Answer:

Option C. exponential

Step-by-step explanation:

"Common Ratio" is the term always used in geometric sequence which is in the exponential form.

We can write the function defined by exponential as

$f(x)=r^{n}$

Where r is the common ratio and n is denoting number of terms.

Now if we plug in the values of n as 1, 2, 3, 4

The sequence will be $r^{1}, r^{2}, r^{3}, r^{4}$ and so on.

Therefore the exponential function can be used to model data pairs that have a common ratio.

Correct answer is C.

For example 2, 4, 8, 16, 32...

$2=\frac{4}{2} = \frac{8}{4} = \frac{16}{8} = \frac{32}{16} =...$

$y=2^x$

For circle O, mCD=125° and m

Burka [1]

CA is a diameter of the circle, so $m\widehat{AC}=180^\circ$ , which means $m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ$ . Then $m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ$ .

This means $m\angle CBO=55^\circ-35^\circ=20^\circ$ . Also, if $m\angle AOB=55^\circ$ , then $m\angle BOC=180^\circ-55^\circ=125^\circ$ , which in turns tells us that $m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ$ .
