The distance around the window is 92.52 inches.

A semicircle is a one-dimensional locus of points that forms half of a circle. It is a circular arc that measures 180°. It has only one line of symmetry.

Given that, The stained-glass window is semicircular and the bottom edge of the window is 36 in.

We get that, diameter of the window = 36 in

radius = 18 in

Circumference of semicircle = r(2+π)

= 18(2+3.14)

= 92.52 in

Hence, The distance around the window is 92.52 inches.

Answer:

The range of areas is 3.14ft^2- 12.56ft^2

Step-by-step explanation:

I don't know which graph the question is referencing but I found the range of areas this way

first I found out what the range of radius would be

since the circumference is pi*diameter

So to find the diameter I did the individual areas divided by pi

6.28/3.14=2

12.56/3.14=4

So the range of diameters is 2 to 4 this means the range of radius's are 1 to 2

Since area of a circle is r^2*pi

This means the range of areas is

1^2*3.14=3.14

2^2*3.14=12.56

So the range of areas is 3.14ft^2 to 12.56ft^2

Answer:

43.96 inches

Step-by-step explanation:

when you have the diameter of a circle, you just multiply it by pi and you will get the answer. since your diameter is 14, you multiply it by 3.14 and you will get 43.96 inches

Using π as 3.14, the circumference of the circle with a diameter of 14 inches is approximately 43.96 inches. This level of precision is suitable for most practical applications.

To find the circumference (C) of a circle, you can use the formula C = πd, where d is the diameter. In this case, the diameter is given as 14 inches.

Given the options of using either 22/7 or 3.14 for π, let's use 3.14 for this calculation.

C = 3.14 × 14

≈ 43.96 inches

Therefore, the circumference of the circle is approximately 43.96 inches when using π as 3.14. This means that if you were to wrap a string around the edge of the circle, it would take nearly 43.96 inches of string to complete one full loop.

It's important to note that using 22/7 for π is another approximation and yields a slightly different result, but for most practical purposes, 3.14 is accurate enough.

16th term: -516560652

Step-by-step explanation:

Let's use the formula for a geometric sequence:

[tex]a_n=a_1r^{n-1}[/tex], where [tex]a_n[/tex] is the nth term, [tex]a_1[/tex] is the first term, and r is the common ratio

Here, we know the first term is 4. To find r, let's plug in 8 for n and -8748 for [tex]a_n[/tex]:

[tex]a_n=a_1r^{n-1}[/tex]

-8748 = 4 * [tex]r^{8-1}[/tex]

-8748 = 4 * [tex]r^7[/tex]

[tex]r^7[/tex] = -2187

r = -3

So we know that the common ratio is -3. Now, we want to find the 16th term, so n = 16:

[tex]a_n=a_1r^{n-1}[/tex]

Answer:

[tex]-3m^{12}{n^{6} }[/tex]

Step-by-step explanation:

To begin simplifying this, we can first divide the coefficients, giving us:

[tex]\frac{-3m^{5}n^{4} }{m^{-7} n^{-2} }[/tex]

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

[tex]\frac{-3m^{5+7} n^{4+2} }{1}[/tex]

Now, simplifying this gets:

[tex]-3m^{12}{n^{6} }[/tex]

Answer: 120 km/h

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate Hunk's time spent on his travel.

Speed rate = distance /time

Time = distance /speed = 540/ 90 =6 hours

Now, since Tim completed the same amount of distance with 1 hour and 30 min less (1.5) we have to subtract 1.5 hours to Hunk's time to calculate Tim’s time:

6-1.5 = 4.5 hours

Tim's speed rate = distance /time

s = 540/4.5 = 120 km/h

Final answer:

The rate of change is 1 and the initial value is 1.

Explanation:

The table shows the points (2, 3), (4, 5), (6, 7), and (8, 9). To find the rate of change, we can calculate the difference in y-coordinates and divide by the difference in x-coordinates for any two points. Let's take the points (2, 3) and (4, 5) as an example:

The difference in y-coordinates is 5 - 3 = 2.

The difference in x-coordinates is 4 - 2 = 2.

The rate of change is 2 / 2 = 1.

To find the initial value, we can look for the y-coordinate when x is 0 or when the equation is of the form y = mx + b. In this case, the initial value is 1.

The rate at which the water level fell is 1.05 mm/year. To find the total variation in water level, multiply this rate by 2.48 years, giving a total variation of 2.604 mm.

