The average rate of change of the traffic flow over the time interval 10 < t < 15 is 0.1085 cars per minute. Since this value is positive, the traffic flow is increasing over this time interval.

The traffic flow at the intersection is modeled by the function F(t) = 82 - 4sin(t) for 0 < t < 30, where F(t) is measured in cars per minute and t is measured in minutes.

To find the total number of cars that pass through the intersection over the 30-minute period, we can integrate the function over the time interval from 0 to 30 minutes. The integral of the function is given by:

∫F(t)dt = ∫(82 - 4sin(t))dt

= 82t - 4cos(t) + C

Evaluating this integral at t = 0 and t = 30, we get:

82(0) - 4cos(0) + C = 0

82(30) - 4cos(30) + C = 2184

Solving for C, we get C = -246.

Substituting this value back into the integral equation, we get:

∫F(t)dt = 82t - 4cos(t) - 246

Plugging in t = 30, we get:

∫F(t)dt = 82(30) - 4cos(30) - 246 = 2184 - 246 = 1939

Therefore, the total number of cars that pass through the intersection over the 30-minute period is 1939 cars.

To determine whether the traffic flow is increasing or decreasing over the time interval 10 < t < 15, we can find the average rate of change of the traffic flow over this time interval. The average rate of change is given by:

(F(t2) - F(t1))/(t2 - t1)

Plugging in t1 = 10 and t2 = 15, we get:

(F(15) - F(10))/(15 - 10)

= (82 - 4sin(15) - (82 - 4sin(10)))/(5)

= (-4sin(15) + 4sin(10))/5

= (-4(√(6)/4) + 4(1/2))/5

= (-√(6) + 2)/5

= (-1.4575 + 2)/5

= 0.5425/5

= 0.1085

The units of measure for the average rate of change are cars per minute.

Answer:

The answer is the range of the function y = x + 3 when the domain is {-2, 0, 4}, which is the set {1, 3, 7}.

Step-by-step explanation:

The range of the function y = x + 3 is the set of all possible values of y for a given value of x in the domain of the function. In this case, the domain of the function is the set {-2, 0, 4}, so the range of the function is the set of all possible values of y for x equal to -2, 0, and 4.

To find the range, we need to substitute each of these values of x into the equation y = x + 3 and solve for y. When x = -2, we have y = -2 + 3 = 1. When x = 0, we have y = 0 + 3 = 3. And when x = 4, we have y = 4 + 3 = 7. Therefore, the range of the function y = x + 3 when the domain is {-2, 0, 4} is the set {1, 3, 7}.

The likelihood that a random cumulative variable will fall within a specific range of values rather than taking on a single value is specified by the Probability Density Function.

The probability density function (PDF), also known as the density of a continuous random variable, is a function whose value at any specific sample (or point) in the data point (the range of potential values for the random variable) can be understood as having given a relative likelihood that the value of something similar to the random variable would be closer to that sample.

There is no absolute probability that a random variable will take on any specific value because there are an unlimited number of alternative values to begin with. However, the PDF value at two samples can be used to estimate how much more likely it is for the random variable to have that particular value in any given draw.

The Cantor distribution, which although having no discrete component, does not assign positive probabilities to any specific locations, and discrete random variable probability distributions do not all have a density function.

A distribution has a density function if and only if the cumulative distribution function F(x) is fully continuous. In this case, F is typically always differentiable, and its derivative can be used to symbolize the probability density.

Answer: 10 marbles

Step-by-step explanation:

First, arrange all the numbers of marbles that the student picked in a ratio

red:green:blue

7:2:11

When adding all the coloured marbles that the student picked together, you get 20 marbles or "parts" as you would usually say in ratio.

Then, it would be helpful to rewrite the ratios as fractions, with 20 as the denominator:

[tex]\frac{7}{20}:\frac{2}{20}:\frac{11}{20}[/tex]

However, the bag contains 100 marbles so we should have 100 as the denominator instead of 20.  20 is a fifth of 100, so in this case, we would multiply everything (the numerator and the denominator) by 5:

[tex]\frac{7*5}{20*5} :\frac{2*5}{20*5} :\frac{11*5}{20*5}[/tex]

[tex]\frac{35}{100}:\frac{10}{100}:\frac{55}{100}[/tex]

Therefore, you could predict you would get 35 red marbles, 10 green marbles, and 55 blue marbles.

the work done by the force F on a particle moving counterclockwise around the closed path C is 9π by integral.

Green's Theorem states that:

∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA

Where C is the boundary of the region D, P and Q are the components of the vector field F, and dr is the vector differential along the boundary C.

In this case, the region D is a circle with radius 2, so we can express the boundary C as r = 2 cos θ. We also need to calculate the components of the vector field F. These are P = e^x - 3y and Q = e^y + 6x.

Plugging these values into Green's Theorem, we get integral:

∮C F · dr = ∫∫D (∂Q/∂x - ∂P/∂y) dA

= ∫∫D (e^y + 6 - (-3)) dA

= ∫∫D (e^y + 9) dA

In the given question, Bart is required to pass out 80 flyers for an upcoming event. He passes out an average of 10 flyers per minute.

The situation can be represented using the function f(x)=80-10x

where x represents time in minutes.

We have to create a graph of the situation.

To create the graph we firstly find the value of f(x) for x=0,1,2,3,..............

The given function is f(x) = 80-10x

Now put x = 0

So f(0) = 80-10(0)

f(0) = 80-0

f(0) = 80

Now put x = 1

So f(1) = 80-10(1)

f(1) = 80-10

f(1) = 70

Now put x = 2

So f(2) = 80-10(2)

f(2) = 80-20

f(2) = 60

Now put x = 3

So f(3) = 80-10(3)

f(3) = 80-30

f(3) = 50

Now put x = 4

So f(4) = 80-10(4)

f(4) = 80-40

f(4) = 40

Now the table is

Answer:

$420

Step-by-step explanation:

To find the original price, we need to determine how much the sale price was discounted, and then add that amount back to the sale price. Since the sale price was 68% less than the original price, the discount was 100% - 68% = 32% of the original price.

To find the amount of the discount, we multiply the original price by the discount percentage: 32% * original price = $134.40

Dividing both sides of the equation by the discount percentage gives us the original price: original price = $134.40 / (32% * 1) = $134.40 / 32% = $420.

Therefore, the original price of the sofa was $420.

The two bodies are being drawn together by a force of 10812 N, according to Newton's Law of Gravitation.

Every particle in the universe is drawn to every other particle with a force that is directly proportional to the product of their masses and inversely proportional to their separation from one another, according to Newton's Law of Universal Gravitation.

Symbolically, Newton came to the following conclusion on the strength of the gravitational force:

F = G(m₁ × m₂) / r²

F is the gravitational force between two bodies, m1 and m2 are the bodies' masses, r is the distance between their centres, and G is the gravitational constant of the universe.

According to the query,

satellite's mass is m1 = 1100 kg.

mass of earth = 5.98 ×10²⁴ kg

Radius of the earth = 6.37 × 10⁶ m

G = 6.67 × 10⁻¹¹ Nm² / kg²

Force = G(m₁ × m₂) / r²

Substituting the values,

F = 6.67 × 10⁻¹¹( 1100 × 5.98 ×10²⁴)  /( 6.37 × 10⁶)²

=> F = 6.67 × 1100 × 5.98 × 10¹³ / 40.58 × 10¹²
