Step-by-step explanation:

(i) 2x = 5

compare with ax+by+c = 0

→ 2x + 0.y - 5 = 0

» a = 2 ,b = 0 ,c = -5

(ii) y - 2 = 0

compare with ax + by + c = 0

→ 0.x + 1y -2 = 0

» a = 0 , b = 1 , c = -2

(iii) y/7 = 3

y = 3×7

y = 21

y - 21 = 0

compare with ax + by + c = 0

→ 0.x + 1y -21 = 0

» a = 0 , b = 1 , c = -21

(iv). x = -14/13

13x = -14

13x + 14 = 0

compare with ax + by + c = 0

→ 13x + 0.y + 14 = 0

\(Max\ Area = \frac{x^2}{16}\)

Step-by-step explanation:

Given

\(P = x\) ---- the perimeter of fencing

Required

The maximum area

Let

\(L \to Length\)

\(W \to Width\)

So, we have:

\(P = 2(L + W)\)

This gives:

\(2(L + W) = x\)

Divide by 2

\(L + W = \frac{x}{2}\)

Make L the subject

\(L = \frac{x}{2} - W\)

The area (A) of the fence is:

\(A = L * W\)

Substitute \(L = \frac{x}{2} - W\)

\(A = (\frac{x}{2} - W) * W\)

Open bracket

\(A = \frac{x}{2}W - W^2\)

Differentiate with respect to W

\(A' = \frac{x}{2} - 2W\)

Set to 0

\(\frac{x}{2} - 2W = 0\)

Solve for 2W

\(2W = \frac{x}{2}\)

Solve for W

\(W = \frac{x}{4}\)

Recall that:

\(L = \frac{x}{2} - W\)

\(L = \frac{x}{2} - \frac{x}{4}\)

\(L = \frac{2x- x}{4}\)

\(L = \frac{x}{4}\)

So, the maximum area is:

\(A = L * W\)

\(A = \frac{x}{4}*\frac{x}{4}\)

\(Max\ Area = \frac{x^2}{16}\)

Answer:

The revenue from selling a pair of running shoes at p dollars per pair is 50,000p - p^2

Step-by-step explanation:

Here in this question, we are interested in writing an equation that represents the revenue from selling a number of shoes.

Mathematically;

Revenue = Number of shoes sold * Price of one shoe

From the question, the number of shoes sold at price P dollars is 50,000 - 40p

The price of a single pair is P dollars

So the revenue in this case will be ; p * (50,000 - 40p)

= (50,000p - 40p^2) dollars

The expression that represents the revenue in dollars is \((50000p-40p^{2} )\)

We have to find an expression  that represents the revenue in dollars

So that,

            Revenue = Number of shoes sold * Price of one shoe

It is given that the number of shoes sold at price P dollars is \((50000 - 40p)\)

and the price of a single pair is P dollars

Thus,  the revenue expression is,

                                \(= p * (50000 - 40p)\\\\=50000p-40p^{2}\)

The probability at least one of the ten songs has a BPM over 160 is approximately 0.2067.

To find the probability at least one of the ten songs has a BPM over 160, we first need to find the probability of a single song having a BPM over 160. We can do this using the normal distribution formula with a mean of 120 and standard deviation of 20:

P(BPM > 160) = 1 - P(BPM ≤ 160) = 1 - Φ((160-120)/20) = 1 - Φ(2) ≈ 0.0228

Next, we can use the binomial distribution formula to find the probability of at least one of the ten songs having a BPM over 160:

P(X ≥ 1) = 1 - P(X = 0) = 1 - (0.9772)^10 ≈ 0.2067

Answer:

(-4, 5)

Step-by-step explanation:

Hi there!
We are given the following system:
x+11y=51

3x+5y=13
And we want to solve it by substitution.
When we solve a system by substitution, we want to solve one of the equations for a variable; the variable should equal an expression containing the other variable. Then, we substitute that expression into the other equation as the variable we solve for, solve for that variable, and then use the value of the solve variable to find the value of the first variable

It's easier to solve for a variable if the leading coefficient in front of that variable is 1, like with x in the first equation (x+11y=51)
To solve this equation for x, we can subtract 11y from both sides.

x+11y=51

  -11y   -11y

_____________
x=51-11y
Now substitute 51-11y as x in 3x+5y=13:

3(51-11y)+5y=13

Multiply

153-33y+5y=13

Combine like terms.

153-28y=13

Subtract 153 from both sides

-28y=-140

Divide both sides by 28

y=5
Now substitute 5 as y in 51-11y to solve for x.

x=51-11y

x=51-11(5)
multiply

x=51-55

Subtract

x=-4

The answer is x=-4, y=5, or as a point, (-4, 5)

We can conclude that (5, -2, -3) is the vector that the linear 1-form acts on by taking a dot product.

To find the vector that the given linear 1-form acts on by taking a dot product, we need to express the linear 1-form in terms of a vector.

Let's start by writing the given linear 1-form in terms of differentials of the coordinate functions:

\(2dy-3 dz + 5 dx - 4 dy = 5 dx - 2 dy - 3 dz\)

We can recognize this expression as the dot product of a vector with components (5, -2, -3) with the differential of a general vector function (dx, dy, dz).

Therefore, the vector that the linear 1-form acts on by taking a dot product is simply (5, -2, -3).

