Therefore, the change in profit is approximately 0.60 and the percent change in profit is approximately 0.81%.

The given function is P = 100xe–x/400, where is sales.

The change in profit as sales increase from x = 115 to x = 120 units is to be determined.

To find the change in profit, we need to calculate the profit at x = 115 and x = 120 and then find the difference between them.

P(115) = 100 * 115e^(–115/400) ≈ 73.99

P(120) = 100 * 120e^(–120/400) ≈ 73.39

The change in profit = P(120) - P(115) ≈ 0.60

Approximate percent change in profit as sales increase from

x = 115 to x = 120 units = (change in profit / initial profit) × 100%≈ (0.60/73.99) × 100%≈ 0.81%.

The expression that is used to describe the given information is 6^(-6).

To discover the equal expression, we are able to simplify the fraction through the usage of the guideline of thumb for exponents that announces that once we divide  powers with the equal base, we are able to subtract the exponents.

An exponent refers back to the wide variety of instances various is elevated through itself.

Using this rule, we get:

(6^(-10)) / (6^4 * 6^0)

= 6^(-10) / 6^4 *1

= 6^(-10+4)

= 6^(-6)

So the equivalent expression is: 1/6^6 = 6^(-6)

As a result of answering the given question, we may state that As a result, the recursive formula for this geometric sequences is as follows: a1 = 2, a2 = 10, a3 = 50, and a4 = 250 a = 5 * an-1.

A sequence is an ordered list of elements in mathematics. Numbers, functions, and other mathematical objects can be used as elements. A series is frequently denoted by stating its terms in parenthesis, separated by commas. The series of natural numbers, for example, can be denoted as: (1, 2, 3, 4, 5, ...) Similarly, the series of even numbers is denoted as follows: (2, 4, 6, 8, 10, ...) Depending on whether it has a finite or infinite number of terms, a sequence might be finite or infinite.

We must first discover the common ratio, r, in order to find the explicit and recursive formulas for this geometric series.

To accomplish this, divide any phrase by its preceding term:

\(10 / 2 = 5\s50 / 10 = 5\s250 / 50 = 5\\\)

The common ratio r is 5, as we can see.

\(a = a1 * r^(n-1) (n-1)\\a = 2 * 5^(n-1) (n-1)\)

A geometric sequence's recursive formula is:

\(a = r * an-1\)

where a represents the nth phrase and an-1 represents the (n-1)th term.

The initial term a1 in this series is 2, and the common ratio r is 5. As a result, the recursive formula is:

\(a1 = 2\san = 5 * an-1\)

As a result, the recursive formula for this geometric series is as follows:

a1 = 2, a2 = 10, a3 = 50, and a4 = 250 a = 5 * an-1.

The sequence yn = √(n+1) - √n converges, and its limit can be found by simplifying the expression and applying the limit rules. The limit of yn as n approaches infinity is 0.

To find the limit of yn as n approaches infinity, we can simplify the expression. Let's start by rationalizing the numerator:

yn = (√(n+1) - √n) (√(n+1) + √n) / (√(n+1) + √n)

Simplifying the numerator, we get:

yn = [(n+1) - n] / (√(n+1) + √n)

= 1 / (√(n+1) + √n)

As n approaches infinity, both √(n+1) and √n also approach infinity. Therefore, the denominator (√(n+1) + √n) also approaches infinity. In the numerator, the constant 1 remains constant.

Using the limit rules, we can simplify the expression further:

lim(n→∞) yn = lim(n→∞) [1 / (√(n+1) + √n)]

= 1 / (∞ + ∞)

= 1 / ∞

The coordinates of the point that divides the line segment from (6, 2) to (8, -10) into a ratio of 1 to 3 are (7, -1).

To find the coordinates of the point on the directed line segment that partitions it into a ratio of 1 to 3, we can use the concept of section formula.

The section formula states that if we have two points A(x₁, y₁) and B(x₂, y₂) dividing a line segment in the ratio of m₁ : m₂, then the coordinates of the dividing point P are given by:

Px = (m₁ * x₂ + m₂ * x₁) / (m₁ + m₂)

Py = (m₁ * y₂ + m₂ * y₁) / (m₁ + m₂)

In this case, the ratio is 1:3, which means m₁ = 1 and m₂ = 3. The given points are A(6, 2) and B(8, -10). Substituting these values into the formula, we can calculate the coordinates of the dividing point P:

Px = (1 * 8 + 3 * 6) / (1 + 3) = 7

Py = (1 * -10 + 3 * 2) / (1 + 3) = -2/2 = -1

Therefore, the coordinates of the point that divides the line segment from (6, 2) to (8, -10) into a ratio of 1 to 3 are (7, -1).

To find the coordinates of the point that divides the line segment between (6, 2) and (8, -10) in a 1:3 ratio, we can use the section formula. Applying the formula, where m₁ is 1 and m₂ is 3, the point P(x, y) can be determined.

