Answer:

A. 60 feet B. 7200 ft²

Step-by-step explanation:

A. Find the length of the corral along the river that will give the maximum area

To find the length of the corral that will give the maximum area, we differentiate A with respect to x and equate it to zero.

So, dA(x)/dx = d[x(240 - 2x)]/dx

= (240 - 2x)dx/dx + xd(240 -2x)/dx

= 240 - 2x -2x

= 240 - 4x

So, dA(x)/dx = 0

240 - 4x = 0

4x = 240

x = 240/4

x = 60 feet

B. Find the maximum area of the corral

The maximum area at x = 60 feet is

A(x)=x(240−2x)

A(60)=60(240−2(60))

A(60) = 60(240 - 120)

A(60) = 60(120)

A(60) = 7200 ft²

Answer:

maximum: 7200 sq ft.  60 ft along the river

Step-by-step explanation:

The maximum area of 7,200 square feet is reached when the corral has a length of 60 feet along the river.

Answer: You will have $24,551.84 when you turn 18.

Step-by-step explanation:

Formula for accumulated amount earned in t years:

[tex]A=P(1+\dfrac{r}{12})^{12t}[/tex], where P = principal value, r = rate of interest

Given: P= $10000, r = 5% t = 18 years.

Substitute all values in formula, we get

[tex]A=10000(1+\dfrac{0.05}{12})^{12\times18}\\\\=10000(1.004167)^{216}\\\\=10000(2.45518445623)\approx24551.84[/tex]

Hence,  you will have $24,551.84 when you turn 18.

The selling price of the skateboard is $84.

Answer:

y = 18

x = 7

Step-by-step explanation:

Since the Capulet's only have a total of 50 feet of fencing then that will also be the maximum perimeter of the fence and cannot exceed that value. Therefore, using the information provided we can conclude the following

y > 2x

y + y + x + x <= 50ft

2x + 2x + x + x <= 50ft

Now that we have these equations we can first solve for x and then solve for y

2x + 2x + x + x <= 50ft

6x <= 50ft   ... divide by 6

x <= 8.33

y > 2 * 8.33

y > 16.66

Therefore, one possible value would be

Total length of lizard is 3+6=9 inch

Step-by-step explanation:

Answer:

14.68

Step-by-step explanation:

4.32 + b = 19

Solve for b.

_____________

To solve, we need to get b by itself.

4.32 + b = 19

Subtract 4.32 from both sides :

b = 14.68

The numbers inside the parentheses are the x values. Replace x with each number and solve.

F(1) = 50 + 30(1)= 50+ 30 = 80

F(2) = 50 + 30(2)= 50 + 60 = 110

F(3) =!50 + 30(3)= 50 + 90 =140

The value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

The function is given below.

f(x) = 50 + 30x

The value of the function at x = 1, will be

f(1) = 50 + 30 × 1

f(1) = 50 + 30

f(1) = 80

The value of the function at x = 2, will be

f(2) = 50 + 30 × 2

f(2) = 50 + 60

f(2) = 110

The value of the function at x = 3, will be

f(3) = 50 + 30 × 3

f(3) = 50 + 90

f(3) = 140

Thus, the value of the function f(x) = 50 + 30x at x = 1, 2, and 3 will be 80, 110, and 140.

Step-by-step explanation:

Given

Identify a and b

The given equation is an exponential function and the general form is:

[tex]f(x) = ab^x[/tex]

When [tex]f(x) = ab^x[/tex] is compared to [tex]f(x) = 3(\frac{1}{5})^x[/tex]

We have that: [tex]a = 3[/tex] and [tex]b = \frac{1}{5}[/tex]

What do you mean by property?

I will guess for now, but if it is not right I will update it.

It would be the associative property since you are flipping the equation around.

Answer:

13, i think.

Step-by-step explanation:

use the equation: p( 1 - 7.5/100)^r

p= original amount

r = years

sub in numbers

22300 ( 1- 7.5/100)^r

just sub in different numbers for r till you get closest to your answer

After 13 years the value of the car would be $7700

"It describes the decrease in an amount by a consistent percentage rate over a period of time."

"f(t) = a(1 - r)^t , where t is time, a is the initial value and r is the rate"

For given example,

initial value of the car (a) = 22300

The value of the car depreciates at 7.5% per year.

So, the rate (r) = 7.5%

We can write 7.5 percent as,

7.5% = 7.5/100

        = 0.075

So, r = 0.075

Let 't' represents the number of years

We need to find the number of years when the car value is 7700 dollars.

y = $7700

Using the formula of exponential decay,

⇒ y(t) = a × (1 - r)^t

⇒ 7700 = 22300 × (1 - 0.075)^t

⇒ 0.3453 = (0.925)^t

⇒ t = 13.63

⇒ t ≈ 13

Therefore, after 13 years the value of the car would be $7700

Step-by-step explanation:

Use the Quadratic Formula to find the roots, i.e., the values of n for which 6n²-56n-40 = 0.

Answer:

2(n - 10)(3n + 2)

Step-by-step explanation:

Given

6n² - 56n - 40 ← factor out 2 from each term

= 2(3n² - 28n - 20) ← factor the quadratic

Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.

product = 3 × - 20 = - 60 and sum = - 28

The factors are - 30 and + 2

Use these factors to split the n- term

3n² - 30n + 2n - 20 ( factor the first/second and third/fourth terms )

= 3n(n - 10) + 2(n - 10) ← factor out (n - 10) from each term

= (n - 10)(3n + 2)

Thus

6n² - 56n - 40 = 2(n - 10)(3n + 2)
