A newborn baby had about 26,000,000,000 cells. An adult has about 4.94 times 10 to the 13 power cells. How many times as many ce
Tom [10]
2.6 • 10^10 = 26,000,000,000
4.94 • 10^13 = 49,400,000,000,000

49,400,000,000,000/26,000,000,000= 1900

And adult had 1900 times more cells than a newborn. Or if you want to put it in scientific notation it would be 1.9 • 10^3

Given the sequence in the table below, determine the sigma notation of the sum for term 4 through term 15. N an 1 4 2 −12 3 36 t
Rzqust [24]

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    \sum_{n=4}^{15} 5(-2)^{n-1}$$  

<h3>What is sequence ?</h3>

Sequence is collection of  numbers with some pattern .

Given sequence

a_{1}=5\\\\a_{2}=-10\\\\\\a_{3}=20

We can see that

\frac{a_1}{a_2}=\frac{-10}{5}=-2\\

and

\frac{a_2}{a_3}=\frac{20}{-10}=-2\\

Hence we can say that given sequence is Geometric progression whose first term is 5 and common ratio is -2

Now n^{th}  term of this Geometric progression can be written as

T_{n}= 5\times(-2)^{n-1}

So summation of 15 terms can be written as

\sum_{n=4}^{15} T_{n}\\\\$\\$\sum_{n=4}^{15} 5(-2)^{n-1}$$

By applying basic property of Geometric progression we can say that sum of 15 terms of a sequence whose first three terms are 5, -10 and 2 is                    \sum_{n=4}^{15} 5(-2)^{n-1}$$

Let P be the set of polynomials. Let a, b, c, and d be elements of P such that band d are non-zero elements of P. Which of the f
lozanna [386]

Answer:

D. The sum is a rational expression.

Step-by-step explanation:

the given expression is  a/b +c/d

so in the question it is given that b and d are non zero values

a/b is rational number and c/d is a rational number

so if both are rational number , so we know that the sum of rational number is also a rational number.

The right option is D. The sum is a rational expression
