________is an acute angle and sin theta and cos theta are given. Use identities to find tangent theta, cosecant theta, secant th

AnnyKZ [126]

Answer:

tangent theta = 12/5,

cosecant theta = 13/12

secant theta = 13/5

Cotangent theta = 5/12

Step-by-step explanation:

Given sine theta= 12/13, cosine theta= 5/13.

According to SOH CAH TOA

Sintheta = Opposite/Hypotenuse = 12/13

Cosine theta = Adjacent/Hypotenuse = 5/13

Opposite = 12, Adjacent = 5, Hypotenuse = 13

Tan theta = Opposite/Adjacent = 12/5.

cosecant theta = 1/sintheta = 1/{12/13}

cosecant theta = 13/12

secant theta = 1/cos theta = 1/{5/13}

Secant theta = 13/5.

Cotangent theta = 1/tan theta = 1/{12/5} = 5/12

A man bought a horse and carriage for $500 paying three times as much for the carriage as for the horse how much did each cost

Lorico [155]

Hello! So, in order to solve this question, we should do 500/4. 500/4 = 125. Multiply 125 by 3 and you get 375. The horse costs $125 and the carriage costs $375.

The country recreation department cleared a 3/4 mile long walking trail in Washington Park. There will be a small sign every 1/1

dem82 [27]

We are given " The country recreation department cleared a 3/4 mile long walking trail in Washington Park."

Therefore total distance = 3/4 miles.

"There will be a small sign every 1/12 mile along the trail, including at the beginning and end of the trail. "

Distance of small sign = 1/12 mile.

We need to find the number of signs in 3/4 miles each of 1/12 miles.

In order to find the number of signs, we need to divide total distance by distance of a small sign.

3/4 ÷ 1/12

= 3/4 × 12/1 = 3 × 3

= 9 signs.

<h3>Therefore, 9 signs are needed.</h3>

Using elimination method

bogdanovich [222]

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

<h3>Given;</h3>

-7x + y = – 19
-2x + 3y = – 19

The value of x and y

<h3>By Using Elimination Method;</h3>

First name the equation

-7x + y = – 19 ...(1)
-2x + 3y = – 19 ...(2)

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

+ – +

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

<h3>For Verification;</h3>

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Here, L.H.S = R.H.S

Hence Verified!
