Using scientific notation, the area of the park, in m², is given by:

[tex]A = 8 \times 10^{10}[/tex]

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

When two numbers in scientific notation are multiplied, we have that:

Hence the area of the park is given by:

Answer:

13x^8 + 4x^5 - 16x^2 try this

Step-by-step explanation:

We can find the instantaneous rate of change at [tex]x=2[/tex] by evaluating the limit

[tex]\displaystyle \lim_{x\to2} \frac{f(x) - f(2)}{x - 2}[/tex]

(i.e. the definition of the derivative)

Since

[tex]f(x) = 2x^3 - 3x \implies f(2) = 10[/tex]

we have

[tex]\displaystyle \lim_{x\to2} \frac{f(x) - f(2)}{x - 2} = \lim_{x\to3} \frac{2x^3 - 3x - 10}{x - 2}[/tex]

Note that [tex]2x^3-3x-10=0[/tex] when [tex]x=2[/tex], which means [tex]x-2[/tex] divides the numerator exactly. By polynomial division, we can show

[tex]\dfrac{2x^3 - 3x - 10}{x - 2} = 2x^2 + 4x + 5[/tex]

Then in the limit, we can write

[tex]\displaystyle \lim_{x\to2} \frac{f(x) - f(2)}{x - 2} = \lim_{x\to2} \frac{(x-2) (2x^2 + 4x + 5)}{x - 2}[/tex]

As [tex]x\neq2[/tex], we can cancel the factors of [tex]x-2[/tex].

[tex]\displaystyle \lim_{x\to2} \frac{f(x) - f(2)}{x - 2} = \lim_{x\to2} (2x^2 + 4x + 5)[/tex]

The function in the remaining limit is continuous at [tex]x=2[/tex], so we can directly substitute [tex]x=2[/tex] to get its value,

[tex]\displaystyle \lim_{x\to2} \frac{f(x) - f(2)}{x - 2} = 2\cdot2^2 + 4\cdot2 + 5 = \boxed{21}[/tex]

Answer:

x < -2 and x > 2

Step-by-step explanation:

Given the inequality |3x| < -6

The function inside modulus can take both positive and negative value.

For the positive value;

3x < -6

x < -6/3

x < -2

For the negative value;

-3x < -6

-3x/-3 > -6/-3

x > 2

Hence the solution to the inequality is x < -2 and x > 2

Step-by-step explanation:

Sorry if I'm wrong

Ricky Bobby will have saved $875 in 15 weeks and he will have $1200 in 28 weeks.

Firstly solving first part of the question. Here, we need to calculate the savings in 15 weeks. To perform this calculation, we will keep the number of weeks in place of variable w.

Savings = 25×15 + 500

Performing multiplication

Savings = 375 + 500

Performing addition

Savings = $875

Now, solving the second part, which is finding the number of weeks. We will keep the savings amount at place of variable S.

1200 = 25w + 500

25w = 1200 - 500

Performing subtraction

25w = 700

w = 700 ÷ 25

Performing division

w = 28

Therefore, Ricky Bobby will have saved $875 in 15 weeks and he will have $1200 in 28 weeks.

Answer:

  domain: all real numbers except x=3 and x=5.

Step-by-step explanation:

You want the domain of a composition of rational functions f(x)=1/(x-2) and g(x)=4/(x-3).

The domain of a function is the set of values of the independent variable for which the function is defined.

To compute f(g(x)), you must first compute g(x). When x=3, the denominator of the function 4/(x-3) is zero, so the value is undefined. The domain must exclude x=3.

The composition is found by substituting g(x) for x in the definition of f(x).

  [tex]f(g(x)) = f(\dfrac{4}{x-3}) =\dfrac{1}{\dfrac{4}{x-3}-2}=\dfrac{x-3}{4-2(x-3)}\\\\f(g(x))=\dfrac{x-3}{4-2x+6}=\dfrac{x-3}{2(5-x)}[/tex]

We have written the composition in this form so you can see there is a denominator factor that will be zero when x=5. The domain of f(g(x)) must also exclude x=5.

The domain of f(g(x)) is all real numbers except x=3 and x=5.

Answer:

1. x = 7

Step-by-step explanation:

12x + 16 = 100

12x = 84

x = 7

Answer:

1. x = 7

2. Simon and Iris earned $212 selling candy.

Step-by-step explanation:

1. 12(7) + 16 = 100

  84 + 16 = 100

  100 = 100

  Therefore, x = 7.

2. If they split the price by 2, then we need to multiply $100 by 2.

100 x 2 = $200

   $200 + $12 = $212

 Therefore, Simon and Iris earned $212 selling candy.

The value of the variable 'x' will be 20. Then the third vertice of the triangle is (20, 4).

The vertices of the triangle are (x₁, y₁), (x₂, y₂), and (x₃, y₃).

Then the area of the triangle will be

Area = 1/2 |[(x₁y₂ + x₂y₃ + x₃y₁) - (y₁x₂ + y₂x₃ + y₃x₁)]|

The vertices of the triangle are given as,

(x₁, y₁) ⇒ (5, 2)

(x₂, y₂) ⇒ (x, 4)

(x₃, y₃) ⇒ (0, 3)

Then the area will be

Area = 1/2[{5 × 4 + x × 3 + 0 × 2} – {2 × x + 4 × 0 + 3 × 5}]

25/2 = 1/2 [20 + 3x – 2x – 15]

25 = [x + 5]

x = 25 – 5

x = 20

The value of the variable 'x' will be 20. Then the third vertice of the triangle is (20, 4).
