From the given information we can see:

Use the equation for the sum of the first n terms:

Answer:

[tex]S_7=6554[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{7 cm}\underline{Sum of the first $n$ terms of a geometric series}\\\\$S_n=\dfrac{a(1-r^n)}{1-r}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $r$ is the common ratio.\\\end{minipage}}[/tex]

Given geometric series:

[tex]2-8+32-...+a_n[/tex]

The first term (a) of the sequence is 2:

[tex]\implies a=2[/tex]

To find the common ratio (r), divide consecutive terms:

[tex]\implies r=\dfrac{a_2}{a_1}=\dfrac{-8}{2}=-4[/tex]

To find the sum of the first 7 terms, substitute the found values of a and r into the formula, along with n = 7:

[tex]\implies S_7=\dfrac{2(1-(-4)^7)}{1-(-4)}[/tex]

[tex]\implies S_7=\dfrac{2(1-(-16384))}{5}[/tex]

[tex]\implies S_7=\dfrac{2(16385)}{5}[/tex]

[tex]\implies S_7=\dfrac{32770}{5}[/tex]

[tex]\implies S_7=6554[/tex]

The ordered pair which represents the point of intersection of the system of equations, y = 2x - 5 and y = -2/3x + 3 is: (3, 1).

The solution to a system of equations can be determined by graphing both equations that represent the lines on a coordinate plane. Search for the point where both lines intersect each other.

The point where they intersect each other is the ordered pair that represents the solution of the system of equations.

Given the following system:

y = 2x - 5

y = -2/3x + 3

y = 2x - 5 is the red line in the graph while y = -2/3x + 3 is the blue line.

Both lines intersect at (3, 1). Therefore, the solution to the system is: (3, 1).

Answer:

Not rounded:

1.62 increased by 8% of the value = 1.7496

The actual change:

1.7496 - 1.62 = 0.1296

Rounded off to max. 2 decimal places:

1.62 increased by 8% of the value ≈ 1.75

The actual change:

1.75 - 1.62 ≈ 0.13

Step-by-step explanation:

'Percent (%)' means 'out of one hundred':

8% = 8 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100

8% = 8/100 = 8 ÷ 100 = 0.08

100% = 100/100 = 100 ÷ 100 = 1

The value of the percentage increase = 8% × 1.62

The new value = 1.62 + The value of the percentage increase

The new value =

1.62 + The value of the percentage increase =

1.62 + (8% × 1.62) =

1.62 + 8% × 1.62 =

(1 + 8%) × 1.62 =

(100% + 8%) × 1.62 =

108% × 1.62 =

108 ÷ 100 × 1.62 =

108 × 1.62 ÷ 100 =

174.96 ÷ 100 =

1.7496 ≈

1.75

The actual change =

The new value - 1.62 =

1.7496 - 1.62 =

0.1296 ≈

0.13

The value of the percentage increase =

8% × 1.62 =

8 ÷ 100 × 1.62 =

8 × 1.62 ÷ 100 =

12.96 ÷ 100 =

0.1296 ≈

Step-by-step explanation:

Given the histogram provided, it is not possible to draw a conclusion as it doesn't show any data.

A histogram is a graphical representation of a dataset, showing the frequency of each data point in a specific range. The x-axis shows the range of data points, and the y-axis shows the frequency of each data point. Without the data, it's impossible to draw any conclusion.

In order to draw a conclusion, we need to know the data that the histogram represents, such as the range of temperatures, the frequency of each temperature, and the number of days in the month. Based on that information, we can draw conclusions about the data provided.

The expression 8h + (-7.7d) -14 +5d - 3.3h can be simplified as

4.7h - 2.7d - 14

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power (1). In other words, none of the exponents can be greater than 1.

For example, x² is a variable raised to the second power, but x is a variable raised to the first power.

5 is an example of a constant.

8h + (-7.7d) -14 +5d - 3.3h

Taking like terms

Answer:

P = 5c + 11 , c = 3

Step-by-step explanation:

(a)

the perimeter P) is the sum of the sides.

Note that the 2 sides with a ' dash' through them are congruent

summing the 4 sides

P = c + 5 + 3c - 2 + 10 - 2c + 3c - 2 ( collect like terms )

  = 5c + 11

(b)

equate the expression for P from (a) to 26

5c + 11 = 26 ( subtract 11 from both sides )

5c = 15 ( divide both sides by 5 )

c = 3

The measure of m<1 is 108 degrees from the provided figure.

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Lines are therefore one-dimensional objects, even if they can exist in spaces with two, three, or more dimensions.

From the diagram, we have the following parameters

m<2 = 72 degrees

Required parameters

The measure of angle m<1

From the figure, the sum of the interior angle is equivalent to 180 degrees, that is:

m<1 + m<2 = 180

m<1 = 180 - m<2

m<1 = 180 - 72

m<1 = 108 degrees

Hence the measure of m<1 from the given figure is 108 degrees.

Step-by-step explanation:

The average cost of your item, based on a gross margin of 3%, is $108.20.

The average cost is the cost per unit.

It can be computed as the quotient of the total cost and the number of units.

The gross margin is the percentage difference between the cost of goods sold and the sales revenue.

The gross margin percentage is expressed as a quotient of the sales revenue multiplied by 100.

Selling price = $111.55

Gross margin = 3%

Selling price = 100%

Cost of goods sold = 97% (100 - 3)

Average cost (cost per unit) = Selling Price x Percentage Cost/Selling Price Percentage

$108.20 ($111.55 x 97/100)

Thus, the average cost of the product is $108.20.

By using the fact that the sum of the interior angles must be 180°, we wil see that:

x = 110°.

First, remember that the sum of the interior angles of a triangle is alway equal to 180°.

We also can see that the interior angle that is adjacent to x can be written as:

a = 180° - x

Then the sum of the interior angles will give:

30° + 80° + (180° - x) = 180°

30° + 80° - x = 0

110° - x = 0

110° = x

That is the value of x.

Exponential function is a type of function of the form: f(x) = a(b)^x. It is made up of  3 main parts

a = the starting or initial value

b = the base function

x = the exponents

Considering the given problem,   f(x) = a(b)ˣ

the starting, a = 370

the base = ?

the exponents = year periods

the base is calculated below

form 2012 to 2005 is 7 years hence x = 7

amount inn 2012 = amount in 2005 (b)ˣ

480 = 370 * b⁷

48/27 = b⁷

b = 1.038

this is same as 3.8% increment
