I belive the answer to be b
Answer:
See explanation
Step-by-step explanation:
The given trigonometric equation is 
.
We take the inverse cosine of both sides to get:
to the nearest degree
None of the options satisfies the given equation.
But if the question is actually;
Then;

.
Or
.
In this case the answer will be B

Answer:
C. (9, 18)
Step-by-step explanation:
Given R(3, 5), a dilation by a factor of 3 will multiply each coordinate to give ...
(9, 15)
Then the translation up by 3 will give you the image coordinates ...
(x, y) ⇒ (x, y+3)
(9, 15) ⇒ (9, 15 +3) = (9, 18)
The coordinates of R' are (9, 18), matching choice C.

<em>Comment on multiple choice answers</em>
As it often does, here it works to "guess" the answer that has the coordinates that are most-repeated. An x-coordinate of 9 is part of 3 answer choices; a y-coordinate of 18 is the only repeated value in the answer choices. If you were to guess, an appropriate guess would be (9, 18). That happens to be correct in this case.
The correct answer should 1.1333
The inner diameter of the washer is 7/10 inch, this value is gotten by multiplying the path by 2 and subtracting the result from the outer diameter
<h3>Mensuration of Shapes</h3>
Given Data
- Path Distance = 3/20 inch
The inner diameter
= Outer Diameter - 2*Path Distance
= 1 - 2*3/20
= 1- 6/20
= 1- 3/10
= 1/1 - 3/10
Find the LCM we have 10
= 10-3/10
= 7/10 inch
