The value of x that makes 25x^2 + 70x + c a perfect square trinomial is c = 1225.

To make the quadratic expression 25x^2 + 70x + c a perfect square trinomial, we need to determine the value of c.

A perfect square trinomial can be written in the form (ax + b)^2, where a is the coefficient of the x^2 term and b is half the coefficient of the x term.

In this case, a = 25, so b = (1/2)(70) = 35.

Expanding (ax + b)^2, we have:

(25x + 35)^2 = 25x^2 + 2(25)(35)x + 35^2

= 25x^2 + 70x + 1225.

Comparing this with the given quadratic expression 25x^2 + 70x + c, we can see that c = 1225.

(a) The sum of everyone's utilities is highest when 2,000 people go After and the rest go Before is not a Nash Equilibrium beacuse it doesn’t meet the criteria for Nash Equilibrium.

(b) The Nash equilibrium number of After 7am drivers is 4000.

(c) A congestion charge of 20 for drivers going after can solve the discrepancy between a and b, as the Nash equilibrium is now met with the 2000 drivers entering after 7 am, and 4000 entering before 7 am.

a) No, it is not a Nash Equilibrium.

Nash Equilibrium is a set of strategies that make sure that no player can improve their own utility by unilaterally changing their strategy.

Therefore, let’s say that all players choose to follow the strategy of entering After 7 am, given that N>4000 people want to drive into Central London. In this scenario, everyone’s utility would be as follows:

u(After) = 50 – 0.01N

However, if a single person changes his strategy and chooses to enter Before 7 am instead, his utility would be 10 instead of the previous 0 (as he is still affected by the congestion even if he enters after).

Thus, the new utility for the person who switched would be greater than what they would have gotten before.

Therefore, this scenario doesn’t meet the criteria for Nash Equilibrium.

b) The Nash equilibrium number of drivers entering after 7 am can be found by the following formula:

50-0.01N=10

40=0.01N

N=4000

which means 4000 people should choose to go Before 7 am, and the rest should go After 7 am.

c) A congestion charge of 20 for drivers going after can solve the discrepancy between a and b.

Let’s say the congestion charge is C. In this case, the utility of entering After 7 am would be

u(After)

=30-0.01(N-A)+20

= 50-0.01N+20-0.01A-20 50-0.01N-0.01A-20 30-0.01N-0.01A

Thus, the Nash Equilibrium number of drivers entering after 7 am would be as follows:

30-0.01N-0.01A=10

20=0.01A

A=2000

N = 4000+2000

N = 6000

Therefore, a congestion charge of 20 for drivers going after can solve the discrepancy between a and b, as the Nash equilibrium is now met with the 2000 drivers entering after 7 am, and 4000 entering before 7 am.

The annual percentage yield, or the effective interest rate, for $1200 invested at 6.63% over 8 years compounded daily is approximately 64.04%.

To determine the annual percentage yield, or the effective interest rate, for $1200 invested at 6.63% over 8 years compounded daily, we can use the formula:
A = P(1 + r/n)^(nt)
Where:
A = the final amount
P = the principal amount (initial investment)
r = the annual interest rate (6.63%)
n = the number of times interest is compounded per year (365 for daily compounding)
t = the number of years (8)
Plugging in the values, we have:
A = 1200(1 + 0.0663/365)^(365*8)
Calculating this, we get A ≈ $1,968.49.
To find the annual percentage yield, we need to find the interest earned:
Interest = A - P = $1,968.49 - $1200 = $768.49
Now, we can find the annual percentage yield using the formula:
Annual percentage yield = (Interest / P) * 100
Plugging in the values, we have:
Annual percentage yield ≈ ($768.49 / $1200) * 100 ≈ 64.04%
Therefore, the annual percentage yield, or the effective interest rate, for $1200 invested at 6.63% over 8 years compounded daily is approximately 64.04%.

The point estimate that can be used to estimate the true mean population is 11.97 inches.

To find the point estimate that can be used to estimate the true population mean, we need to take the sample mean of the given observations. The formula for the sample mean is:

Mod(X)= (Σx) / n

where Mod(X)  is the sample mean, Σx is the sum of all the observations, and n is the size.

Using the given observations, we can calculate the sample mean as follows:

Mod(X) = (11.3 + 10.7 + 12.4 + 15.2 + 10.1 + 12.1 + 16.2 + 10.5 + 11.4 + 11.0 + 10.7 + 12.0) / 12

Answer:

The Linear Program for Sleek Sdn. Bhd. that optimizes profit can be formulated as follows:

Objective Function:

Maximise 25D + 45A

Constraints: 1.5D + 2.5A ≤ 500 (Legs constraint)

                    0.5D + 0.5A ≤ 75 (Labour constraint)

Where,  D = number of Deni stools produced

             A = number of Arni stools produced

To graph the 2-variable Linear Program, we plot the legs constraint and the labour constraint on the graph and shade the feasible region (region that satisfies all the constraints).

