5. Luis found a new text messaging plan which will charge him $2.00 for 80 messages. Using this
plan, how much would he pay for 900 text messages in one month?

The first five terms of a geometric sequence are 5, 10, 20, 40, 80.

A geometric sequence is also known as Geometric Progression (GP) is a non-zero numerical series whereby each term succeeding the very first is determined by multiplying the preceding one by a fixed, non-zero value designated as the common ratio.  

It can be expressed by using the formula:

[tex]\mathbf{a_n = ar^{n-1}}[/tex]

where;

Given that;

∴

The second term of the sequence is:

[tex]\mathbf{a_2 = 5 \times 2^{2-1}}[/tex]

[tex]\mathbf{a_2 = 5 \times 2^{1}}[/tex]

[tex]\mathbf{a_2 = 10}[/tex]

The third term of the sequence is:

[tex]\mathbf{a_3 = 5 \times 2^{3-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{2}}[/tex]

[tex]\mathbf{a_2 = 20}[/tex]

The fourth term of the sequence is:

[tex]\mathbf{a_4 = 5 \times 2^{4-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{3}}[/tex]

[tex]\mathbf{a_4 = 40}[/tex]

The fifth term of the sequence is:

[tex]\mathbf{a_5 = 5 \times 2^{5-1}}[/tex]

[tex]\mathbf{a_3 = 5 \times 2^{4}}[/tex]

[tex]\mathbf{a_4 = 80}[/tex]

Answer:

[tex]x = 56.02 \degree[/tex]

Step-by-step explanation:

To find the angle you have to use sin rule

[tex] \sin( \theta) = \frac{opposite}{hypotenuse} [/tex]

Let the unknown angle be x

[tex] \sin(x) = \frac{o}{h} \\ \sin(x) = \frac{34}{41} \\ \sin(x) = 0.8292 \\ x = \sin ^{ - 1} 0.8292 \\ x = 56.02 \degree[/tex]

Answer:

First Game: 65 points

Second Game : 65 points

Third Game : 59 points

Step-by-step explanation:

Average = sum of values/number of values

The number of values = 3, an d average = 63

63 = x/3

63 * 3 = x

189 = x

Now 189 is the sum of points over two games.

Their first two games are worth the same, so lets call that s +s = 2s

Their 3rd game is worth 6 less points than s, so s-6

let's add up all the terms:

2s + (s - 6) = 3s - 6

Solve:

3s - 6 = 189

3s = 195

s = 65

The first two games are worth 65, and the third game is worth 65 - 6 = 59.

-Chetan K

Answer:65, 65 and 59

Step-by-step explanation:

If represented by x and y, (2x+y)/3=63

So 2x+y=189

So if x=y+6

Put the value of x into the equation

2x + y = 189

2(y + 6) + y = 189

2y + 12 + y = 189

3y = 189 - 12

3y = 177

y = 177/3

y = 59

Therefore, x = y + 6 = 59 + 6 = 65

The answers are :

a) The derivative of this function at the point (3,256) is -96.

b) The speed at which the supply bundle is falling is negative.

What is derivative ?

Derivative is the slope of the graph of function or the slope of the tangent line at a point.

A function is given which is h(t) = 400 - 16t².

Here , h(t) gives the height of the supply bundle in feet , t seconds after it is dropped from a height of 400 feet.

a)

We have to find out the derivative of the given function at a point (3,256).

h'(t) = [tex]\frac{d}{dt}[/tex] (400 - 16t²)

h'(t) = 0 - 2 × 16 × t

h'(t) = -32 t

This function at (3,256) so , value of t is 3.

h'(t) = -32 × 3

h'(t) = -96

b)

Speed = -32 t

So , the speed at which the supply bundle is falling is negative. With increase in value of t it will keep decreasing.

Therefore , the answers are :

a) The derivative of this function at the point (3,256) is -96.

b) The speed at which the supply bundle is falling is negative.
