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]

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.

Step-by-step explanation:

To calculate how long it will take John to recover his investment, we need to divide the cost of the degree by the difference in income between the two options.

$10,000 / ($35,000 - $20,000) = $10,000 / $15,000 = 0.67 years or 0.67*12 = 8 months.

So, it will take John 8 months to recover his investment if he goes to school.

The solution is Option A.

The coordinate of the triangle after the translation is given by A' ( 0 , -3 ) with 4 units right and 4 units down

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the coordinate of the triangle be represented as A

Now , the coordinate A = A ( -4 , 1 )

Now , the coordinate of the triangle after translation is A' ( 0 , -3 )

when there is a translation of the coordinate A by 4 units to the right , we get

A to 4 units right = A ( -4 + 4 , 1 )

The new coordinate of A = A ( 0 ,  1 )

Now , A to 4 units down , we get

The coordinate of A' = A' ( 0 , 1 - 4 )

The coordinate of A' = A' ( 0 , -3 )

Answer:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)=45[/tex]

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

Step-by-step explanation:

When calculating composite functions, work from the inside out.

Given composite function:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)[/tex]

First use the graph to find f(1):

[tex]\implies f \left( g \left( f \left( 1 \right) \right) \right)= f \left( g \left(-4\right)\right)[/tex]

Now use the graph to find g(-4):

[tex]\implies f \left( g \left(-4\right)\right)=f(-6)[/tex]

As the graph does not show the value for f(x) when x = -6, we need to use the equation:

[tex]\implies f(-6)=(-6)^2-2(-6)-3=45[/tex]

Therefore:

[tex]f \left( g \left( f \left( 1 \right) \right) \right)=45[/tex]

------------------------------------------------------------------------------

Given composite function:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)[/tex]

First use the graph to find g(0):

[tex]\implies g \left( f \left( g \left( 0 \right) \right) \right)=g \left( f \left( -2 \right) \right)[/tex]

Now use the graph to find f(-2)

[tex]\implies g \left( f \left( -2 \right) \right)=g \left(5 \right)[/tex]

Finally, use the graph to find g(5):

Therefore:

[tex]g \left( f \left( g \left( 0 \right) \right) \right)=3[/tex]

We had to use the equation on the first problem as the graph does not show the value of function f(x) when x = -6.

The vectors generated by means of operations with canonical vectors:

Herein we find three canonical vectors, one for each orthogonal axis, from which we need to perform operations to generate new vectors. There two fundamental operations:

Vector sums

(a, b, e) + (c, d, f) = (a + c, b + d, e + f)

Vector multiplication by a scalar

α · (a, b, c) = (α · a, α · b, α · c)

Where:

If we know that U = (5, 0, 0), V = (0, 5, 0) and W = (0, 0, 5), then the following operations are below:

Case 1

U + V + 2 · W

(5, 0, 0) + (0, 5, 0) + 2 · (0, 0, 5)

(5, 0, 0) + (0, 5, 0) + (0, 0, 10)

(5 + 0 + 0, 0 + 5 + 0, 0 + 0 + 10)

(5, 5, 10)

Case 2

U + T = V

T = V - U

T = (0, 5, 0) - (5, 0, 0)

T = (0 - 5, 5 + 0, 0 + 0)

T = (- 5, 5, 0)

Case 2b

R = U + V + W

R = (5, 0, 0) + (0, 5, 0) + (0, 0, 5)

R = (5 + 0 + 0, 0 + 5 + 0, 0 + 0 + 5)

R = (5, 5, 5)

Case 3

T - 2 · R

(- 5, 5, 0) - 2 · (5, 5, 5)

(- 5, 5, 0) + (- 10, - 10, - 10)

(- 5 - 10, 5 - 10, 0 - 10)

(- 15, - 5, - 10)

Case 3b

S = U + W

S = (5, 0, 0) + (0, 0, 5)

Answer:

The domain of a function is the set of all input values (x-values) for which the function produces a valid output (y-value). In the case of the function H(x) = x+2/x^2+4x+4, we need to find the values of x for which the denominator x^2+4x+4 is not equal to zero.

x^2+4x+4 = 0

(x+2)^2 = 0

The denominator is always non-zero as the square of any real number is always positive. Therefore, the function H(x) = x+2/x^2+4x+4 is defined for all real values of x. Therefore, the function H(x) does not have any values that are not in its domain.

3y = 4x + 2 is a linear equation that satisfies the graph.

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Few coordinates of a linear function to make the equation of line we need only two coordinates.

general formula for linear equation is y = mx + c

where, m = slope

c = constant

General formula for slope m = (y₂ - y₁)/(x₂ -x₁)

Since graph passes through the points(3, 6) and (0, 2)

Slope m = (2 - 6)/ (0 - 3)

m = -4/-3 = 4/3

Thus, equation of line will be

y = 4/3x + c

Since the Line passes through (0, ,2 ) these point will satisfy the above equation

2 = 4/3 * 0 + c

=> c = 2

substitute the values

y = 4/3x + 2

3y = 4x +6

Therefore, equation of line that relates with the graph is 3y = 4x + 6.

Answer: An obstacle course is a series of challenging physical obstacles that must be completed in order to finish the course. To find out how many kilometers long the obstacle course is, you need to add up the distance that Caleb runs, jumps crawls, and dribbles.

First, we need to convert the 500 meters to kilometers by dividing it by 1000.

500 meters / 1000 = 0.5 kilometers

Then, we need to add the distance that Caleb crawls through the tunnel, which is 20 meters.

20 meters = 0.02 kilometers

Finally, we need to add the distance that Caleb dribbles the soccer ball, which is 100 meters.

100 meters = 0.1 kilometers

To find the total distance of the obstacle course, we need to add the distance that Caleb runs, jumps, crawls, and dribbles:

0.5 + 0.02 + 0.1 = 0.62 kilometers

So the obstacle course is 0.62 kilometers long.

Answer: 5/8 "=" 10/16

Step-by-step explanation: To compare the fractions 5/8 and 10/16, we need to find a common denominator. In this case, the least common multiple of 8 and 16 is 16.

So, we can write the fractions as:

5/8 = (52)/(82) = 10/16

So the fractions are equal, therefore, the symbol that correctly compares them is = (the equal sign).

Answer: =

Step-by-step explanation:

In order to compare the fractions, we must make sure that the fractions have common denominators. Because 8 is a factor of 16, we will convert 5/8 into a fraction that has a denominator of 16. To do this, we need to multiply the numerator and denominator by the same number, in this case, 2 since that is what multiplies by 8 to get 16. (5/8) * (2/2) = 10/16 (you can just multiply across the top and bottom to solve). Now, we can compare. 10/16 is the same as 10/16, so an = would be the appropriate symbol. Hope this helps!
