Answer:

An arithmetic sequence has a constant difference between each term.

For example: 2,4,6,8,10,12,…

We can see clearly that all the terms differ by +2.

We call this the common difference, d.

A geometric sequence has a constant ratio (multiplier) between each term.

An example is: 2,4,8,16,32,…

So to find the next term in the sequence we would multiply the previous term by 2.

This is called the common ratio, r.

These sequences are closely related as they both have the same first term, but I hope you can see how different they become if they have a common difference or a common ratio.

We can create a decreasing arithmetic sequence by choosing a negative common difference.

Similarly, a decreasing geometric sequence would have a common ratio of less than 1.

Find x and y 30 points
Vika [28.1K]

Since the two triangles are similar

\frac{5 + x}{5}  =  \frac{7 + y}{7}  =  \frac{10}{8}  \\ \implies \frac{5 + x}{5}  =  \frac{10}{8}  \\ \implies x =  \frac{50}{8}  - 5 =  \frac{50 - 40}{8}  =  \frac{10}{8}   =  \frac{5}{4} \\  \therefore x =   \frac{5}{4}

Also,

\\ \frac{7 + y}{7}  =  \frac{10}{8}  \\ \implies y =  \frac{70}{8}  - 7 =  \frac{70 - 56}{8}  \\  \therefore y =   \frac{14}{8}  =  \frac{7}{4}

A music store buys a trumpet for $80. They want to make a 35% profit. How much are they going to increase the price?
elena-s [515]

Answer:

They should increase their price by $28.

Step-by-step explanation:

First find out what 35% of 80 is. Do so by multiplying 80 by 35% in its decimal form - .35.

80*.35=28.

This means that they have to increase their price by at least 28 dollars to make a profit.

The new price of the instrument should be $108 - $80 increased by 35%.

Hope this helps :)
