Step-by-step explanation:

The rate at which the distance is changing is calculated to be 14.42 miles per hour.

Consider the east direction to be denoted by x and the north direction to be denoted by y, therefore;

dx / dt = 12 mph

dy / dt = 8 mph
x is equal to 4 miles

Consider the distance between them to be s

Time taken by you to travel 4 miles = distance / speed

Time taken by you to travel 4 miles = 4/12 hour

Distance traveled by the friend in that time = speed × time

Distance traveled by the friend in that time = 8 × (4/12) = 2.67 miles

Now we use the Pythagorean theorem,

x^2 + y^2 + s^2 ...... (1)

Substitute, x = 4 miles and y = 2.67 miles

s^2 = 16 + 7.1289 = 23.1289

s = 4.81

Now differentiate equation 1 with respect to t as follows;

2x (dx/dt) + 2y (dy/dt) = 2s (ds/dt)

2(4) (12) + 2(2.67) (8) = 2 (4.81) (ds/dt)

96 + 42.72 = 9.62 (ds/dt)

138.72 = 9.62 (ds/dt)

ds/dt = 138.72/9.62 = 14.42 miles per hour

Thus the distance is changing at the rate of 14.42 miles per hour.

There were two candidate A and B contesting for the municipal corporation election in a town. The total number of voter in the town were 80,000. If 90% of the voter had voted and 60% of vote polled were cat in favour of A, 28,800 the number of vote received by B.

A state-incorporated city, town, village, or county that has the power to manage local governmental matters, such as creating a police force. A municipal corporation is established by a state's legislature, which also determines its lifespan, privileges, and powers. likewise known as a municipality.

A local governing body, such as cities, counties, towns, townships, charter townships, villages, and boroughs, is referred to legally as a "municipal corporation." Municipally-owned companies can also be referred to as this

Regulation of building construction and land usage. Town planning is included in urban planning. preparing for social and economic progress. water supply for residential, commercial, and industrial uses.

Given that,

Total number voters = 80,000

Total number of votes polled = 90%

Thus,

= (90/100) × 80,000

= 72,000

So, total percent of votes received by B if A gets 60% of polled votes.

= 100% - 60%

= 40%

Hence, total number of votes received by B

= (40/100) × 72,000

= 28,800

Therefore, the number of votes received by B, out of total votes polled is 28,800 votes.

Ann must take out at least 36 fruits from the basket.

Here, we are given that a large basket of fruit contains apples, oranges, and peaches.

Ann has to take out fruits from the basket such that she chooses at least 10 apples, or at least 12 oranges, or at least 14 peaches.

We need to find the least number of fruits that she must take out.

Now, let us assume that she take out 10 fruits. In order to satisfy the condition given, all the 10 fruits must be apples but this may not be always the case.

Thus, the number of fruits is definitely greater than 10.

Similarly, we can notice that the number of fruits is also greater than 12 and 14.

Now, let us say Ann takes out 12 + 14 + 10 = 36 fruits.

In this case, if either all are oranges, apples or peaches, the condition is satisfied. And similarly, you will notice that any combination of fruits will always satisfy the given condition.

Hence, Ann must take out at least 36 fruits from the basket.

what? pls translate it to english

we find that the numerical approximation using Euler's method gives y(2) ≈ 1.865, while the analytical solution gives y(2) = 2.5.

Using the formula y(n+1) = y(n) + Δx * f(x(n), y(n)), where f(x, y) = x² √y, we can calculate the values of y at each step. Here's the step-by-step calculation:

Step 1: For x = 0, y = 1 (initial condition).

Step 2: For x = 0.2, y = 1 + 0.2 * (0.2)² * √1 = 1.008.

Step 3: For x = 0.4, y = 1.008 + 0.2 * (0.4)² * √1.008 = 1.024.

Step 4: For x = 0.6, y = 1.024 + 0.2 * (0.6)² * √1.024 = 1.052.

Step 5: For x = 0.8, y = 1.052 + 0.2 * (0.8)² * √1.052 = 1.094.

Step 6: For x = 1.0, y = 1.094 + 0.2 * (1.0)² * √1.094 = 1.155.

Step 7: For x = 1.2, y = 1.155 + 0.2 * (1.2)² * √1.155 = 1.238.

