Answer:
C. cot theta
Step-by-step explanation:
(csc theta -cot theta )/(sec theta -1)
csc = 1/ sin
cot = cos / sin
sec = 1 / cos
Let x = theta
(1/ sin x -cos x / sin x )/(1/ cos x -1)
Getting a common denominator in the denominator and combining terms
(1- cos x)/ sinx / ( 1 - cos x) / cos x
(1- cosx) (1- cosx)
----------- ÷ ------------
sinx cos x
Copy dot flip
(1- cosx) cosx
----------- * ------------
sinx 1 -cos x
Cancel like terms
cos x / sin x
cos / sin = cot
cot x
cot theta
The coordinate of the solution is (2,2)
Answer:
3) x= 3, -2
4) 36
Step-by-step explanation:
3) x= 3, -2
4) 36
A.the measures of the angles must be equal
Vertical Angles- are the angles opposite of each other when two lines cross. They are always equal.
Multiply 2207 by .27 and get $595.89. This is the first year depreciation.
After 1 year the computer has a value of $1611.11.
Year 2 depreciation would be 1611.11 X .27= $434
1611.11-434= $1,177.11
Year 3 1177.11 X .27= $317.82
1177.11- 317.82= $859.29
Final year 859.29 X .27= 232
$859.29- 232= $627.29
