Given:
Cost of one pound of apples = $1.98
To find:
The cost of 0.75 pound of apples.
Solution:
We have,
Cost of one pound = $1.98
So, cost of 0.75 pound of apples = 0.75 × cost of one pound of apples
Therefore, the cost of 0.75 pound of apples is $1.485.
Answer:
First, we know that:
cot(x) = cos(x)/sin(x)
csc(x) = 1/sin(x)
I can't know for sure what is the exact equation, so I will assume two cases.
The first case is if the equation is:
if we replace cot(x) and csc(x) we get:
Now let's we can rewrite this as:
We can't simplify it more.
Second case:
If the initial equation was
Then if we replace cot(x) and csc(x)
This is equal to:
And we know that:
sin^2(x) + cos^2(x) = 1
Then:
sin^2(x) - 1 = -cos^2(x)
So we can replace that in our equation:
