Write an explicit formula for An​, the nth term of the sequence 4, -20, 100, ...

Step-by-step explanation:

first off: write the formula that you would be using, which in my case would be

A = B x H

the B stands for base, and the H stands for height

the base of the shape would be 14.3 in

while the height is the dotted line in the middle (which would be 14.4 in)

to find the answer you would write it like this:

A = B x H = 14.3in x 14.4in

= (conversion to other form of measurement if necessary)

= 205.92 in

(answer may be wrong as it was calculated with calculator app)

Step-by-step explanation:

Answer:

When an exponent is 1, the base remains the same. a 1 = a . When an exponent is 0, the result of the exponentiation of any base will always be 1, although some debate surrounds 0 0 being 1 or undefined. For many applications, defining 0 0 as 1 is convenient.. a 0 = 1 . Shown below is an example of an argument for a 0 =1 using one of the previously mentioned exponent laws.

\(\huge\boxed{-\frac{3}{25} }\)

Step-by-step explanation:

-0.12 in fraction form can be written as:

=> - 12/100

=> - 6 / 50

=> - 3/25

Answer:

\(\large \boxed{\mathrm{A. \ -3/25}}\)

Step-by-step explanation:

Convert the decimal to a fraction.

-(0.12) = -(12/100)

Simplify the fraction.

-(12/100) = -(6/50) = -(3/25)

Answer:

profit = revenue - expenses

expenses : 125,000 + 6.50x

revenue : 9x

so to make a profit, ur revenue (income) has to be higher then ur expenses

revenue > expenses

A. ) 9x > 125,000 + 6.50x

9x - 6.50x > 125,000

2.5x > 125,000

x > 125,000 / 2.5

x > 50,000......so they would have to sell at least 50,001 devices to make a profit <==

B.) the cost of making 1 device is 10% more then the company predicted....10% more then 6.50.....6.50(1.10) = 7.15.....this is the new cost of making 1 device <==

9x > 125,000 + 7.15x ....this is the inequality with the 10% more added

9x - 7.15x > 125,000

1.85x > 125,000

x > 125,000 / 1.85

x > 67,567.5......so to make a profit, they would have to sell at least 67,568 devices to make a profit <==

Answer:

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Step-by-step explanation:

The given equation is:

4 = u + at

where u = 17, a = 4, and t = 8.

Substituting the given values, we get:

4 = 17 + 4(8)

Simplifying the right-hand side:

4 = 17 + 32

Combining like terms:

4 = 49

This is not a valid equation, as the left-hand side is not equal to the right-hand side.

Therefore, there may be an error in the given equation or values. Please check and provide the correct equation or values, so that we can help you find the value of v.

Answer:

a shaded region below a dashed boundary line

Step-by-step explanation:

this inequality uses the "less than" symbol (<), so we will use a dashed line because we are not including the values on the line

plug in (0,0) to see if we are shading above or below the line

0 < -1/2(0) + 5

0 < 5

this is true, so we will shade in the side that the point (0,0) is located, which is below the line (we know this because the inequality has a y intercept of 5)

Answer:

The rate of change in elevation for the second scuba diver is -82 feet per minute.

Step-by-step explanation:

-123 feet every minute.

1.5x more than 2nd diver.

-123/1.5 = 2nd diver rate

2nd diver rate = -82

The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Given that, a scuba diver's elevation changed by -123 feet every minute.

When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half  hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.

1½=1.5 times the rate of change for a second scuba diver

Now, rate of change in elevation of the second scuba diver

= -123/1.5

= -82 feet per second

Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Answer:

The lines coincide

The slopes are equal

The y-intercepts are equal

The system has an infinite amount of solutions

Step-by-step explanation:

If you convert both equations into slope-intercept form, you will be able to see that both are y = 5/2x -3. When both lines are the same, it means that they are the same line and they have an infinite amount of solution. If they are the same line, it also means their slopes and y-intercepts are same as well. Thus, you have your derived answer.

