Which function describes the sequence 4, 12, 36, 108, ... for n = 1, 2, 3, 4...?

a) f(n) = 2" + 1

b) f(n) = 3n

c f(n) = (n − 1)2 + 3

d) f(n) = 4.3"-1

Answer:[tex]454.019\ ft^2[/tex]

Step-by-step explanation:

Given

Diameter of semi-circle is [tex]d=34\ ft[/tex]

So, its radius is [tex]r=\dfrac{34}{2}=17\ ft[/tex]

Area of semi-circle is [tex]\dfrac{\pi r^2}{2}[/tex]

[tex]\therefore \text{Area of semi-circle is }=\dfrac{\pi r^2}{2}\\\\\Rightarrow A=\dfrac{\pi \cdot 17^2}{2}\\\\\Rightarrow A=454.019\ ft^2[/tex]

Thus, the area of semi-circle is [tex]454.019\ ft^2[/tex]

Answer:

c=26

Step-by-step explanation:

10^2 + 24^2=c^2

100+576=c^2

676=c^2

c=26

Hope I helped, have a nice day :)

Answer:

The Answer is 26

Step-by-step explanation:

to find the hypothenuse you need to use this formula a²+b²=c² so 10x10 is 100 and 24x24 is 576. Add those up and find the square root. √676 is 26.

Answer:

6 and 3

Step-by-step explanation:

let x and y be the 2 numbers with x > y , then

2x + 3y = 21 → (1)

x - y = 3 → (2)

Multiplying (2) by 3 and adding the result to (1) will eliminate y

3x - 3y = 9 → (3)

Add (1) and (3) term by term to eliminate y

5x = 30 ( divide both sides by 5 )

x = 6

Substitute x = 6 into either of the 2 equations and solve for y

Substituting into (1)

2(6) + 3y = 21

12 + 3y = 21 ( subtract 12 from both sides )

3y = 9 ( divide both sides by 3 )

y = 3

The 2 numbers are 6 and 3

Answer:

540 degrees

Step-by-step explanation:

The formula to find the sum of interior angles in any polygon is the following:

[tex]S=180(n-2)[/tex]

Where (n) represents the number of sides in the polygon. In this case, the polygon has (5) sides, therefore substitute (5) in place of (n) and solve;

[tex]S=180(n-2)\\\\S=180(5-2)\\\\S=180(3)\\\\S=540[/tex]

Hello !

Answer:

[tex] \boxed{\sf c= -14} [/tex]

Step-by-step explanation:

We will try to find the value of c that satisfies the equality.

Given equation:

[tex] \sf -\dfrac{c}{2} + 43 = 50 [/tex]

Subtract 43 from both sides:

[tex] \sf -\dfrac{c}{2} + 43 - 43 = 50 - 43 \ \sf -\dfrac{c}{2} = 7 [/tex]

Multiply both sides by -2:

[tex] \sf -\dfrac{c}{2} \times (-2) = 7 \times (-2) \ \ \implies \boxed{\sf c = -14} [/tex]

Step-by-step explanation:

1. Data: is referred to as the collection of facts such as values and measurement. It include but isn't limited to attributes, names, fields and definitions that are being used in a computer database system.

2. Quantitative: this nature of data can be classified as discrete or continuous data. It is typically based on numerical values such as mathematical or statistical analysis of data gathered or collected from various sources e.g questionnaires, polls, surveys etc.

3. Sample: it is a sub-collection of elements coming from a certain population. Sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.

4. Black, blue, yellow, and red are examples of what qualitative data according to its nature. It includes variables that are non-numerical in nature i.e they are categorical. For example, the color of a car, gender, shapes etc.

5. Juan conducted his research using a survey method because he created a questionnaire so as to gather data from his participants.

Answer: y = -x-8

Step-by-step explanation:

(-3,-5) (-5,-3)

Slope (m) = (y-y)/(x-x) = (-3- -5)/(-5- -3) = (-3+5)/(-5+3) = 2/- 2 = - 1

m = - 1

Point (-3,-5)

y-y=m(x-x)

y- -5= -1(x- -3) = y+5 = -1(x+3)

y+5 = - x -3

y+5= - x - 3 (substract 5 from both sides)

y = - x - 8

Answer:

20%

Step-by-step explanation:

40-32=8

8/40=20%

This is what I think I hope it helps If right mark me brainliest If wrong tell me and I will figure out another answer.

Answer:

32 are eaten so we need to eliminate that from the total pieces.

40 - 32 = 8 are not eaten YET

8/40 since there are 8 out of 40(in total) that are not eaten

Now we need to convert 8/40 into a percent which means we multiply by a 100 to get 20%.

Answer:

405 cycles

Step-by-step explanation:

We have the equation:

y = 6*sin(324*π*t)

For the properties of the sin function, we know that the period is 2π.

So between:

Sin(x) and Sin(x + 2*pi)

we have a cycle.

between:

Sin(x) and Sin(x + 6*pi)

we have 3 cycles.

and so on.

Now we want to find how many cycles will occur between t = 3 s, and t = 5.5 seconds

Between these times, the difference in the argument of the sin function is:

324*π*5.5 - 324*π*3 = 324*π*(5.5 - 3) = 324*π*2.5

Now, the number of cycles that we will have between these times is equal to the number of times that "2*π" is in 324*π*2.5

That number is just the quotient between 324*π*2.5 and 2*π

N = (324*π*2.5)/(2*π) = (324*2.5)/(2) = 405

There are 405 cycles between 3 seconds and 5.5 seconds.

Answer:

EFG = 104°

GFH = 76°

Step-by-step explanation:

The sum of a linear pair is always equal to 180°

So lets solve for the variable n

2n + 32 + 4n + 16 = 180

6n + 48 = 180

6n = 132

n = 22

So now we know N

EFG = 4n + 16

EFG = 88 + 16

EFG = 104°

GFH = 2n + 32°

GFH = 44 + 32

GFH = 76°

Answer:

Yes, they are equal

Step-by-step explanation:

To see if a ratio is equal, multiply the first numbers of each ratio to the second numbers. If they equal the same, they are equivalent.

In this case, 10*4 = 40

20*2 = 40
