Which of the following is not one of the three geometric means between 5 and 80? a.30
b.10.
c.40
d.20​

The reason for this geometric progression is 2

The three interpolated terms are:

10 , 20 and 40.

STEP BY STEP EXPLANATION :

5 , ___ , ___ , ___ , 80

An = A1 • [Q^(n - 1)]

80 = 5 • [Q^(5 - 1)]

80 = 5 • [Q^4]

5 • [Q^4] = 80

[Q^4] = 80/5

[Q^4] = 16

Q = \mathsf{\sqrt[4]{16}}

4

16

Q = 2

Ok

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
