Csc 0 = r/y
r = sqrt 81 + 144
r = sqrt 225
r = 15
csc 0 = 15/12

v=168
Step-by-step explanation:
Answer:
You can just add 1 every time, its just the fact that we dont know the wording of some things like i dont know what the correct wording to 6,000,000,000,000,000,000,000,000,000 is all i know is that its a number
Step-by-step explanation:
Answer:
-6
Step-by-step explanation:
Given that :
we are to evaluate the Riemann sum for
from 2 ≤ x ≤ 14
where the endpoints are included with six subintervals, taking the sample points to be the left endpoints.
The Riemann sum can be computed as follows:

where:

a = 2
b =14
n = 6
∴



Hence;

Here, we are using left end-points, then:

Replacing it into Riemann equation;






Estimating the integrals, we have :

= 6n - n(n+1)
replacing thevalue of n = 6 (i.e the sub interval number), we have:
= 6(6) - 6(6+1)
= 36 - 36 -6
= -6
The answer depends on whether you're looking for the x or the y. If y, the answers are the ones on the left, and the x on the right.
