The solution to the inequality in question is less than or equal to 4300 pounds and 2.6875 cubic yards of sand can be hauled in the truck to still classify as a passenger vehicle.

From the question itself, we can deduce that the inequality is -

Let us assume that the amount of stuff carried by the vehicle is = x

So, the inequality becomes -

= 4200 + x ≤ 8500 pounds

So, if we solve this we will find that the weight of stuff to be carried is going to be -

= x ≤ 8500 - 4200

= x ≤  4300

It should be no more than 4300 pounds.

We can still classify it as a passenger vehicle by carrying only 1.4655 pounds of sand because -

= 2.6875 *1600 = 4300 pounds

This means that by carrying 2.6875 pounds we maintain the rules to remain a passenger vehicle.

The probability that she will choose to use a cab exactly one time is 4/9.

It has been given that In the morning she has 3 transportation choices. And in the evening the same 3 choices.

i) bus

ii) cab

iii) train

Since each choice have an equal chance of being chosen,

The probability of Choosing a bus will be 1/3

The probability of Choosing a cab will be 1/3

The probability of Choosing a train will be 1/3

Now, the Probability of Not Choosing the cab will be the sum of the probabilities of choosing a bus and train i.e, 2/3

Now there will be two possibilities-Either She chooses a cab in the morning and something else in the evening Or She chooses a cab in the evening and something else in the morning.

Therefore, the probability of choosing a cab exactly one time =

( Probability of cab in morning x Probability of no cab in the evening) + (Probability of no cab in morning x Probability of cab in evening)
Probability of choosing a cab exactly once

= 1/3 x 2/3  + 2/3 x 1/3

= 4/9

Therefore, the probability that she will choose to use a cab exactly one time is 4/9.

Answer:

A package that weighs 5 pounds will cost $15 for both options.

Step-by-step explanation:

The equation for the cost of the first shipping option is y = 5 + 2x, where x represents the amount of pounds of the package. The cost, y, increases by $2 per pound of the package. So, if the package weighs 5 pounds, the cost of the first option would be y = 5 + 2 * 5 = $15.

The equation for the second shipping option is y = 15, representing a one-time fee of $15 to send the box. The cost is fixed at $15 regardless of the weight of the package.

Therefore, if the package weighs 5 pounds, the cost of both shipping options would be $15, and the two options would cost the same.

The work done by the gas on the walls of the cylinder is zero, since the piston is held in place. The heat energy added to the gas will cause it to expand, but since the cylinder has a fixed volume, the pressure of the gas will increase without the gas doing any work on the walls of the cylinder.

An ideal gas is a hypothetical gas which follows the ideal gas laws. These laws state that the pressure, volume, and temperature of an ideal gas are related to each other in a predictable and measurable way. In this case, the cylinder has a fixed length and diameter, and the piston is held in place. This means that the volume of the cylinder is fixed and cannot change, even if heat is added to the gas. Therefore, when 80 J of heat is added, the pressure of the gas will increase, but the gas will not do any work on the walls of the cylinder since it cannot expand. Therefore, the work done by the gas on the walls of the cylinder is zero.

What is Derivative?

Calculus defines a derivative as the rate at which one quantity, y, changes in relation to another, x. The differential coefficient of y with respect to x is another name for it. Finding a function's derivative is the process of differentiation. A function's derivative is typically represented by d/dx (f(x)) (or df/dx (or Df(x) (or f')). Let's examine the technical definition of a derivative. Two points on a function f(x) curve are (x, f(x)) and ((x + h), f(x + h)), respectively. If so, [f(x + h) - f(x)]/(x + h - x) = [f(x + h) - f(x) / h] will be the slope of the secant line through these points. The second point overlaps the first point in the figure below when the distance between two points is nearly equal to 0 (i.e., as h approaches 0), and the secant line turns into the tangent line. Calculus refers to the slope of the tangent line as the function's derivative.

The formula v · v = kvk2 can be seen to hold for all vectors in Rn, as the dot product of a vector and itself is equal to the magnitude of the vector squared.

