Answer:

Step-by-step explanation:

Here a = 8, b = 4 and c = -2.  The discriminant here is b^2 - 4ac, which, when the above coefficients are substituted, results in:

discriminant = (4)^2 - 4(8)(-2), or 16 + 64, or 80.

The solutions are:

      -(4) ± √80         -4 ± 4√5        4(-1 ±√5)        -1 ± √5

n = ------------------ = ----------------- = --------------- = --------------

            2(8)                    16                 4^2                  4

A small cube with side length 6y is placed inside a larger cube with side length 4x^2. What is the difference in the volume of t
Eddi Din [679]
A cube has a volume equal to the cube of its side. For the given statement above, since the small cube has a side of 6y then its volume is equal to 216y^3. For the larger cube with a side length of 4x^2, then its volume is equal to 64 x^6. In other words, the difference in their volume is equal to 64x^6-216y^3

Write an explicit formula for a_na
Masja [62]

Explicit formula for the sequence 29,20,11....... is a_n=38-9n

Given :

term of the sequence 29, 20, 11, ...

We need to find out the formula for the nth term of the given sequence

Lets find out whether the given sequence is arithmetic or geometric

In the given sequence , common difference is 9

20-29=-9\\11-20=-9

we can say difference =-9

General explicit formula

a_n=a_1+(n-1)d

where a1 is the first term

common difference d=-9

substitute the values

a_n=a_1+(n-1)d\\a_n=29+(n-1)(-9)\\a_n=29-9n+9\\a_n=38-9n

Explicit formula for the sequence 29,20,11....... is a_n=38-9n
