Answer: 700.56

Step-by-step explanation:

A heptagon has 7 sides, therfore a regular heptagon will have 7 equal sides

n = 7 (number of sides)

s = 13.9 (length of each sides of the heptagon)

r = 14.4 (The apothem)

The area of the regular heptagon can be calculated by:

Area = ½ n × s × r

Area = ½ × 7 × 13.9 × 14.4

Area = 700.56 square units

Final answer:

The equation of the line that contains the point (-2,1) and has a slope of 4 is y = 4x + 9.

Explanation:

To find the equation of a line that contains a given point and has a given slope, you can use the point-slope form of a linear equation, which is y - y1 = m(x - x1). In this case, the given point is (-2,1) and the given slope is 4. Plugging these values into the point-slope form, we get y - 1 = 4(x - (-2)).

Simplifying the equation, we have y - 1 = 4(x + 2). To get the equation in slope-intercept form, solve for y by distributing 4 to both terms inside the parentheses: y - 1 = 4x + 8. Finally, move the constant term (-1) to the other side of the equation: y = 4x + 8 + 1. The equation of the line is y = 4x + 9.

Step-by-step explanation:

C = 2pir

Divide both sides by 2pi

C/(2pi) = 2pi/2pi r -->

C/(2pi) = r

The required solution of given formula is r = C/(2π). which is the correct answer would be option (D)

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given that formula as:

⇒ C = 2πr

We have to formula solve for r

⇒ C = 2πr

Divide both sides by 22π

⇒ C/(2π) = r2π/2π

⇒ C/(2π) = r or

⇒ r = C/(2π)

Hence, the correct answer would be option (D)

Part A

Sue

A = P*(1+r/n)^(n*t) is the compound interest formula

A = 2300*(1+0.024/1)^(1*3)

A = 2469.6061952

A = 2469.61

A - P = 2469.61-2300 = 169.61

Bill

A = P*(1+r/n)^(n*t)

A = 1800*(1+0.034/1)^(1*3)

A = 1989.9131472

A = 1989.91

A-P = 1989.91-1800 = 189.91

Bill has earned more in interest.

=====================================================

Part B

By year 2, Bill has 1924.48 pounds in his account based on the work shown below

A = P*(1+r/n)^(n*t)

A = 1800*(1+0.034/1)^(1*2)

A = 1924.4808

A = 1924.48

This amount is the new deposit, so to speak, when we change the interest rate. Now r = 0.034 changes to r = 0.04. We only go for one year so t = 1

A = P*(1+r/n)^(n*t)

A = 1924.48*(1+0.04/1)^(1*1)

A = 2001.4592

A = 2001.46

Bill has 2001.46 pounds in his account after 3 years if the interest rate for the 1234 account changes to 4% in the third year.

Now subtract off the original amount Bill deposited to get

2001.46-1800 = 201.46

For this scenario, Bill earns 201.46 pounds in interest.

Therefore, Bill has earned the most interest for both cases of the interest rate staying at 3.4% or changing to 4% for that third year.

Answer:

0.0499

Step-by-step explanation:

This is a binomial probability  function expressed as:

[tex]P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\[/tex]

Given that n =8, and p(male)=1-0.6=0.4, the probability of at least 6 being male is calculated as:

[tex]P(X=x)={n\choose x}p^x(1-p)^{n-x}\\\\P(X\geq 6)=P(X=6)+P(X=7)+P(X=8)\\\\={8\choose 6}0.4^6(0.6)^{2}+{8\choose 7}0.4^7(0.6)^{1}+{8\choose 8}0.4^8(0.6)^{0}\\\\=0.0413+0.0079+0.0007\\\\=0.0499[/tex]

Hence, the probability of at least 6 males is 0.0499

To find the probability of having at least 6 male students in a sample of 8 from a population where 40% are male, you need to calculate the sum of binomial probabilities for 6, 7, and 8 males.

In this problem, we are dealing with the subject of binomial probabilities. Given that 40% of the population are male students (100% - 60% = 40%), we need to find the probability that at least 6 out of 8 randomly selected students are male.

This involves calculating the binomial probability for 6, 7, and 8 males, and then adding them together.

