Find the tenth term of the geometric sequence, given the first term and common ratio.

Natalija [7]

Answer:

$a_{10}=\dfrac{1}{128}$

Step-by-step explanation:

In the geometric series:

$a_1=4\\ \\r=\dfrac{1}{2}$

The nth term of the geometric sequence can be calculated using formula

$a_n=a_1\cdot r^{n-1}$

In your case, n = 10, then

$a_{10}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^{10-1}\\ \\=4\cdot \left(\dfrac{1}{2}\right)^9\\ \\=2^2\cdot \dfrac{1}{2^9}\\ \\=\dfrac{1}{2^{9-2}}\\ \\=\dfrac{1}{2^7}\\ \\=\dfrac{1}{128}$

A shop has 15% sale. Originally a computer cost £275. How much does the computer cost in the sale?

Kaylis [27]

Answer:

= 233.75

Step-by-step explanation:

To find the discount, we multiply the original price by the percent off

discount = 275* .15

= 41.25

To get the sale price, take the original price and subtract the discount

sale price = 275-41.25

= 233.75
