the question: “which trig. ratio woild you use to find the missing side?”

Answers

Answer:

Step-by-step explanation:

It's not the tangent. The tangent relates two sides neither of which is the hypotenuse, which you are given.

The trig ratio you would use is the one that  relates the angle to the side opposite the angle and the hypotenuse.

That is the definition for the Sine.

Adult tickets for the school musical are sold for $3.50 and student tickets are sold for $2.50 on a given night 425 tickets were sold for $ 1237.50. Wrote a system of linear equations for the problem

Answers

Answer:

3.5x + 2.50y = 1237.50

425 = x + y

Step-by-step explanation:

number of adult tickets: x

number of student tickets: y

3.5x + 2.50y = 1237.50

( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)

425 = x + y

(number of adult tickets [x]) + (number of student tickets [y]) = total (425)

An object is moving east, and it’s velocity changes from 65 m/s to 25 m/s in 10 seconds.which describes acceleration

Answers

Answer:

The acceleration of object is -4 ms⁻²

Step-by-step explanation:

We are given:

Initial Velocity = 65 m/s

Final Velocity = 25 m/s

Time t = 10 seconds

We need to find acceleration.

The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]

Putting value in the formula and finding acceleration:

[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]

So, acceleration of object is -4 ms⁻²
