The area of the triangle with three points spaced equally around a circle of radius 1 is 8√3.

The area of the triangle can be calculated using Heron's formula:

Area = √(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle and a, b, c are the side lengths.

The semiperimeter can be calculated as follows:

s = (a + b + c)/2

For this triangle, the side lengths are:

2, 2√2, and 2

Therefore, the semiperimeter is

s = (2 + 2√2 + 2)/2 = 4√2

The area of the triangle is then:

Area = √(4√2(4√2-2)(4√2-2√2)(4√2-2))

    = √(4√2*2√2*2*2)

    = 8√3

The area of the triangle with three points spaced equally around a circle of radius 1 is 8√3.

Step-by-step explanation:

The number of positive integers less than 1000 that are neither 7-nice nor 8-nice is 749.

N = (ke1 + 1)(ke2 + 1)· · ·(kei + 1).

This means we must have N ≡ 1 (mod k).

Yes, choose a = 2^N−1/k so that

a^k = 2^N−1

, which has N divisors.

So, we need to find the number of integers that are neither 1 mod 7

nor 1 mod 8.

We can use the principle of inclusion and exclusion.

There are [999/7]= 143 integers that are 1 mod 7.

There are [999/8]= 125 integers that are 1 mod 8.

There are [999/56 ]= 18 integers that are 1 mod 56.

By PIE, the answer is 999 − 143 − 125 + 18 = 749.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the equivalent positive numbers are the negative numbers. The boldface Z is a common way to represent the set of integers in mathematical terms.

The interest generated in Pauls savings account is $4.68

The amount generated in Larissa's savings account is $5015.80

Compound interest is interest that builds up over a certain length of time on both principal and interest. The principle is also used to account for the interest that has accrued on a principal over time. Furthermore, the cumulative principal value is used to calculate interest for the subsequent time period. The new way of calculating interest now utilized in all international financial and commercial operations is known as compound interest. When we look at the compound interest values that have built over various time periods, the power of compounding is clearly apparent.

The interest that is paid on both principle and interest and is compounded on a regular basis is known as compound interest. The interest is calculated for the new principal at regular intervals when the accumulated interest and the current principal are combined. The initial principal plus the interest that has already accrued make up the new principal.

The initial principal(p) of Paul is $1000

rate(r) is 5.5%

Number of days(t) = 20th March to 20th April = 31 days = 31/365 years

So the Amount generated =[tex]p * (1 + \frac{r}{365})\x^{365*t}[/tex]

⇒ A = [tex]1000* (1 + \frac{5.5}{100*365})\x^{31} = 1000*1.00468 = 1004.68[/tex]

The interest generated = 1004.68 - 1000 = $4.68

Similarly for Larissa

time = 24th Feb to 17th March = 21 days = 21/365 years

So the Amount generated =[tex]p * (1 + \frac{r}{365})\x^{365*t}[/tex]

⇒ A = [tex]5000* (1 + \frac{5.5}{100*365})\x^{21} = 5000*1.00317 = 5015.80[/tex]

The probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.

The Central Limit Theorem states that the distribution of the mean of a large sample (n>30) taken from a population with a finite mean and standard deviation will be approximately normal.

Since we are given that systolic blood pressures are normally distributed and we have n = 23>30, we can assume that the mean systolic blood pressure of 23 women will be approximately normally distributed with a mean of 114.8 mm Hg and a standard deviation of 13.1/[tex]\sqrt{23}[/tex] = 2.731 mm Hg.

To find the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg, we can standardize the problem and use the standard normal distribution table.

We can standardize the problem by finding the number of standard deviations away from the mean of the lower and upper bounds of the range.

z_lower = (119 - 114.8) / 2.731) = 1.537

z_upper = (122 - 114.8) / 2.731) = 2.636

Now we can use the standard normal distribution table to find the probability that a standard normal variable is between z_lower and z_upper.

P(z_lower < Z < z_upper) = P(Z ≤ 2.636) - P(Z < 1.537) = 0.9958 - 0.9379 = 0.0579

Therefore, the probability that the mean systolic blood pressure of 23 women is between 119 and 122 mm Hg is 0.0579.

