The trigonometric function gives the ratio of different sides of a right-angle triangle. The measure of ∠C is 28°. And the value of b and c is 7.06 and 3.76, respectively.
<h3>What are Trigonometric functions?</h3>The trigonometric function gives the ratio of different sides of a right-angle triangle.
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.
The sum of all the angles can be written as,
∠A + ∠B + ∠C = 180°
90° + 62° + ∠C = 180°
∠C = 28°
Sin(∠B) = AC/BC
Sin(∠B) = b/8
b = 8 × Sin(62°)
b = 7.06
Cos(∠B) = AB/BC
Cos(∠B) = c/8
c = 8 × Cos(62°)
c = 3.76
Hence, the measure of ∠C is 28°. And the value of b and c is 7.06 and 3.76, respectively.

Answer:
.
Step-by-step explanation:
We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.
To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:
Therefore, the net profit for the year was .
Answer:
y = 4
Step-by-step explanation:
For an exponential function in standard form
y = a
To find the values of a and b, use ordered pairs from the table
Using (0, 4 ), then
4 = a (
= 1 ), so
a = 4
y = 4
Using (1, 8 ), then
8 = 4 = 4b ( divide both sides by 4 )
2 = b
Thus
y = 4 ← exponential function
