1:1 is the ratio of the length of one leg to the length of the other leg
Question 1:
For this case we must findknowing that:
By definition we have that, be two functions f (x) and g (x), then the composite function of f with g is:
In this case, they ask us for the function composed of g with f:
So, we have:
ANswer:
Question 2:
For this case, we must find the inverse function of , given by:
To do this, replace g(x) with y:
We exchange variables:
We solve for "y":
Replace "y" with
So, we have:
Answer:
Question 3:
For this case, we have by definition, the domain of a function f (x), is the set of all the values for which the function is defined.
We must find the domain of the following function:
It is observed that the function is not defined for
Then the domain is given by all the values of x, except 0.
for any integer n
Answer:
All numbers, except
<h3>
Answer: 4 feet</h3>
=======================================================
Work Shown:
See below for the diagram.
(person height)/(person shadow) = (tree height)/(tree shadow)
x/3 = 6/4.5
x*4.5 = 3*6
4.5x = 18
x = 18/4.5 ...... dividing both sides by 4.5
x = 4
The boy is 4 feet tall.
I believe it would be your first option
(18, 27) 3/4
Answer:$863.92
Step-by-step explanation:20% of 89.99 is 18
89.99x8=719.92
18×8=144
719.92+144=
863.92
