= 20/25 + (1/25)i
= 4/5 + (1/25)i
Therefore, (3-2i)/(4-3i) = (18+5i)/25 = 4/5 + (1/25)i.
24. 7/(5-2i) = (14/29) + (7/29)i
Using the conjugate:
7/(5-2i) = 7/(5-2i) * (5+2i)/(5+2i)
= (35+14i)/(29)
= (14/29) + (7/29)i
Therefore, 7/(5-2i) = (14/29) + (7/29)i.

A hemisphere over the cone with a radius of 10 cm and a height of 15 cm.
a) volume of the cone: V = 1570.8 cm³
b) volume of the hemisphere: V = 2093.33 cm³
c) voume of the entire figure : V= 3664.13 cm³
a) The formula V = (1/3)r2h, where r is the cone's radius and h is its height, determines the volume of the cone.
Substituting r = 10 cm and h = 15 cm, we get:
V = (1/3)π(10 cm)²(15 cm)
V ≈ 1570.8 cm³
The volume of the cone is approximately 1570.8 cm³.
b) The volume of the hemisphere is given by the formula V = (2/3)πr³, where r is the radius of the hemisphere. Since the hemisphere has the same radius as the cone, i.e., r = 10 cm, we get:
V = (2/3)π(10 cm)³
V = 2093.33 cm³
The volume of the hemisphere is approximately 2093.33 cm³.
c) The volume of the entire figure is the sum of the volume of the cone and the volume of the hemisphere. Adding the volumes of the two shapes, we get:
V = 1570.8 cm³ + 2093.33 cm³
V = 3664.13 cm³
The volume of the entire figure is approximately 5759.6 cm³.

Step-by-step explanation:
Margo borrows $700, agreeing to pay it back with 3% annual interest after 17 months. How much interest will she pay? Round your answer to the nearest cent, if necessary.
To calculate the interest that Margo will pay, we first need to determine how much interest she will accrue over the 17-month period.
We can use the formula:
Interest = Principal x Rate x Time
Where:
Principal is the amount borrowed, which is $700 in this case.
Rate is the annual interest rate, which is 3% or 0.03 as a decimal.
Time is the time period expressed in years, which is 17/12 or 1.4167 years in this case (since there are 12 months in a year).
Therefore, the interest that Margo will pay can be calculated as:
Interest = $700 x 0.03 x 1.4167
Interest = $29.75
So Margo will pay $29.75 in interest. Rounded to the nearest cent, the answer is $29.8.

What is Average salary ?Average salary is the average amοunt οf mοney earned by wοrkers in a particular industry, ecοnοmy, area, etc.
Tοtal hοurs wοrked by Dοnοvan = 40 hοurs/week x 48 weeks/year = 1,920 hοurs/year
Next, we can calculate Dοnοvan's hοurly wage:
Hοurly wage οf Dοnοvan = Annual salary οf Dοnοvan / Tοtal hοurs wοrked by Dοnοvan
= $55,000 / 1,920 hοurs/year

Similarly, we can find the tοtal number οf hοurs that his brοther wοrks in a year:
Tοtal hοurs wοrked by Dοnοvan's brοther = 40 hοurs/week x 52 weeks/year = 2,080 hοurs/year
Hοurly wage οf Dοnοvan's brοther = Annual salary οf Dοnοvan's brοther / Tοtal hοurs wοrked by Dοnοvan's brοther
= $43,000 / 2,080 hοurs/year

two supplementary angles are such that the measure of one is twice the measure of the other find the angles
Answer:
60°
120°
Step-by-step explanation:
Supplementary angle are those that sum up to a total of 180 degrees.
So, let's have 2 angles, angle A and angle B.
Angle A's measure is α so the measure of angle B is 2α.
The sum of these two angles sum up to 180 degrees, so we can say that:
α + 2α = 180°
3α = 180°
α = 60°
So, one of our angles is 60° and the other is (2*60)° which is 120°.

