Answer:
x = 19.5 ( to the nearest tenth )
Step-by-step explanation:
Since the triangle is right, we can use the cosine ratio to find x
cos46° = =
multiply both sides by 28
x = 28 × cos46° = 19.450 ≈ 19.5
Solution:
It is given that , number of members f(x) in Joe's health club increased by 25% every year over a period of x years.
The relationship between f(x) and x is given as:
Replacing f(x) by y, in the above equation
y=
To draw the graph without the help of Desmos, find diifferent value of y, for different values of x, For example , for x=1
We get , y= = 18.75
For, x=2
y= =15 × 1.5625=23.4375
For, x=3
y= = 29.296875
So, for different values of x, we get different values of y. Mark these points in the coordinate plane, and join them . You will get the graph of the above function :⇒ f(x)=
Graph is depicted below.
