Step-by-step explanation:

To find the length of border needed to put around a rectangular room, you can follow these steps:

Measure the length and width of the room using a tape measure or ruler. Let's say the length is L and the width is W.

Determine the type and width of the border you want to put around the room. Let's say you want to use a wallpaper border that is 6 inches wide.

Calculate the length of the border needed for the top and bottom of the room.

This can be done by adding the width of the room to twice the width of the border. So the length of the top and bottom borders would be:

Length of top/bottom borders = 2(W + 6 inches)

Calculate the length of the border needed for the left and right sides of the room. This can be done by adding the length of the room to twice the width of the border. So the length of the left and right borders would be:

Length of left/right borders = 2(L + 6 inches)

Add up the length of all four borders to get the total length of border needed to put around the room:

Total length of border = 2(W + 6 inches) + 2(L + 6 inches)

Simplifying the above equation, we get:

Total length of border = 2L + 2W + 24 inches

So the total length of border needed to put around the room is 2L + 2W + 24 inches.

1)  The domain of Y = 3x⁴ + 4x³ is (-∞, ∞).

2) The x-intercepts are (0, 0) and (-4/3, 0) and the y-intercept is (0, 0)

3)  The horizontal asymptote is y = infinity.

4) Function does not exhibit any symmetry with respect to the y-axis or origin.

5)  The critical points are x = 0 and x = -1.

6)  The critical points are x = 0 and x = -1.

7) The function is concave down on the interval (-∞, -2/3) and concave up on the intervals (-2/3, 0) and (0, ∞).

1) The domain of a polynomial function is all real numbers, so the domain of Y = 3x⁴ + 4x³ is (-∞, ∞).

2) To find the x-intercepts, we set Y equal to zero and solve for x:

0 = 3x⁴ + 4x³

0 = x³(3x + 4)

x = 0 or x = -4/3

Therefore, the x-intercepts are (0, 0) and (-4/3, 0).

To find the y-intercept, we set x equal to zero and solve for Y:

Y = 3(0)⁴ + 4(0)³

Y = 0

Therefore, the y-intercept is (0, 0).

3) Polynomial functions do not have vertical asymptotes. However, as x approaches positive or negative infinity, the function approaches infinity. Therefore, the horizontal asymptote is y = infinity.

4) The function Y = 3x⁴ + 4x³ is neither even nor odd. Therefore, it does not exhibit any symmetry with respect to the y-axis or origin.

5) To find the critical points, we take the first derivative of Y and set it equal to zero:

Y' = 12x³ + 12x²

0 = 12x²(x + 1)

Therefore, the critical points are x = 0 and x = -1.

6) To determine whether the critical points are maxima or minima, we take the second derivative of Y and evaluate it at each critical point:

Y'' = 36x² + 24x

At x = 0, Y'' = 0, which means that the second derivative test is inconclusive. To determine whether x = 0 is a maxima or minima, we look at the sign of the first derivative to the left and right of the critical point. We find that Y' is negative to the left of x = 0 and positive to the right, so x = 0 is a local minimum.

At x = -1, Y'' = 12, which is positive. Therefore, x = -1 is a local minimum.

7) To determine the concavity of the function, we look at the sign of the second derivative:

Y'' = 36x² + 24x

When Y'' > 0, the function is concave up, and when Y'' < 0, the function is concave down.

At x < -2/3, Y'' is negative, so the function is concave down.

At -2/3 < x < 0, Y'' is positive, so the function is concave up.

At x > 0, Y'' is positive, so the function is concave up.

Therefore, the function is concave down on the interval (-∞, -2/3) and concave up on the intervals (-2/3, 0) and (0, ∞).

The maximum profit is $1,892,250.

The profit function is given by[tex]P(x) = -x^2 + 15x + 72x - 300 = -x^2 + 87x - 300.[/tex]

To find the number of hundred thousands of tires that must be sold to maximize profit, we need to find the value of x that maximizes P(x).

