Step-by-step explanation:
The high blood pressure of an obese individual can be modelled by the function p()-40 sin 3x + 160, where p(1) represents the blood pressure, in millimetres of mercury (mmHg), and is the time, in seconds. Determine the maximum and minimum blood pressure, in the time interval 0 SIS 0.75, and the time(s) when they occur.
Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.
To find the maximum and minimum values of the blood pressure function p(t), we need to examine the behavior of the sinusoidal term, -40sin(3t), within the given time interval. The function is a sine wave with an amplitude of 40 and a period of 2π/3. This means that the maximum value occurs at the peak of the sine wave (amplitude + offset), and the minimum value occurs at the trough (amplitude - offset).
The maximum blood pressure corresponds to the peak of the sine wave, which is 40 + 160 = 200 mmHg. To find the time at which this occurs, we set the argument of the sine function, 3t, equal to π/2 (since the peak of the sine wave is π/2 radians). Solving for t gives t = (π/2) / 3 = π/6 ≈ 0.524 seconds.
Similarly, the minimum blood pressure corresponds to the trough of the sine wave, which is -40 + 160 = 120 mmHg. Setting the argument of the sine function equal to 3π/2 (the trough of the sine wave), we find t = (3π/2) / 3 = π/2 ≈ 1.571 seconds.
Therefore, the maximum blood pressure of 200 mmHg occurs at approximately 0.524 seconds, and the minimum blood pressure of 120 mmHg occurs at approximately 1.571 seconds within the time interval 0 ≤ t ≤ 0.75.

In sailing, it is not possible to head straight into the wind. In order to get upwind, a sailboat simply sails at an angle to the wind and then turns to sail back toward where it wants to go. Assume that a boat needs to get directly upwind 6000 m. If it sails off at a 45 degree angle to the wind and then turns back 90 degrees towards the original goal, how far would it have to sail to get directly upwind 6000 meters? Round to the nearest tenth.

4242.6
8485.3
10392.3
Answer:
C. 8485.3 meters
Step-by-step explanation:
Think of the sailboat’s path as a 45-45-90 right triangle.
The hypotenuse is the 6000 meter distance.
In this way the leg will be the hypotenuse divided by √2.
So 6000/√2 or 4242.64 meters.
Remember that the sailboat has to turn and head back toward its goal and travel another 4242.64 meters.
Thus, your answer is 4242.64 x 2 = 8485.28 meters or 8485.3 meters.
In this exercise we have to use the knowledge of triangles to calculate the distance that one of the sides has:
Letter C
Some information given in the statement about the triangle:
Sailboat’s path as a 45-45-90 right triangle.The hypotenuse is the 6000 meter distance.So performing the calculation we have:

3. By expressing it as a Taylor series, show that the following function is entire: {(1 f(z) = = { = (1 – cos z) if z #0 if z = 0 =
After considering the given data we conclude that Taylor series is \(f(z) = 1/z^2(1-cos(z)) = 1/z^2 - 1/2! + (z^2/4!) - (z^4/6!) + ...\)
To present that the function f(z) = 1/z^2(1-cos(z)) is entire, we need to express it as a Taylor series.
The Taylor series of f(z) can be evaluated by first elaborating (1-cos(z)) as a power series and then applying division using z². The power series of (1-cos(z)) is:
\(1 - cos(z) = 1 - (z^2/2!) + (z^4/4!) - (z^6/6!) + ...\)
Applying divison using z², we get:
\((1 - cos(z))/z^2 = 1/z^2 - (1/2!)(z^2/ z^2) + (1/4!)(z^4/ z^2) - (1/6!)(z^6/ z^2) + ...\)
Applying simplification , we get:
\((1 - cos(z))/z^2 = 1/z^2 - 1/2! + (z^2/4!) - (z^4/6!) + ...\)
Therefore, the Taylor series of f(z) is:
\(f(z) = 1/z^2(1-cos(z)) = 1/z^2 - 1/2! + (z^2/4!) - (z^4/6!) + ...\)
Since the Taylor series of f(z) converges for all z, except possibly at z = 0, and the function is defined to be 1/2 at z = 0, we can conclude that f(z) is entire.

