Find a2 and a3 for the geometric sequence 4, a2, a3, 108.

LekaFEV [45]

9514 1404 393

Answer:

a2 = 12

a3 = 36

Step-by-step explanation:

Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...

a2 = 4r

a3 = (a2)r = 4r^2

108 = (a3)r = 4r^3

27 = r^3 . . . . . . . . . . . divide by 4

3 = r . . . . . . . . . . cube root

a2 = 4(3) = 12

a3 = 12(3) = 36

write a word problem that you can represent with the expression 8÷2/3. draw a model and use equation to show the solution

Mariana [72]

Answer:

The word problem is " In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there".

Step-by-step explanation:

The given expression is

$8\div \frac{2}{3}$

We need write a word problem which is solved by the above expression.

Word problem : In a class there are 8 boys and these are 2/3rd parts of total students. How many students are there.

Solution:

Let the total number student be x.

$x\times \frac{2}{3}=8$

Divide both sides by 2/3.

$x=\dfrac{8}{\frac{2}{3}}$

$x=\dfrac{8\times 3}{2}$

$x=12$

Therefore, the total number of students is 12.
