The value of x in expression cos(2x-1) = sin(3x+6) is 17.
cos(2x-1) = sin(3x+6)
let
a = 2x - 1
b = 3x + 6
Therefore,
cos a = sin b
Therefore, a and b are complimentary.
Complimentary angles are angles that sum up to 90 degrees. Therefore,
2x - 1 + 3x + 6 = 90
2x + 3x - 1 + 6 = 90
5x + 5 = 90
5x = 90 - 5
5x = 85
x = 85 / 5
x = 17

B: 1/2
C: 81/100
D: 5/6
answer:
To determine which fraction is between 34 and 45, we can compare each fraction to these two numbers. Let's go through the options:
A: 77/100
This fraction is greater than both 34 and 45, so it is not between them.
B: 1/2
This fraction is smaller than both 34 and 45, so it is not between them.
C: 81/100
This fraction is greater than both 34 and 45, so it is not between them.
D: 5/6
This fraction is greater than 34 and smaller than 45, which means it is between them.
Therefore, the fraction that is between 34 and 45 is D: 5/6.
The inner and outer Radii of a cylindrical pipe are 5 cm and 4 cm respectively. find the area of cross section of the pipe.
Answer:
28.3 cm²
Step-by-step explanation:
You find the area of the whole section which is 5²π = 25π.
Then you find the area of the empty part which is 4²π = 16π.
Then you subtract to get 9π which is 28.27433388......
= 28.3 cm²
