Out of the given choices, the phrase that best describes a nonlinear function is letter A. The area of a circle as a function of the radius. This is because area is calculated through the equation,
A = πr²
All the rest of the choices presents linear functions.
Take the original price and multiply it by 30% (0.3). Take that answer and subtract it from 18 dollars.
5/18 as a decimal:
This is quite simply to solve. The easiest way to find the decimal of an improper fraction is to divide the numerator (5) by the denominator (18). 5 ÷ 18 would be our problem. The solution can be found on a calculator or doing long division. 5 ÷ 18 = 0.2777.
Answer:
Answer:
30.7
Step-by-step explanation:
Recall: SOH CAH TOA
We are to solve for the missing side
First, label the sides:
Reference angle (θ) = 61°
x = Opposite (this is opposite to the reference angle)
17 = Adjacent
Hypotenuse = side opposite to right angle
Apply TOA, which is:
Tan θ = Opp/Adj
Plug in the values
Tan 61° = x/17
17*Tan 61° = x
30.6688118 = x
x ≈ 30.7 (approximated to nearest tenth)

4x = 92
Solving
4x = 92
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x = 23
Simplifying
x = 23</span>
