from the top of a 160-ft lighthouse, the angle of depression to a ship in the ocean is 26°. how far is the ship from the base of the lighthouse? (round your answer to the nearest foot.)

Answers

Answer 1

The distance between both the ship and the lighthouse's base is 328 feet.

What is considered as angle of depression?

If a line of sight is slightly down from the horizontal line, it forms an angle with the horizontal line. If the object being observed is below the observer's level, the angle formed between both the horizontal line and also the observer's lines of sight is known as the angle of depression.

Given the circumstances, a right angle triangle is constructed. The lighthouse's height represents the right angle triangle's opposite side.

The adjacent side of a right angle triangle is represented by the horizontal distance, h, between both the ship and thus the base of the lighthouse.

Because they are opposite angles, is if angle of depression to the fire is 26°, the angle of elevation of a lighthouse from the ship is also 26°.

To calculate h, we would use

the trigonometric tangent ratio;

Tan θ = opposite side/adjacent side. Therefore,

Tan 26 = 160/h

h = 160/tan26 = 160/0.4877

h = 328 feet

Therefore, the distance between the ship and the base of the light house is 328 feet.

This weekend, the local Cinema sold a total of 8500 movie tickets. The proceeds totaled $64,600. Tickets can be bought in one of 3 ways a matinee ticket costs $5 student tickets costs $6, and regular tickets are $8.50. How many of each type of ticket was sold if twice as many student tickets were sold as matinee tickets?​

Answers

Number of matinee tickets = 900

Number of student tickets = 1800

Number of regular tickets = 5800

Algebra is the branch of mathematics that represents problems and situations in the form of mathematical expressions. It contains variables such as x, y, z, and operations such as addition, subtraction, multiplication, and division to form  meaningful mathematical expressions.

Algebra is used mostly in all areas of mathematics like trigonometry, calculus, and coordinate geometry. A simple example of an algebraic expression  is 9x + 4 = 8.

Algebra deals with symbols, and these symbols are related to each other by operators. It's not just a mathematical concept, it's a skill that we all use subconsciously in our daily lives.

Let x be the number of matinee tickets.

In that case, the number of  student tickets is 2x.

The number of regular  tickets is (8500-x-2x) = (8500-3x).

Total money

5x + 6*(2x) + 8.50*(8500-3x) = 64600

Simplifying and solving for x

5x + 12x - 8.50*3*x + 8.50*8500  = 64600

5x + 12x - 8.50*3*x = 64600 - 8.50*8500

Solving x , we get

x = 900

Number of matinee tickets = 900

Number of student tickets = 1800

Number of regular tickets = 8500 - (900+1800) = 5800

Answers

The total value of the furniture she sold is $4400.

How to compute the value?

Let the remaining sales be represented by x.

She receives 10% of her first $900 in sales and 15% of the balance of her sale.

This will be:

(10% × $900) + (15% × x) = 750

90 + 0.15x = 750

Collect like terms

0.15x = 750 - 90

0.15x = 660

Divide

x = 660/0.15

x = 4400

Therefore, the total value is $4400.

How many gallons of 35% solution is needed by Eli ?

Generally, It takes 0.125 gallons of a 35% solution to get the ratio you want.

Eli wishes to mix 0.5 gallons of a 10% acetic acid solution with a 35% solution to create a 15% acetic acid solution; thus, the calculation below must be done to calculate how many gallons of

5% solutions are required:

1 x 10 + 2 x 35 = 80

=> 80 ÷ 3 = 26.66

1x10 + 1x35 = 45

=>45÷ 2 = 2.5

1 x 10 + 0.5 x 35 = 27.5

=>27.5 ÷ 1.5 = 18.33

1 x 10 + 0.4 x 35 = 24

=>24 ÷ 1.4 = 17.14

1 x 10 + 0.2 x 35 =17

=> 17 / 1.2 = 14.16

1 x 10 + 0.3 x 35 = 20.5

=> 20.5/ 1.3 = 15.76

1 x 10 + 0.25 x 35 = 18.75

=> 18.75 / 1.25 = 15

1 / 2 = 0.5

0.25 / 2 = 0.125

a piece of wire 100 inches long is cut into two pieces and each bent into the shape of a square. if the sum of the areas of the two squares is 400 in2, find the length of each piece of wire.

Answers

The length of the pieces of wire include 23.5425 inches and 75.4565 inches.

How to calculate the length?

Given the total length of wire is

X+Y=100

Y=100-X

Then we bend the two pieces into squares so that the sides of each square are X/4 and (100-X)/4. Therefore

(X/4)² + [(100-X)/4]² =400

X² +10000-200X +X² =6400

X²-100X+1800=0

Solving the equation

X = 76.4565 inches and X=23.5425 inches

Therefore, the length of the pieces of wire include 23.5425 inches and 75.4565 inches.

graph the equation y= 2/3x+5

Answers

the equation formula y=2/3x+5 is (3,-3).

In mathematics, what is an equation?

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

based on the available facts;

You might be wondering how, but we can start with that 5 at the end, which denotes the y-intercept.

If 0 is used in place of x, then y=2/30+5y=5

We shall receive the first coordinate as a result, which is (0,5).

Let's then consider the slope, which is 2,3. As you may already be aware, the slope is also known as

rise/run

; what do they mean by that is that the first top number tells you how many units you go up and the second one how many units you go right or how many units you go down and go left.

Now, I know this may seem complicated but let's make it clear. Since we know one coordinate, which is

(0,5)

, from that point by knowing the slope we can find a second point; this point is 2 points above and 3 to the right, which tells us that −5+2

points above gives us −3 and 3 points on the right gives us a new coordinate:

(3,−3)

And since we now know two coordinates, that is enough to draw the line and have the graph.

Hence, the equation of exponential function is represented by y = A(Bˣ)

An exponential function is a mathematical function of the form f(x) = ax, where "x" is a variable and "a" is a constant  called the base of the function and it must be greater than 0.

The most commonly used exponential basis is the transcendental number e, which is approximately equal to 2.71828

The equation in exponential form

y = A(Bˣ)

Case 1 :

x =0 y = 0.02

0.02 =  A (B⁰)

A = 0.02

Case 2:

x = 1 y =0.04

0.04 =  0.02(B)

0.04 /0.02 = B

B = 2

Case 3 :

x = 2 y =0.08

0.08 = 0.02(2²)

0.08 = 0.08

Case 4 :

x = 3 y = 0.16

0.16 = 0.02(2³)

0.16 = 0.16

So, we have implemented the eqaution y = A(Bˣ)

Find the coordinates of the centroid of the triangle with the given vertices. (Lesson 5-2)
U(-5,5), K(-5,-1), L(1,2)

Answers

The triangle with vertices located at U(-5 , 5), K(-5 , -1), and L(1 , 2) has its centroid located at (-3 , 2).

The centroid of a triangle is the point inside the triangle where the three medians intersect. The median of a triangle is the line the connects the midpoint of a side and the opposite vertex.

To get the centroid of a triangle, use the formula given by:

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

where C is the centroid of the triangle located at (x , y)

x1, x2, and x3 are the x-coordinate of the vertices of the triangle

y1, y2, and y3 are the y-coordinate of the vertices of the triangle

Let Point 1(x1 , y1) = U(-5 , 5)

Point 2(x2 , y2) = K(-5 , -1)

Point 3(x3 , y3) = L(1 , 2)

Plug in the values in the formula.

C(x , y) = [(x1 + x2 + x3)/3 , (y1 + y2 + y3)/3]

C(x ,y) = [(-5 + -5 + 1)/3 , (5 + -1 + 2)/3]
