Answer:
7.1
Step-by-step explanation:
We used SOHCAHTOA because it's a right angle triangle
So because we have an angle with an adjacent of 6.3 and hypotenuse of x
We will use
Cos=adjacent /hypotenuse
Answer: Order from Least to Greatest
2/6 < 4/10 < 5/12 < 3/7
Step-by-step explanation:
Answer:
x + 3 / 2 = y
Step-by-step explanation:
to change a function to its inverse we need to do three basic things
1. change f(x) to y
so for the example i gave which is f(x) = 2x - 3; this will now be
y = 2x - 3
2. we need to switch the position of the x's and y's, that means x becomes y and y becomes x
x = 2y - 3
3. finally we make y the subject of the formula
x + 3/ 2 = y, this new expression for y is the inverse of the function and can be written as
f^-1(x) = x + 3/2
Answer:
B. f(x) domain: x ≥ 1; f⁻¹(x) range: y ≥ 1
Step-by-step explanation:
The <em>domain</em> of a function is identical to the <em>range</em> of its inverse. This is reflected in choices B and D. However, f(x) is undefined for x < 1, so it makes no sense to restrict its domain to x ≤ -2, as in choice D.
The appropriate response is ...
B.
- f(x) domain: x ≥ 1
- f⁻¹(x) range: y ≥ 1
