Step-by-step explanation:
(D) One circle : four triangles
Example:
One triangle is 1/4 of a circle
(A) One circle : four triangles
Example:
If there is two circles, the triangles will double like it shows [evidences]
Answer:
71
Step-by-step explanation:
4, 7, 12, 21, 38, ...
- 2+2=2¹+2
- 4+3= 2²+3
- 8+4= 2³+4
- 16+5= 2⁴+5
- 32+6= 2⁵+6

nth term:
Please refer to my image where it shows my work as I’m explaining.
Okay, for system 1:
1. I am using the elimination method to solve. So I check if all the terms are lined up and if any are the same. I found that 2X are common in both equations.
2. The goal is to “eliminate” the term hence the name. So I can choose to add or subtract. I chose subtraction because 2 - 2 equals 0 which is our goal. Solve for the rest of the terms. This will lead to getting y =4. Refer to image for the work.
3. Last step to to find the X value. We do this by picking any of the given equations,then substitute y with 4 and solve to eventually get x = 10. Refer to image for the work.
FOR SYSTEM 2:
1. Again, I am using the elimination method to solve. I noticed that NONE of the terms are in common so I will have to intervene. You can chose any term to create a match with but I chose Y since it was the one I could use the smallest number to multiply with. When multiplying, DONT just multiply Y, multiply ALL the terms in the equation or else everything will crash.
2. Now that I have terms in common I can choose to add or subtract. I chose subtraction because 2-2 equals zero which is what we want. Solve look at image for my process which lead to X = -8
3. Last step is to find the value of Y. Chose any of the given equations in system 2 then substitute x with -8. Refer to image to see process. It lead to y = 20
To check the validity of the answers, substitute the x and y values into both equations both side of the equal side should have the same number. Hope that helped!
Answer:
C. It will increase by about 0.6%
Step-by-step explanation:
Since, the effective interest rate is,

Where, i is the stated interest rate,
n is the number of compounding periods,
Here, i = 11.28 % = 0.1128,
n = 365 ( 1 year = 365 days ),
Hence, the effective interest rate would be,

=0.119388521952
Now, the changes in effective interest rate = Effective interest rate - Stated interest rate
= 0.119388521952 - 0.1128
= 0.006588521952 ≈ 0.006 = 0.6 %
Hence, It will increased by about 0.6 %,
Option A is correct.
Hope this helps :)
