Find 10th term of a geometric sequence whose first two terms are 2 and -8. Please answer!!

The 10th term is -524,288

Step-by-step explanation:

The general format of a geometric sequence is:

In which r is the common ratio and is the previous term.

We can also use the following equation:

In which is the first term.

The common ratio of a geometric sequence is the division of the term by the term

In this question:

10th term:

The 10th term is -524,288

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