In Mr. Whittaker's science class, Matea recorded that the water level in one part of the river fell by 1.05 millimeters per year. This number - 1.05 millimeters - represents the rate at which the water level fell each year. To find the total variation in water level over the 2.48 years, you would multiply the rate (1.05 mm/year) by the time (2.48 years). So, the solution would be: 1.05 mm/year * 2.48 years = 2.604 mm. This results in a total variation of 2.604 millimeters over the 2.48 years. This total variation can now be compared to the average annual trend which is a rise of 1.8 mm/year.

ANSWER: A

Step-by-step explanation:

The solutions of the quadratic equation 3x² + 9x + 17 = 0 are x₁ = (-9 + √(123)i) / 6 and x₂ = (-9 - √(123)i) / 6, where "i" represents the imaginary unit.

To find the solutions of the quadratic equation 3x² + 9x + 17 = 0, we'll use the quadratic formula:

x = (-b ± √(b² - 4ac)) / 2a.

Here, a = 3, b = 9, and c = 17. We'll plug these values into the formula and simplify the expression step-by-step.

Step 1: Calculate the discriminant (Δ) using the formula Δ = b² - 4ac.

Δ = (9)² - 4 * 3 * 17

Δ = 81 - 204

Δ = -123

Step 2: Substitute the values of a, b, and Δ into the quadratic formula.

x = (-9 ± √(-123)) / 2 * 3

Step 3: Since the discriminant (Δ) is negative, the quadratic equation has no real solutions. Instead, it has two complex solutions.

Step 4: Simplify the expression under the square root.

x = (-9 ± √(-123)) / 6

Step 5: Now, we deal with the square root of a negative number, which is denoted by "i" in the complex number system. √(-123) = √(123)i.

Step 6: Substitute the value of √(-123) back into the equation.

x = (-9 ± √(123)i) / 6

Step 7: Divide both the real and imaginary parts by 6 to get the two complex solutions.

x₁ = (-9 + √(123)i) / 6

x₂ = (-9 - √(123)i) / 6

Final answer:

The quadratic equation 3x^2 + 9x + 17 = 0 has no real solutions because the discriminant is negative. The solutions are complex numbers and can be expressed as x = -3/2 ± √(123)/6 × i.

Explanation:

To find the solutions of the quadratic equation 3x^2 + 9x + 17 = 0, we will use the quadratic formula, which is x = (-b ± √(b^2 - 4ac)) / (2a) for a quadratic equation of the form ax^2 + bx + c = 0. In our case, a = 3, b = 9, and c = 17. Plugging these values into the formula gives:

x = (-(9) ± √((9)^2 - 4(3)(17))) / (2(3))

x = (-9 ± √(81 - 204)) / 6

x = (-9 ± √(-123)) / 6

Since the discriminant (the part under the square root, b^2 - 4ac) is negative, the equation has no real solutions. Instead, the solutions are complex numbers:

x = (-9 ± √(-123)i) / 6

The final solutions can be expressed as:

x = -3/2 ± √(123)/6 × i

Step-by-step explanation:

Key to this question is assume that each exchange preserves the total dollar amount of Nick’s money.

If He exchanges all his $5 bills for $1 bills, it means that a $5 bill will result in 5 $1 bills as such, if he had x number of $5 bill, after the exchange, he would have 5x $1 bills.

then all his $20 bills for $5 bills, it means that for each $20 bill, he gets 4 $5 bills which means that if he had y number of $5 bills, after the exchange, he would have 4y $5 bills.

and finally all his $100 bills for $20 bills, then he must have received 5 $20 bills for each $100 such that if he had z number of $100 bills before the exchange, he would have 5z number of $20 bills after the exchange. Given that originally he had 17 bills and later 77 bills then

x + y + z  = 17

5x + 4y + 5z = 77

Multiplying the first equation by 5,

5x + 5y + 5z = 85

5x + 4y + 5z = 77

subtract 2 from 1

y = 8

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

Like terms are those terms that are having the same variables, also the variables are of the same order as well. The value of the x can be written as (4 + 2z)/(7 + y).

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

7x - 2z = 4 - xy

Bring like terms together,

7x + xy = 4 + 2z

Take x as common from the left side of the equation,

x(7 + y) = 4 + 2z

x = (4 + 2z)/(7 + y)

Hence, the value of the x can be written as (4 + 2z)/(7 + y).

Step-by-step explanation:

Number of years in decade = 10 years

1). When we are calculating the population of Florida between 1840 to 1850,

Number of years between 1850 and 1840 = 1850 - 1840

                                                                      = 10 years

So number of decades between 1840 and 1850 = [tex]\frac{10}{10}[/tex] = 1 decade

2). Number of years between 1840 and 1860 = 1860 - 1840

                                                                           = 20 years

Therefore, number of decades between this gap = [tex]\frac{20}{10}=2[/tex] decades
