How can the lengths of corresponding sides within similar triangles be helpful in finding unknown side lengths?

klemol [59]

Because you only have to find the length of one side to find the length of the rest of the sides.

Grade 6 students sold 318 tickets for a school pay. The number of adult tickets was six

9966 [12]

Total: 318
Student tickets: x
Adult tickets: 3x+6

x+(3x+6)=318 -> 4x+6=318 -> 4x=312 -> x=78

3(78)+6 = 234+6 = 240

240 adult tickets were sold

A function can be represented by equations and tables

4 users are logged in by 9am
The domain is [3,23] and the range of the function is [3,4]

<h3>The number of users at 9am</h3>

The function is given as:

$g(x) = \frac14 \sqrt{x - 3} + 3$

At 9am, x = 9.

So, we have:

$g(x) = \frac14 \sqrt{9 - 3} + 3$

$g(x) = \frac14 \sqrt{6} + 3$

Simplify

$g(9) = 3.6$

Approximate

$g(9) = 4$

Hence, 4 users are logged in by 9am

<h3>The domain</h3>

Set the radical to 0

$x - 3 = 0$

Solve for x

$x = 3$

The maximum time after midnight is 23 hours.

So, the domain is [3,23]

<h3>The range</h3>

When x = 3, we have:

$g(x) = \frac14 \sqrt{x - 3} + 3$

$g(3) = \frac 14 * \sqrt{3 - 3} + 3 = 3$

When x = 23, we have:

$g(23) = \frac 14 * \sqrt{23 - 3} + 3 = 4$

So, the range of the function is [3,4]
