Which answer describes the type of sequence? 200, 40, 8, 1.6, ...
GalinKa [24]

Answer:

Option 1  the given sequence is a geometric.

Step-by-step explanation:

We have been given with the series

200,40,8,1.6

Arithmetic sequence is the sequence in which difference between consecutive terms is same that is common difference d

d=a_2-a_1

d=40-200=-160   herea_2=40,a_1=200

d=8-40=-32          herea_2=8,a_1=40

We can see the difference is not same

Hence, the given sequence is not arithmetic sequence.


Geometric sequence is the sequence in which ratio of consecutive terms is same that is common ratio r

r=\frac{a_2}{a_1}

r=\frac{40}{200}=\frac{1}{5}   herea_2=40,a_1=200

r=\frac{8}{40}=\frac{1}{5}          herea_2=8,a_1=40

r=\frac{1.6}{8}=\frac{1}{5}             herea_2=1.6,a_1=8

We can see the ratio is  same.

Hence, given sequence is geometric

Therefore, Option 1 is correct given sequence is geometric.

Help me i don’t know how to do this
barxatty [35]

Hi!

y = 16

x = 32

<h3 /><h3>In 30-60-90 triangles, the hypotenuse is double the length of the shortest leg, and the longer leg is \sqrt{3} times the shorter leg.</h3>

We are given the longest leg. To find the shortest leg, we must divide the longest leg value by \sqrt{3}

\cfrac{16\sqrt{3} }{\sqrt{3} }

The radicals cancel out and we are left with 16.

The length of y (the shortest leg) is 16.

Now, we also know that the hypotenuse is double the shortest leg. The shortest leg is 16, so if we double that, it's 32.
