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:
3 gallons
Step-by-step explanation:
if 1 gallon is consumed for 54 miles
what about 164 miles ..
so you take 1 * 162
..........
54
Answer:
You cannot put this in an input output chart because one value of x has 2 y values.
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
axis of symmetry always pass through X coordinate of vertex.
here vertex is (h,k)= (3,5)
so x coordinate is 3.
so the equation of the axis of the symmetry is X=3
Answer:
x = 3/61
Step-by-step explanation:
Hi there!
49(9x+1) = 14(x+5)
Divide both sides by 7
7(9x+1) = 2(x+5)
Open up the parentheses
63x+7 = 2x+10
Combine like terms
63x-2x = 10-7
61x = 3
Divide both sides by 61
x = 3/61
I hope this helps!
