Please Help! Find the exact value: csec 22pi/3

Mathematics
1 answer:
Cloud [144]4 years ago
6 0
Is this csec as in cosecant? If so, that would be csc 22pi/3. Through trigonometric identities, csc is just the inverse of sin. So it is equivalent to 1/sin(22pi/3). Make sure that your calculator is in radian mode. Then input this:

1/sin(22pi/3) = -1.15

If you actually meant sec 22pi/3, then that is equivalent to 1/cos(22pi/3):

1/cos(22pi/3) = -2

Either of those two is the answer :)

Find the midpoint of the segment below
aniked [119]
1.
If we are given 2 points A(a, b) and B(c, d), 

the midpoint M, of segment AB has coordinates:

M_A_B=( \frac{a+c}{2} ,  \frac{b+d}{2} )

2.
We are given the points A(2, 3) and B(10, 3)

the midpoint of AB, is given by the above formula:

M_A_B=( \frac{2+10}{2} , \frac{3+3}{3} )=(6, 3)

3. 
Remark, since the segment is horizontal, that is the y-coordinate of both points is 3, the y coordinate of the midpoint will also be 3.

While the x coordinate is still found by \frac{2+10}{2}

Answer: (6, 3)

Meg inline skated for 7/10 mile. Write this distance as a decimal.
Kaylis [27]
Hi There!

The answer to 7/10 as a decimal is 0.7 mile, because you have to divide 7 by 10. Once you divide you should get 0.7mile.

So, 0.7 changed as a decimal is 0.7

Hope This Helps!
