An irrigation system (sprinkler) has a parabolic pattern. The height, in feet, of the spray of water is given by the equation h(
jasenka [17]

9514 1404 393

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 <u> 7.5 </u> 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 <u> 32.5 </u> feet at a horizontal distance of <u> 5 </u> feet from the sprinkler head.

__

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

The spray reaches the ground at about <u> 10.7 </u> feet away.

the ages of two friends Sunaina and Tanish are differ by 2 years sunaina's father is twice as old as Sunaina and Tanisha is twic
nikklg [1K]

Let S represent Sunaina's age.

Let T represent Tanish's age.

So 2S - T/2 = 40, 4S - T = 80.

Either S - T = 2 or T - S = 2. Let's try both cases.

Either 3S = 78 or 3S = 82.

Since 82 is not a multiple of 3, S = 26.

So Sunaina is 26 years old and Tanish is 24 years old.

The probability density function f(x) of a random variable X that has a uniform distribution between a and b is:
Lunna [17]

The probability density function (pdf) is;

f(x)=\frac{1}{b - a} for a ≤ x ≤ b.

while the mean is given as \frac{a + b}{2}

And the standard deviation given as \sqrt{\frac{(b - a)^{2} }{12} }
