a. The value of h'(3) is 45.

b. The value of H'(1) is 36.

The complete table is in the attachment. h' and H are derivates from function h(x) and H(x). Using the Chain Rules to derivate the function.

Calculate the h'(x) function

h(x) = f(g(x))

h'(x) = d/dx {f(g(x))}

h'(x) = f' (g(x)) × g'(x)

h'(3) = f' (g(3)) × g'(3)

h'(3) = f'(2) × 9

h'(3) = 5 × 9

h'(3) = 45

Calculate the H'(x) function

H(x) = g(f(x))

H'(x) = d/dx {g(f(x))}

H'(x) = g' (f(x)) × f'(x)

H'(1) = g' (f(1)) × f'(1)

H'(1) = g'(3) × 4

H'(1) = 9 × 4

H'(1) = 36

We can use the formula d = rt to find the number of hours Kelia traveled.

Given:

Rate (r) = 72 miles per hour

Distance (d) = 414 miles

Using the formula d = rt, we can rearrange it to solve for time (t):

t = d / r

Substituting the given values, we have:

t = 414 miles / 72 miles per hour

Dividing the distance by the rate, we get:

t ≈ 5.75 hours

Therefore, Keila traveled for approximately 5.75 hours.

The distance between point A and C is 10 units.

To find the distance between two points in a plane, we use the distance formula, which is given as:

d = \(\sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2} }\)

Here, point A has coordinates (-2,4) and point C has coordinates (-2,-6).

Substituting the values into the formula, we get:

d = \(\sqrt{(-2-(-2)))^{2}+(-6-4)^{2} }\)

= \(\sqrt{0^{2} +(-10)^{2} }\)

= \(\sqrt{100}\)

= 10

Therefore, the distance between point A and point C is 10 units.

Geometrically, we can visualize the points A and C on a coordinate plane. Point A is located at x = -2 and y = 4, while point C is located at x = -2 and y = -6. Since both points have the same x-coordinate, they lie on a vertical line. The distance between them is the vertical distance between their y-coordinates, which is equal to 10 units.

The cab ride for the 3.8 mile trip is $8.4 .

Slope tells how vertical a line is.

The more the slope is, the more the line is vertical. When slope is zero, the line is horizontal.

To find the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.

the points are (3, 7.90) and (9, 18.70)

y = mx + b

m = y2-y1/x2-x1

m = (18.70 - 7.90)/(9-3)

m = 10.8/6

m = 1.8

y = 1.8x + b

Put the values of x and y to find b ;

y = 1.8x + b

18.70 = 1.8(9) + b

10.5=8.75 + b

b=1.75

The equation of the line is y = 1.8x + 1.75

y=(1.8 X 3.8) + 1.75

y=6.65+1.75

y=8.4

Thus, The cab ride for the 3.8 mile trip is $8.4 .

Using linear function to solve this problem, for every 1 gallon of gas, Francisco travelled 27.9 miles

A linear function is a function that represents a straight line on the coordinate plane. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function. Since y can be replaced with f(x), this function can be written as f(x) = 3x - 2. A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line. where m is slope of the line and b is the y - intercept

We can use the data given in writing out our equation

We can calculate the probability that a person diagnosed with a cough is infected with COVID-19. The probability is found to be approximately 0.0025 or 0.25%.

To solve for the probability that a person diagnosed with a cough is infected with COVID-19, we can use Bayes' theorem. Let's denote A as the event of being infected with COVID-19, and B as the event of having a cough. We are interested in finding P(A|B), the probability of being infected with COVID-19 given that the person has a cough.

According to Bayes' theorem:

P(A|B) = (P(B|A) * P(A)) / P(B)

P(B|A) is the probability of having a cough given that a person is infected with COVID-19, which is stated as 50% or 0.5.

P(A) is the prior probability of being infected with COVID-19, which is given as 1/200 or 0.005.

P(B) is the probability of having a cough, which can be calculated using the law of total probability:

P(B) = P(B|A) * P(A) + P(B|not A) * P(not A)

= (0.5 * 0.005) + (0.2 * 0.995)

= 0.0025 + 0.199

= 0.2015

Plugging these values into Bayes' theorem:

P(A|B) = (0.5 * 0.005) / 0.2015

= 0.0025 / 0.2015

≈ 0.0124 or 0.25%

Therefore, the probability that a person diagnosed with a cough is infected with COVID-19 is approximately 0.0025 or 0.25%.

The surface element is

dS = || ∂r/∂u  x  ∂r/dv || du dv

where

r (u, v) = x (u, v) i + y (u, v) j + z (u, v) k

r (u, v) = (u + v) i + (u - v) j + (1 + 2u + v) k

is the vector parameterization for the surface S.

The normal vector to the surface is

∂r/∂u  x  ∂r/dv

… = (i + j + 2 k)  x  (i - j + k)

… = 3 i + j - 2 k

and has norm

|| ∂r/∂u  x  ∂r/dv || = √(3² + 1² + (-2)²) = √(14)

Now compute the integral:

∫∫ (x + y + z) dS = √(14) ∫₀¹ ∫₀² ((u + v) + (u - v) + (1 + 2u + v)) du dv

The court should not rule in favor of the owner, as the ordinance is likely constitutional. The ordinance is likely to be upheld as an exercise of the city's police power, which grants local governments the authority to pass laws and regulations in the interests of public health, safety, and welfare.

Furthermore, the ordinance does not appear to be an unreasonable exercise of the city's police power, as the installation of seismographic equipment is likely to benefit the public interest by providing early warning in the event of an earthquake. Moreover, the ordinance does not appear to be overly burdensome on the owner, as the cost of the purchase and installation of the equipment is to be borne by a private university, and the owner will not be compensated.

In short, the ordinance does not appear to be an unconstitutional taking of private property, as the owner's burden is minimal and the public benefit is substantial.

The value that the linear equation predicts for the year 2001 is 4652.15

The discrepancy between the actual and anticipated value is 2173.85

Given data;

Here, we present the dataset from the United Nations, which contains information on the number of kilowatt-hours of wind energy generated globally. The data set provides statistics on the US for 25 years, from 1990 to 2014, in millions of kilowatt-hours.

The linear equation for the first 11 years of data, from 1990 to 2000, must be determined.

To determine how much the actual value and anticipated value for the year 2001 differ in Quantity, we must first forecast the value for the year 2001 using our fitted equation with y-intercept.

It will be written as y = m(x) + c.

where,

The dependent variable is y. (in our example is quantity)

The independent variable is x. (in our example is the year)

'm' is equal to the slope of the variable X.

'C' is a constant.

The fitted equation is provided as follows:

Quantity = 186.87 (year) - 369274.72

Now that the value for the year 2001 has been provided,

Quantity = -1868.87 -369274.72 

Quantity = 4652.15

The value that the linear equation predicts for the year 2001 is 4652.15.

The precise figure for 2001 is 6806.

For the year 2001, the discrepancy between the actual and anticipated values is

6806 - 4652.15 = 2173.85

The distinction is 2173.85.

(2173.85/6806)*100 is the percentage difference.

As a result, the difference between the actual value and the forecasted value for the year 2001 is 31.94%.

Hence,

The value that the linear equation predicts for the year 2001 is 4652.15

The discrepancy between the actual and anticipated value is 2173.85

Step-by-step explanation: 18x - 42y = 1    

The supplementary angles to 27° will be 153°.

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. The sum of complimentary angles is 90 degrees. If the two additional angles are combined, they create a straight line and an angle.

However, it should be emphasized that the two complementary angles do not necessarily need to be close to one another. As a result, any two angles can be supplementary if their sum is 180 degrees.
