The 9th term of the geometric sequence 6, 24, 96, ... is 393216

What is Sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.

The given sequence  6, 24, 96, ...

six, twenty four, ninety six

a is first term=6

r is common ratio = 24/6=4

The nth term of Geometric sequence aₙ=a.rⁿ⁻¹

9th term a₉=6(4)⁸

=6(65536)

=393216

Hence, the 9th term of the geometric sequence 6, 24, 96, ... is 393216

What is a quadrant?

A quadrant can be defined as a region or part of a cartesian plane that is obtained when the two axes x and y intersect each other at 90°. There are four regions formed.

They are called quadrants. each is denoted by  Roman numerals and named as Quadrant I, Quadrant II, Quadrant III, or Quadrant IV based on their position with respect to the axes.

All angles Sin, cos, and tan are positive on the first quadrant. This is because they fall on the positive and y axes respectively.

Given sinθ = 4/7 and cosθ is positive. because the sine and cosine are both positive, it is right to conclude that the angle is in the first quadrant. (Option D).

Each of the four portions of the coordinate plane is represented by a quadrant. And when we talk about sections, we mean sections as defined by the coordinate axes.

So the x-axis is right here, and the y-axis is up and down. It divides a coordinate plane into four pieces, as you can see.

Given  sinθ = 4/7 [Note that the Sine is positive in the first and second quadrants]

for Cos θ > 0  [The cosine is positive in the first and fourth quadrants]

⇒ θ ∈ (0, π/2)   [The Angle belongs to the first quadrant]

Hence, the angle is in the first quadrant because the sine and cosine are both positive.

Harry Hardworker's wage Range is $470.

The Harry Hard worker's wage range, we need to examine the given information and find the appropriate wage range that corresponds to the amount of money withheld, which is $10.00.each piece of information:

1. A person with 4 exemptions making between $380 and $400 would have $ withheld.

This information implies that the person's wage falls within the range of $380 to $400.

2. A person with 2 exemptions making between $620 and $640 would have $ withheld.

This information indicates that the person's wage falls within the range of $620 to $640.

3. A person with 1 exemption making $470 would have $ withheld.

This information tells us that the person's wage is exactly $470.

4. A person with 3 exemptions making between $560 and $580 would have $ withheld.

This information suggests that the person's wage falls within the range of $560 to $580.

From the given data, we can conclude that Harry Hardworker's wage is within one of these ranges. However, since we know that $10.00 was withheld from his paycheck, we need to find the corresponding wage range.

Looking at the information provided, we can see that the only wage range that includes $10.00 as the amount withheld is the range associated with a person having 1 exemption and making $470.

Therefore, Harry Hardworker's wage range is $470.

The inequality value that would be able to show/x/ ≤ 5 is option A

In mathematics, inequality refers to a mathematical statement that expresses a relationship between two quantities, indicating that one quantity is greater than, less than, or not equal to the other.

Answer:

x = 2/5, y= -22/5

Step-by-step explanation:

4x−y=6;3x−2y=10

Step: Solve4x−y=6for y:

4x−y+−4x=6+−4x(Add -4x to both sides)

−y=−4x+6

-y/-1 = -4x +6 over -1 (Divide both sides by -1)

y=4x−6

Step: Substitute4x−6for y in 3x−2y=10:

3x−2y=10

3x−2(4x−6)=10

−5x+12=10(Simplify both sides of the equation)

−5x+12+−12=10+−12(Add -12 to both sides)

−5x=−2

-5x/-5 = -2/5 (Divide both sides by -5)

x=  2 /5

Step: Substitute  2/ 5  for x in y=4x−6:

y=4x−6

y=4 ( 2/ 5 ) −6

y=  −22 /5

(Simplify both sides of the equation)

x = 2/5, y= -22/5

Step-by-step explanation:

The compound interest formula tells you the amount will be ...

  FV = P(1 +r/n)^(nt)

for principal P at annual rate r compounded n times per year for t years.

  FV = $4000(1 +.06/4)^(4·7) = $4000(1.015^28) ≈ $6068.89

The time Jack left Santa Clara is 1 : 55 pm

A word problem in math is a math question written as one sentence or more. These statements are interpreted into mathematical equation or expression.

The time for Jack to walk to lose Altos is 25 min and he uses another 25mins to work to Palo alto.

Therefore, the total time he spent is

25mins + 25 mins = 50 mins

He arrived Palo at 2 :45 pm, therefore the time he left Santa Clare will be ;

2:45 pm = 14 :45

The sample space for rolling a fair seven-sided die is the one on the first option.

S= {1, 2, 3, 4, 5, 6, 7}

For any experiments with some given outputs, the sample space is the set of the possible outputs.

For example, for a coin with two outputs (heads and tails) the sample space is just {head, tails}

Particularly, for a fair seven-sided die we have 7 possible outputs, which are all the whole numbers from 1 to 7, then the sample space for that die is:

S= {1, 2, 3, 4, 5, 6, 7}

Answer:

BRO, u dont need to be a god :D, This is simple math and you just need to use your brains

Step-by-step explanation:

Given is a polynomial, and the values of the variables in it are given by showing what set are they an element of, right? It just gets easier from here

They tell us that 'z' is an element of set C, which stands for Complex Numbers.

And they also tell us that 'a' is an element of set Z, which stands for Integers, which are just numbers with a sign :).

They have also given us a root (solution) to the polynomial, which is also a complex number.

The two statements given are just there for us to verify that we are on the right track to the solution.

We can see that (z = 3 + i) which of course is a complex number, due to the presence of 'i', and 'a' is an integer for when we find its value.

Put it all together and we will get the answer.

Like this,

take the given value of 'z' and place it into the polynomial given, now keep your eyes open here. They said the value of z is as such when the polynomial is an equation which equals 0, so hence we get this:

P(z) = a(3+i)³ - 37(3+i)² + 66(3+i) - 10 = 0,

now just go on simplifying,

=> a(3³+i³+3×3²i+3×3i²) - 37(3²+2×3×i+i²) + 66×3 + 66×i - 10 = 0

=> a(27-i+27i-9i) - 37(9+6i-1) + 198 + 66i - 10 = 0

=> a(27+17i) - 37(8+6i) + 188 + 66i = 0

=>  a(27+17i) = 296 + 222i - 188 - 66i

=> a(27+17i) = 108 + 156i

=> a = (108+156i) / (27+17i)

=> a = (108+156i)(27-17i) / (27)² - (17i)²

=> a = (5568 + 2376i) / (699 + 289)

=> a = 5568 + 2376i / 1488

The answer for blanks in statements are, an x-intercept of 1 , -3, x>1 , increasing , 7.5.

Many mathematical and real-world phenomena are described by functions. Modeling real-world occurrences like population increase, interest rates, or physical motion is frequently done using them. There are many distinct features that functions can have, including continuity, differentiability, and periodicity. Functions can also be linear or nonlinear.

The domain and range of functions are crucial components. The set of all potential input values makes up the domain of a function, whereas the set of all possible output values makes up the range. The behaviour of a function, such as whether it is increasing, decreasing, or constant, can also be used to categorize it. A function's graph shows the relationship between its input and output values graphically.

Function h has an x-intercept of 1 and a y-intercept of -3.  The function is positive for x>1 and increasing on all intervals of x. The average rate of change for the function on the interval [0, 2] is 7.5

Step-by-step explanation: We know that the apartment costs $1100 per month during the first year but if it goes up 110 dollars per year how much would total be in 11th year?

First we need to multiply 1100 and 110 which equals 121,000

Secondly, of course we need to make sure that our anwser is correct, now we divide 121,000 with 11 years (which equals 1100)
