Answer:

23.6

Step-by-step explanation:

Hello There!

So they want us to find ∠Z

We are given ∠Zs opposite side length and the length of the hypotenuse

Sine refers to opposite divided by hypotenuse

So we can use sine to solve for ∠Z

SinZ=\frac{6}{15} \\\frac{6}{15} =.4\\SinZ=.4\\Z=arcsin(.4)\\Z=23.57817848

Note: arcsin is the inverse of sin

Other way we could find ∠Z:

We could also use law of sines which states that a side length divided by sin(its opposite angle) is equal to a different side length divided by sin ( its opposite angle)

So specifically for this triangle

\frac{15}{sin90} =\frac{6}{sinZ}

step 1 multiply each side by 6

note : flip the fraction

\frac{6sin90}{15} =sinZ\\\frac{6sin90}{15}=.4\\.4=sinZ\\arcin(.4)=23.57817848\\Z=23.57817848

Then our final step is to give our answer to the first decimal place

so the answer would be 23.6

How can the order of operations be used to simplify expressions?
Lapatulllka [165]
Order of Operations, also known as PEMDAS (Parentheses, Exponents, Multiplication & Division, Addition & Subtraction), can help to simplify an equation by guiding you through the steps to solve it.

This is because it tells you to solve the parentheses. If there is none, but you've already done this, you solve for exponents, etc. 

The progressive soling of the equation not only makes it physically shorter, but also brings you closer to the answer.

Hope this helps, and I was the brainliest! :)

Which recursive formula can be used to determine the total amount of money earned for each successive hour worked based on the a
sveticcg [70]

Complete question is;

An electrician earns $110 after his first hour of working for a client. His total pay based on the number of hours worked can be represented using the sequence shown.

110, 130, 150, 170, ...

Which recursive formula can be used to determine the total amount of money earned for each successive hour worked based on the amount of money currently earned?

Answer:

The recursive formula can be expressed as; f(x + 1) = f(x) + 20

Step-by-step explanation:

Electrician earns $110 dollars after working for 1 hour.

We were told his total pay based on number of hours worked can be represented by: 110, 130, 150, 170...

This means that writing it down as a function, we can say;

f(1) = $110, f(2) = $130 e.t.c

Now,since we want to express a recursive formula to explain the question, then let's say after the 1 hour worked, he earned $110, then the hour after that, his total is $130,then the hour after that, his total is $150.

This means that he earns an additional $20 each hour.

Thus;

f(x + 1) = f(x) + 20

Where x is number of hours and f(x) is payment after x number of hours

The recursive formula can be expressed as; f(x + 1) = f(x) + 20
