Simplify.<br> (WILL GIVE BRAINLIEST)

Novosadov [1.4K]

Answer:

$\frac{\sqrt{x} }{2x}$

Step-by-step explanation:

Rationalize the denominator first (keep in mind we are NOT solving this because there is no equals sign here. We are merely simplifying.)

$\frac{\sqrt{5x} }{x\sqrt{20} } *\frac{\sqrt{20} }{\sqrt{20} } =\frac{\sqrt{100x} }{20x}$

Now simplify by taking the square root of 100 to get:

$\frac{10\sqrt{x} }{20x}$

Divide numerator and denomiator by 10 to get:

$\frac{\sqrt{x} }{2x}$

Suppose that the distance of fly balls hit to the outfield (in baseball) is normally distributed with a mean of 250 feet and a s

Korvikt [17]

Answer:

On the graphing calculator, use the function normCdf, where

lower bound = -9999
upper bound = 210
mean = 250
standard deviation = 46

It will result in normCdf(-9999,210,250,46) ≈ 0.192269 or 19.2269%

The height of a soccer ball thrown of a hill can be modeled by the equation h = -16t^2 -8t +120.

inessss [21]

Answer:

120 feet

Step-by-step explanation:

You have to find the y-intercept to calculate the initial hight, this can be done by substituting o in for t

h(0)= -16(0)^2-8(0)+120

=120ft
