Find the reference angle of the following angles:

Mathematics
1 answer:
nadya68 [22]3 years ago
5 0

Answer:

7π/18 radians

Step-by-step explanation:

A reference angle for angle β is the positive acute angle made by the terminal side of angle β and the x-axis.

A semi-circle angle has a measure of π radians.

The angle of the figure (in absolute value) can be decomposed as the addition of its reference angle and π radians. Therefore:

π + reference angle  = 25π/18

reference angle  = 25π/18 - π

reference angle  = 7π/18 radians

5. The scale of a map says that 8 cm represents 5 km.
sleet_krkn [62]

Answer:

a. 12.8 cm    b. 3.125

Step-by-step explanation:

To find any scale drawing use a proportion with one unit of values on the top and the other on the bottom. For example 8cm/5km = x/8km. So you would multiply 8 cm and 8 km and then divide by 5 to get 12.8 cm. For the second question plug in 5m in the numerator and solve for its denominator.

PLS HELP ASAP!! WILL MARK BRAINLYIST

Answer:

$39,851.25

Step-by-step explanation:

If the sales increase at a rate of 9% per year, this means it will be 109% of the previous year's value since 100% + 9% = 109%

109% in decimal form = 109/100 = 1.09

Therefore, the exponential function is:

y = 20000 \cdot 1.09^x, where x is the number of years

So when x=8,  

y = 20000 \cdot 1.09^8=39851.252...

After 8 years, annual sales = $39,851.25
