Answer: 5
Step-by-step explanation:
f(x)=3-x
f(-2)=3-(-2)
f(-2)=3+2
f(-2)=5
Hope this helps!! :)

9 x 4 = 12 this the answer
Answer:
x ≈ 42.3
Step-by-step explanation:
The law of cosines is given. For this problem, ...
a = 25, b = 30, c = x , C = 100°
Filling in these values, we have ...
x^2 = 25^2 +30^2 -2(25)(30)cos(100°)
x^2 ≈ 1785.4723
x ≈ √1785.4723 . . . . take the square root
x ≈ 42.3
The formula for simple interest is the following:
In this formula, 
is the amount of interest, 
is the principal (or initial) amount, 
is the interest rate, and 
is the length f time, typically in years.
First, let's make a couple of changes to how we wrote down the variables.
- Change the interest rate,
, to the decimal value 
. - Convert the length of time to years. 180 days divided by 360 days per year equals
years.
Substitute in the values and solve with a calculator.
Our Order of Operations looks like this:
Parenthesis
Exponent
Multiplication/Division
Addition/Subtraction
Multiplication and division are on the same "level".
When we see them in the problem, we execute the operations from LEFT TO RIGHT. So Shawna should have applied the division before multiplying the 2 and 3. (Because the division is the leftmost operation in the problem).
