Can I get some help on this problem? Thanks guys yo its really easy but I cant figure it out I need an explanation so dont post without one

h(6) = 8

reading vertically from x = 6 , we get , horizontally that y = 8

When you are given the side length and apothem of a regular polygon and asked for area, you are expected to use the formula

... A = (1/2)Pa

where P is the perimeter of the polygon, "a" is the apothem, and A is the area.

The only additional information you need is that a decagon has 10 sides, so its perimeter is 10×3.2 inches = 32 inches.

The area is ...

... A = (1/2)(32 in)(5 in)

... A = 80 in²

_____

Sometimes the dimensions of a problem like this don't quite add up. The geometry of a regular polygon means that the apothem can be found from the side length and vice versa. In this case, the side length of 3.2 inches means the apothem is about 4.92 inches; or the apothem of 5 inches means the side length is about 3.25 inches. Either way, the area is slightly different from that computed using the given numbers.

This is why I say you're expected to use the above formula. (You're not expected to think about it too much.)

Answer:

I'd say you need to be more specific.

Step-by-step explanation:

"Different" doesn't tell you much.

Consider the equations ...

These equations are "different", but they are dependent.

_____

I'd mentally (or actually) put the equations in the same form and compare the coefficients of x and y. If they have different ratios, the system is independent and consistent.

If they have the same ratio, the system will not have a single solution. Whether there is no solution or an infinite number of solutions depends on the constant, which I would examine next.

The system above can be put in the form

In both cases, the ratio of the x coefficient to the y coefficient is 2/-1 = 4/-2 = -2. This means the lines are at least parallel, if not identical. The numbers in the second equation are all 2 times the numbers in the first equation, so the equations are dependent, and there are an infinite number of solutions. (Both describe the same line.)

If the second equation were 4x -2y = 1, then the two equations would be describing parallel lines, so they would be called inconsistent.

I believe that the answer is C, I don't know if it is addition or multiplication, but if is is addition, it would be 146, C

Answer: about 0.0432 or 4.32%

Step-by-step explanation:

Given : A bag of marbles contains 7 red, 5 blue, 4 green, and 2 yellow marbles.

Total marbles = 7+5+4+2=18

Let R : Event of getting first marble as red .

Y= Event of getting second marble as yellow.

Jon selects a marble, replaces it, then selects another marble.

⇒Both events are independent .

Probability of getting first marble as red = [tex]P(R)=\dfrac{\text{Number of red marbles}}{\text{Total marbles}}[/tex]

[tex]\\\\=\dfrac{7}{18}[/tex]

Probability of getting second marble as yellow = [tex]P(Y)=\dfrac{\text{Number of yellow marbles}}{\text{Total marbles}}[/tex]

[tex]\\\\=\dfrac{2}{18}[/tex]

Now, the probability that Jon selects a red marble and then a yellow marble :

[tex]P(R)\times P(Y)=\dfrac{7}{18}\times\dfrac{2}{18}\approx0.0432=4.32\%[/tex]  [ ∵ Event R and Y are independent .]

Hence, the probability that Jon selects a red marble and then a yellow marble is about 0.0432 or 4.32%.

The answer is 1 / (5^3)

See the attached picture:

Total of fees: 1,000 + 4,900 = 5,900

You are told the APR is the total fees divided by the amount financed, so divide the total fees by the amount financed:

5,900 / 83,098.59 = 0.71

0.71 x 100 = 7.1% APR.

The answer is B.

Answer:

3.6 miles

Step-by-step explanation:

For a trip of x miles, there are x-0.5 miles of it that are "additional", which makes (x-0.5)/0.1 additional tenths.

Then the charges (in dollars) are ...

... 3.50 + 0.30(x -0.5)/0.1

Adding a tip of $2 and requiring the total be less than $15 gives ...

