Answer: third option 60t + 24t

Step-by-step explanation:

Answer: 60\(x^{3}\)-24\(x^{2}\)

Step-by-step explanation:

The first choice is the correct result

Using the vertical line test, the graph that represents a function is: Graph C.

A simple test we can carry out quickly to determine if a graph represents a function is the vertical line test.

Using the vertical line test, a vertical line is drawn across the curve in the given plane. If the vertical line intersect the curve more than once, it is not a function, but if it intersects the curve at just exactly one point, then the graph represents a function.

If we draw a vertical line across each of the given graphs, only the graph in option C will be intersected at exactly only one point.

Therefore, graph C represents a function.

Answer:

There are 68,640 different ways the runners can finish first, second, and third in the race.

Concept of Permutations

The number of different ways the runners can finish first, second, and third in a race can be calculated using the concept of permutations.

Brief Overview

Since there are 42 runners competing for the top three positions, we have 42 choices for the first-place finisher. Once the first-place finisher is determined, there are 41 remaining runners to choose from for the second-place finisher. Similarly, once the first two positions are determined, there are 40 runners left to choose from for the third-place finisher.

Calculations

To calculate the total number of different ways, we multiply the number of choices for each position:

42 choices for the first-place finisher × 41 choices for the second-place finisher × 40 choices for the third-place finisher = 68,640 different ways.

Concluding Sentence

Therefore, there are 68,640 different ways the runners can finish first, second, and third in the race.

In ideal projectile motion, when the positive -axis is chosen to be vertically upward, the -component of the velocity of the object during the ascending part of the motion and the -component of the velocity during the descending part of the motion are b) negative, positive respectively.

In ideal projectile motion, the initial velocity of an object can be separated into its x-component (horizontal) and y-component (vertical). When the positive y-axis is chosen to be vertically upward, the object experiences a constant acceleration due to gravity.

This results in a negative y-component of velocity during the ascending part of the motion (as the object is moving upwards against gravity) and a positive y-component during the descending part of the motion (as the object is falling downwards with gravity).

To summarize, the y-component of velocity is negative during the ascending part of the motion and positive during the descending part. This is because gravity acts downwards, causing the object to slow down as it rises and speed up as it falls.

The distance of a train from the city depends on the speed, the time of

travel, and direction of motion of the train.

Correct responses:

1) From the time of departure of Train B to just before 6 hours after Train B's departure; 0 ≤ t < 6 hours

2) At time period, t > 6 hours

3) 250 miles

Given:

The distance of train A from the city = 750 miles

Speed of train A = 75 mph

Time at which Train B leaves the city = When Train A is 750 miles from the city

Speed of Train B = 50 mph

Solution:

The equations are;

When the train are the same distance from the city, we have;

750 - 75·t = 50·t

750 = 50·t + 75·t = 125·t

Therefore;

The time it takes the two trains to be the same distance from the city is 6 hours.

Which gives;

The distance the trains will be after 6 hours is therefore;

750 - 75 × 6 = 300

The distance of the trains from the city after 6 hours = 300 miles

Therefore, we have;

1) The time period Train A is further from the city is before the first 6 hours elapse; 0 hours ≤ t < 6 hours

2) The Train B is further from the city after 6 hours of its departure from the city; t > 6 hours

3) The distance of Train A from the city after 4 hours is given as follows;

x₁ = 750 - 75 × 4 = 450

x₁ = 450 miles

The distance of Train B from the city after 4 hours is; x₂ = 50 × 4 = 200

According to given,

p = 0.12 (success)

q = 1 - 0.12

  = 0.88 (failure)

x = 7

By applying binomial probability distribution we get -

P(x) = nCx.p^x.q^(n-x)

⇒ P(x=7) = nC7.(0.12)^7.(0.88)^(n-7)

Also given,

Probability of 7 successful trials = 0.77

Thus,

nC7.(0.12)^7.(0.88)^(n-7) = 0.77

⇒ n!/(7! (n-7)!).(0.12)^7.(0.88)^(n-7) = 0.77

⇒ n!/(7! (n-7)!).(0.88)^n = 0.77 * (0.88/0.12)^7

⇒ n!/(7! (n-7)!).(0.88)^n = 878214.711

⇒ n = 130

Answer:

yes

Step-by-step explanation:

Answer:

\(x = 10\)

