sin^2x-0,5sin2x=0
Answers
This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .

Step-by-step explanation:
salary per year=1200×12=14400
let the sale be $ x
14400+38 % of x=35,000
38 % of x=35,000-14,400=20,600
x=20,600 \times \frac{100}{38}=$ 54210.53
Final answer:
To earn $35,000 per year, the sales rep must generate approximately 54,210 sales.
Explanation:
To find out how many sales the wholesale food sales rep must generate in order to earn $35,000 per year in total compensation, we need to set up an equation based on the given information. Let's assume the sales generated by the rep are 'x'. The total compensation can be calculated as:
Total Compensation = Base Salary + Commission
$35,000 = $1200/month + 0.38x
Now, we can solve this equation to find 'x', the number of sales needed. First, let's convert the monthly base salary to yearly:
$1200/month * 12 months = $14,400/year
Substituting this value into the equation:
$35,000 = $14,400 + 0.38x
Now, we can isolate 'x' by subtracting $14,400 from both sides of the equation:
$20,600 = 0.38x
Finally, divide both sides of the equation by 0.38:
x = $20,600 / 0.38 = 54,210
Therefore, the wholesale food sales rep must generate approximately 54,210 sales in order to earn $35,000 per year in total compensation.

The statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.
To determine if the statement is true or false we need to know what radiactivity is
What is radioactivity?
Radioactivity is the spontaneous disintegration of unstable atomic nuclei to form stable more energetic nuclei with the emission of radiation.
Radioactivity includes the following
- disintegration of a larger atomic nuclei to a smaller more stable nuclei
- Emission of radiation
So, radioactive nuclei which are unstable emit radiation and become more stable.
So, the statement radioactive nuclei are highly stable and emit radiation to become unstable is FALSE.

So, about 18 inches.
Or 17.93in with significant digits.
To break it down, you can set up your information as a fraction (which I did for the first fraction.) Then you want your units to cancel out, so I put the 7.489 minutes on the top of the next fraction and multiplied them. The min canceled out and left me with in, so I know I had the correct answer.
