rohan bought 3.4 pounds of cashews on wednesday 2.5 pounds on thursday and 4 pounds on friday. he is going to divide them equall

kenny6666 [7]

First, you would add all the pounds he bought altogether, to know how much he bought, and how many pounds he will divide amongst his friends. That's 3.4 + 2.5 + 4 which equals to 9.9.

So he divides 9.9 pounds of cashews between himself and his two friends, and that makes it dividing 9.9 pounds between two people. That would simply make it : 9.9 ÷ 3, which equals to 3.3

Each friend will get 3.3 pounds of cashews.

An irrigation system (sprinkler) has a parabolic pattern. The height, in feet, of the spray of water is given by the equation h(

Answer:

7.5 ft
32.5 ft, 5 ft
10.7 ft

Step-by-step explanation:

a) The starting height is h(0) = 7.5 feet, the constant in the quadratic function.

The irrigation system is positioned 7.5 feet above the ground

b) The axis of symmetry for quadratic ax^2 +bx +c is x = -b/(2a). For this quadratic, that is x=-10/(2(-1)) = 5. This is the horizontal distance to the point of maximum height. The maximum height is ...

h(5) = (-5 +10)(5) +7.5 = 32.5 . . . feet

The spray reaches a maximum height of 32.5 feet at a horizontal distance of 5 feet from the sprinkler head.

c) The maximum distance will be √32.5 + 5 ≈ 10.7 ft.

The spray reaches the ground at about 10.7 feet away.