The formula for binomial probability is:

P(X=k) = C(n, k) * (p^k) * ((1-p)^(n-k))

Thus, the probability of getting at least 6 males would be calculated as the sum of the probabilities of getting exactly 6, 7, and 8 males. Before doing the calculations, keep in mind that we would use 0.4 for p (probability of picking a male student) and n=8 (the total number of sampled students).

7. A = 40.8 deg; B = 60.6 deg; C = 78.6 deg

8. A = 20.7 deg; B = 127.2 deg; C = 32.1 deg

Step-by-step explanation:

Law of Cosines

[tex] c^2 = a^2 + b^2 - 2ab \cos C [/tex]

You know the lengths of the sides, so you know a, b, and c. You can use the law of cosines to find C, the measure of angle C.

Then you can use the law of cosines again for each of the other angles. An easier way to solve for angles A and B is, after solving for C with the law of cosines, solve for either A or B with the law of sines and solve for the last angle by the fact that the sum of the measures of the angles of a triangle is 180 deg.

7.

We use the law of cosines to find C.

[tex] 18^2 = 12^2 + 16^2 - 2(12)(16) \cos C [/tex]

[tex] 324 = 144 + 256 - 384 \cos C [/tex]

[tex]-384 \cos C = -76[/tex]

[tex]\cos C = 0.2[/tex]

[tex] C = \cos^{-1} 0.2 [/tex]

[tex] C = 78.6^\circ [/tex]

Now we use the law of sines to find angle A.

Law of Sines

[tex] \dfrac{a}{\sin A} = \dfrac{b}{\sin B} = \dfrac{c}{\sin C} [/tex]

We know c and C. We can solve for a.

[tex] \dfrac{a}{\sin A} = \dfrac{c}{\sin C} [/tex]

[tex] \dfrac{12}{\sin A} = \dfrac{18}{\sin 78.6^\circ} [/tex]

Cross multiply.

[tex] 18 \sin A = 12 \sin 78.6^\circ [/tex]

[tex] \sin A = \dfrac{12 \sin 78.6^\circ}{18} [/tex]

[tex] \sin A = 0.6535 [/tex]

[tex] A = \sin^{-1} 0.6535 [/tex]

[tex] A = 40.8^\circ [/tex]

To find B, we use

m<A + m<B + m<C = 180

40.8 + m<B + 78.6 = 180

m<B = 60.6 deg

8.

I'll use the law of cosines 3 times here to solve for all the angles.

Law of Cosines

[tex] a^2 = b^2 + c^2 - 2bc \cos A [/tex]

[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]

[tex] c^2 = a^2 + b^2 - 2ab \cos C [/tex]

Find angle A:

[tex] a^2 = b^2 + c^2 - 2bc \cos A [/tex]

[tex] 8^2 = 18^2 + 12^2 - 2(18)(12) \cos A [/tex]

[tex] 64 = 468 - 432 \cos A [/tex]

[tex] \cos A = 0.9352 [/tex]

[tex] A = 20.7^\circ [/tex]

Find angle B:

[tex] b^2 = a^2 + c^2 - 2ac \cos B [/tex]

[tex] 18^2 = 8^2 + 12^2 - 2(8)(12) \cos B [/tex]

[tex] 324 = 208 - 192 \cos A [/tex]

[tex] \cos B = -0.6042 [/tex]

[tex] B = 127.2^\circ [/tex]

Find angle C:

[tex] c^2 = a^2 + b^2 - 2ab \cos C [/tex]

[tex] 12^2 = 8^2 + 18^2 - 2(8)(18) \cos B [/tex]

[tex] \cos C = 0.8472 [/tex]

[tex] C = 32.1^\circ [/tex]

Answer:

BC = 12 inches

Step-by-step explanation:

As the triangle is isosceles, we have that AE = CF and EB = FB

If we call AE by x, we have that EB = 2x, FB = 2x and CF = x

As E and D are points tangent to the circle, we have that AE = AD = x

As D and F are points tangent to the circle, we have that CD = CF = x

So if the perimeter is 32, we have that:

AE + EB + BF + FC + CD + DA = 32

x + 2x + 2x + x + x + x = 32

8x = 32

x = 4

The length of BC is equal BF + FC = 2x + x = 3x = 12 inches

Answer:

1/2

Step-by-step explanation:

The first thing you want to do is get y by itself. Subtract 7 from both sides:

2x-4y=-7

and then subtract 2x ( the goal is to make your equation look like this: y=mx+b):

-4y= -2x-7

Now, y is mostly isolated, all you have to do now is divide both sides by -4 in order for y to be completely by itself:

y=-2/-4x -7/-4

Simplify completely:

y=1/2x+7/4

Now you have your equation you can easily read it as y=mx+b.

