<h2>Answer:</h2>

The dollars worth of zinc which is contained in hair cut in the United States every year is:

                         $ 2,220,000

<h2>Step-by-step explanation:</h2>

The total kilograms of hair that are  cut in the United States are: 25,000,000 kg

Also, the amount of zinc present in 1kg of hair is: 0.0002 kg

Hence, the amount of zinc present in 25,000,000 kg of hair is:

25,000,000×0.0002=5,000 kg

Also, cost of 1 kg of zinc= $ 444

Hence, cost of 5,000 kg of zinc will be: 5,000×444

Hence, cost of 5,000 kg of zinc=$  2,220,000

A ladder is leaning against a vertical wall. The distance from the top of the ladder to the base of the wall is 17 feet. The dis
Gennadij [26K]

Answer:

18.4 feet

Step-by-step explanation:

-use the formula C^2 = A^2 + B^2 for a right triangle, which is made by the ladder and the wall.

-let the ladder be C, the wall be a, the base to the bottom be b.

-substitude into the equation, which will leave us with:

C^2 = 17^2 + 7^2

C^2 = 289 + 49

C^2 = 338

C = square root of 338, which is 18.4 feet!

Answer:

Vertex → (2, 4)

Step-by-step explanation:

Quadratic equation has been given as,

y = -x² + 4x

We rewrite this equation in the form of a function as,

f(x) = - x² + 4x

By comparing this equation with the standard quadratic equation,

y = ax² + bx + c

a = -1 and b = 4

Vertex of the parabola represented by this equation is given by [-\frac{b}{2a}, f(\frac{-b}{2a})]

x coordinate = -\frac{4}{2(-1)}

                     = 2

y-coordinate = f(2)

                     = - (2)² + 4(2)

                     = -4 + 8

                     = 4

Therefore, vertex of the given function is (2, 4)
