A rectangle has sides measuring (12x - 2) units and (x + 8) units.

Part A: What is the expression that represents the area of the rectangle? Show your work. (5 points)

Part B: What is the expression that represents the perimeter of the rectangle? Show your work. (5 points)

Part C: What are the degree and classification of the expression obtained in Part A? (3 points)

Answers

Answer 1

The area equation is:

A = (12x - 2)*(x + 8)

Which is a polynomial of degree 2, and the perimeter is:

P = 26x + 12

How to write the area of the rectangle?

Remember that for a rectangle of length L and width W, the area is written as:

A = L*W

Here we know that:

L = (12x - 2)

W = (x + 8)

Then the equation for the area is:

A = (12x - 2)*(x + 8).

How to write the perimeter?

For a rectangle of length L and width W, the perimeter is:

P = 2*(L + W).

Replacing what we know, we get:

P = 2*(12x - 2 + x + 8) = 2*(13x + 6) = 26x + 12

What are the degree and classification of the area equation?

The area equation is:

A = (12x - 2)*(x + 8).

Notice that this is a polynomial that is made of the product of two polynomials of degree 1, so this is a polynomial of degree 2.

units3

Answers

Answer :

Volume is 471 unit^3

Step-by-step explanation :

Here we have been given with the radius and height of a cylinder that is 5 unit and 6 unit respectively. We need to calculate the volume of cylinder so we would be using its formula. V = πr^2h

Here,

h is heightr is radius

We have :

r = 5 h = 6

Substituting the values :

>> V = 3.14 × (5)^2 × 6

>> V = 3.14 × (5 × 5) × 6

>> V = 3.14 × 25 × 6

>> V = 3.14 × 150

>> V = 471

Volume of cylinder = 471 units .

Jeff Krause purchased 1,000 shares of a speculative stock in January for $1.89 per share. Six months later, he sold them for $9.26 per share. He uses an online broker that charges him $10.00 per trade. What was Jeff's annualized HPR on this investment?

Thanks!

Answers

Based on the price he purchased the stock and the amount he sold them for, Jeff's annualized HPR on the investment is 2,395%.

How much is Jeff's annualized HPR?

First find the net profit:

= (1,000 x 9.26) - (1,000 x 1.89) - 10

= $7,360

The HPR is:

= 7,360 / (1,000 x 1.89)

= 389.4%

The annualized HPR is:

= (1 + 389.4%)² - 1

= 2,395%

Note: Taken to the power of 2 because there are two six-month periods in a year.

Find sin 2x if cos x=-2/3 and x is in quadrant 2

Answers

Answer:

-4√5/9.

Step-by-step explanation:

if cos x = -2/3 then sin x = √(1 - (-2/3)^2)

= √(5/9)

= √5/3.

(As x is in quadrant 2 sin x is positive).

So:

sin2x = 2 sin x cos x

= 2 * √5/3 * -2/3

= -4/3 * √5/3

= -4√5/9.
