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)
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
Ok? Is there like an equation or something that I can see so then I can help you?
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.
