pshichka [43]

Answer:

The each coffee shops receives 4 cases of juice everyday.

Step-by-step explanation:

The juice company produced 8064 cartons of juice in 21 days each day they produced the same number of cartons.

Therefore, each day the company produces \frac{8064}{21} = 384 cartons.

The juice company delivers those cartons in 16 areas of coffee shops.

So, each coffee shop receives \frac{384}{16} = 24 cartons of juice.

Now, the cartons were delivered in cases of six cartons per case and each coffee shop received an equal number of cases in each delivery.

Hence, each coffee shops receives \frac{24}{6} = 4 cases of juice everyday. (Answer)

Water is leaking out of an inverted conical tank at a rate of 6,500 cm3/min at the same time that water is being pumped into the
Nana76 [90]

Answer:

  285,753 cm³/min

Step-by-step explanation:

The rate of change of volume is the product of the water's surface area and its rate of change of depth.

At a depth of 2 m, the water has filled 1/3 of the 6 m depth of the tank. So, the radius at the water's surface will be 1/3 of the tank's radius of 2 m. The water's surface area is ...

  A = πr² = π(2/3 m)² = 4π/9 m²

The rate of change of depth is 0.2 m/min, so the volume of water is increasing at the rate ...

  dV/dt = (0.20 m/min)(4π/9 m²) = 8π/90 m³/min ≈ 279253 cm³/min

This change in volume is the difference between the rate at which water is being pumped in and the rate at which it is leaking out:

  2.8×10⁵ cm³/min = (input rate) - 6500 cm³/min

Adding 6500 cm³/min to the equation, we get ...

  input rate ≈ 285,753 cm³/min

pshichka [43]

Answer:

5x + 2

Step-by-step explanation:

Since logarithm has the following property:

If f(x)=b^x and g(x)=\log_bx,

Then fog=b^{\log_bx}=x and gof=\log_bbx=x

Therefore,

e^{\ln(5x + 2)}=e^{\log_e(5x+2)}=5x+2