Step-by-step explanation:

Given

$x per adult

$8 per student

Population:

\(Students = 1\)

\(Adults = 4\)

\(Total = \$48\)

Required

Determine the equation and solve for x

The system can be analyzed as thus:

The cost for 4 adults is: 4 * x

The cost for 1 students is: 8 * 1

Total Amount is: 48

From the analysis above, the equation is:

\(4 * x + 8 * 1 = 48\)

\(4 x + 8 = 48\)

Subtract 8 from both sides

\(4 x + 8 -8= 48 - 8\)

\(4 x= 40\)

Solve for x

\(x = 40/4\)

\(x = 10\)

The given integral is ∫(2x^2 - x + 4)/(x^3 + 4x)dx We can split the numerator into three terms: 2x^2/(x^3 + 4x), -x/(x^3 + 4x), and 4/(x^3 + 4x). Let's begin by evaluating the integral of 2x^2/(x^3 + 4x)dx using u-substitution

From this, we can deduce that dx = du/(3x^2 + 4)Now we can substitute the above values in the integral:

∫2x^2/(x^3 + 4x)dx = ∫(2x^2)/(u)(3x^2 + 4)du/u

= 2/3 ∫du/(u/ x^2 + 4/3)

Let v = u/x^2 and dv/du = 1/x^2.

Therefore, dv = du/x^2.

The third term of the numerator, which is ∫4/(x^3 + 4x)dx can be evaluated using partial fractions:

4/(x^3 + 4x) = A/(x) + B/(x^2 + 4)A(x^2 + 4) + Bx = 4

Using x = 0, we get A = 1 Using x = ±2i, we get B = 1/4i

Therefore, 4/(x^3 + 4x) = 1/x + (1/4i)/(x^2 + 4)∫(2x^2 - x + 4)/(x^3 + 4x)dx

= ∫2x^2/(x^3 + 4x)dx - ∫x/(x^3 + 4x)dx + ∫4/(x^3 + 4x)dx

= 2/3 ln|x^3 + 4x| - ln|x^3 + 4x| - (1/4i) arctan(x/2) + C

= (2/3 - 1) ln|x^3 + 4x| - (1/4i) arctan(x/2) + C

= (1/3) ln|x^3 + 4x| - (1/4i) arctan(x/2) + C

The given differential equation, (x - y³ + y² sin x) dx = (3xy² - 2ycos y)dy, is an exact differential equation.

The Bernoulli's equation, dy y- + x³y = (sin x)y-¹, will not be reduced to a linear equation by using the substitution u = y².

(a) The cost of 1 kg of turnips is £71.95, and

(b) The cost of 1 kg of mushrooms is £89.50.

To solve this problem, let's assign variables to the unknowns.

Let the cost of 1 kg of mushrooms be 'm' and the cost of 1 kg of turnips be 't'.

According to the given information:

Equation 1: 2m + 2.5t = 8.55

Equation 2: 3m + 4t = 13.10

We can solve these equations simultaneously to find the values of 'm' and 't'.

To eliminate the decimals, let's multiply both sides of Equation 1 by 10 and Equation 2 by 20:

20m + 25t = 85.50

60m + 80t = 262.00

Now, let's multiply Equation 1 by 12 and subtract Equation 2 multiplied by 5:

240m + 300t - (60m + 80t) = 1026.00 - 1310.00

180m + 220t = -284.00

We have a new equation:

180m + 220t = -284.00 ---(3)

Next, let's multiply Equation 1 by 18 and subtract Equation 2 multiplied by 4:

36m + 45t - (60m + 80t) = 154.35 - 524.00

-24m - 35t = -369.65

We have another new equation:

-24m - 35t = -369.65 ---(4)

Now, we have a system of linear equations with two variables. Let's solve this system by eliminating one variable.

Multiply Equation 3 by 35 and Equation 4 by 220:

6300m + 7700t = -9940.00 ---(5)

-5280m - 7700t = -81323.00 ---(6)

Adding Equations 5 and 6, we eliminate 't':

1020m = -91263.00

m = -91263.00/1020

m = -89.50

Substituting the value of 'm' back into Equation 3:

180(-89.50) + 220t = -284.00

-16110 + 220t = -284.00

220t = -284.00 + 16110

220t = 15826.00

t = 15826.00/220

t = 71.95.
