URGENT 20 POINTS <br> Select each graph that shows a function and its inverse.
Andre45 [30]

Answer: Graph first and fourth.

Step-by-step explanation:

If a function is reflected through line y=x,, we obtained an inverse function of that function.

In first graph,

The function is reflected through line y = x,

Hence, in this graph we obtained inverse functions.

In second graph,

The function is shifted horizontally,

This is why we did not get an inverse function.

In third graph,

The function is reflected through x-axis,

This is why we did not get the inverse of the function.

In fourth graph,

The function is reflected through line y = x,

Hence, in this graph we obtained inverse functions.

Find the 11th term of the geometric sequence 1, 4, 16, ...
drek231 [11]

Answer:

a(11) = 4^10 = 1048576

Step-by-step explanation:

The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4.  Each new term is 4 times the previous term.  Thus,

a(n) = 1*4^(n - 1), and

a(11) = 4^10 = 1048576

The population of the town increased from 175000 to 262500 in a decade. What is the average percent increase of population per y
Alenkinab [10]

Answer:

5%

Step-by-step explanation:

As given,

The population of the town increased from 175000 to 262500 in a decade.

⇒ In 10 years , population increased from 175000 to 262500

⇒% increase = \frac{262500 - 175000}{175000}× 100% = \frac{87500}{175000}×100% = 0.5×100% = 50%

Now,

Average % increase = \frac{percent increase}{Total years} = \frac{50}{10}% = 5%

∴ we get

Average percent increase of population per year = 5%

A soccer team wins 65% of its matches, and 15% of its matches end in a draw. If the team is scheduled to play 20 matches, about
STatiana [176]

Answer:  There are 4 matches that are expected to lose by a soccer team.

Step-by-step explanation:

Since we have given that

Probability that a soccer team wins = 65%

Probability that a soccer team ends in a draw = 15%

Total probability we get

65\%+15\%=80\%

Probability that matches are expected to lose is given by

100\%-80\%=20\%

Since number of matches is scheduled to play = 20

Number of matches expected to lose is given by

\frac{20}{100}\times 20\\\\=\frac{400}{100}\\\\=4

Hence, there are 4 matches that are expected to lose by a soccer team.
