The diameter of the earth is about 7900 miles. The diameter of Jupiter is about 88,800 miles, approximately 11 times that of the
jeka94
<span>We know that the surface of a sphere is: S = 4 * pi * r^2 The surface of Earth is : Se = 4 * 3.1416 * (7900/2)^2 = 196,066,797.51 And the Jupiter is : Sj = 4 * 3.1416 * (88800/2)^2 = 24,772,840,374.32 So the surface of Jupiter is around 11^2 times bigger than the Earth</span>

Determine how many terms of the following convergent series must be summed to be sure that the remainder is less than 10 Supersc
algol13

Answer:

You need to sum at least 5000 terms

Step-by-step explanation:

Remember what the estimation theorem for alternating series says.

Given a series

s = \sum\limits_{n=0}^{\infty} (-1)^n a_n

An upper bound for the error of the series R_n  is a_{n+1} so

R_n = |s-s_n| \leq a_{n+1}

For this case you want

\frac{1}{2n+1}  \leq \frac{1}{10^4}\\10^4 \leq 2n+1\\(10^4-1 )/2 \leq n

(10^4-1 )/2 is approximately 5000. So you must sum at least 5000 terms.

How will the volume of a prism change if its height is multiplied by a scale factor of 4?
Fynjy0 [20]

Answer:

It will double in size, as M x M x M x M  is simply just 3 changeable values. When we change 4 numbers of a prism (3 changed values ) to all 4 we have a S4 value to the volume, But we didnt do this, applying x 4 to either measurement it can only increase the volume by x 2. We had a one change value SF4 so we have SF 2= double. That means if we have two change value value SF4 we have 3 = 3 x total  increase, if we have a three input change by SF4 we can increase size to 4x total increase.
