Answer:

Geometric Sequence

Step-by-step explanation:

In this case it is Geometric Sequence as it has a common ratio of 5

Formula for nth term: a(n) = ar∧n-1

so if we take the third term we will calculate as follows:

50 = 2(r)∧3-1

50÷2 = r∧2

√25= r

r=5

Can't tell you if that is definitely correct, but I tried. All I did was try to figure out the common ratio for each sequence.

E.g. 3x36 = 108.

Find the angle of depression
stich3 [128]

Answer:

Step-by-step explanation:

From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.

A square with side lengths of 4 units is translated on the coordinate plane. One vertex of the image is at (2, 1). Which ordered
nirvana33 [79]
It says that's 4 units distant from the another vertex. So, if a square is formed by 4 equal sides and 4 right angles, then you just have to add 4 units on x or y.

-> (2, 1) -> + 4 units on X
-> = (6, 1)
or
-> (2, 1) -> +4 units on Y
-> = (2, 5)

(2, 5) isn't an answer so the unique possible answer is (6, 1)


Answer: (6, 1)
