Answer:
5
Step-by-step explanation:
I'm going to assume the expression is (r)(s) + 14s
In order to evaluate this expression We'll need to input the values of r and s into the expression.
(6)(1/4) + 14(1/4)
(6/4) + (14/4)
20/4

Answer:
r = 9/sin Ф or r = 9 csc Ф
Step-by-step explanation:
The polar form is represented as:
x = r cos Ф and
y = r sin Ф
We are given:
y = 9
Putting value in y = r sin Ф
9 = r sin Ф
=> r = 9/sin Ф
1/sin Ф = csc Ф
or, r = 9 csc Ф
