What is the next fraction in each of the following patterns?1/40,4/40,9/40,16/40,25/40...?

1 answer:

5 0

Let
a1=1/40
a2=4/40
a3=9/40
a4=16/40
a5=25/40
a6=?

we know that
a2-a1=4/40-1/40----> 3/40
a3-a2=9/40-4/40-----> 5/40
a4-a3=16/40-9/40----> 7/40
a5-a4=25/40-16/40---> 9/40

the difference is
3/40,5/40,7/40.9/40,....
3/40+[2/40]---> 5/40
5/40+[2/40]---> 7/40
7/40+[2/40]---> 9/40

the next will be
9/40+[2/40]-----> 11/40
so
the next term is 25/40+[11/40]------> 36/40

the answer is
36/40

Komok [63]

Solution:

we have been asked to find a function for the given sitatution

The given situation is

A movie store sells DVDs for $11 each. what is the cost C of n DVDs.

Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.

Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.

......................................................................................................................

.......................................................................................................................

Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.

Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.

Hence the correct option is C=11n, Discrete.

A rancher has 2 comma 200 feet of fencing to enclose a rectangular pig pen. However, one side of the pen lies along a river and

DiKsa [7]

Answer:

$A = 2200x - 2x^2$

Step-by-step explanation:

Let's x be the length of the side that is NOT the same as the side along the river (or in opposite). From the fencing perimeter of 2200ft we can calculate the other side y of the rectangular:

y = 2200 - 2x

The area A of the pen would be the product of the 2 sides

$A = xy = x(2200 - 2x) = 2200x - 2x^2$
