Hello!</h2>
The asnwer is: Cos50° ≈ 0.643
<h2>
Why?</h2>
A unit circle is a cirgle with a radius equal of 1, knowing that, also know the following:
The angle is drawn passing trough the unit circle at (0.643,0.766) it means that:
So,
Cos50° ≈ 0.643
We can prove that by following the next steps:
- If it's a unit circle,here is a right triangle with hypotenuse of 1,
- We can determine the cosine of the angle by the following formula:
Therefore,
Cos(α)=49.98°≈50°
Also, if there is a right triangle, according to the Pythagorean Thorem:
Hence,
Cos50° ≈ 0.643
Have a nice day!
Answer:
-3
Step-by-step explanation:
Note the parts of the equation:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
In this case: y = 4x - 3
x = x
y = y
m = slope = 4
b = y-intercept = -3

Answer:
Point A
Convert fraction into decimal =0.15
1 is a whole number, which would make the fraction a mixed fraction, and the 5 is the tenths place, so its 1 5/10
Since you provide no information about the median salary, i'm gonna use the national data, whcih is around $ 13,000 per year
Cost of education for 2 year = $30,000
Since he's still working in those 2 years, he'll earn = $ 26,000
Which means he just need to work for around half a year to cover the remaining $4,000 , so i think the answer is 2.5 years
hope this helps