Answer:

Let the width equal x Let the length equal x + 3 Next, the formula for determining the perimeter of a rectangle is as follows: P = 2 (L + W) or P = 2 (L) + 2 (W) where P equals the perimeter, L equals the length, and W equals the width.

Step-by-step explanation:

The length of the rectangle is 18.75 inches and the breadth of the rectangle is 6.25 inches.

Let,         the breadth of the rectangle (b)= x

      then the length of the rectangle (l) = 3x    

                                                        (since the length is 3 times its breadth)

We know that the perimeter of a rectangle (p) = 2 (l+b)

                 where, l = length of the rectangle

                             b = breadth of the rectangle  

According to the question,   P = 50

                          P = 2 (l+ b)

                                                       (Put all the values in the equation)

                         50 = 2(3x + x)

                         50 = 2(4x)

                         8x = 50

                           x = 50/8

                              = 6.25

        if x =6.25, then 3x = 3* 6.25 = 18.75

Hence, the length of the rectangle is 18.75 inches and the breadth of the rectangle is 6.25 inches.

Answer: 51.5 degrees

Step-by-step explanation:

The measure of the included angle is about 51.5 degrees. To find this, we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides of the triangle. So, we can set up an equation using the information given: (area)/(0.5*(1.1)(6.6)) = (sin(x)) where x is the included angle. We know that area is 2, so we can put it in the equation: (2)/(0.5(1.1)(6.6)) = (sin(x)) .

Then using sin(x) = 2/(0.5(1.1)*(6.6)) , we can use a calculator to find the sin(x) = 0.094.

and then using a calculator, we can find that x = sin^-1 (0.094) ≈ 5.2 radians. To convert it to degrees, we can multiply it by 180/π ≈ 57.3. So the measure of the included angle is about 57.3 degrees. To the nearest tenth of a degree, it is 57.3, but it can also be rounded off to 51.5 degrees.

Answer:

y = x + 11

Step-by-step explanation:

the equation of a straight line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 14 ) and (x₂, y₂ ) = (9, 20 )

m = [tex]\frac{20-14}{9-3}[/tex] = [tex]\frac{6}{6}[/tex] = 1 , then

y = x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (3, 14 )

14 = 3 + c ⇒ c = 14 - 3 = 11

y = x + 11 ← equation of line

A line passes through points (3,14) and (9,20), linear function rule in terms of x and y for this line is y = x + 11

A linear function in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. The slope of a line passing through two points (x1, y1) and (x2, y2) can be found using the formula: m = (y2 - y1) / (x2 - x1). Plugging in the point values from the problem, we get:m = (20 - 14) / (9 - 3) = 6/6 = 1

The y-intercept  be found by plugging in any one of the point values and the slope into the equation y = mx + b and solving for b. Using the point (3,14), we get:

14 = 1*3 + b

b = 11So the linear function in terms of x and y is:

y = x + 11

A linear function is a type of mathematical function that, when graphed, defines a straight line. It is defined by the equation y = mx + b, where x and y are variables, m is the line's slope, and b is the y-intercept (the point where the line crosses the y-axis). The slope (m) of the line represents its steepness, and the y-intercept (b) represents the point at which the line intersects the y-axis.

Total distance: 163 miles + 411 miles

= 574 miles

Average speed: 574 miles / (10 hours 16 minutes)

= 226.4 miles per hour

To calculate the average speed of the Copeland family's trip so far, we need to know the total distance they have traveled and the total time they have spent traveling. We can calculate this by adding the distance driven by Mr. Copeland (163 miles) and the distance driven by Mrs. Copeland (411 miles) to get a total distance of 574 miles. Then, we can add the time taken by Mr. Copeland (3 hours 49 minutes) and the time taken by Mrs. Copeland (6 hours 27 minutes) to get a total time of 10 hours 16 minutes. We can then divide the total distance (574 miles) by the total time (10 hours 16 minutes) to get an average speed of 226.4 miles per hour.