We can do this by finding the critical point of P(x) and then checking whether it corresponds to a maximum or a minimum.

The derivative of P(x) is:

P'(x) = -2x + 87

Setting this equal to zero to find critical points, we get:

-2x + 87 = 0

Solving for x, we get:

x = 43.5

Since the problem specifies that x must be at least 5, we know that the critical point x = 43.5 corresponds to a maximum.

Therefore, the number of hundred thousands of tires that must be sold to maximize profit is 43.5.

To find the maximum profit, we substitute x = 43.5 into the profit function:

[tex]P(43.5) = -43.5^2 + 87(43.5) - 300 = 1892.25[/tex]

Since 24.8 minutes is less than 36.4 minutes, you would still meet your goal because your total running time added to your swimming and biking times is less than 100 minutes.

The inequality that represents how many minutes x you can take to finish the running event and still meet your goal is: 18.2 + 45.4 + x < 100. To solve for x, we need to isolate it on one side of the inequality:

18.2 + 45.4 + x < 100
x < 100 - 18.2 - 45.4
x < 36.4

Therefore, you can take no more than 36.4 minutes to finish the running event and still meet your goal of finishing with an overall time of less than 100 minutes.

For question 3, if it takes 8 minutes to run a mile and the running event is 3.1 miles long, it would take you 24.8 minutes to complete the running event. This time is less than the maximum time of 36.4 minutes that you can take to still meet your goal, so yes, this time would allow you to reach your goal.

The area of the semi-circle patio is approximately 17.91 square feet.

To find the area of the semi-circle patio, we need to use the formula for the area of a circle, which is A = πr^2, where π is 3.14 and r is the radius of the circle.

However, since we only have a semi-circle, we need to divide the result by 2 to get the area of the half-circle.

In this case, the radius of the semi-circle is half of the diameter, which is given as 6.75 feet. So, the radius is 6.75/2 = 3.375 feet.

Now, we can plug this value into the formula:

A = (π)(3.375)^2 / 2

A = (3.14)(11.390625) / 2

A = 35.81765625 / 2

Tommy bounces off Joe at a speed of 5.9451 m/s after the collision.

We need to use the conservation of momentum, which states that the total momentum of a closed system remains constant. In this case, the closed system is the two players, Joe and Tommy.

We can start by calculating the initial momentum of the system, which is given by:

[tex]p_{initial} = m_{Tommy} * v_{Tommy} + m_{Joe} * v_{Joe}[/tex]

where m_Tommy and m_Joe are the masses of Tommy and Joe, respectively, and v_Tommy and v_Joe are their initial velocities.

Plugging in the given values, we get:

[tex]p_{initial} = 91 kg * 5 m/s + 97 kg * 6 m/s[/tex]

p_initial = 1123 kgm/s

After the collision, Joe is standing still, which means his velocity is zero. Let's call Tommy's velocity after the collision v_Tommy', which we need to find.

The final momentum of the system is given by:

[tex]p_{final} = m_{Tommy} * v_{Tommy'} + m_{Joe} * 0[/tex]

where we set Joe's velocity to zero since he's standing still.

Since the momentum is conserved, we can equate p_initial and p_final:

p_initial = p_final

[tex]m_Tommy * v_Tommy + m_Joe * v_Joe = m_Tommy * v_Tommy'[/tex][tex]m_{Tommy} * v_{Tommy} + m_{Joe} * v_{Joe} = m_{Tommy} * v_{Tommy'}[/tex]

91 kg * 5 m/s + 97 kg * 6 m/s = 91 kg * v_Tommy'

Solving for v_Tommy', we get:

[tex]v_{Tommy'} = (91 kg * 5 m/s + 97 kg * 6 m/s) / 91 kg[/tex]

v_Tommy' = 5.9451 m/s (rounded to four decimal places)


In summary, we used the conservation of momentum to calculate the velocity of Tommy after bouncing off Joe. We found that he bounces off Joe at a speed of 5.9451 m/s.
