The number of the covid patients before two hours is 39690.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the growth rate of Covid patients is 5% per hour. If the number of Covid patients in the morning at 8:00 am is 44,100.

The growth rate will be calculated as:-

Growth rate = 44100 x 0.05 = 2205

Before 2 hours the number of Covid patients will be:-

Number = 44100 - ( 2 x 2205)

Number = 44100 - 4410

Number = 39690

The value of the definite integral of f(x) over the interval [−1, 5] is estimated to be between 36 and 42.

A function is a mathematical concept that assigns a unique output value for each input value. It is a rule that takes in an input or set of inputs and maps it to a specific output. Functions are represented by symbols, usually denoted by a letter, such as "f".

In mathematical notation, a function is usually expressed as "f(x)" where "x" is the input and "f(x)" is the corresponding output. For example, a function could be defined as f(x) = x^2, which means that for any value of x, the function will calculate and return the square of that value.

Functions play a central role in mathematics and are used to model real-world phenomena and to study the relationships between variables. They are also used in computer programming to perform specific tasks, such as converting temperatures from Celsius to Fahrenheit or calculating the square root of a number.

Since 6≤f(x)≤7 for −1≤x≤5, we have a lower bound of 6 and an upper bound of 7 for the function over this interval. This means that, for any possible value of f(x) in the interval, we can use 6 as a lower estimate and 7 as an upper estimate for the definite integral. Hence, we have:

Lower estimate: ∫5−1 6 dx = 6(5 - (-1)) = 6(6) = 36

Upper estimate: ∫5−1 7 dx = 7(5 - (-1)) = 7(6) = 42

So, the value of the definite integral of f(x) over the interval [−1, 5] is estimated to be between 36 and 42.

The measures of the smallest and the largest possible integral lengths of the third side of the triangle is 21 and 1 respectively

What is Triangle?

A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.

A side of a triangle must be always less than or equal to the sum of other two sides and greater than the difference of other two sides.

Say the required side is x.

So x<9+11 and x>9-11

The complete answers regarding flow of people and occupancy are solved as follows:

(a) The flow of people from downtown to campus is the rate at which the shuttle buses can transport passengers from the downtown bus stop to the campus bus stop.

(b) The flow of people from campus to downtown is equal to the rate at which passengers are coming to the campus bus stop.

(c) The average bus occupancy from campus to downtown is equal to the number of passengers on each bus divided by the number of seats on each bus.

Dispatching the buses from downtown to campus at equal headways would reduce the average waiting time of passengers going from campus to downtown. This is because the slower bus would have more time to pick up and drop off passengers, and the faster bus would not be slowed down by having to wait for the slower bus. The overall result would be a reduction in the average waiting time for all passengers.

Complete Question:

Suppose that two shuttle buses operate (without coordination) between the campus and downtown. One bus can carry 20 people and has a round trip time of 8 min (including loading and unloading passengers), the other can carry 25 people but has a round trip time of 10 min. There is always a queue of people waiting at the downtown bus stop, but passengers come to the campus bus stop at a steady rate of 2/min. If neither bus is idle at any time, determine:

(a) The flow of people from downtown to campus.

(b) The flow of people from campus to downtown.

(c) The average bus occupancy from campus to downtown.

If one insisted on dispatching these buses from downtown to campus at equal headways, we would only slow down the faster bus. Would you expect this strategy to reduce the average waiting time of passengers going from campus to downtown?

Thus, the response is: B) The pavement becomes the new surface (and Earth).

The law of conservation of momentum states that an object's momentum may only be transferred, not created or destroyed, and is equal to its mass times its velocity.

The momentum the car (and its contents) had before braking must go somewhere when it skids to a halt. The friction force between the tyres and the road in this instance causes it to be transferred to the pavement (and Earth). The friction force slows the car down until it comes to a stop by acting in the opposite direction of the car's speed.

A quadrant is one of the four regions into which the plane is divided by the x-axis and y-axis. There are four quadrants in total:

First quadrant (Quadrant I): The values of x and y are both positive.

Second quadrant (Quadrant II): The value of x is negative, and the value of y is positive.

Third quadrant (Quadrant III): Both the values of x and y are negative.

Fourth quadrant (Quadrant IV): The value of x is positive, and the value of y is negative.

The location of a point in a plane can be determined by its coordinates (x, y), and based on the sign of x and y, the point can be located in one of the four quadrants.

The given expression is tan(t)sin(t)/cot(t).

If the terminal point determined by t is in quadrant III (180° < t < 270°), then tan(t) and sin(t) are negative, and cot(t) is positive. In this case, the expression tan(t)sin(t)/cot(t) is negative.

The confidence interval can be expressed as (27.4%, 38.0%).

This confidence interval can be calculated using the formula (X ± z*σ/√n), where X is the sample mean, z is the z-score that corresponds to the desired confidence level (in this case, 95%), σ is the population standard deviation, and n is the sample size.

This is calculated using the formula:

lower bound = point estimate - margin of error and

upper bound = point estimate + margin of error.

In this case, the point estimate is 33.2% and the margin of error is 5.8%.

Therefore, lower bound = 33.2% - 5.8% = 27.4% and

upper bound = 33.2% + 5.8% = 38.0%.

This means that we are 95% confidence interval that the true population proportion lies between 27.4% and 38.0%.

First, solve the equation f'(x) = 0 to identify the critical locations. It will be calculated using the formula [tex]\frac{d}{dx}(xy) = x\frac{d}{dx}(y) + y\frac{d}{dx}(x)[/tex].

f'(x) = [tex](x^2 +1)\frac{d}{dx}e^{-x}+e^{-x} \frac{d}{dx}(x^2+1)[/tex]

f'(x) = [tex]-(x^2 + 1)e^{-x}+2xe^{-x}[/tex]

Taking e^{-x} common

f'(x) = [tex][2x-(x^2+1)]e^{-x}[/tex]

f'(x) = [tex]e^{-x}(-x^2+2x-1)[/tex]

Now equating f'(x) = 0, then

[tex]e^{-x}(-x^2+2x-1)[/tex] = 0

The only essential point is at x = 1 since e^{-x} is zero only at x = ∞.

f(1) = 2e^{-1}.

Trigonometric ratios are the ratios of a right triangle's sides. The sine (sin), cosine (cos), and tangent (tan) are three often used trigonometric ratios. There are other trigonometric ratios which are reciprocals of these ratios.

Sin J =opposite/hypotenuse

Sin J  = √35/ 7

=> J = sin^-1( √35/ 7 )

=> J= 57.68 degrees

tan J = opposite/adjacent = √35/IJ

=> tan (57.68) = √35/IJ  

=> 1.5806 = √35/IJ  

=> IJ = √35 / 1.5806 = 3.74

=> IJ = 37/10

tan J =  √35 / (37/10 ) = (10√35 / 37 )

However hexagons have 2 times as much sides as triangles so to make a triangle you would have to make a line with every other arc. That means skip an arc each line you make.
