For this one, to remove the 9 from the left you must multiply it on both sides; the answer is C. (The answer always has the opposite operation than the one used in the problem. The opposite of multiplication is division and the opposite of addition is subtraction.)

Type the correct answer in each box. If necessary, use / for the fraction bar. Complete the statements about series A and B. Ser

Answer:

Series A has an r value of 2/5 and series A has an r value of 3. The sum of the series A is 50/3

Step-by-step explanation:

A geometric sequence is in the form a, ar, ar², ar³, . . .

Where a is the first term and r is the common ratio = $\frac{a_{n+1}}{a_n}$

For series A: 10+4+8/5+16/25+32/125+⋯ The common ratio r is given as:

$r=\frac{a_{n+1}}{a_n}=\frac{4}{10} =\frac{2}{5}$

For series B: 1/5+3/5+9/5+27/5+81/5+⋯ The common ratio r is given as:

$r=\frac{a_{n+1}}{a_n}=\frac{3/5}{1/5} =3$

For series A a = 10, r = 2/5, which mean 0 < r < 1, the sum of the series is given as:

$S_{\infty}=\frac{a}{1-r}=\frac{10}{1-\frac{2}{5} } =\frac{50}{3}$

Given this table of values, what is the value of f(14)?

Vikentia [17]

Answer:

f(14) = 14.6

Step-by-step explanation:

Form the table attached,

Values of 'x' represent the points on the x-axis of the graph of the given function 'f'.

Similarly, values of 'y' represent the points on the y-axis of the graph.

For every input value of x we get an output value 'y'.

f(10) = -12

f(-16) = 15.6

f(14) = 14.6

f(-18) = 14

Therefore, from the given table output value of f(14) will be 14.6