Step-by-step explanation:

Answer:

This represents a proportional relationship, the ratios are equivalent, and the constant of proportionality is 7.7.

Step-by-step explanation:

Since we know that six cell phones weigh 46.2 oz, we can divide 46.2 by 6 to find the weight of each, so 46.2/6=7.7.

We also know that fourteen cell phones weigh 107.8 oz, so we divide 107.8 by fourteen and get 7.7 as well.

Since both ratios equal 7.7 oz per cell phone, the ratios are equal and the relationship is proportional.

ANSWER: m > -4

Step-by-step explanation:

To design a spinner with the given probabilities, we can use the following sectors:

A sector covering 60 degrees for the number 1, with probability 1/6.

A sector covering 120 degrees for the number 3, with probability 1/3.

A sector covering 180 degrees for the number 7, with probability 1/2.

A sector covering 180 degrees for the odd numbers (1 and 3), with probability 1.

To create the spinner, draw a circle and divide it into four equal sectors. Color one sector red for the number 1, color two adjacent sectors green for the number 3, color one remaining sector blue for the number 7. Finally, color half of the blue sector green to represent the odd numbers.

The resulting spinner will have the desired probabilities: P(1) = 1/6, P(3) = 1/3, P(7) = 1/2, P(odd number) = 1.

Answer:

Step-by-step explanation:

4 parts: 1/3 + 1/2 + 30min + 60min

1/3 of an hour is = 20 minutes

1/2 of an hour is 30 minutes

20 + 30 + 30 + 60(1h)= 140 minutes = 2 hours and 20 minutes

The total time did the program take to write is  2 hours and 20 minutes.

It is required to find total time.

The branch of mathematics dealing with the properties and manipulation of numbers. a science that deals with the addition, subtraction, multiplication, and division of numbers. Fractions, decimals, percentages, fractions, square root, exponents, and other arithmetic operations are used to achieve mathematical simplifications.

Given that:

several people working on each of 4 parts.

First part = 1/3 of the total time,

The second part = 1/2 of the remaining time,

The third part =30 minutes,

Fourth part= 60 minutes,

So, the total time in hour.

4 parts:

1/3 of an hour is = 20 minutes

1/2 of an hour is 30 minutes

Total time=1/3 + 1/2 + 30min + 60min

=20 + 30 + 30 + 60(1h)

= 140 minutes

= 2 hours and 20 minutes.

So, the total time did the program take to write is  2 hours and 20 minutes.

Answer:

Hey There!

Let's solve....

Isolate for x first which is

\(x = \frac{3 + 3y}{4} \\ \)

\(substitute \: x = \frac{3 + 3y}{4} \\ \\ \brack \: 5 \times \frac{3 + 3y}{4} - 4y = 3 \\ \\ \)

Now simplify...

\( \brack \: \frac{15 - y}{4} = 3 \\ \\ = y = \frac{15 - 3}{4} \\ \\ = \frac{12}{4} \\ simplify \\ \\ \frac{ \cancel{12} ^{3} }{ \cancel{4}^{1} } \\ x = 3\)

Y=3

x = -1.3

I hope this is right, and I am sorry if this is wrong if it is! I rlly hope this helps you out and you can understand my method and the way I typed this!!

Step-by-step explanation:

We are going to use one of my fav methods! The substitution method!

Set this aside for now: 4x - 3y = 3     We gonna use this one: 5x - 4y = 3

5x - 4y = 3

= 5x - 3 = 4y

( also, the subtraction is with the 4y as a negative, so 4y would be positive if you moved it!)

Divide all of the equation by 4!

y = \(y = \frac{5x - 3}{4}\)

Now, you take take the other equation and substitute the y with what you have above!

\(4x - 3 times \frac{5x - 3}{4} = 3\)

you cross multiply 4( the denominator) with the other side that has only a three!

4x - 3 \(times 5x - 3\) = 12

4x - 15x - 3 = 12

-11x - 3= 12

Move the three to the other side become positive!

-11x = 15

divide both sides by -11

x = -1.3
