**Long multiplication is a method of multiplying two numbers which are difficult to multiply easily.**

**For example, we can easily find the product of 55 × 20 by multiplying 55 by 2 and then adding a 0 at the rightmost place of the answer.**

**55 × 2 = 110 and 55 × 20 = 1100.**

**But, many a time finding the product is not this easy. At such times we use the long method of multiplication.**

**Steps to multiply using Long Multiplication**

**Multiplying 2-Digit by 2-Digit Numbers**

**Let us multiply 47 by 63 using the long multiplication method.**

**1. Write the two numbers one below the other as per the places of their digits. Write the bigger number on top and a multiplication sign on the left. Draw a line below the numbers. **

Graph

y - 6 = 4 ( x - 4 )

### Answers

**Step-by-step explanation:**

First, we need to get it to slope-intercept form:

So you distribute the 4 to x-4:

4x-16

now the equation looks like this:

y-6=4x-16

now move the -6 to the other side:

y=4x-10

**Answer:**

The graph of the **equation **y - 6 = 4(x - 4) is attached at the end.

To graph the **equation **y - 6 = 4(x - 4), rewrite it in **slope**-**intercept **form by solving for y:

y - 6 = 4(x - 4)

y - 6 = 4x - 16

y = 4x - 16 + 6

y = 4x - 10

Now, the **slope **(m) is 4 and the y-**intercept **(b) is -10.

To graph the equation, plot a few points and draw a straight line passing through those points.

Choose some x-values and calculate the corresponding y-values:

For x = 0, y = 4(0) - 10 = -10

For x = 2, y = 4(2) - 10 = -2

For x = 4, y = 4(4) - 10 = 6

For x = 6, y = 4(6) - 10 = 14

The price-demand and cost functions for the production of microwaves are given as

p = 275 − x 60

p = 275 - x 60

and

C(x) = 50000 + 30x

where x is the number of microwaves that can be sold at a price of p dollars per unit and C(x) is the total cost (in dollars) of producing x

Required:

a. Find the profit function in terms of x.

b. Find the marginal cost as a function of x.

c. Find the revenue function in terms of x.

d. Find the marginal revenue function in terms of x.

### Answers

**Answer:**

ALTERNATIVE 1

a. Find the profit function in terms of x.

P(x) = R(x) - C(x)

P(x) = (-60x² + 275x) - (50000 + 30x)

P(x) = -60x² + 245x - 50000

b. Find the marginal cost as a function of x.

C(x) = 50000 + 30x

C'(x) = 0 + 30 = 30

c. Find the revenue function in terms of x.

R(x) = x · p

R(x) = x · (275 - 60x)

R(x) = -60x² + 275x

d. Find the marginal revenue function in terms of x.

R'(x) = (-60 · 2x) + 275

R'(x) = -120x + 275

The answers do not make a lot of sense, specially the profit and marginal revenue functions. I believe that the question was not copied correctly and the price function should be p = 275 - x/60

ALTERNATIVE 2

a. Find the profit function in terms of x.

P(x) = R(x) - C(x)

P(x) = (-x²/60 + 275x) - (50000 + 30x)

P(x) = -x²/60 + 245x - 50000

b. Find the marginal cost as a function of x.

C(x) = 50000 + 30x

C'(x) = 0 + 30 = 30

c. Find the revenue function in terms of x.

R(x) = x · p

R(x) = x · (275 - x/60)

R(x) = -x²/60 + 275x

d. Find the marginal revenue function in terms of x.

R(x) = -x²/60 + 275x

R'(x) = -x/30 + 275

So I'm evaluating a newspaper articles claims.

It says: offenses have increased threefold which is (three times).

The evidence shows that in 2000 the number was 935 and in 2018 the number 2448. Does this support or contradict the claim?

### Answers

**Answer: The data appears to support the claim.**

Explanation:

Ignore the year numbers.

Divide the two other values to get 2448/935 = 2.618

Round this to the nearest whole number to get 3

The data approximately supports the claim. It's not perfect, but it's fairly close.

Find the perimeter of quadrilateral ABCD with vertices A(-2,-2), B(-1,3),

C(5, 3), and D(4, -2).

### Answers

**Answer:**

22.2

**Step-by-step explanation:**

**Step one**

given the coordinates

ABCD with vertices A(-2,-2), B(-1,3), C(5, 3), and D(4, -2)

**AB=(-2,-2),(-1,3)**

**BC=(-1,3), (5, 3)**

**CD=(5, 3),(4, -2)**

**DA=(4, -2),(-2,-2)**

The distance between points AB=

[tex]AB= \sqrt (x_2-x_1)^2+(y_2-y_1)^2[/tex]

[tex]AB= \sqrt (-1+2)^2+(3+2)^2\\\\AB= \sqrt 1^2+(5)^2\\\\AB= \sqrt26\\\\AB=5.1[/tex]

The distance between points BC=

[tex]BC= \sqrt (5+1)^2+(3-3)^2\\\\BC= \sqrt 6^2+(0)^2\\\\BC= \sqrt36\\\\BC=6[/tex]

The distance between points CD

[tex]CD= \sqrt (4-5)^2+(-2-3)^2\\\\CD= \sqrt -1^2+(-5)^2\\\\CD= \sqrt26\\\\CD=5.1[/tex]

The distance between points DA

[tex]DA= \sqrt (4+2)^2+(-2+2)^2\\\\DA= \sqrt 6^2+(0)^2\\\\DA= \sqrt36\\\\DA=6[/tex]

Hence the perimeter = 5.1+6+5.1+6

If Triangle ABC is congruent to Triangle SRT, find the possible value(s) for x

### Answers

Answer:

x = 2 or x = -3

Step-by-step explanation:

Given that ∆ABC ≅ ∆SRT, it follows that their corresponding side lengths are congruent to each other.

Thus:

[tex] RT = BC [/tex]

[tex] (x^2 + x) = 6 [/tex]

Solve for x

[tex] x^2 + x = 6 [/tex]

Subtract 6 from each side

[tex] x^2 + x - 6 = 6 - 6 [/tex]

[tex] x^2 + x - 6 = 0 [/tex]

Factorise

[tex] x^2 + 3x - 2x - 6 = 0 [/tex]

[tex] x(x + 3) -2(x + 3) [/tex]

[tex] (x - 2)(x + 3) [/tex]

x = 2 or x = -3
