³√81 × 3^⅔

= 81^⅓ × 3^⅔

= 3^⁴(⅓) × 3^⅔

= 3^1⅓ × 3^⅔

= 3²

= 9 inches²

Since Molly can make 4 pancakes in 6 minutes if you divide 60 by 6 you get 10 so Molly can make 10 pancakes every hour

**Answer:**

(a) 7.5 seconds

(b) The horizontal distance the package travel during its descent is 1737.8 ft

**Step-by-step explanation:**

(a) The given function for the height of the object is s = -16·t² + v₀·t + s₀

The initial height of the object s₀ = 900 feet

The initial vertical velocity of the object v₀ = 0 m/s

The time it takes the package to strike the ground is found as follows;

0 = -16·t² + 0×t + 900

900 = 16·t²

t² = 900/16 = 62.25

t = √62.25 = 7.5 seconds

(b) Given that the horizontal velocity of the package is given as 158 miles/hour, we have

158 miles/hour = 231.7126 ft/s

The horizontal distance the package covers in the 7.5 second of vertical flight = 231.7126 ft/s × 7.5 s = 1737.8445 feet = 1737.8 ft to one decimal place

The horizontal distance the package travel during its descent = 1737.8 ft.
