<h2>Answer:</h2>

<h2>Explanation:</h2>
Given the equation expressed as:

First, we need to calculate the value of "x" from the given expression.
Step 1: Given the equation 2x + 5 = 8x
Step 2: Subtract 5 from both sides:

Step 3: Subtract 8x from both sides

Step 4: Divide both sides by -6

Step 5: Get the value of 12x. Substitute x = 5/6 into the expression to have:

Therefore the value of 12x is 10
Answer:
NO amount of hour passed between two consecutive times when the water in the tank is at its maximum height
Step-by-step explanation:
Given the water tank level modelled by the function h(t)=8cos(pi t /7)+11.5. At maximum height, the velocity of the water tank is zero
Velocity is the change in distance with respect to time.
V = {d(h(t)}/dt = -8π/7sin(πt/7)
At maximum height, -8π/7sin(πt/7) = 0
-Sin(πt/7) = 0
sin(πt/7) = 0
Taking the arcsin of both sides
arcsin(sin(πt/7)) = arcsin0
πt/7 = 0
t = 0
This shows that NO hour passed between two consecutive times when the water in the tank is at its maximum height
Answer:
csc π.
Step-by-step explanation:
csc π because csc = hypotenuse / opposite side and the opposite side = 0. Anything divided by zero is undefined.
Another way to the same conclusion is: we know that sin π = 0 and csc π = 1 / sin π = 1 / 0 which is indeterminate.