Create an amortization table to answer the following:
a) What is the unpaid balance after 9 months? $
b) Over the 9 months in part (a), how much total interest did she pay?
Answer:
(a) After 9 months, the unpaid balance is $125,874.09.
(b) Over the 9 months, she paid a total of $4,918.56 in interest.
To create the amortization table, we can use the formula for calculating the monthly payment of a loan:
P = (r * A) / (1 - (1 + r)^(-n))
where:
P = monthly payment
r = monthly interest rate
A = loan amount
n = total number of payments
In this case, we have:
A = $128,000.00
n = 25 years * 12 months/year = 300 months
r = 5.3% / 12 = 0.00441666667
Using the formula, we can calculate the monthly payment:
P = (0.00441666667 * $128,000.00) / (1 - (1 + 0.00441666667)^(-300))
P = $770.82

The rectangular rug is similar to the rectangular floor. If the floor of the room measures 32 feet in length and 26 feet in width, what is the width of the rug?
The width of the rectangular rug is 13 feet and the length of the rectangular rug is 26 feet.
What is the step to calculate the area of the rectangle?Area of a rectangle formula: A = L * W. A
rectangle's length and width are multiplied to produce its area.
A is the area, L is the length, and W is the width or girth, where
A = L * W.
The corresponding sides of the rectangular rug and the rectangular floor must be proportional if they are alike.
Let's use "x" to represent the rug's width. The floor measures 32 feet in length and 26 feet in width, and the length of the rug is 16 feet according to the details provided. Since the rug and the surface are comparable, we can establish the following ratio:
Rug width/floor width = rug length/floor length
x / 26 = rug's length / 32
We can cross-multiply and then solve for "x" to find the answer:
32x = 26 * Rug's length
x = (26 * Rug Length) / 32
[tex]= \frac{26 * 16}{32} \\= \frac{26}{2} \\= 13[/tex]

How much would you be willing to pay today for an investment that would return $800 each year at the end of each of the next 6 years? Assume a discount rate of 4 percent.
Answer: Approximately $4,176.19 today for an investment that returns $800 each year for 6 years
Step-by-step explanation:
To calculate the present value of an investment that returns $800 each year for 6 years at a discount rate of 4 percent, we can use the formula for the present value of an annuity:
PV = C x [(1 - (1 / (1 + r)^n)) / r]
where PV is the present value, C is the annual cash flow, r is the discount rate, and n is the number of years.
Plugging in the given values, we get:
PV = 800 x [(1 - (1 / (1 + 0.04)^6)) / 0.04]
PV = $4,176.19 (rounded to the nearest cent)
Therefore, if the discount rate is 4 percent, you would be willing to pay approximately $4,176.19 today for an investment that returns $800 each year for 6 years

Which rectangle has the greater area, a rectangle with length 12 1 foot and width foot or a rectangle with length 16 foot and width foot?
Therefore, the second rectangle has a greater area than the first rectangle.
RectangleA rectangle is a quadrilateral geometric shape that has four sides and four right angles (90-degree angles). It is characterized by having opposite sides that are equal in length and parallel to each other. The rectangle's other two sides are also equal in length and parallel to each other but different in length than the opposite sides.
The area of a rectangle is calculated by multiplying its length by its width, which gives the total amount of space inside the shape. The perimeter of a rectangle is the sum of all its sides.
To find the area of a rectangle, we multiply its length by its width. Therefore, the area of the first rectangle is:
Area of first rectangle = 12 ft × 1 ft = 12 sq ft
And the area of the second rectangle is:
Area of second rectangle = 16 ft × 1 ft = 16 sq ft
Therefore, the second rectangle has a greater area than the first rectangle.

This shape is made up of one half-circle attached to a square with side lengths 17 inches. You can use 3.14 as an approximation for pie
The approximate perimeter of the entire shape is 77.69 inches.
How to find the perimeter of a figure?The perimeter of a figure is the sum of the whole sides of the figure.
Therefore, the perimeter of the entire shape can be calculated as follows:
The shape is made of three sides of a square and half a circle.
Therefore,
circumference of the semi circle [tex]= \pi r[/tex]
[tex]r = 17 \div 2 = 8.5 \ \text{inches}[/tex]
circumference of the semi circle [tex]= 8.5\pi[/tex]
Hence,
perimeter of the shape [tex]= 17+17+17+ 8.5\pi[/tex]
perimeter of the shape [tex]= 51 + 8.5(3.14)[/tex]
perimeter of the shape [tex]= 51 + 26.69[/tex]
Therefore,
perimeter of the shape = 77.69 inches
