Find the common ratio for the following sequence .1, .01, .001
morpeh [17]

Answer:

0.1

Step-by-step explanation:

The <em>common ratio</em> of a sequence is the number you multiply one term to get the next one. Here, we multiply 0.1 by 0.1 to get 0.01, and 0.01 by 0.1 to get 0.001, so our common ratio is 0.1.

To the nearest degree, what i’d the measure of angle Z?<br> A. 30<br> B. 32<br> C. 47<br> D. 49
miskamm [114]

Answer:

C

Step-by-step explanation:

Using the cosine rule

cosZ = \frac{7^2+8^2-6^2}{2(7)(8)} = \frac{49+64-36}{112} = \frac{77}{112} , thus

Z = cos^{-1} (\frac{77}{112} ) ≈ 47° ( to the nearest degree ) → C
