Answer:
an= a1 +(n-1)*4
Step-by-step explanation:
a1 = 1, a2 =5, a3 = 9, a4= 13,... an= ?
we see that each term is getting bigger so usually that will happen because of addition or multiplication-in our case add 4 to previous term
a1 = 1,
a2 = a1+(2-1) 4 = 1+4 = 5,
a3 = a1 + (3-1)*4 = a1+8 = 1 + 8 = 9,
a4= a1 + (4-1)*4 = a1 + 12 = 1+12= 13,
...
an= a1 +(n-1)*4
22/32 = 100/x
22x = 100(32)
22x = 3200
x = 3200/22
x = 145.45 ft
Answer:
There are 3,628,800 different ways for the runners to finish.
Step-by-step explanation:
Arrangments of x elements:
The number of possible arrangments of x elements is given by the following formula:

In this question:
10 different runners, which means that the number of different ways that there are for the runners to finish is an arrangment of 10 elements. So

There are 3,628,800 different ways for the runners to finish.
The price elasticity of demand of the pen will be -0.2.
<h3>How to compute the elasticity?</h3>
The demand and supply schedule will be:
Price Qd. Qs
$10. 250. 100
$20. 200. 90
$30. 180. 80
The price elasticity of demand from $1 to $2 will be:
= Percentage change in quantity demanded/percentage change in price
Percentage change in quantity demanded will be:
= (200 - 250)/250 × 100
= -20%
Percentage change in price will be:
= (20 - 10)/10 × 100
= 100%
Therefore, the elasticity of demand will be:
= -20/100
= - 0.2
The value gotten illustrates an inelastic demand.
In order to increase the total revenue, the price can be reduced as it will lead to more sales.

What price change would you recommend to increase TR?
8 - 2x = -8x + 14 <em>subtract 8 from both sides</em>
-2x = -8x + 6 <em>add 8x to both sides</em>
6x = 6 <em>divide both sides by 6</em>
<h3>x = 1</h3>
