Answer:
π
Step-by-step explanation:
Solve for x on the interval [0, 2pi]
Given the equation
Sinx = cosx + 1
Square both sides of the equation
Sin²x = (cos x + 1)²
Sin²x = cos²x + 2cos x + 1
Since Sin²x = 1 - cos²x
1 - cos²x = cos²x + 2cos x + 1
Collect like terms
1-1-cos²x-cos²x-2cos x = 0
-2cos²x-2cos x = 0
-2cos²x = 2cos x
-cosx = 1
cos x = -1
x = arccos -1
x = 180 degrees
<em>Hence the value of x = π</em>
Answer:
The answer is A.
Step-by-step explanation:
To find the value you have to know how many hours the repairman took to repair. Then after you find how many hours he took multiply the hours by 35 than add 25.
So the equation would look like 35x hr+25 =
hr=hours
Answer:
A, F, and C are the correct options.
Step-by-step explanation:
[- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).
<h3>What are linear equations?</h3>
- A linear equation in one variable is a mathematical expression for an equation with only one variable.
- While any two real integers can represent A and B, the ambiguous variable x has just one possible value.
- The formula is Ax + B = 0.
- 9x + 78 = 18 is an example of a linear equation with just one variable.
So, we have:
- (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)
Now, calculate as follows:
- = (3r²s+ 4rs+2-16r²s²) - (7sr²+10-13r²s²)
- = 3r²s+ 4rs+2-16r²s² - 7sr²- 10 + 13r²s²
- = 13r²s² - 16r²s² - 7sr² + 3r²s + 4rs - 10 + 2
- = - 3r²s² - 4sr² + 4rs - 8
Therefore, [- 3r²s² - 4sr² + 4rs - 8] is the resultant answer when we subtract the linear equation (7sr²+10-13r²s²) from (3r²s+ 4rs+2-16r²s²).