Since x1 is unrestricted, we draw the graph with x2 on the horizontal axis and x1 on the vertical axis.

Then, we solve for the intercepts of the two constraints as follows:

                   1.5D + 2.5A = 500

                ⇒ D = (500 - 2.5A)/1.5 and 0.5D + 0.5A = 75

                ⇒ D = 150 - A.

Then, we can form the following table:

                     A D (500 - 2.5A)/1.5 150 - A0 333.33 15050 300 100100 266.67 50

Finally, we plot the points (0,150), (50,100), (100,50), and (266.67,0) on the graph and connect them to form the feasible region.

We can then plot the objective function (profit)

                             25D + 45A = C on the graph and find all the optimal solutions.

Since the objective function is a straight line, we can easily see that there are multiple optimal solutions on the line segment joining (50,100) and (100,50).

We can then read off the corresponding values of D and A to find the optimal solutions.

I HOPE YOU GET IT RIGHT IK ITS THE ANSWERS I ALWAYS DO IT!!!!!!❤

The values of m∠2, m∠4 and m∠6 are 60°, 150° and 90° respectively.

An angle is formed from the intersection of two or more lines. Angles less than 90 degrees are called acute angles, angles greater than 90° are called obtuse angles while angles with a measure of 90° are called right angles.

From the diagram:

m∠1 + m∠4 = 180° (sum of angles in a straight line)

30 + m∠4 = 180°

m∠4 = 150°

m∠2 + m∠5 = 180° (sum of angles in a straight line)

120 + m∠2 = 180°

m∠2 = 60°

m∠1 + m∠2 + m∠3 = 180° (sum of angles in a triangle)

30 + 60 +  m∠3 = 180°

m∠3 = 90

m∠3 + m∠6 = 180° (sum of angles in a straight line)

The limit of the given function as x approaches 2 is 2.

To find the limit of lim x→2x2 − 4 /x2 − 2x, we can simplify the expression by factoring the numerator and denominator:

lim x→2(x+2)(x-2) / x(x-2)

Canceling out the common factor of (x-2), we get:

lim x→2(x+2) / x

Plugging in x=2, we get:

lim x→2(x+2) / x = lim x→2(2+2) / 2 = 4/2 = 2

Therefore, the limit of the given function as x approaches 2 is 2.

Since we were able to simplify the expression without using l'Hospital's Rule, we can say that it was not appropriate to use it in this case. The more elementary method of factoring and simplifying was sufficient.

To find the limit of the given function as x approaches 2, let's first see if we can use an elementary method before considering l'Hospital's Rule.

Given function: (x^2 - 4) / (x^2 - 2x)

Factor the numerator and the denominator:
Numerator: x^2 - 4 = (x - 2)(x + 2)
Denominator: x^2 - 2x = x(x - 2)

Now, simplify the function:
(x - 2)(x + 2) / x(x - 2)

Since (x - 2) is a common factor in both the numerator and the denominator, we can cancel it out:
(x + 2) / x

Now that the function is simplified, we can find the limit as x approaches 2:

lim (x → 2) (x + 2) / x

Plug in 2 for x:
(2 + 2) / 2 = 4 / 2

The limit is 2. In this case, we didn't need to use l'Hospital's Rule as an elementary method was more appropriate.

When the full moon is at position 3, positions 9 and 12 experience low tide.

The correct option is 9 and 12.

The positions of the moon and the sun have an impact on the tides of the Earth's oceans.

What is a tide?

Tides are the regular rise and fall of the sea level due to the gravitational influence of the Moon and the Sun on the Earth. The gravitational pull of the Moon on the Earth produces two tidal bulges, one on the side of the Earth facing the Moon and one on the side opposite the Moon. The Moon's gravitational pull causes high tides in the area of the bulge and low tides elsewhere on the Earth. The tides are affected by the location of the Sun and the Moon as they orbit the Earth.

In order to determine which two positions experience low tide, the Moon's position must be considered.

When the Moon is directly overhead or opposite to the Earth, its gravitational pull has the greatest effect, causing the greatest difference between high and low tides, also known as spring tides.

When the Moon is at a 90-degree angle to the Earth, its gravitational pull is less, causing a smaller difference between high and low tides, also known as neap tides.

In the given case, when the full moon is at position 3, positions 9 and 12 experience low tide.
