Answer:

A) sin θ = 3/5

B) tan θ = 3/4

C) csc θ = 5/3

D) sec θ = 5/4

E) cot θ = 4/3

Step-by-step explanation:

We are told that cos θ = 4/5

That θ is the acute angle of a right angle triangle.

To find the remaining trigonometric functions for angle θ, we need to find the 3rd side of the triangle.

Now, the identity cos θ means adjacent/hypotenuse.

Thus, adjacent side = 4

Hypotenuse = 5

Using pythagoras theorem, we can find the third side which is called opposite;

Opposite = √(5² - 4²)

Opposite = √(25 - 16)

Opposite = √9

Opposite = 3

A) sin θ

Trigonometric ratio for sin θ is opposite/hypotenuse. Thus;

sin θ = 3/5

B) tan θ

Trigonometric ratio for tan θ is opposite/adjacent. Thus;

tan θ = 3/4

C) csc θ

Trigonometric ratio for csc θ is 1/sin θ. Thus;

csc θ = 1/(3/5)

csc θ = 5/3

D) sec θ

Trigonometric ratio for sec θ is 1/cos θ. Thus;

sec θ = 1/(4/5)

sec θ = 5/4

E) cot θ

Trigonometric ratio for cot θ is 1/tan θ. Thus;

cot θ = 1/(3/4)

cot θ = 4/3

The actual distance between parks is 24 miles On a map these parks are 8 inches apart How many miles are equal to one inch on th
vaieri [72.5K]

Each inch in the map is equivalent to 8 miles.

Explanation:

There is a distance of 24 miles between two parks. This 24 miles is represented by an 8-inch gap in the map.

So 8 inches on that particular map = 24 miles in real life.

To find the distance that an inch on the map represents we must divide both sides of the above equation. Since we need to calculate how much distance 1 inch represents we divide both the sides by 8 so that 8 inches on the map changes into 1 inch.

\frac{8}{8} inches on the map = \frac{24}{8} miles between the two parks in real life,

1 inch on that particular map = 3 miles in real life.

So each inch on the given map is equal to 8 miles in real life.

What is the vertex of the parabola with the equation y=1/5x^2 + 2x - 8
bixtya [17]

Answer:

(-5,-13)

Step-by-step explanation:

Find the vertex of the parabola y=1/5x^2+2x−8.  

In this equation a=15  and b = 2.  

x= -2/2(1/5) = -2/2/5 = -2/1 * 5/2 = -5

Substitute −5 into the equation y=1/5x^2+2x−8

y=1/5(−5)^2+2(−5)−8

y=5−10−8

y=−13

The vertex is (−5 , −13)

X-3y=-24<br> 5x+8y=-5<br><br> this equation is substitution, need help :))
Leto [7]

Answer:

x=-9, y=5. (-9, 5).

Step-by-step explanation:

x-3y=-24

5x+8y=-5

--------------

x=-24+3y

5(-24+3y)+8y=-5

-120+15y+8y=-5

-120+23y=-5

23y=-5-(-120)

23y=-5+120

23y=115

y=115/23

y=5

x-3(5)=-24

x-15=-24

x=-24+15

x=-9
