A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Six hundred feet of fencing is used. Find the dimensions of the playground that maximize the total enclosed area. What is the maximum area?

Answers

Answer 1

Answer:

the smallest dimension = 100 ft

the largest dimension = 150 ft

Maximum Area = 15000 ft²

Step-by-step explanation:

let x represent length of one side and L represent length of adjacent side

so from the question

3x + 2L = 600

2L = 600 - 3x

L = (600 - 3x)/2

L = (600/2) - (3x/2)

L  = 300 - (3x/2)

now Area of rectangle = L × x

Area = (300 - (3x/2)) × x

Area = 300x - 3x²/2

now we differentiate with respect to x  and equate to 0 in other to find critical point

dA/dx ⇒ 300x/x - 3x²/x = 0

300 - 3x = 0

3x = 300

x = 300/3

x = 100

so we input value of x into our previous equation

Area = 300x - 3x²/2

= 300(100) - (3(100)²)/2

= 30000 - 15000

Area = 15000

also we input value of x in L = 300 - (3x/2)

L  = 300 - (3(100))/2)

L = 300 - 150

L = 150

Therefore

the smallest dimension = 100 ft

the largest dimension = 150 ft

Maximum Area = 15000 ft²

Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out

Answers

Answer:

Darlene's net proceeds after the broker fees are taken out is $8,279.

Step-by-step explanation:

From the question, the following can be obtained:

Basic cost of purchase of the stock = $20,000

Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300

Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300

Selling price = $28,600

Broker fees related sales = 21

The net proceed can therefore be calculated as follows:

Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock  = $28,600 - $21 - $20,300 = $8,279

Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.

Point L is on line segment \overline{KM}

KM

. Given LM=3x+3,LM=3x+3, KM=5x+4,KM=5x+4, and KL=5x+1,KL=5x+1, determine the numerical length of \overline{KM}.

KM

.

Answers

Answer:

KM = 4 units

Step-by-step explanation:

Here, we are to determine the numerical length of KM

since point L is on the line segment;

Then;

KM = KL + LM

Thus;

5x + 4 = 5x + 1 + 3x + 3

5x + 4 = 8x + 4

8x - 5x = 4-4

3x = 0

x = 0/3 = 0

From the question;

KM = 5x + 4

Substitute x = 0

Thus we have;

5(0) + 4 = 4

KM = 4 units

Answers

Answer:

$1,539.70

Step-by-step explanation:

Given the data :

National average Teachers' salary (NATS)

YEAR:_1960 _ 1970 _ 1980 _ 1990 _ 2000 2010

NATS:4995_8626_15970_31367_41807_55202

AVEAGE SALARY INCREASE PER YEAR BETWEEN 1980 and 1990

Salary in 1980 = $15970

Salary in 1990 = $31367

Average salary increase per year:

Difference in salary / difference in years

$(31367 - 15970) / (1990 - 1980)

= $15397 / 10

= $1539.7

The discriminant is -23

The equation has 0 real solution

Step-by-step explanation:

The discriminant of the quadratic equation ax² + b x + c = 0 is Δ = b² - 4ac

If Δ > 0, then the equation has two different real solutionsIf Δ = 0, then the equation has one real solutionIf Δ < 0, then the equation has no real solutions

Let us use the rule above to solve the question

∵ x² - x + 6 = 0

a = 1, b = -1 and c = 6

∵ Δ = b² - 4ac

∴ Δ = (-1)² - 4(1)(6)

∴ Δ = 1 - 24

Δ = -23

The discriminant is -23

∵ -23 < 0

∴ Δ < 0

∴ The equation has no real solutions

The equation has 0 real solution

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the graph, the line is passing through two points (0, 10) and (5, 0)

m=0-10/5-0=-2

From the graph, the x intercept is at 5 on x axis.

Sam spending 5 hours on the internet and no time watching the television.
