Step-by-step explanation:
cot(x) cos(x) + cot(x) = 0
cot(x) (cos(x) + 1) = 0
cot(x) = 0 or cos(x) = -1
cot(x) = 0
x = π/2, 3π/2
x ≠ 0, π
cos(x) = -1
x = π
Therefore, the answer is x = π/2, 3π/2.
The answer is 50
X represents a toaster, x-20 represents a rice cooker
Use the equation 5x+3(x-20)=500
Solve for x and get 70.
A toaster is 70 but a rice cooker is 50
Solve for v:
Y = (a v^2)/2
Y = (a v^2)/2 is equivalent to (a v^2)/2 = Y:
(a v^2)/2 = Y
Divide both sides by a/2:
v^2 = (2 Y)/a
Take the square root of both sides:
Answer: v = sqrt(2) sqrt(Y/a) or v = -sqrt(2) sqrt(Y/a)