... 3.50 + 0.30(x -0.5) + 2.00 ≤ 15.00

... 5.50 + 3(x - 0.5) ≤ 15.00 . . . . simplify a bit

... 4.00 +3x ≤ 15.00 . . . . . . . . . . simplify more

... 3x ≤ 11.00 . . . . . . subtract 4.00

... x ≤ 3.667 . . . . . . divide by 3

Miles are measured in tenths. We cannot go 3.7 miles on $15, but we can go 3.6 miles.

x = 10

[tex]\frac{x-2}{4}[/tex] = 2 ( multiply both sides by 4 to eliminate fraction )

x - 2 = 4 × 2 = 8 ( add 2 to both sides )

x - 2 + 2 = 8 + 2

x = 10

2x + 16 = 5

2x = -11

x = -5.5

y = 5

(-5.5,5)

Final answer:

The solution to the system of equations y=5 and y=2x+16 is found using substitution, yielding the solution (-5.5, 5).

Explanation:

To solve the system of equations y=5 and y=2x+16, we can use the method of substitution. Since the first equation directly gives us the value of y, we can substitute y = 5 into the second equation to find the corresponding value of x. Doing so, we have 5 = 2x + 16. To solve for x, we subtract 16 from both sides to get -11 = 2x, and then divide both sides by 2 to find that x = -5.5. Thus, the solution to the system is (-5.5, 5).

This would just be 7 1/5 + 3/5 since the negative sign gets distributed and makes (-3/5) into a positive number.

From there you have basic math and you get 7 4/5.

The subtraction of the given expression will be [tex]7\dfrac{4}{5}[/tex].

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The subtraction will be calculated as:-

[tex]=7\dfrac{1}{5}-(-\dfrac{3}{5})[/tex]

[tex]= \dfrac{36}{5}+\dfrac{3}{5}\\\\\\= \dfrac{39}{5}\\\\\\= 7\dfrac{4}{5}[/tex]

Therefore subtraction of the given expression will be [tex]7\dfrac{4}{5}[/tex].

Final answer:

To evaluate (f ∘ g)(4), we substitute the value of g(4) into f(x) which gives us 22.

Explanation:

To find (f ∘ g)(4), we need to first evaluate g(4) and then plug that value into f(x). Given that g(4) = 8 and f(8) = 22, we can substitute 8 into f(x) as follows:

(f ∘ g)(4) = f(g(4))

(f ∘ g)(4) = f(8)

(f ∘ g)(4) = 22

Answer:

a = 4.762203156

Step-by-step explanation:

Given:

ab^4 = 12 and a^5b^5 = 7776

Making the equations a subject of a;

a = 12/b^4 and a^5 = 7776/b^5

Finding fifth root on both sides of equation two;

a = [tex]\sqrt[5]{7776}[/tex]/b

You will get a = 6/b

Equating the two equations;

12/b^4 = 6/b

Multiplying both sides by b^4 gives:

b = [tex]\sqrt[3]{2}[/tex] = 1.25992105

We had that a = 12/b^4 so;

a = 12/1.25992105^4 = 12/2.5198421 = 4.762203156

Try this option (this is not the only way!):

1. the rule: if 'number_1' - 'number_2' > 0, then number_1>number_2. If 'number_1'-'number_2'<0, then number_2>number_1.

2. according to the rule above: 9.36-9.359=0.001. 0.001>0, it means, 9.36>9.359.

Answer:

b = 24

d = 10

f = 32

g = 34

h = 46

Step-by-step explanation:

From the given table we find that students who are in band = 48

So 24 + b = 48

b = 48 - 24

b = 24

Total students who do not play sports = h

And h = students in band + students not in band

h = b + 22

h = 24 + 22 = 46

h = 46

Total students who play sports and who do not play sports = 80

g + h = 80

g + 46 = 80

g = 80 - 46 = 34

g = 34

Total students who are not in band and not in band = 80

48 + f = 80

f = 80 - 48

f = 32

Students who are not in Band but either play sports or do not play sports = f

d + 22 = f

d + 22 = 32

d = 32 - 22 = 10

d = 10

Using the change of subject, the values of the alphabet b, d, f g, h calculated from the table are 24, 10, 32, 34, and 46 respectively.

