The cost for the lunches will be:

1 lunch = $2.50

2 lunches = $5

3 lunches = $7.50

4 lunches = $10

From the information, the cost of a school lunch is $2.50. Therefore, the cost of 1 lunch will be:

= 1 × $2.50

= $2.50

The cost of 2 lunches will be:

= 2 × $2.50

= $5.00

The cost of 3 lunches will be:

= 3 × $2.50

= $7.50

Answer:

6.8 miles

Step-by-step explanation:

First, create the equation representing Chelsey's miles compared to Kyle's:

c = k + 2.8

Next, find how many miles Chelsey runs if Kyle runs 4 miles.

Plug in 4 as k into the equation:

c = k + 2.8

c = 4 + 2.8

c = 6.8

So, Chelsey runs 6.8 miles

Answer:

Each day after school, Chelsey runs 2.8 miles farther than Kyle.

Part A. Write an equation that represents the number of miles Chelsey runs, c, compared with Kyle, k.

Limit of the function ln(n³)/10n is \(\lim_{n \to \infty}\) (3/n) and the sequence will be divergence in nature.

In Arithmetic, divergence and curl are the two fundamental procedure on the vector field. Both are significant in math as it assists with fostering the higher-layered of the central hypothesis of analytics. For the most part, uniqueness makes sense of how the field acts towards or away from a point. Likewise, curl is utilized to quantify the rotational degree of the field about a specific point.

We have a\(_n\)=ln(n³)/10n

Apply n'th term test for divergence, which states that,

If \(\lim_{n \to \infty} a_n\) !=0 , then ∑a\(_n\) diverges

Apply L'Hospital's rule,then \(\lim_{n \to \infty} ln(n^3)/10n\), Test L'Hospital condition:0/0

=\(\lim_{n \to \infty}\) d [ln(n³)/10n] / dn

=\(\lim_{n \to \infty}\)  (1/n³) ×3n²(since differentiation of ln(x) is 1/x)

=\(\lim_{n \to \infty}\)(3/n)

If n tends to infinite then the function tends to zero because 1/n tends to zero.

But,By the limit chain rule we know that 1!=0.So,according to the postulate of the divergence test criteria,we got that  the given function will diverges.

The table that shows a constant rate of change of -3 is Table D.

Option D is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The constant rate of change (r):

Take two ordered pairs (a, b) and (c, d)

= (d - b) / (c - a)

Now,

From Table D.

We see that,

r = (-1 - 2) / (-21 + 22) = -3/1 = -3

r = (-4 + 1) / (-20 + 21) = -3/1 = -3

The inequality could be used to find the greatest number of people, p, that can attend is  3.5p + 5p ≤ 300.

Here the inequality is that the sum of the cost of rentals and food which is represented by 3.5p and 5p, respectively, must be less than or equal to $300. By solving the inequality we can determine the maximum number of people that can attend the party while staying within Xian's budget.

To solve the inequality, we first subtract 5p from both sides to isolate the 3.5p term. This results in 3.5p≤300-5p. Then we divide both sides by 3.5 to isolate p, which yields p≤85.71. Since we can't have a fractional number of people, we can determine the maximum number of 85  people that can attend the party.

Answer:

\(3 + \frac{1}{2\sqrt{3} } + \frac{1}{5\sqrt[5]{81} }\)

Step-by-step explanation:

Just to make it easier to see, \(\sqrt{x} = x^{\frac{1}{2} }\) and \(\sqrt[5]{x} = x^{\frac{1}{5} }\)  This way we could more easily use the power rule of derivatives.

So if f(x) = \(x^{2} +x^{\frac{1}{2} } +x^{\frac{1}{5} }\) then f'(x) will be as follows.

f'(x) = \(x^{1} +\frac{1}{2} x^{-\frac{1}{2} } +\frac{1}{5} x^{-\frac{4}{5} } = x +\frac{1}{2x^{\frac{1}{2} }} +\frac{1}{ 5x^{\frac{4}{5} }} = x +\frac{1}{2\sqrt{x}} +\frac{1}{ 5\sqrt[5]{x^4} }\)

to find f'(3) just plug 3 into f'(x) so \(3 + \frac{1}{2\sqrt{3} } + \frac{1}{5\sqrt[5]{81} }\)

Therefore, if the insurance provider reimburses damages on a real cash-value basis, the most the insurer could possibly pay Cornell for the destroyed personal goods is $21,333.33.

The fraction or proportion can be expressed as a percentage as a number out of 100. Latin's translation of the term "percent" is "per hundred". The part (numerical number) is divided by the total (numerical value) to determine the percentage, which is then multiplied by 100.

If Ivy's losses are covered on a true cash-value basis, her insurer would be required to pay the following maximum amount:

The depreciated worth of the destroyed personal property must be determined first. Given that the expected 15-year useful life and the average age of the product

Given that its expected usable life is 15 years and that its average age is 5 years, the amount of its usefulness that has already been used up is:

5 years / a fifteen-year period equals a third, or 33.33%

As a result, the depreciated worth of the personal property damaged is:

$32,000 x (100% - 33.33%) = $21,333.33

Therefore, if the insurance provider reimburses damages on a genuine cash-value basis, the most the insurer could possibly pay Harvard for the destroyed personal goods is $21,333.33. This is due to the insurance provider's refusal to pay Ivy the full cost of replacement of what was damaged, but only the diminished worth of it.

The maximum amount the insurance company would pay Ivy on an actual cash-value basis is $21,338.68.

what is percentage?

Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".

To determine the maximum amount the insurance company would pay Ivy on an actual cash-value basis, we need to calculate the depreciated value of the damaged personal property.

First, we can calculate the percentage of the useful life that the damaged personal property had been used up to the time of the fire:

Percentage of useful life used = (age of damaged property / useful life) x 100%

Percentage of useful life used = (5 / 15) x 100%

Percentage of useful life used = 33.33%

Next, we can calculate the depreciation percentage based on the percentage of useful life used:

Depreciation percentage = Percentage of useful life used x 1/100

Depreciation percentage = 33.33% x 1/100

Depreciation percentage = 0.3333

Finally, we can calculate the depreciated value of the damaged personal property:

Depreciated value = Replacement price x (1 - Depreciation percentage)

Depreciated value = $32,000 x (1 - 0.3333)

Depreciated value = $21,338.68

Therefore, the maximum amount the insurance company would pay Ivy on an actual cash-value basis is $21,338.68.

Step-by-step explanation:

it seems you solved the tricky part yourself already.

just to be sure, let's do the first derivative here again.

the easiest way would be for me to simply multiply the functional expression out and then do a simple derivative action ...

f(t) = (t² + 6t + 7)(3t² + 3) = 3t⁴ + 3t² + 18t³ + 18t + 21t² + 21 =

f'(t) = 12t³ + 54t² + 48t + 18

and now comes the simple part (what was your problem here, don't you know how functions work ? then you are in a completely wrong class doing derivatives; for that you need to understand what functions are, and how they work). we calculate the function result of f'(2).

we simply put the input number (2) at every place of the input variable (t).
