Does this graph represent a function? Why or why not?

Mathematics

Answer:

A

Step-by-step explanation:

In order for a graph to be a function, it has to only cross the vertical (up and down) lines that it covers once. Since this is an angle, it crosses all the lines in two different places, and isn't a function.

What is the smallest 6 digit palindrome that is divisible by 99
Scorpion4ik [409]

Answer:

  • 108801

Step-by-step explanation:

<u>6-digit palindrome is the number n the form of:</u>

  • xyzzyx

<u>This is divisible by 11 by default as the sum of the digits in odd placed is same as sum of the number in even places (remember the divisibility rule by 11):</u>

  • x + z + y = y + z + x

Now, in order to be divisible by 99, the number must be divisible by 11 and 9.

According to divisibility rule by 9 the sum of all digits must be divisible by 9. <u>You can see In our case we need to have (the minimum):</u>

  • x + y + z = 9

<u>The smallest number we could get is when x is minimum, y is minimum, so:</u>

  • x = 1, y = 0, then y = 8

<u>The number we get is:</u>

  • 108801

<u>Proof:</u>

  • 108801/99 = 1099

The area of the scale drawing would be 1080 square centimeters or (1080 cm^2). I got this answer through first finding the area of the classroom in feet (which is A= lw = [18][20] = 360 ft^2) and then I proceeded to converting it to centimeters via given scale factor (3 cm = 1 foot) and had the answer of 1080 centimeters squared.