What is the solution of the inequality shown
below?
y+7≤-1
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
To solve the inequality y + 7 ≤ -1, we need to isolate the variable y on one side of the inequality sign.
Starting with the given inequality:
y + 7 ≤ -1
We can begin by subtracting 7 from both sides of the inequality:
y + 7 - 7 ≤ -1 - 7
y ≤ -8
The solution to the inequality is y ≤ -8. This means that any value of y that is less than or equal to -8 will satisfy the original inequality.
In the context of a number line, all values to the left of -8, including -8 itself, will make the inequality true. For example, -10, -9, -8, -8.5, and any other value less than -8 will satisfy the inequality. However, any value greater than -8 will not satisfy the inequality.

Step-by-step explanation:
The angle in a regular octagon = 180 - (360/8) = 135.
Using trigonometry sin (135/2) = k/2 / EF
sin 67.5 = k / 2EF
2EF = k / sin 67.5
EF = k / 2 sin 67.5 = k/1.8478
Perimeter of octagon = 8 * k/1.8478
= 4.33k to the nearest hundredth.
Write an equation in slope-intercept form of the line that passes through (2,-3) and (- 1/2, 1/8)
Answer:
\(y = - \frac{5}{4} x - \frac{1}{2} \)
Step-by-step explanation:
Slope-intercept form: y= mx +c, where m is the slope and c is the y-intercept.
\(\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }\)
Slope
\( = \frac{ - 3 - \frac{1}{8} }{2 - ( - \frac{1}{2}) } \)
\( = - \frac{5}{4} \)
Substitute the value of m into the equation:
\(y = - \frac{5}{4} x + c\)
To find the value of c, substitute a pair of coordinates the line passes through into the equation.
When x= 2, y= -3,
\( - 3 = - \frac{5}{4} (2) + c\)
\( - 3 = - \frac{5}{2} + c\)
\(c = - 3 + \frac{5}{2} \)
\(c = - \frac{1}{2} \)
Thus, the equation of the line is \(y = - \frac{5}{4} x - \frac{1}{2} \).

Construct a counterexample by model for the following invalid argument, and then explain exactly how your counterexample proves that the argument is invalid.
¼ of the hairs in Plato’s beard are gray. ¾ of the hairs in Aristotle’s beard are gray. So, Aristotle has a greater number of gray hairs in his beard than Plato does.
The given argument is invalid. It says that if one person has more gray hair in their beard than another person, then they have a higher percentage of gray hair in their beard.
The argument is invalid because it is possible for one person to have a higher percentage of gray hair in their beard but a lower number of gray hairs in total.One possible counterexample by model is:Suppose Plato has 200 hairs in his beard and 50 of them are gray. So, 1/4 of his hairs are gray. Now, let's suppose Aristotle has 400 hairs in his beard, and 300 of them are gray. So, 3/4 of his hairs are gray. Even though Plato has fewer gray hairs than Aristotle, his percentage of gray hairs is more significant (1/4) than Aristotle's (3/4).
Therefore, the given argument is invalid since Aristotle's beard contains more gray hairs in quantity, but Plato has a higher percentage of gray hair in his beard.

Tο subtract 2/3 - 1/4, we need tο find a cοmmοn denοminatοr fοr the twο fractiοns. The smallest cοmmοn denοminatοr is 12, sο we'll cοnvert each fractiοn tο an equivalent fractiοn with a denοminatοr οf 12:
2/3 = 8/12 (multiply bοth numeratοr and denοminatοr by 4)
1/4 = 3/12 (multiply bοth numeratοr and denοminatοr by 3)
Nοw we can subtract the twο fractiοns:
8/12 - 3/12 = 5/12
Sο 2/3 - 1/4 = 5/12.
Tο express the result as a fractiοn in the fοrm x/y, we can simply use the answer we fοund: x = 5, y = 12, sο:
2/3 - 1/4 = 5/12 = 5/12
Similarly, tο express the result as a fractiοn in the fοrm a/b, we need tο find anοther equivalent fractiοn with a cοmmοn denοminatοr. We can use 24 as a cοmmοn denοminatοr this time:
2/3 = 16/24 (multiply bοth numeratοr and denοminatοr by 8)
1/4 = 6/24 (multiply bοth numeratοr and denοminatοr by 6)
Nοw we can subtract the twο fractiοns:
16/24 - 6/24 = 10/24
Sο 2/3 - 1/4 = 10/24.
Tο express the result as a fractiοn in the fοrm a/b, we can simplify the fractiοn by dividing bοth numeratοr and denοminatοr by their greatest cοmmοn factοr, which is 2:

