Answer:
35) A. 21.2
46) D. 4/7
30) B. 4.4
42) C. Prism
Step-by-step explanation:
35) see first two attached files. 134.3 - 113.1 = 21.2
46) see third attached file. 4/7 = .5714 ish and 112 pi = 351.59 ish
30) see fourth attached file.
42) prisms are in no way circular so it cant have a circular base when cut
Already did this but may as well get the points haha
Answer:
I think this is the right answer but last two signs are incorrect
Hope this will help
Well first, you solve for C.
Step 1: Get C by itself.
C + 2/45 = 8/5
*Subtract "C" to both sides.
C + 2/45 = 8/5
-C -C
The problem now becomes 2/45 = 8/5c
Step 2: Divide 8/5 to both sides.
2/45 = 8/5c
-8/5
Step 3: Divide your fractions by doing reciprocal.
2/45 / 8/5
2/45 * 5/8
2 5
* = 10/360
45 8
10/360 can be simplified to 5/72
C = 5/72.
Answer:
cot theta = -√3
Step-by-step explanation:
we are given that cos theta = - √3/2 within the range 180° < theta < 270° and
since cos theta = adj/hyp
adj = - √3
hyp = 2
Get the opposite using the pythagoras theorem
hyp^2 = opp^2 + adj^2
2² = opp² + (-√3)²
4 = opp² + 3
opp² = 4-3
opp² = 1
opp = 1
tan theta = opp/adj
tan theta = - 1/√3
Recall that cot theta = 1/tan theta
cot theta = 1/(-1/√3)
cot theta = -√3
