Answer:
8. Arithmetic Progression
9. 
Step-by-step explanation:
Given
Solving (8): Arithmetic or Geometric
We start by checking if it is arithmetic by checking for common difference (d).
This gives:
<em>Because the common difference is equal, then it is an arithmetic progression</em>
<em></em>
Solving (8):
To find f(9), we substitute 9 for n
We need to solve for f(8); substitute 8 for n
We need to solve for f(7); substitute 7 for n
We need to solve for f(6); substitute 6 for n
We need to solve for f(5); substitute 6 for n
From the function, f(4) = 25 and f(1) = 55.
So:

Answer:
the answer is 17.60
Step-by-step explanation:
if im not mistaken the answer is 17.60. this is because 1/3 of 24 is 8, and 12x2 (the two kids) equals 24, and 60% off of 24 is 9.6. 8+9.6 is 17.6(0) :)
Answer:
Step-by-step explanation:
Start by determining the simpler angle 
(or, the complement of the highlighted angle in red on your image). The cosine of that angle is
Now, back to the actual red-circled angle. That one is going in the negative direction and ends up in the same position on the unit circle. Since cosine is an even function, its value is the same whether you evaluate at an angle theta, or its complement 2pi-theta. So, the final answer is:
Estimation would be 90 x 70
Which is 6300.
Real answer of 92 x 68
= 6256
