There are no graphs attached, so I punched the equation into a calculator and this is what it gave me!! I hope this helps
The answer would be number 1. 173 units^2
Answer :x+3x-4= total # of coins
4x-4= total # of coins
Step-by-step explanation:
The answer is True because it has real numbers in it
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>
