The explicit equation of the function is t(n) = 5 * 8^(n-1)

The function definition is given as:

t(1)=5

t(n+1)=8t(n)

Let n = 1

So, we have:

t(2) = 8t(1)

Divide through by t(1)

t(2)/t(1) = 8

The common ratio of the function is:

r = t(2)/t(1) = 8

The explicit rule is then calculated as:

t(n) = t(1) * r^(n-1)

So, we have:

t(n) = 5 * 8^(n-1)

Hence, the explicit equation of the function is t(n) = 5 * 8^(n-1)

Fully expanding and simplifying an expression means distributing all values and combining like terms.

Distributing

First, the 5 needs to be distributed to the values within the parentheses. Using the distribution property, the 5 can be multiplied by 3y and 2.

Then, just simplify

Combine Like Terms

Now that all values are distributed like terms need to be added together.

The terms 10 and 6 are of the same power and do not have variables. So, they can be added together.

This expression is the most expanded and simplified version.

We conclude that the measure of that angle is 150 degrees.

Notice that  the measure of angle ∠BFE will be equal to:

∠BFE = ∠BFC + ∠CFD + ∠DFE

Where:

∠CFD = 90°

∠DFE = 30°

And we will have that:

∠AFC = 180° - 90° - 30° = 60°

And we know that BF bisects that angle, then:

∠BFC = 30°

So we conclude that:

∠BFE = ∠BFC + ∠CFD + ∠DFE = 30° + 90° + 30° = 150°

We conclude that the measure of that angle is 150 degrees.

Step-by-step explanation:

You want the measure of the angle marked x° in the circle with arcs of 152° and 122° shown.

The arc subtended by the inscribed angle x° will be the measure of the arc that makes up the rest of the 360° circle:

  360° -152° -122° = 86°

The measure of angle x° is half the measure of the subtended arc:

  x° = 86°/2

The distributive property allows you multiply a sum in parenthesis by multiplying each addend separately, then add the products.

Step-by-step explanation:

How to use the distributive law example.

2(x+4) = 16

To use the distributive law in this example multiply 3 by all terms in the parenthesis. Multiply 2 and x, then 2 and 4 to open the parenthesis.

2x+8=16

That is how you use the distributive law.

To continue solving, subtract 8 from both sides.

2x+8-8=16-8

2x=8

Divide 2 from both sides.

2x/2=8/2

x=4

Answer:

The given lines are un-related.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (-8,-55) and (10,89). Whereas, line 2 passes through (9,-44) and (4,-14).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

[tex]$$\begin{aligned}&m_{1}=\frac{89-(-55)}{10-(-8)} \\&m_{1}=\frac{144}{18} \\&m_{1}=8\end{aligned}$$[/tex]

Step 2 of 2

Find the slope of first line.

[tex]$$\begin{aligned}&m_{2}=\frac{-14-(-44)}{4-9} \\&m_{2}=\frac{30}{-5} \\&m_{2}=-6\end{aligned}$$[/tex]

Since, both slopes are neither equal nor reciprocal of each other.

Therefore, the lines are un-related.

The number should be 54, where we can add 36 to get twice the number decreased by 18.

There are only one or two variables in a linear equation. No variable can be multiplied by a number larger than one or used as the denominator of a fraction in a linear equation.

Given that, when we add 36 with a number then it gives twice the number decreased by 18.

Let the number be [tex]x[/tex] .

By using triangle properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

[tex]\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}[/tex]

L ≈ 62.464°

Then, we get the distance between points M and N by the law of the cosine once again:

[tex]MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}[/tex]

MN ≈ 9.8 m