The formula v · v = kvk2 is true for all vectors v in Rn. This is because the dot product of a vector and itself is equal to the magnitude of the vector squared. The dot product of two vectors is defined as the sum of the products of their components. Therefore, when a vector v is multiplied by itself, the result is the sum of the squares of all its components. The magnitude of a vector is defined as the square root of the sum of the squares of its components.

The graph of y=16x2 is a parabola that is symmetric about the y-axis and opens upwards. Its vertex is at (0,0) and its intercepts are at (0,0) and (±√16,0). As x increases, the graph increases at a faster rate.

The graph of y=16x2 is a parabola that is symmetric about the y-axis and opens upwards. The vertex of the parabola is the point (0,0), which is the point where the parabola changes direction. The y-intercept of the graph is the point (0,0) and the x-intercepts are the points (±√16,0). This means that the graph crosses the x-axis at x=±√16.  As x increases, the graph increases at a faster rate. This is because the exponent of x is 2, meaning that the graph is a quadratic equation. When x=0, the graph is at 0, and as x gets larger, the graph increases more quickly. The graph reaches its maximum at x=√16, where y=16. From this point, the graph decreases until it reaches 0 again at x=-√16.

Answer:

  g(x) = 2x +1

Step-by-step explanation:

You want the complete table and the linear function that describes it, given the points (x, g(x)) = (-3, -5) and (-1, -1).

We note the differences between the x-values shown are -1 -(-3) = 2. The corresponding differences between those y-values is -1 -(-5) = 4.

This lets us fill in the values for x=1 and x=3 as being -1+4 = 3, and 3+4 = 7

We observe that the missing x-value corresponds to g(x)=1, which is halfway between g(x)=-1 and g(x)=3. That means its corresponding x-value will be halfway between x=-1 and x=1, at x=0.

The table is shown in the attachment.

The change in g(x) being 4 when the change in x is 2 means the slope is 4/2 = 2. The y-value of 1 when x=0 means the y-intercept is 1.

These are used to write the slope-intercept form of the equation:

  y = mx +b . . . . . . slope is m, y-intercept is b

For a slope of 2 and a y-intercept of 1, the equation is ...

  y = 2x +1

When we write that in "functional form", the expression g(x) replaces y:

  g(x) = 2x +1

A right angled triangle is a triangle with 90°. Since of one of the angle is 45° , this means that the triangle is isosceles and the other two sides will be equal. This means a= b

Area of triangle = 1/2absinC

The bacteria will reach its maximum size at t = 8.94 weeks.

To find when the bacteria will reach its maximum size, we need to find the maximum value of p(t). The first step is to find the derivative of p(t):

dp(t)/dt = -8000(t^2 - 80)/(80 + t^2)^2

Next, we need to find the critical points of this derivative by setting it equal to 0 and solving for t:

dp(t)/dt = 0

-8000(t^2 - 80)/(80 + t^2)^2 = 0

t^2 - 80 = 0

t = √80

t = 4√5

t ≈ 8.94

Since t = 4√5 is the only critical point, we can see that it is a local maximum. To confirm this, we need to find the second derivative and evaluate it at t = 0:

d^2p(t)/dt^2 = 16000t (t^2 - 240) / (80 + t^2)^3

d^2p(t)/dt^2 = 160000 * -160 / (80 + 80)^3 < 0

Since the second derivative at t =  4√5 is less than 0, it is a local maximum.

ln t = 145.69 days day will 125  people be infected with the virus (500/125)/-.005 = t

This question uses the theory of exponential growth and decay.

The equation y=500/1990e^-. 5(t) models the spread of a flu virus through a population, where y is the total number of people infected after t days.

The equation follows an exponential decay curve, where the number of people infected decreases with each passing day. In this case, the rate of decay is -.005.

given below

Step 1: Rearrange the equation to isolate t.

y = 500/1990e^-.005(t)

500/y = 1990e^-.005(t)

500/y = e^-.005(t)

ln(500/y) = -.005(t)

Step 2: Substitute the given values of y (125) and solve for t.

ln(500/125) = -.005(t)

ln(500/125)/-.005 = t

t = 145.69 days
