We're given that and , and want to find .
By the chain rule, we have
and
Then
(because the point corresponds to )
Let the no. of stars one can expect to see at Bryce Canyon be x.
Given that : No. of stars visible in the night sky = 2000
Also, given that, it is 4/15 of x.
Now, we have
∴ You can expect to see 7,500 stars at Bryce Canyon.
5/8=x/100
x=(5/8)(100)=500/8
x=62.5%
we are given
we can write it in terms of exponents
Firstly , we will simplify numerator
now, we can add exponents
we can cancel it
and we get
