A(1, 1), B(7, 1), C(1, 9)

AB = 7 - 1 = 6

AC = 9 - 1 = 8

Use the Pythagorean theorem:

AB² + AC² = BC²

Substitute:

BC² = 6² + 8²

BC² = 36 + 64

BC² = 100 → BC = √100 → BC = 10

The perimeter of ΔABC:

P = 6 + 8 + 10 = 24

<h3>Answer: 24 units</h3>

Given the relation (2,3), (4,7), (6,11), (x,3), which of the following values of x will make the relation function

Elan Coil [88]

As you said, (x,3) = (2,3)
So x = 2

Thank you very much.

Added to Six Flags St. Louis in the Colossus is a giant Ferris wheel. Its diameter is 165 feet, it rotates at a rate of about 1.

Answer:

The height of the rider as a function of time is $h(t) = 15 + 82.5\cdot (1-\cos 0.168t) \,[ft]$ , where time is measured in seconds.

Step-by-step explanation:

Given that Ferris wheel rotates at constant rate and rider begins at the bottom of the wheel, the height of the rider as a function of time is modelled after this expression:

$h(t) = h_{bottom} + (1-\cos \omega t)\cdot r_{w}$

Where:

$h_{bottom}$ - Height of the bottom with respect to ground, measured in feet.

$\omega$ - Angular speed of the ferris wheel, measured in radians per second.

$t$ - Time, measured in seconds.

$r_{w}$ - Radius of the Ferris wheel, measured in feet.

The angular speed of the ferris wheel, measured in radians per second, is obtained from the following expression:

$\omega = \frac{\pi}{30}\cdot \dot n$

Where:

$\dot n$ - Angular speed of the ferris wheel, measured in revolutions per minute.

If $\dot n = 1.6\,rpm$ , then:

$\omega = \frac{\pi}{30}\cdot (1.6\,rpm)$

$\omega \approx 0.168\,\frac{rad}{s}$

Now, given that $h_{bottom} = 15\,ft$ , $r_{w} = 82.5\,ft$ and $\omega \approx 0.168\,\frac{rad}{s}$ , the height of the rider as a function of time is:

$h(t) = 15 + 82.5\cdot (1-\cos 0.168t) \,[ft]$

I'm having trouble understanding this

Readme [11.4K]

Since angles 6 and 2 are corresponding angles, that means that if they are congruent, we can say, through a converse theorem, that the lines which they lie on are parallel. Since, indeed, angles 6 and 2 are equal, then we can definitely see how the lines x and y are parallel.
