You have the opposite and the hypotenuse given. So you use the sine ratio
Sin x = 6/9
x= sin inverse of 6/9 = 41.8 degrees
Answer:
x = ±2√15
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
x² = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Square root both sides: x = ±√60
- Simplify: x = ±2√15
<u>Step 3: Check</u>
<em>Plug in both solutions of x to verify it's a solution.</em>
x = 2√15
- Substitute: (2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
x = -2√15
- Substitute: (-2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
Here we see that both solutions do indeed work.
∴ x = ±2√15 are both solutions to the equation.
To get a certain percentage as a decimal, all you have to do is divide this percentage by 100.
Applying this on the given question, we will find that:
3.58% = (3.58) / (100) = 0.0358
Comparing the calculated value to the given choices, we will find that the correct choice is:
<span>c) 0.0358</span>
Multiplying a vector 
by a constant 
gives you a new vector whose components are the same as , but scaled by :
So we have
Vector addition is just a matter of adding the corresponding components together:
Then
denotes the norm/magnitude of the vector :
We have