To verify this, let's take the dot product of the given linear 1-form with the given vector V:

\((2 dy - 3 dz + 5 dx - 4 dy) * (it 3+ 4) = 5 dx * i + (-2 dy) * t + (-3 dz) * 1 = 5(1) + (-2)(3) + (-3)(4) = 5 - 6 - 12 = -13\)

Now let's take the dot product of the same vector with the vector (5, -2, -3):

\((it 3+ 4) * (5, -2, -3) = (3)(5) + (4)(-2) + (0)(-3) = 15 - 8 + 0 = 7\)

Since the dot product of the given linear 1-form with the vector V is equal to the dot product of the same vector with the vector (5, -2, -3), we can conclude that (5, -2, -3) is the vector that the linear 1-form acts on by taking a dot product.

Answer:

7 - 2m can be translated to "7 minus two times m" or "the difference between 7 and twice m".

3(m + 2) = 15 can be translated to "three times the sum of m and 2 is equal to 15" or "the product of 3 and the sum of m and 2 is 15".

To solve the equation, we can start by distributing the 3 on the left side:

3(m + 2) = 15

3m + 6 = 15

Then, we can subtract 6 from both sides:

3m + 6 - 6 = 15 - 6

3m = 9

Finally, we can divide both sides by 3:

3m/3 = 9/3

m = 3

Therefore, the solution to the equation 3(m + 2) = 15 is m = 3.

5m - m(2 - m) can be translated to "5m minus the product of m and the difference between 2 and m" or "the difference between 5m and m times the quantity 2 minus m".

To simplify the expression, we can use the distributive property to expand the second term:

5m - m(2 - m) = 5m - 2m + m^2 = m^2 + 3m

Therefore, the simplified expression is m^2 + 3m.

a. The Volume per month is required  = 46,000 units

b-1. The profit on a monthly volume of 61,000 is $3000

b-2. The Profit on a monthly volume of 87,000 units is $8,200

c. Volume is needed to obtain a profit of $16,000 per month is 126,000units

d. Volume is needed to provide a revenue of $23,000 per month is 25,556 units.

Proper production is pivotal in making the the business successful. There are many factors to consider to make sure that the production is at maximum efficiency. Example factors include the cost of materials, the quantity to produce, the selling price of the product, and the fixed and variable cost of the product.

a. There should be 46,000 units in order to break even.

The break-even formula is:

Break even = Fixed cost / Price - Variable cost

                   = 9,200/ 0.9 - 0.7

                   = 46,000

Volume per month = 46,000 units

b-1. The profit realized is $3,000 when monthly volume is 61,000 units.

The formula is:

Profit = Price × quantity - (fixed cost - variable cost × quantity)

Profit = 0.9 × 61,000 - (9,200 + 0.7 × 61,000)

Profit = 54,900 - 51,900

Profit = 3,000

b-2. The profit realized is $8,200 when monthly volume is 87,000 units.

Profit = 0.9 × 87,000 - (9,200 + 0.7 × 87,000)

Profit = 8,200

c. The monthly volume when profit is $16,000 is 126,000 units.

The formula is : Quantity = \(\frac{Profit+fixed cost}{Price-variable cost}\)

Quantity = \(\frac{16,000+9,200}{0.9-0.7}\)

Quantity = 126,000

d. The volume needed to provide a revenue of $23,000per month is 25,556 units.

Quantity = Revenue/ Price

Quantity = 23,000/ 0.9

a. The number of bricks required for the top step is 795.

b. The total number of bricks required for all the steps is 2250.

(a) To find the number of bricks required for the top step, we need to use the information that each successive step requires two less bricks than the prior step.

So, we can start by finding the total number of bricks required for all the steps and then subtracting the number of bricks required for the bottom 29 steps.

The total number of bricks required for all the steps can be found using the formula for the sum of an arithmetic sequence:

S = n/2 * (a1 + an)

where S is the sum, n is the number of terms, a1 is the first term, and an is the nth term.

In this case, we have:

n = 30 (since there are 30 steps)

a1 = 100 (since the bottom step requires 100 bricks)

d = -2 (since each successive step requires 2 less bricks than the prior step)

an = a1 + (n-1)d = 100 + (30-1)(-2) = 40.

Plugging these values into the formula, we get:

S = 30/2 * (100 + 40) = 2250

So, the total number of bricks required for all the steps is 2250.

To find the number of bricks required for the top step, we subtract the number of bricks required for the bottom 29 steps from the total number of bricks required for all the steps:

number of bricks required for top step = total number of bricks - number of bricks for bottom 29 steps

= 2250 - [100 + 98 + 96 + ... + 6 + 4 + 2]

= 2250 - 1455

= 795

Therefore, the number of bricks required for the top step is 795.

(b) To find the total number of bricks required to build the staircase, we simply add up the number of bricks required for each step. We can use the formula for the sum of an arithmetic series again to simplify the calculation:

S = n/2 * (a1 + an)

where S is the sum, n is the number of terms, a1 is the first term, and an is the nth term.

In this case, we have:

n = 30 (since there are 30 steps)

a1 = 100 (since the bottom step requires 100 bricks)

d = -2 (since each successive step requires 2 less bricks than the prior step)

an = a1 + (n-1)d = 100 + (30-1)(-2) = 40

Plugging these values into the formula, we get:

S = 30/2 * (100 + 40) = 2250

Therefore, the total number of bricks required to build the staircase is 2250.
