-4, -1/2, 3, 13/2, 10,… represents an arithmetic sequence.

An arithmetic sequence progresses with a common difference which is the difference of consecutive terms.

So for each of the number sequences, we will try to check if the consecutive terms has a common difference.

A) 32, 16, 8, 4, 2,...

16-32 = -16

8-16 = -8

4-8 = -4

2-4 = -2

As the differences of consecutive terms are not same, this sequence is not an arithmetic sequence.

B)5, 10, 20, 40, 80,...

10-5 = 5

20-10 = 10

40-20 = 20

80-40 = 40

Here also the differences of consecutive terms are not same, this sequence is not an arithmetic sequence.

C) -4, -1/2, 3, 13/2, 10,…

-1/2- -4 = 7/2

3- -1/2 = 7/2

13/2-3 = 7/2

10-13/2 = 7/2

This sequence has a common difference and hence is an arithmetic sequence.

D) 4, 8/3, 16/9, 32/27, 64/81,…

8/3-4 = -4/3

16/9-8/3 = -8/9

32/27-16/9 = -16/27

64/81-32/27 = -32/81

Here also the differences of consecutive terms are not same, this sequence is not an arithmetic sequence.

The sum of two hundred even numbers in the sequence from 0 to 398 is 39800

To find the sum of two hundred even numbers from 0 to 398, we can use the formula of sum of an arithmetic progression.

[tex]S_n = \frac{n}{2}[2a(n-1)]d[/tex]

The number of terms given here is 200, the first term is 0 and the common difference is 2

Substituting the values into the equation

[tex]S_n = \frac{n}{2}[2a+(n-1)]d\\S_n = \frac{200}{2}[2*0+(200-1)*2\\S_n = 100(0+199)*2\\S_n = 39800[/tex]

V'(t) = -250(1-(1/40)t)

If we know the time, we can plug in the value for "t" in the above derivative and find how much water drained for the given point of t.

Given:

V =2000( 1- (1/40)t)^2   , where 0≤t≤40.

Here we have to find the derivative with respect to "t"

We have to use the chain rule to find the derivative.

V'(t) = 2 (2000)(1- (1/40)t)d/dt(1- (1/40)t)

V'(t) = 2(2000)(1-(1/40)t(-1/40)

When we simplify the above, we get

V'(t) = -250(1-(1/40)t)

If we know the time, we can plug in the value for "t" and find how much water drained for the given point of t.

Answer:660 in

Step-by-step explanation: Just add 6 sides, 9 ft= 108 in, + 2 in = 110, 110x6 = 660

The actual height of the building is 739.2 feet.

Given the height of a building estimated by Charlie is 924 feet.

His father said that there is 20% error in the estimation.

we should determine 20% of the estimated height.

⇒ height = 924 feet

⇒ error = 20%

⇒ 924 × 20/100

⇒ 924/5

= 184.8 feet

Subtract the error in height with the height given.

⇒ estimated height - error in height

⇒ 924 - 184.8

= 739.2 feet.

hence the actual height is 739.2 feet.

Answer: -27

Step-by-step explanation: -3 raised to the power of 3 is written (-3) 3 = -27. Note that in this case the answer is the same for both -3 3 and (-3) 3 however they are still calculated differently. -3 3 = -1 * 3 * 3 * 3 = (-3) 3 = -3 * -3 * -3 = -27. For 0 raised to the 0 power the answer is 1 however this is considered a definition and not an actual calculation.

The graph of the first linear equation:

y = x + 3

Can be seen in the image at the end.

Let's graph the first line, which is:

y = x + 3.

To graph it, we need to find two points on the line, to find these, we can evaluate the linear equation in two values of x.

Using x = 0 we get:

y = 0 + 3

y = 3

So we have the point (0, 3).

Using x = 1, we get:

y = 1 + 3

y = 4

So we have the point (1, 4)

Now we can graph these two points on the same coordinate axis and connect them with a line. Like in the example below.

The probability that a randomly selected student in the class test scored marks which is less than 82 is 0.9192

It is given that in a test, the scores for an exam normally distributed has a mean of 75 and a standard deviation of 5. We have been asked to find the probability that a randomly selected student scored less than 82.

From the question we have,

Mean = 75

Standard deviation (SD)  = 5

Therefore, the probability that a randomly chosen student has a score of less than 82 is represented as:

(P) Probability ( X < 82) = P { Z < [tex]\frac{82-75}{5}[/tex] }

                = P {Z < 7/5}

                = P {Z <1.4}

                = Area from - ∞ to  1.4

                = 0.9192

From the z table the area under the normal curve that corresponds to  1.4 is  0.9192

Hence the required probability of that a randomly selected student scored less than 82 is 0.9192

Answer:

f(-2) = -8

Step-by-step explanation:

We are given a function:

[tex]f(x)=2x-4[/tex]

We are told to find f(-2).

First, substitute -2 as x in f(x):

[tex]f(x) = 2x-4\\\\f(-2) = 2x-4[/tex]

Then, substitute -2 as x in the equation itself:

[tex]f(-2) = 2(-2) - 4[/tex]

Then, simplify by multiplying 2(-2):

[tex]f(-2) = 2(-2) - 4\\\\f(-2) = -4 - 4[/tex]

Finally, simplify by performing the final arithmetic:

[tex]f(-2) = -4 - 4\\\\f(-2) = -8[/tex]

Therefore, f(-2) = -8.

Step-by-step explanation:

A line with a perpendicular slope with have a slope that is the negative inverse of the reference line.  If the reference line is -(2/3), the perpendicular line will have a slope of (3/2).

The line formed by ab:  y = (3/2)x + b

We have one given point on line ab with one coordinate known, (3,4), so let's use it to find b:

y = (3/2)x + b

4 = (3/2)*3 + b for (3,4)

4 = (9/2) + b

b = 4 - (9/2)

b = - 0.5

The equation is y = (3/2)x - 0.5

The slope of (3/2) is equal to the Rise/Run of two points on the line:  (3,4) and (w,-5):

    Rise = (4 - (-5)) = 9

    Run = (3 - w)

Slope =  9/(3-w)

(3/2) =  9/(3-w)

(3/2)(3-w) =  9

(9/2) - (3/2)w = 9

9 - 3w = 18

-3w = 9

w = -3

Point b is (-3, -5)
