Step-by-step explanation:

[tex] a_n = 3^{n - 1} [/tex]

You need the first 4 terms, so let n = 1, and evaluate the expression. Then do the same for n = 2, n = 3, and finally n = 4.

n = 1

[tex] a_1 = 3^{1 - 1} = 3^0 = 1 [/tex]

n = 2

[tex] a_2 = 3^{2 - 1} = 3^1 = 3 [/tex]

n = 3

[tex] a_3 = 3^{3 - 1} = 3^2 = 9 [/tex]

n = 4

[tex] a_4 = 3^{4 - 1} = 3^3 = 27 [/tex]

Answer:

D. 10

Step-by-step explanation:

The chord is bisected as shown by the perpendicular lines and right angle, so both segments are 6.

Draw a radius from the center to the end of the chord to create a right triangle. 8 and 6 are the legs, use pythagorean theorem to find the length of the segment you drew because its the hypotenuse.

8^2+6^2=x^2

64+36

100

square root of 100 is 10

So, 10 is the length of the segment. Both the x segment and the 10 segment are radii because they are draw from the center to a point on the circle.

They are equal.

x=10

ANSWER

10

EXPLANATION

The value of x is the radius of the circle.

The radius of the circle is also the hypotenuse of the right triangle formed by the chord, the radius and the segment bisecting the chord through the center.

We apply the Pythagoras Theorem to obtain:

[tex] {x}^{2} = {8}^{2} + {6}^{2} [/tex]

[tex] {x}^{2} = 64 + 36[/tex]

[tex] {x}^{2} = 100[/tex]

Take positive square root

[tex]x = \sqrt{100} [/tex]

[tex]x = 10[/tex]

Answer:

Step-by-step explanation:

One

Since you are asked to solve this using a graphing tool, here is the results as graphed by Desmos.

The point you want is (3,2)

The answer is 2.

Two

Multiply the second equation by 2

2[0.5x - y = 10]

x - 2y = 20              Add the first equation

x + 2y = 16      

2x = 36                   Divide by 2

x = 36/2

x = 18

Since this is all you are asked for, x = 18 is the answer.

Three

y is an exterior angle.

It is the sum of the two (given) remote interior angles.

y = 35 + 105

y = 140

x and y are supplementary (they add up to 180o

x + y = 180

x + 140 = 180

x = 180 - 140

x = 40

y - x = 140 - 40

y - x = 100        

Answer:

"Third graph" in the attached picture.

Step-by-step explanation:

The correct graph would be the "intersection" of the lines:

y = -3, and

x - y = 8

We know, y = -3 is a horizontal line at y = -3 and the next is a line. By looking at the first equation, we can eliminate 2 graphs and thus find the correct graph.

y = -3 is a horizontal line at y = -3, the first graph has the line y = 3, so we can eliminate this even without looking at the graph of 2nd equation.

The second graph has a vertical line, no horizontal, so we can eliminate this choice as well.

The third graph has y = -3 (horizontal line at y = -3) and thus this is the correct choice. Also, x - y = 8 means y = x -8, which is the other graph shown.

correct answer is the "third graph".

Answer: last option.

Step-by-step explanation:

 The equation of the line in slope-intercept form is:

[tex]y=mx+b[/tex]

Where m is the slope and b the intersection with the y-axis.

The line [tex]y=-3[/tex] is a line with slope 0 that cut the y-axis at (0,-3)

Solve for y from the second equation:

[tex]x-y=8\\x-8=y[/tex]

The line [tex]y=x-8[/tex] is a line with slope 1 that cut the y-axis at (0,-8)

You can identify these lines in the last graph, where the point of intersection between them is the solution of the system of equations.

Answer:

-240°, -600°

Step-by-step explanation:

Coterminal angles are angles that land in the same spot around a circle.

So, that means they do full turns of the circle to reach each other.

To find coterminal angles of a given angle (here 120 degrees), you add or subtract 360 (the number of degrees in a full circle).  That can go in both positive or negative directions.

So, from 120 degrees, let's find the coterminal angle that is 1 rotation above and one rotation below:

120 + 360 = 480

120 - 360 = -240

You see that 480 isn't among the possible answers, so one part of the answer is -240.  If you subtract another 360 degrees, you end up with -600 degrees... so the answer is -240°, -600°

Answer:

Option B.