The new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees are approximately (4.993, 2.048).
To find the new coordinates of the point (5, 2) after rotating counterclockwise about the origin through an angle of 5 degrees, we can use the rotation formula:
x' = x * cos(theta) - y * sin(theta)
y' = x * sin(theta) + y * cos(theta)
Where (x, y) are the original coordinates, (x', y') are the new coordinates after rotation, and theta is the angle of rotation in radians.
Converting the angle of rotation from degrees to radians:
theta = 5 degrees * (pi/180) ≈ 0.08727 radians
Plugging in the values into the rotation formula:
x' = 5 * cos(0.08727) - 2 * sin(0.08727)
y' = 5 * sin(0.08727) + 2 * cos(0.08727)

R0,180° ∘ T2,0 (x, y)
T0,2 ∘ R0,270°(x, y)
R0,2 ∘ T0,180°(x, y)
The correct rule describing the composition of Transformations is: R0,2 ∘ T0,10 ∘ R0,270°
The rule that describes the composition of transformations mapping rectangle PQRS to P''Q''R''S'', we need to analyze the given coordinates and determine the sequence of transformations.
Let's compare the coordinates of the corresponding points:
P (−3, −5) ↔ P'' (−5, 5)
Q (−2, −5) ↔ Q'' (−5, 4)
R (−2, −1) ↔ R'' (−1, 4)
S (−3, −1) ↔ S'' (−1, 5)
From the comparison, we can observe the following transformations:
1. Translation: The x-coordinate of P'' is obtained by subtracting 2 from the x-coordinate of P. The y-coordinate of P'' is obtained by adding 10 to the y-coordinate of P. This suggests a translation of (−2, 10).
2. Reflection: The x-coordinate of Q'' is obtained by reflecting the x-coordinate of Q across the y-axis. The y-coordinate of Q'' remains the same. This indicates a reflection across the y-axis.
3. Rotation: The coordinates of R'' and S'' are obtained by rotating R and S 270 degrees counterclockwise about the origin (0, 0).
Now, let's determine the composition of transformations:
The sequence of transformations that maps rectangle PQRS to P''Q''R''S'' is as follows:
1. Translation by (−2, 10)
2. Reflection across the y-axis
3. Rotation of 270 degrees counterclockwise about the origin

what is the company's total contribution margin? begin by identifying the formula.
Total contribution margin is an accounting metric that evaluates how well a company's sales income covers its variable expenses. The company's total contribution margin can be found using the formula: Total Contribution Margin = Total Revenue - Total Variable Costs.
To calculate the total contribution margin, follow these steps:
1. Determine the total revenue: This is the amount of money the company makes from selling its products or services. You can find this by multiplying the selling price of each product by the number of units sold.
2. Determine the total variable costs: These are the costs that change depending on the level of production or sales. Examples of variable costs include raw materials, direct labor, and shipping costs. Calculate the variable cost for each product by multiplying the variable cost per unit by the number of units produced or sold.
3. Subtract the total variable costs from the total revenue to find the total contribution margin. This value represents the amount of money the company has remaining after covering its variable costs, which can be used to cover fixed costs and contribute to profit.
So, to calculate the company's total contribution margin, use the formula: Total Contribution Margin = Total Revenue - Total Variable Costs, and follow the steps above.
