Answer:

a_{15}=-268,435,456

Step-by-step explanation:

First, find what factor each term is multiplied by to get to the next. To do this, divide the second term by the first, the third term by the second, etc

4\div-1=-4\\-16\div4=-4\\64\div-16=-4

The common factor is 4. Using that, you can now write the equation for the geometric sequence in the form of:

a_n=a_1x^{n-1}

It looks scarier than it is. aₙ is the nth term in the sequence, x is the factor, and n is the index in the sequence, that's all it is.

Plug in the information we have to get the equation for this sequence:

a_n=(-1)(-4)^{n-1}

Then, you can solve for the 15th term:

a_{15}=(-1)(-4)^{15-1}\\a_{15}=(-1)(-4)^{14}\\a_{15}=(-1)(268,435,456)\\a_{15}=-268,435,456

Basically, just raise the scale factor to the power of the term you want minus 1, then multiply that by the first number.

The difference between a number b and 7.4 is -6.8
Lera25 [3.4K]

Hello from MrBillDoesMath!

Answer:

b = 0.6


Discussion:

The question can be written as

b - 7.4 = -6.8  =>           (now add 7.4 to each side)

b - 7.4 + 7.4 = -6.8 + 7.4 =>       ( note: -7.4 + 7.4 = 0)

b = 0.6

Thank you,

MrB

What number will the function return if the input is 15.4?
wlad13 [49]

The rule of the function is to multiply the input by 3, since one yard is equal in length to three feet.

So, if the input is 15.4, the output will be

f(x)=3x \implies f(15.4)=3\cdot 15.4 = 46.2

Helpppppp show your work
Tpy6a [65]

Answer:

-5/3

Step-by-step explanation:

Do PEMDAS

8 - 11 = -3

-3 ^ 3 = -27

-(-27) = 27

I-14I = 14

3 x 14 = 42

27 - 42 = -15

2^4 = 16

16 - 7 = 9

-15/9 = -5/3

16 POINTS!!! HELP ASAP
nadya68 [22]

Answer:

The answer is 358.01

Step-by-step explanation:

Given:

3\times 10^{2}+5\times 10^{1}+8\times 10^{0}+1\times \frac{1}{10^{2}}

Now, to solve first we crack the power notation then multiply and then do the addition:

3\times 100+5\times 10+8\times 1+1\times \frac{1}{100}

(The value of 10^{1} is 10 and the value of 10^{0} is 1.)

=300+50+8+\frac{1}{100}

=300+50+8+0.01

=358.01.

Therefore, the answer is 358.01 .
