Answer:
Step-by-step explanation:
You mean to find side (hypotenuse) x and angles y and z in the right triangle.
We will find hypotenuse with Pythagorin theorem
x∧2 = 10∧2 + 8∧2 = 100 + 64 = 164 => x = √164 = 12.80
x = 12.80
According to the definition of tangens we have
tan y = 8/10 = 0.8 => y = arc tan 0.8 = 38.66° => y = 38° 39' 36''
tan z = 10/8 = 1.25 => z = arc tan 1.25 = 51.34° => z = 51° 20' 24''

Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
Answer:
The answer is 31.5
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 105 × 30/100
Discount = 105 x 0.3
You save = $31.50
Answer:
C.
Step-by-step explanation:
We have been given that Mike took out a $30,000 loan with a 7% annual interest rate. So the approximate amount, A(x), he has to pay on his loan at the end of each year as a function of x will be:
Using exponent property we will get,
Therefore, the equation represents the approximate amount, Mike has left to pay on his loan at the end of each year and option C is the correct choice.