By substituting the values into the formula, the x-coordinate is calculated as (1 * 8 + 3 * 6) / (1 + 3) = 7, and the y-coordinate is (1 * -10 + 3 * 2) / (1 + 3) = -1. Thus, the coordinates of the point that partitions the line segment into a ratio of 1 to 3 are (7, -1).

Using quadratic function concepts, it is found that:

The height of the pumpkin after x seconds is modeled by:

\(y = -16x^2 + 95x + 10\)

Which is a quadratic equation with coefficients \(a = -16, b = 95, c = 10\).

The maximum height is the y-value of the vertex, given by:

\(y_{MAX} = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}\)

Hence:

\(\Delta = b^2 - 4ac = (95)^2 - 4(-16)(10) = 9665\)

\(y_{MAX} = -\frac{\Delta}{4a} = -\frac{9665}{4(-16)} = 151\)

The maximum height of the pumpkin is of 151 feet.

It hits the ground when \(y = 0\), hence:

\(x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-95 + \sqrt{9665}}{2(-16)} = -0.1\)

\(x_2 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{-95 - \sqrt{9665}}{2(-16)} = 6.04\)

Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage:

0.6000 * 100 = 60.00%

60

Step-by-step explanation:

If you take 45 percent of a number and get 27, then what is that number? In other words, you know that 45 percent of a number is 27 and you want to know what that initial number is.

To solve this problem you multiply 27 by 100 and then divide the total by 45 as follows: (27 x 100) / 45

The exact value of the given functions are as follows: sin(a - b) = -33/65, cos(a + b) = -16/65, tan(a - b) = 33/16.

To find the exact values of the given trigonometric functions, we will use the given information about sin(a) and cos(B) and apply the relevant trigonometric identities.

(a) sin(a - b):

We can use the trigonometric identity sin(a - b) = sin(a)cos(b) - cos(a)sin(b).

Given sin(a) = 3/5 and cos(B) = 5/13, we need to find cos(a) and sin(b) to evaluate sin(a - b).

To find cos(a), we can use the Pythagorean identity: cos^2(a) = 1 - sin^2(a).

Since a is in Quadrant I, sin(a) is positive, so cos(a) = sqrt(1 - (sin(a))^2) = sqrt(1 - (3/5)^2) = sqrt(1 - 9/25) = sqrt(16/25) = 4/5.

To find sin(b), we can use the Pythagorean identity: sin^2(b) = 1 - cos^2(b).

Since B is in Quadrant II, sin(b) is positive, so sin(b) = sqrt(1 - (cos(B))^2) = sqrt(1 - (5/13)^2) = sqrt(1 - 25/169) = sqrt(144/169) = 12/13.

Now we can substitute the values into the identity:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b) = (3/5)(5/13) - (4/5)(12/13) = 15/65 - 48/65 = -33/65.

Therefore, sin(a - b) = -33/65.

(b) cos(a + b):

We can use the trigonometric identity cos(a + b) = cos(a)cos(b) - sin(a)sin(b).

Using the values we found earlier:

cos(a + b) = (4/5)(5/13) - (3/5)(12/13) = 20/65 - 36/65 = -16/65.

Therefore, cos(a + b) = -16/65.

(c) tan(a - b):

We can use the trigonometric identity tan(a - b) = (sin(a - b))/(cos(a - b)).

Using the values we found earlier:

tan(a - b) = (sin(a - b))/(cos(a - b)) = (-33/65)/(-16/65) = (-33/65) * (-65/16) = 33/16.

Therefore, tan(a - b) = 33/16.

Answer:

52 tickets cost $10 and 18 tickets cost $12

Step-by-step explanation:

10x+12y=804. (1)

x+y=70. (2)

From (2)

x=70-y

Substitute x=70-y into (1)

10x+12y=804

10(70-y)+12y=804

700-10y+12y=804

700+2y=804

2y=804-700

2y=104

y=104/2

y=52

Recall

x+y=70

x+52=70

x=70-52

x=18

52 tickets cost $10 and 18 tickets cost $12

By solving a system of equations we will see that the correct option is A.

First, let's define the variables:

First, we know that 70 tickets were sold, so:

x + y = 70

And we know that they reached $804, then we have:

x*$10 + y*$12 = $804

Then our system is:

x + y = 70

x*$10 + y*$12 = $804

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate x on the first equation:

x = 70 - y

Now we can replace that in the other equation to get:

(70 - y)*$10 + y*$12 = $804

$700 - y*$10 + y*$12 = $804

$700 + y*$2 = $804

y*$2 = $804 - $700 = $104

y = $104/$2 = 52

So, 52 $12 tickets were sold, then the other 18 tickets were $12, so the correct option is A.