** m is slope & b is the y-intercept**

So your slope would be: 1/2

The length of minor arc AC is calculated by finding the proportion of the total circumference that the arc's angle represents. In this case, the length of minor arc AC is 3π units.

In circle geometry, the length of an arc (minor arc AC in this case) is proportional to the measure of its central angle. By knowing the central angle and the circumference of the circle, we can calculate the length of the arc. The formula for the circumference of a circle is 2πr, where r is the radius. In this case, AB is the radius, which equals to 15 units. So the circumference of the circle would be 2π * 15 = 30π units.

Now, the measure of the entire circle in terms of degrees is 360º. The measure of AC is given as 36º. Hence, minor arc AC is 36º out of the total 360º, which is (36/360) = 1/10. Therefore, the length of minor arc AC would be 1/10 of the total circumference.

Calculating the length of minor arc AC would be = 1/10 * 30π =  3π units.

The graph of y - 2g(x) - 1 is obtained by applying vertical stretching, reflection, and vertical translation to the original function g(x). The transformed points are (0, -1), (-2, -9), and (4, -5).

To draw the graph of y - 2g(x) - 1, we first need to understand the transformations applied to the original function g(x). The given coordinates (0, 0), (-2, -4), and (4, -2) correspond to points on the graph of g(x).

Now, consider the expression y - 2g(x) - 1. This involves subtracting twice the values of g(x) from y and then subtracting 1. This process suggests vertical stretching, reflection, and vertical translation.

Starting with the points on g(x), let's apply these transformations:

Vertical Stretching: The factor of 2 before g(x) indicates vertical stretching by a factor of 2.

Reflection: The subtraction of 2g(x) reflects the graph over the x-axis.

Vertical Translation: Finally, subtracting 1 shifts the graph downward by 1 unit.

Applying these transformations to the given points, we get the transformed coordinates: (0, -1), (-2, -9), and (4, -5).

Now, plot these transformed points on the graph. Connect the points smoothly to represent the new function y - 2g(x) - 1.

Answer:

El tren tardo 0.82 minutos .

To calculate the travel time of the train, we subtract the departure time (07:34) from the arrival time (08:16), which equals 42 minutes. Thus, the duration of the train's journey is 42 minutes.

Calculating Travel Time:

The given problem is a straightforward task of subtracting the time the train left from the time it arrived at its destination. The train leaves at 07:34 and arrives at 08:16. To find out how long the journey took, we simply calculate the difference in time.

To perform the calculation, convert the times into a 24-hour format if they are not already. Since both times are in the morning, we just need to calculate the minutes. From 34 minutes past the hour to 60 minutes past the hour is 26 minutes. Then, there are an additional 16 minutes from 08:00 to 08:16. Add these two segments together to find the total duration of the trip.

The total duration is 26 minutes + 16 minutes = 42 minutes.

Therefore, it took the train 42 minutes to reach its destination.

Answer:

There is a 1/2 chance of getting tails on the coin and there is 3/8 chance of the spinner landing on red. hope this helps

Final answer:

To find the probability of "tails" on the coin, and the spinner landing on red, you should multiply the probability of getting tails (0.5) by the probability of landing on red (0.375), resulting in 0.1875 or 18.75%

Explanation:

The probability of a particular outcome in a compound event (two or more independent events happening together) is the product of the probabilities of the individual events. Tossing a coin has two possible outcomes: heads or tails, each with a probability of 0.5. Spinning a spinner with 8 equal regions, where 3 are red, gives a probability of landing on red as 3 out of 8, which simplifies to 0.375.

Therefore, the probability of getting "tails" on the coin and the spinner landing on red can be calculated by multiplying the probability of getting tails on the coin (0.5) by the probability of the spinner landing on red (0.375):

Probability(Tails and Red) = Probability(Tails) × Probability(Red)

Probability(Tails and Red) = 0.5 × 0.375

Probability(Tails and Red) = 0.1875 or 18.75%
