Trigonometric Ratios

The ratios of the sides of a right triangle are called trigonometric ratios. There are six trigonometric ratios, sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot).

The ratios are valid only in right triangles, or when one of the internal angles is 90°.

Take any of the acute angles as a reference, and the largest side as the hypotenuse, then:

[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle csc\theta=\frac{\text{hypotenuse}}{\text{opposite leg}}[/tex]

[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

The missing side of the triangle x can be calculated by using Pythagora's Theorem:

[tex]10^2=9^2+x^2[/tex]

Solving:

[tex]x^2=10^2-9^2=100-81=19[/tex]

[tex]x=\sqrt{19}[/tex]

For the angle marked as θ:

[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]

[tex]\displaystyle \tan\theta=\frac{\text{9}}{\sqrt{19}}[/tex]

Rationalizing:

[tex]\displaystyle \tan\theta=\frac{9\sqrt{19}}{19}[/tex]

[tex]\displaystyle \cos\theta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

[tex]\displaystyle \cos\theta=\frac{\sqrt{19} }{10}[/tex]

[tex]\displaystyle \csc\theta=\frac{\text{hypotenuse}}{\text{opposite leg}}[/tex]

[tex]\displaystyle \csc\theta=\frac{10}{9}[/tex]

A circular oil spill in the ocean is increasing in diameter at a rate of 200 feet per hour. By how many square feet is the oil spill increasing per hour?
Increase in diameter: d(h) = 200h; h in hours
Increase in area: A(d) = π(0.5d)2; d in feet
Which composite function represents the total area of the oil spill as a function of hours?

Answers

Answer:

A(d(h)) = π(100h)2

Step-by-step explanation:

In edge it would be C

When solving these word problems it is helpful to remember that they ask us to use composition of functions to solve it so if it is the total area in regards to hours, what you would need to do look at the problem in this manner:  

A( (d(h) )= A (Pi(0.5x200h)^2

and when you simplify like terms it would be:

Pi(100h)^2

A car can travel 135 miles with 5 gallons of gasoline. At this rate, how much gallons of gasoline the car needs to travel 675 miles?

Answers

Answer:

25 gallons

Step-by-step explanation:

Given

135 miles to 5 gallons

Required

Determine the number of gallons for 675 miles

From the question, number of miles is directly proportional to number of gallons:

So, we have:

[tex]135\ miles = 5\ gallons[/tex]

and

[tex]675\ miles = x[/tex]

Where x represents the number of gallons for 675 miles

Cross Multiply:

[tex]135 * x = 675 * 5[/tex]

[tex]135x = 3375[/tex]

Make x the subject

[tex]x = 3375/135[/tex]

[tex]x = 25[/tex]

Hence, the car needs 25 gallons

The area of a trapezoid is 864cm². It has a height of 24 cm, and the length of one of its bases is 30 cm. What is the length of the other base?​

Answers

The area A of a trapezoid with height h and bases b₁ and b₂ is equal to the average of the bases times the height:

A = (b₁ + b₂) h / 2

We're given A = 864, h = 24, and one of the bases has length 30, so

864 = (b₁ + 30) 24 / 2

864 = (b₁ + 30) 12

864 = (b₁ + 30) 12

72 = b₁ + 30

b₁ = 42

What is the formula for the area of a square?

Answers

Answer:

Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in2.)

add (5y - 1)+ (-2y + 4)​

Answers

Answer:

3y+3

Step-by-step explanation:

"Simplifying

(5y + -1) + (-2y + 4) = 0

Reorder the terms:

(-1 + 5y) + (-2y + 4) = 0

Remove parenthesis around (-1 + 5y)

-1 + 5y + (-2y + 4) = 0

Reorder the terms:

-1 + 5y + (4 + -2y) = 0

Remove parenthesis around (4 + -2y)

-1 + 5y + 4 + -2y = 0

Reorder the terms:

-1 + 4 + 5y + -2y = 0

Combine like terms: -1 + 4 = 3

3 + 5y + -2y = 0

Combine like terms: 5y + -2y = 3y

3 + 3y = 0

Solving

3 + 3y = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 3y = 0 + -3

Combine like terms: 3 + -3 = 0

0 + 3y = 0 + -3

3y = 0 + -3

Combine like terms: 0 + -3 = -3

3y = -3

Divide each side by '3'.

y = -1

Simplifying

y = -1 "

What is isosceles triangle?

An isosceles triangle is a triangle which is having two sides equal to each other.

How to determine angles?

Firsty we have to find the value of x in the angles. We have been given that the triangle is isosceles because two sides are equal to each other and we know that angles opposite to two equal sides are also equal to each other.

So,

(4x+16)°+2(5x+7)°=180°

4x-16+10x+14=180

14x-2=180

14x=180+2

14x=182

x=182/14

x=13

Putting the value of x.

∠BCA=5x+7

=5*13+7

=65+7

=72

∠ABC=4x-16

=4*13-16

=52-16

=36

∠BAC=180-36-72

=180-108

=72

∠BCD=180-∠BCA

=180-72

=108°

Hence the correst angle measures in the triangle ABC is that m∠BAC=72° and ∠BCD=108°.

You and 5 friends are in a math club. A sponsor pays $75 to rent a bus to get to competition, a $100 entry fee for the team, and D dollars for each students t-shirt. Write an expression for the total amount the sponsor paid.

Answers

Answer:

Total amount paid by the sponsor = 175 + 6d

Step-by-step explanation:

You and 5 friends = 6 people

Cost of renting a bus = $75

Team entry fee = $100

Cost of each student t shirts = $d

Cost of 6 student t shirts = $d × 6

= $6d

Write an expression for the total amount the sponsor paid.

Total amount paid by the sponsor = Cost of renting a bus + Team entry fee + Cost of 6 student t shirts

= $75 + $100 + $6d

= $175 + $6d

Total amount paid by the sponsor = 175 + 6d

Where,

d = cost of each student t shirts

The altitude (i.e., height) of a triangle is increasing at a rate of 1.5 cm/minute while the area of the triangle is increasing at a rate of 3.5 square cm/minute. At what rate is the base of the triangle changing when the altitude is 10 centimeters and the area is 86 square centimeters? The base is changing at cm/min.

Answers

Answer:

-1.88cm/min

Step-by-step explanation:

Given

dh/dt = 1.5cm/min

dA/dt = 3.5cm²/min

Height h = 10cm

Area A = 86cm²

Required

db/dt

b is the base

h is the height.

Area of a triangle A = 1/2bh

dA/dt = dA/db•db/dt + dA/dh •dh/dt

dA/db = h/2 = 10/2 = 5cm

Get the base

86 = 1/2(10)b

5b = 86

b = 17.2cm

dA/ dh = 1/2b = 1/2(17.2)

dA/dh = 8.6cm

.substitute given values into the formula above;

dA/dt = dA/db•db/dt + dA/dh •dh/dt

3.5 = 5 db/dt + 8.6(1.5)

3.5 = 5 db/dt + 12.9

5 db/dt = 3.5-12.9

5 db/dt = -9.4

db/dt = -9.4/5

db/dt = -1.88cm/min

Hence the base is changing at -1.88cm/min
