the water in a fish tank is decreasing at a rate of 2 inches per hour
Rate of change is the derivative
Rate of change in height with respect to time is 2 inches per hour
so
(a)
unit is feet^2 so its area
the unit of area is always units^2
so da/dt is the rate of change in area with respect to time
(b)
r is the radius
so dr/dt is the rate of change in radius with respect to time
Radius is decreasing at the rate of 40 cm per minute
(c)
v is the volume . the unit of volume is always cubic units
so dv/dt is the rate of change in volume with respect to time
Volume is decreasing at the rate of 10 meter cube per second
Answer:
-52
Step-by-step explanation:
Think of it this way. Opposite means to take the negation. So we are taking the negation of the negation of negative 52. This means mathematically:
- ( - ( -52 ) ) == -52

Which statement about solving inequalities is true?
Solving Inequalities Involving Multiplication
Let's start with the true statement:10 > 5
Next, multiply both sides by the same positive number:
10 • 2 > 5 • 2
20 is greater than 10, so you still have a true inequality:
20 > 10
When you multiply by a positive number, leave the inequality sign as it is!