Step 8: For x = 1.4, y = 1.238 + 0.2 * (1.4)² * √1.238 = 1.346.

Step 9: For x = 1.6, y = 1.346 + 0.2 * (1.6)² * √1.346 = 1.483.

Step 10: For x = 1.8, y = 1.483 + 0.2 * (1.8)² * √1.483 = 1.654.

Step 11: For x = 2.0, y = 1.654 + 0.2 * (2.0)² * √1.654 = 1.865.

Therefore, using Euler's method with a step size of Δx = 0.2, we approximate y(2) to be 1.865.

To obtain the analytical solution to the ODE, we can separate variables and integrate both sides:

∫(1/√y) dy = ∫x² dx

Integrating both sides gives:

2√y = (1/3)x³ + C

Solving for y:

y = (1/4)(x³ + C)²

Using the initial condition y(0) = 1, we can substitute x = 0 and y = 1 to find the value of C:

1 = (1/4)(0³ + C)²

1 = (1/4)C²

4 = C²

C = ±2

Since C can be either 2 or -2, the general solution to the ODE is:

y = (1/4)(x³ + 2)² or y = (1/4)(x³ - 2)²

Now, let's evaluate y(2) using the analytical solution:

y(2) = (1/4)(2³ + 2)² = (1/4)(8 + 2)² = (1/4)(10)² = 2.5

Largest even integer which cannot be written as the sum of two odd composite numbers is 38 if it is divisible by at least one positive integer other than 1 and itself.

The positive even integers which cannot be expressed as the sum of 2 composite odd numbers are: 2,4,6,8,10,12,14,16,20,22,26,28,32,38. This sequence is A118081.

All we have to do now is check the even numbers smaller than  44

. The largest,  42 is a multiple of  3 so it’s handled as  42=9+33 and the next one down,  40 is handled as  40=25+15.But the next one down is our culprit:  38 is not the sum of two odd composite numbers, as you can readily check.

First, what are these “odd composite numbers” anyway? The number  1is considered neither prime nor composite (it’s a unit), so it’s out.  3,5 and  7 are prime. The smallest odd composite number is, therefore,  9 and the next one is  15 .So we have  18=9+9 24=9+1 and  30=15+15 as some even numbers which can be written as a sum of two odd composites, but so far it doesn’t look promising: plenty of even numbers, like  10 or  20 or  32 cannot be so written.

Therefore, the Taylor expansion of the function f(z) = 6(z-1)(z-3) around a = 2 is given by: f(z) = -6 + 12(z-2) + 6(z-2)^2 + ... .

To find the Taylor expansion of the function f(z) = 6(z-1)(z-3), we need to expand it around a chosen point, typically denoted as "a."

Let's expand the function around a = 2 for simplicity. The Taylor expansion formula for a function f(z) centered at a is:

f(z) = f(a) + f'(a)(z-a) + f''(a)(z-a)^2/2! + f'''(a)(z-a)^3/3! + ...

First, let's find the derivatives of f(z):

f'(z) = 6[(z-3) + (z-1)]

= 12z - 12

f''(z) = 12

f'''(z) = 0

Now we can substitute these derivatives into the Taylor expansion formula:

f(z) = f(a) + f'(a)(z-a) + f''(a)(z-a)^2/2! + f'''(a)(z-a)^3/3! + ...

Plugging in a = 2:

f(z) = f(2) + f'(2)(z-2) + f''(2)(z-2)^2/2! + f'''(2)(z-2)^3/3! + ...

Now let's calculate the values of f(2), f'(2), f''(2), and f'''(2):

f(2) = 6(2-1)(2-3) = -6

f'(2) = 12(2) - 12 = 12

f''(2) = 12

f'''(2) = 0

Plugging these values back into the Taylor expansion formula:

f(z) = -6 + 12(z-2) + 12(z-2)^2/2! + 0(z-2)^3/3! + ...

Simplifying:

f(z) = -6 + 12(z-2) + 6(z-2)^2 + ...

Distributive properties.

1/3 x (6x) - 1/3 x 3 - 1/4 x (20x) + 1/4 x 8 = -6

2x - 1 - 5x + 2 = -6