Step-by-step explanation:

If a quadratic equation is defined as

[tex]ax^2+bx+c=0[/tex]         .... (1)

then the quadratic formula is

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

The given equation is

[tex]10x^2=6+9x[/tex]

It can rewritten as

[tex]10x^2-9x-6=0[/tex]            .... (2)

On comparing (1) and (2) we get

[tex]a=10,b=-9,c=-6[/tex]

Using quadratic formula we get

[tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(10)(-6)}}{2(10)}[/tex]

[tex]x=\dfrac{9\pm \sqrt{81+240}}{20}[/tex]

[tex]x=\dfrac{9\pm \sqrt{321}}{20}[/tex]

Therefore, the correct option is B.

Answer:

Total = Principal * (1 + rate) ^ years

We have to solve this for years:

Years = {log(total) -log(Principal)} ÷ log(1 + rate)

Jocelyn: Years = {log(total) -log(1,600)} ÷ log(1.025)

Marcus: Years =  {log(total) -log(400)} ÷ log(1.054)

We know the years must be equal but we won't know the total so we'll call that "x".

[log(x) -log(1,600)] ÷ log(1.025) = [log(x) -log(400)] ÷ log(1.054)

Time is about 49 Years 8 Months and total is about 5,454.00

Answer:

i think it should be tan2x = 24/7, i hope i am not wrong

Step-by-step explanation:

If sin x = -3/5 and x is in quadrant 3, then tan 2x = 24/7.

Given:

[tex]$Sin x = \frac{-3}{5}[/tex]

To estimate cos x by identity

[tex]$Cos^{2} x=1-Sin^{2} x[/tex]

[tex]$Cos^{2} x =1-\frac{9}{25}[/tex]

[tex]$=\frac{16}{25}[/tex]

cos x = ±(4/5)

Since x exists in Quadrant III, then cos x exists negative.

tan x = Sin x/Cos x

= (−35)/(−54) = 3/4

By using the trigonometric identity, we get

tan 2x = 2 tan x / [tex]$1-tan^{2} x[/tex]

tan 2x = (6/4) / (1−9/16)

= (6/4)(16/7)

= 24/7

Therefore, tan 2x = 24/7.

Answer:

first choice: (x, y) ------> (x + 3, y - 2)

Step-by-step explanation:

The x-coordinate started as 4. Then it became 7. To change from 4 to 7, you add 3. The rule for x is to add 3.

The y-coordinate started as -8. Then it became -10. To go from -8 to -10, you subtract 2. The rule for y is to subtract 2.

Look at the choices, and pick the one that adds 3 to x and subtract 2 from y.

The answer is the first choice: (x, y) ------> (x + 3, y - 2)

Answer:

66

Step-by-step explanation:

x is the second angle

3x is the first angle

x+70 is the third angle

x+3x+x+70=180

5x = 110

x= 22

first angle: 3x = 3*22 = 66

Answer:

Second angle: 22°

And the other angles are:

First angle: 66°

Third angle: 92°

Step-by-step explanation:

Let be:

[tex]x[/tex] the measure of the second angle.

[tex]3x[/tex] the measure of the first angle.

[tex](x+70)[/tex]: the measure of the third angle.

Then, knowing that the sum of the interior angles of a triangle is 180 degrees, you can write this expression and solve for "x",to calculate the measure of the second angle:

[tex]x+3x+(x+70)=180\\5x+70=180\\5x=180-70\\\\x=\frac{110}{5}\\\\x=22\°[/tex]

You can also know that:

First angle:

[tex]3x=2(22\°)=66\°[/tex]

Third angle:

[tex]x+70\°=22\°+70\°=92\°[/tex]

For this case we have that by definition, to move from Celsius to Fahrenheit we must apply the following formula:

[tex]F = \frac {9} {5} C + 32[/tex]

Example, we want to convert 45 degrees Celsius to Fahrenheit:

[tex]F = \frac {9} {5} (45) +32\\F = 9 * 9 + 32\\F = 81 + 32\\F = 113[/tex]

Thus, 45 degrees Celsius equals 113 degrees Fahrenheit.

