Answer:
Second option:

Step-by-step explanation:
We can observe that the radius of the circle is given. This is:

And the missing measures are the diameter of the circle and the circumference.
Since the diameter of a circle is twice the radius, we get that this is:

To find the circumference of the circle, we can use this formula:

Where "r" is the radius of the circle.
Substituting the radius into the formula, we get:

Could you please take the picture at a better angle
Answer:
23 degrees
Step-by-Step Explanation:
SU is the transversal between the two parallel lines ST and RU
so angle SUR is equal to angle TSV=31 degrees
angle RVU is 126 degrees also because it is a vertical angle with angle SVT
angle URV is the angle being looked for in the triangle URV, and we know the two others sum to 157 degrees.
Therefore, it is 23 degrees.
Answer:
The total number of the payments is 18 ⇒ answer A
Step-by-step explanation:
* Lets revise the rule of compounded monthly payment
→
, where
- A is the loan amount
- r is monthly interest in decimal (R/12*100))
- n the total number of payments
∵ A = $1100
∵ EMI = $71.5
- Interest rate is 19.2% APR
∵ r = 
- Substitute these values in the rule to find n
∴ 71.5 = ![\frac{1100(0.016)}{[1-\frac{1}{(1+0.016)^{n}}]}=\frac{17.6}{[1-\frac{1}{(1.016)^{n}}]}](https://tex.z-dn.net/?f=%5Cfrac%7B1100%280.016%29%7D%7B%5B1-%5Cfrac%7B1%7D%7B%281%2B0.016%29%5E%7Bn%7D%7D%5D%7D%3D%5Cfrac%7B17.6%7D%7B%5B1-%5Cfrac%7B1%7D%7B%281.016%29%5E%7Bn%7D%7D%5D%7D)
- By using cross multiplication
∴ 71.5[1 -
] = 17.6
- Divide both sides by 71.5
∴ 1 -
= 
- Subtract 1 from both sides
∴ -
= - 
- Multiply both sides by -1
∴
= 
- By using cross multiplication
∴ 49[
] = 65
- Divide both sides by 49
∴
= 
- Insert log for both sides
∴ ㏒
= log(
)
- Put n in-front of the ㏒
∴ n㏒(1.016) = ㏒(
)
- Divide both sides by ㏒(1.016)
∴ n = 17.8 ≅ 18
* <em>The total number of the payments is 18</em>
