Given the sequence 1/2 ; 4 ; 1/4 ; 7 ; 1/8 ; 10;.. calculate the sum of 50 terms

Answers

Hint :-

Break the given sequence into two parts .Notice the terms at gap of one term beginning from the first term .They are like [tex]\dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] . Next term is obtained by multiplying half to the previous term . Notice the terms beginning from 2nd term , [tex]4,7,10,13[/tex] . Next term is obtained by adding 3 to the previous term .

Solution :-

We need to find out the sum of 50 terms of the given sequence . After splitting the given sequence ,

[tex]\implies S_1 = \dfrac{1}{2},\dfrac{1}{4},\dfrac{1}{8}[/tex] .

We can see that this is in Geometric Progression where 1/2 is the common ratio . Calculating the sum of 25 terms , we have ,

[tex]\implies S_1 = a\dfrac{1-r^n}{1-r} \\\\\implies S_1 = \dfrac{1}{2}\left[ \dfrac{1-\bigg(\dfrac{1}{2}\bigg)^{25}}{1-\dfrac{1}{2}}\right] [/tex]

Notice the term [tex]\dfrac{1}{2^{25}}[/tex] will be too small , so we can neglect it and take its approximation as 0 .

[tex]\implies S_1\approx \cancel{ \dfrac{1}{2} } \left[ \dfrac{1-0}{\cancel{\dfrac{1}{2} }}\right] [/tex]

[tex]\\\implies \boxed{ S_1 \approx 1 }[/tex]

[tex]\rule{200}2[/tex]

Now the second sequence is in Arithmetic Progression , with common difference = 3 .

[tex]\implies S_2=\dfrac{n}{2}[2a + (n-1)d] [/tex]

Substitute ,

[tex]\implies S_2=\dfrac{25}{2}[2(4) + (25-1)3] =\boxed{ 908} [/tex]

Hence sum = 908 + 1 = 909

f(x)=2+|x-3| for all x than the value of the derivative of x=3 is

Answers

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.

Susan is choosing tween two cell phone plans that offer the same amount of free minutes.
Plan A charges $29.99 per month with additional minutes costing $0.45
per minute.
Plan B charghes $39.99 a month with addtional minutes costing $0.40 per minute. If the equation for Plan A is
0.45x + 29.99 and the equation for plan E
is 0.40x+ 39.99, then how many addtional minutes, x, will it take for the two plans to cost the same?

Answers

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

f(x) = x³ + 19x² + x + 19

Step-by-step explanation:

Zeros: -19 , -i, complex conjugate root: +i

Function: (x+19)(x+i)(x-i) = 0

(x + 19) (x² - i²) = (x + 19) ( x² + 1) = x³ + 19x² + x + 19

f(1) = 1 + 19 + 1 +19 = 40

A company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50

Based on this information, which graph best shows this relationship between the cost y, and the number of cubic yards, X?​

Answers

The bottom one of the right hand side.

50:1= 25:0.5

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.

Given that, a company charges a delivery fee of $50 to deliver plotting soil and each cubic yard of plotting soil costs $50.

What is graph?

In mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related".

Let the total cost be y and the number of cubic yards be x.

Now, the equation to represent the given situation is y = 50+50x

By substituting x = 0, 1, 2, 3, 4, 5,....we get

y = 50+50(0) = 50

y = 50+50(1) = 100

y = 50+50(2) = 150

y = 50+50(3) = 200

y = 50+50(4) = 250

So, the coordinates to plot the graph are (0, 50), (1, 100), (2, 150), (3, 200) and (4, 250) and so on.

The obtained coordinate points to plot the graph are matching with graph A. Therefore, option A is the correct answer.
