False because you can subtract your way out of the set of whole numbers
Answer:
Inverse function is 
.
Step-by-step explanation:
Given function is 
.
Now we need to find the inverse of the given function.
Step 1: replace f(x) with y
Step 2: switch x and y
Step 3: solve for y
Hence required inverse function is .
Answer:
The imaginary part is: z = 19
Step-by-step explanation:
For real numbers a and b, a number written in form a+bi is called a acomplex number. The value a is called the real part and b is called the imaginary part of complex number.
Answer:
5,888.67
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
9^2 + x^2 = 15^2
81 + x^2 = 225
Subtract 81 from each side
x^2 =225-81
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x=12
