A child stands at the foot of a tall slide and throws a ball toward the top of the slide. The foot of
the slide is located at the origin; the shape of the slide is modeled by the equation y = 2x; the
path of the ball through the air is modeled by y *? + 5x, where x is the horizontal distance
traveled by the ball and y is the height of the ball (both distances in feet). When the ball hits the
slide, how many feet off the ground will it be?

Rowdy will be sent to coca so ​

Answers

Answer:

3,000.

Step-by-step explanation:

In order to know the number that equals 300th tenths, the given number has to be multiplied by ten. Therefore, the following calculation has to be done:

300 x 10 = X

3,000 = X

As can be seen, the multiplication of 300 by 10 gives as a result the number three thousand. Therefore, the number that equals 300th tenths is 3,000.

Answers

Answer:

there is no success or failure in the scenario

Step-by-step explanation:

khan academy

The average number of hours worked. Is not a binomial variable.

Binomial variable.

A binomial variable is a variable that can take either of two forms. It could either be heads or tail, yes or no and success or failure. For example, if a coin is tossed, it can either be heads or tail. Thus, it is a binomial variable.

The average hours worked can have more than two values. Thus it is not a binomial variable.

lesser x =

greater x =

Answers

Answer:

lesser x = -2

greater x = 2

Step-by-step explanation:

The values of a function f(x) are the values of x for which f(x) = 0.

In this question:

[tex]f(x) = 5x^2 - 20[/tex]

So, finding the zeros:

[tex]5x^2 - 20 = 0[/tex]

[tex]5x^2 = 20[/tex]

[tex]x^2 = \frac{20}{5}[/tex]

[tex]x^2 = 4[/tex]

[tex]x = \pm \sqrt{4}[/tex]

[tex]x = \pm 2[/tex]

So

lesser x = -2

greater x = 2
