What is the explicit formula for this sequence?

Mathematics

<em>Greetings from Brasil...</em>

With the recursive formula, lets build the sequence:

A1 = 4

A2 = A1 - 7

A3 = A2 - 7

A4 = A3 - 7

A5 = A4 - 7

(...)

But pay attention to A3....

A3 = A2 - 7   but  A2 = A1 - 7 , so rewriting A3

A3 = (A1 - 7) - 7 ⇒ A3 = A1 + 2.(- 7)

A4 = A3 - 7 ⇒ A4 = [(A1 - 7) - 7] - 7 = A1 + 3.(- 7)

A5 =  {[(A1 - 7) - 7] - 7} - 7 = A5 + 4.(- 7)  

so

<h3>An = A1 + (n - 1).(- 7)</h3>

Hi! I hope this is correct please inform me if this is incorrect :)

3a - 2a + 1>2.

a = 2 will have

ANY others I did not include in a = 1 :)

Please once again tell me if this is incorrect.

A school cafeteria uses 10
gladu [14]

Using proportions, it is found that there are 5 cups of milk in each bowl of chocolate pudding.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The cafeteria used 10 quarts for 8 bowls, hence the number of quarts per bowl is:

10/8 = 1.25

Each quart has 4 cups, hence the number of cups is:

4 x 1.25 = 5 cups.

Can somebody answer this?
allsm [11]

Let us find the area of the triangle first.

6 x 8 / 2 = 24 ft²

Now we can do the semi circle. Note that it is a semi circle and not a circle.

1/2π(4²) = 8π = 25.12 ft²

Add the areas up to find the area for the figure.

24+25.12 = 49.12 ft²