ANswer:[tex]F = \frac {9} {5} C + 32[/tex]

For anyone who still needs this:

1. Multiply your Celsius measurement by 9/5 (or 1.8)

Answer:

68.2 feet

Step-by-step explanation:

The angle of elevation, the one from the ground up, is given as 33 degrees.  If Kari is 105 feet from the tree, that serves as the measure of the base of the right triangle.  We are looking for the height of the tree, which is the side opposite the angle.  What we have, then, is the angle (33 degrees), the side adjacent to the angle (105 ft), and we are looking for the side opposite the angle (x).  What we need to use is the tangent ratio, which relates the side opposite the angle to the side adjacent to the angle, as follows:

[tex]tan33=\frac{x}{105}[/tex]

To solve for x we multiply both sides of the equation by 105 to get 105tan33°=x.  Plug that into your calculator in degree mode to get 68.18779729.  Round from there to get 68.2 feet.

I tried to personal message you but it didn't work. I have a question about your question it says "making both at the same rate". My question is both what?

Answer: The answer is 0.04

Step-by-step explanation:

To determine the height of a triangle-shaped density curve spanning from 0 to 50 years, we use the fact that the area under the density curve must equal 1. The equation (50 * height) / 2 = 1 allows us to solve for the height, which is 0.04 on the probability density scale.

To determine the height of the triangle representing a density curve for possible ages, we need some information about the properties of that triangle and density curves in general. A density curve shows how the proportion of a particular measurement (in this case, ages) is spread out over a range. The area under a density curve must equal 1 (or 100%) since it represents the total probability distribution.

In this scenario, we have a triangle as a density curve stretching from 0 to 50 years, which suggests that 0 and 50 are the bounds of our variable (age). The base of the triangle spans these 50 years. If we assume a right-angled triangle for simplicity's sake (which isn't specified in the question but is a common assumption), then the area of the triangle, which represents the probability, would be (base * height) / 2.

To ensure that the total area under the curve equals 1, we set up the following equation: (50 * height) / 2 = 1. Solving this equation for height gives us height = 2 / 50, which simplifies to height = 0.04. Therefore, the height of the density triangle is 0.04 on whatever scale is being used for probability density (e.g., per year).

The cost of  chair is [tex]\$260[/tex]

The cost of  a lamp is [tex]\$65[/tex]

The cost of  a table is [tex]\$237[/tex]

Step-by-step explanation:

Let

x----> the cost of  chair

y----> the cost of  lamp

z----> the cost of table

we know that

[tex]x+y+z=562[/tex] ----> equation A

[tex]x=4y[/tex] -----> [tex]y=x/4[/tex] -----> equation B

[tex]z=x-23[/tex] ------> equation C

substitute equation C and equation B in equation A and solve for x

[tex]x+(x/4)+(x-23)=562[/tex]

[tex](9/4)x=562+23[/tex]

[tex](9/4)x=585[/tex]

[tex]x=585*4/9=\$260[/tex]

Find the value of y

[tex]y=260/4=\$65[/tex]

Find the value of z

[tex]z=260-23=\$237[/tex]

Answer:

sinθ = 12/15 -> 4/5

cosθ = 9/15 -> 3/5

tanθ = 12/9 -> 4/3

cscθ = 15/12 -> 5/4

secθ = 15/9 -> 5/3

cotθ = 9/12 -> 3/4

Step-by-step explanation:

The theta is where you would use to identify the numbers for the trig functions. The adjacent side is the one closest to the theta (but not the diagonal line, that is the hypotenuse), and the opposite line is the line next to the adjacent line.

For the first three trig functions, would use the method Soh Cah Toa.

Sin = opp/hypotenus, Cosine = adjacent/hypotenuse, and Tangent = opposite/adjacent. Then, there is cosecant(csc) = hyp/opp, secant = hyp/adj, and cotangent = adj/opp.

[tex]\displaystyle\sum_{n=1}^4\frac1{(n-1)!}=\frac1{0!}+\frac1{1!}+\frac1{2!}+\frac1{3!}[/tex]

and [tex]0!=1[/tex] by definition so that the sum has a value of [tex]\dfrac83[/tex].