To find b :

24 + b = total

24 + b = 48

b = 48 - 24

b = 24

To find h :

b + 22 = total

b + 22 = h

24 + 22 = 46

h = 46

To find g :

g + h = 80

g + 46 = 80

g = 80 - 46

g = 34

To find d :

24 + d = g

24 + d = 34

d = 34 - 24

d = 10

To find f :

d + 22 = f

10 + 22 = f

f = 32

Therefore, the values of b, d, f g, h are 24, 10, 32, 34, and 46 respectively.

A(6) = 2500 × [tex]e^{(0.05(6))}[/tex] = 2500 × [tex]e^{0.3}[/tex] = $3, 374.65

My investment amount will be 3374.65 rupees after 6 years.

So, option B is the correct answer.

What is Euler's number ?

A(t) [tex] = p {e}^{rt} [/tex] is known as Euler's number.

A is the desired amount per account/price/population/etc. equal

P is the principal or amount you start with.

e is a particular irrational number that is approximately 2.718. Just as pi is a concrete irrational number, so is e. The Euler number is often used as a title for e. Just as pi is an infinite non-repeating decimal, so is e. And just as many people use 3.14 to approximate pi, some use 2.718 for e. However, using the special π button on the calculator gives a more accurate answer than 3.14, and using the e button on the calculator is more accurate than using 2.718.

r is a rate written as a decimal, not a percentage.

t is time.

Let's say you have a population of bacteria that is constantly growing at a rate of 15% per hour. If there were 40 bacteria at the beginning of the experiment, how many bacteria will there be after 8 hours?

A is the amount after 8 hours, it's unknown, so I'll just use the variable A.

P initially has 40 bacteria.

e I use the “e” button on my calculator.

r is the hourly rate of 15%, I write it as 0.15

t is time, in this case 8 hours.

A = 40•e^(0.15•8)

A = 132.8, you need to round down because you haven't reached the next whole number of bacteria.

132 bacteria after 8 hours.

Here given,invest amount is $2,500 and rate of interest is 5% and total time period is 6 years.

Here we need to use continuous function A(t)[tex] = p {e}^{rt} [/tex]

Where P is principal,r rate of interest is interest and t is time.

Now,

[tex]p = 2500 \\ r = 5\% = 0.05\\ t = 6 \: years[/tex]

So,after 6 years the amount become ,A(6)

= [tex]2500 \times {e}^{0.05 \times 6} \\ = 2500 \times {e}^{0.3} [/tex]

[tex] = 2500 \times 1.34986 \\ = 3374.65[/tex]

Therefore,my investment amount will be 3374.65 rupees after 6 years.

Answer:

216

Step-by-step explanation:

9 * 6 = 54

54 * 8 = 432

432/2 = 216 is the answer

The volume of a triangular prism is the area of the base multiplied by the height. This can be represented as volume = base × height

Let's first identify our values:

9 m = height of the prism

6 m = base of the triangle

8 m = height of the triangle

First, we need to calculate the area of the triangle. To calculate the area of a triangle, the formula is base × height ÷ 2.

The base of the triangle is 6 and the height of the triangle is 8 so 6 multiplied by 8 will give us a product of 48. Next, we need to divide 48 by 2 and we will get a quotient of 24.

Finally, we need to multiply the area of the triangle by the height of the prism.

24 × 9 = 216

Therefore, the volume of the triangular prism is 216[tex]m^{3}[/tex]

substitute y = 3 into the other equation

3 = 2x + 3 ( subtract 3 from both sides )

0 = 2x → x = 0

solution : (x, y) → (0, 3 )

(2)

substitute y = x into the other equation

x = 2x - 5 ( subtract x and add 5 to both sides )

Step-by-step explanation:

See this solution/explanation (answer is '7 meters'):

1. According to the condition 'y' means the height, and 'x' - the length from the start of the lift hill.

2. The phrase 'height of 343 meters' means y=343.

3. From the another side y=x³. If to substitute 343 instead of 'y': 343=x³, - it is possible to find the value of 'x'.

x=7 [m] - how far from the start of the lift hill...

x = 15

since the figures are similar then the ratios of corresponding sides are equal

[tex]\frac{x}{6}[/tex] = [tex]\frac{20}{8}[/tex] ( cross- multiply )
