1 answer:
Answer:
I think the second option is the most appropriate option.
Step-by-step explanation:
Mikhail believes he can use the multiplication expression to find the total number of pound servings of rice he can make from 6 pounds of rice.
Now, we have to select the statement from the four options that best explains why Mikhail is correct or incorrect.
I think the second option is the most appropriate option.
So, Mikhail is correct in using a multiplication expression because 1/2 is the number of servings per pound. (Answer)

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.
