Write the explicit formula for the geometric sequence. Then find the fifth term in the sequence.

Blababa [14]

Sequence: -4, 8, -16

rate of increase: -16/8 = -2

If you make A1 the first term in the sequence you must use (n-1) in the explicit formula. If you go backwards in the sequence to find A0 = 2 then you would use n.

The don't have A0 = 2 listed as an option so we use A1 = -4 and (n-1) terms.

An = -4(-2)^(n-1)

Solving for the 5th term A5, use n = 5

A5 = -4(-2)^(5-1)
A5 = -4(16)
A5 = -64

So the answer is B.

2.1.43 A particular hybrid car travels approximately 235 mi on 5 gal of gas. Find the amount of gas required for a 705-mi trip.

o-na [289]

Answer: 15 gallons of gas is required for a 705 miles trip.

Step-by-step explanation:

Since we have given that

Number of miles in a trip = 235 miles

Number of gallon of gas is needed = 5

We need to find the amount of gas required for 750 miles trip.

Since there is direct variation, as for increase in number of miles, amount of gas must be increased.

According to question, it becomes,

$\dfrac{235}{5}=\dfrac{705}x}\\\\47=\dfrac{705}{x}\\\\47x=705\\\\x=\dfrac{705}{47}\\\\x=15\ gallons$

Hence, 15 gallons of gas is required for a 705 miles trip.

Find the degree of this polynomial? <br> 13-4ab+5a^3b

Anastasy [175]

Let's take a peek of each term, to be specific, the exponent of the variables only, to see what degree each term is

$\bf 13-4ab+5a^3b\quad 
\begin{cases}
13\impliedby \textit{no variable, degree is 0}\\
4ab\to 4a^1b^1\impliedby \textit{1+1, degree is 2}\\
5a^3b\to 5a^3b^1\impliedby\textit{3+1, degree is 4}
\end{cases}$

so...which term has the highest degree? well, that one, is the degree of the polynomial
