Answer:

7pi or ≈21.98 cm²

Step-by-step explanation:

The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi

the area of the 2 smaller circles is pi1^2*2 so 2pi

9pi-2pi=

7pi cm² =

7pi≈21.98 cm² (with pi as 3.14)

If you could explain how I would get this answer also that'd be great

For now, we can’t get a definite answer. We can model with an equation, but we cannot find the absolute amount Jocelyn will earn, as her hourly rates are both variables. All we must do to create an equation for this is multiply the amount of hours by the rate and add. You could model like this:
25n + 15x = total amount earned

Indicate a general rule for the <img src="https://tex.z-dn.net/?f=%20n%5E%7Bth%7D" id="TexFormula1" title=" n^{th}" alt=" n^{th}

Answer: option D) An = 3an - 9a

Justification:

1) That is an arithmetic sequence which you prove by determining the difference between two consecutive terms (which shall be constant if it indeed is an arithmetic sequence):

2)

Second term - first term = -3a - (-6a) = -3a + 6a = 3a
Third term - second term = 0a - (-3a) = 3a
Fourth term - third term = 3a - 0a = 3a
Fith term - fourth term = 6a - 3a = 3a

Therefore, it is an arithmetic sequence with difference d = 3a.

3) the general rule for the nth term of an arithmetic sequence is given by the formula:

An = Ao + d (n - 1)

Where Ao = -6a and d, as determined above, is 3a

=> An = -6a + 3a (n - 1)

Expand the parenthesis (distributive property) =>

An = -6a + 3an - 3a = -9a + 3an = 3an - 9a = option D. <------- answer.
