Answers are

Choice A) function is W(n) = 4n+4
Choice C) input values for the function are natural numbers
Choice G) figure 8 has 36 white tiles

There are only three correct answers

===========================================
Explanation:

Figure 1 has 1 red tile and 8 white tiles (9 total)
Figure 2 has 4 red tiles and 12 white tiles (16 total)
Figure 3 has 9 red tiles and 16 white tiles (25 total)
Figure 4 has 16 red tiles and 20 white tiles (36 total)

Things to notice
* The pattern counts for the red tiles are perfect squares (1, 4, 9, 16)

* The total number of tiles are also perfect squares (9, 16, 25, 36)

* The number of white tiles can be counted, but its much easier to use the formula W = T - R
W = number of white tiles
T = total number of tiles
R = number of red tiles

* The pattern for the white tile counts is 8,12,16,20 so we basically add on 4 each time. The formula is W(n) = 4n+4. Plug in n = 1 and it leads to W(n) = 8 as expected. Plug in n = 2 and it leads to W = 12 etc. 

The input n is the number of the figure which is a natural number. Natural numbers are {1, 2, 3, 4, ...} which are counting numbers. The function is NOT continuous. We can't plug in n = 1.5 for instance. The input does not represent the number of white tiles as that is the output.

If we plugged in n = 6, then we get
W(n) = 4n+4
W(6) = 4*6+4
W(6) = 30
so figure 6 will have 30 white tiles (not 10)

Do the same for n = 8
W(n) = 4n+4
W(8) = 4*8+4
W(8) = 36
figure 8 has 36 white tiles

What is the measure of x?
UkoKoshka [18]

Answer:

x=4

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+5) *x = 6^2

x^2 +5x = 36

Subtract 36 from each side

x^2 +5x - 36 = 0

Factor

( x-4) (x+9) = 0

Using the zero product property

x-4 = 0  x+9 =0

x = 4  x=-9

Cannot be negative since that is negative length

x=4

What is a rational number?
MAVERICK [17]

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.
