The carousel at a local theme park has a diameter of 32 feet. each ride last three minutes and the speed of the carousel is 4.3
Liula [17]

Answer:

1297.37 feet.

Step-by-step explanation:

Given:

The carousel at a local theme park has a diameter of 32 feet.

Each ride last three minutes and the speed of the carousel is 4.3 revolutions per minute.

<u>Question asked:</u>

What is the maximum distance riders travel in one full ride? Round to the nearest hundredth.

<u>Solution:</u>

First of all we will find the radius of the carousel:-

Diameter = 32 feet

Radius, r = \frac{Diameter}{2} =\frac{32}{2} =16\ feet

Now, we will find distance covered by the carousel in one ride that means its circumference;

Circumference\ of \ the \ circle=2\pi r

                                               =2\times\frac{22}{7} \times16\\ \\ =\frac{704}{7} \\ \\ =100.571\ feet

In 1 minute, number of revolution taken by carousel = 4.3

<u>As each ride last for 3 minutes:-</u>

In 3 minutes, number of revolution taken by carousel = 3 \times 4.3 = 12.9

In 1 revolution, distance covered by carousel = 100.571 feet

In 12.9 revolution, distance covered by carousel = 100.571  \times 12.9

                                                                                 = 1297.365 feet

Thus, the maximum distance riders travel in one full ride is 1297.37 feet.

Answer:

Step-by-step explanation:

Consider the quadratic equation, we have

ax^2+bx+c=0

Dividing the equation by a, we get

x^2+\frac{b}{a}x+\frac{c}{a}=0

Put \frac{c}{a} on the other side,

x^2+\frac{b}{a}x=\frac{-c}{a}

Add (\frac{b}{2a})^2 on both the sides,

x^2+\frac{b}{a}x+(\frac{b}{2a})^2=\frac{-c}{a}+(\frac{b}{2a})^2

completing the square, we have

(x+\frac{b}{2a})^2=\frac{-c}{a}+(\frac{b}{2a})^2

Now, solving for x,

x+\frac{b}{2a}={\pm}\sqrt{\frac{-c}{a}+(\frac{b}{2a})^2}

x=\frac{-b}{2a}{\pm}\sqrt{\frac{-c}{a}+(\frac{b}{2a})^2}

Multiply right side by \frac{2a}{2a},

x=\frac{-b{\pm}\sqrt{b^2-4ac}}{2a}

which is the required quadratic formula.

<h2>1.</h2><h3>1)</h3>

Put the given values of p and q in the factored form equation.

... f(x) = (x -(-1))(x -(-2)) . . . . p and q values put in

... f(x) = (x +1)(x +2) . . . . . . .simplified

<h3>2)</h3>

Multiplying the factors, we have

... f(x) = x(x +2) + 1(x +2) = x² +2x +1x +2

... f(x) = x² +3x +2

<h2>2.</h2>

We want to factor x³ -x² -6x. We notice first of all that x is a factor of all terms. Thus we have

... = x(x² -x -6)

Now, we're looking for factors of -6 that add up to -1. Those are -3 and 2. Thus the factorization is ...

... = x(x -3)(x +2)

<h2>3.</h2>

We want a description of the structure and an equivalent expression for

... 64x⁹ -216

We note that 64, 216, and x⁹ are all cubes, so this expression is ...

... the difference of cubes.

It can be rewritten to

... = 8((2x³)³ -3³)

and so can be factored as

... = 8(2x³ -3)(4x⁶ +6x³ +9)
