Answer:

y=-2/3x+1

This is because (3--1/3--3) can be simplified to (-4/6) and simplified again to (-2/3) and then the y-intercept is 1.

the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].

To find the derivative of the function y = (ln(x + 4))x using logarithmic differentiation, we can follow these steps:

Step 1: Take the natural logarithm of both sides of the equation:

  ln(y) = ln((ln(x + 4))x)

Step 2: Use the logarithmic property ln(a^b) = b ln(a) to simplify the right-hand side of the equation:

  ln(y) = x ln(ln(x + 4))

Step 3: Differentiate both sides of the equation implicitly with respect to x:

  (1/y) * y' = ln(ln(x + 4)) + x * (1/ln(x + 4)) * (1/(x + 4))

Step 4: Simplify the expression on the right-hand side:

  y' = y * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]

Step 5: Substitute the original expression of y = (ln(x + 4))x back into the equation:

  y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))]

Therefore, the derivative of the function y = (ln(x + 4))x using logarithmic differentiation is given by y' = (ln(x + 4))x * [ln(ln(x + 4)) + (1/ln(x + 4)) * (1/(x + 4))].

Answer:

x₁(2x₁x₂² - x₂ - 3) - 3x₂

Step-by-step explanation:

The expression you provided is a polynomial in two variables, x₁ and x₂. Let's simplify it step by step:

2x₁²x₂² - x₁x₂ - 3x₁ - 3x₂

To simplify, we can look for common terms that can be factored out:

x₁(2x₁x₂² - x₂ - 3) - 3x₂

Now let's simplify the expression inside the parentheses:

2x₁x₂² - x₂ - 3

a and c are directly proportional to each other when a and b are directly proportional and b and c are directly proportional.

If a and b are directly proportional and b and c are directly proportional, it means that their ratios are equal. Direct proportionality implies that as one variable increases, the other also increases in proportion and as one variable decreases, the other also decreases in proportion.

Mathematically, this can be written as

a = kb and b = mc, where k and m are constants of proportionality.

Multiplying these two equations gives: a = kbm

Substituting the value of b from the second equation in the first equation, we get: a = kmc

Therefore, a and c are also directly proportional to each other with a constant of proportionality km.

Thus, if a increases by a certain factor, c will also increase by the same factor.

If a and b are directly proportional and b and c are directly proportional, then it can be concluded that a and c are directly proportional as well.

Let x be the number of peaches purchased and y be the number of mangos purchased.

We want to write a system of inequalities that represents the given conditions:

1. Olivia has $15 to spend, so the total cost of the peaches and mangos must be less than or equal to $15:

2x + y ≤ 15

2. Olivia must buy no less than 8 peaches and mangos altogether, so the total number of peaches and mangos purchased must be greater than or equal to 8:

x + y ≥ 8

To solve this system of inequalities graphically, we can plot the lines corresponding to each inequality on the same graph and shade the region that satisfies both inequalities. The solution will be any point in the shaded region.

To plot the line 2x + y = 15, we can find the intercepts:

So we can plot the points (0, 15) and (7.5, 0), and draw a line passing through them.

To plot the line x + y = 8, we can find the intercepts:

So we can plot the points (0, 8) and (8, 0), and draw a line passing through them.

The shaded region that satisfies both inequalities is the region below the line 2x + y = 15 and above the line x + y = 8.

Here is a graph of the two lines and the shaded region:

    |           /

15 |         /

     |       /  .

     |     /    |

     |   /      |

     | /        |

      |          |

      |          |

      |          |

  8  |----------+------

      0          8

The shaded region corresponds to the points that satisfy both inequalities, which include (2, 6), (3, 5), (4, 4), (5, 3), (6, 2), and (7, 1). Each of these points represents a possible combination of the number of peaches and mangos that Olivia can buy within her budget and the requirement to buy at least 8 peaches and mangos altogether.

Answer:

The airplane starts its descent from an altitude 500 feet higher.

Step-by-step explanation:

Given that:

F(x) = - 200x+20,000

g(x) = -200x+20,500

The functions are written in slope intercept format :

With a negative slope, the intercept gives the point which the rate of change begins in the vertical axis :

The slope is -200 ; which means that the descent rate of the airplane is 200

The intercept value however changes from 20,000 in f(x) to 20500 in g(x). This means that the height at which descent starts is now at a height of 20500 which is (20500 - 20000) = 500 miles higher than before.

Step-by-step explanation:

the expression to represent how much the basketball team will receive is:
$4.50S + $2.25C

To find the amount that the basketball team will receive from the car wash, we need to start by finding the total amount of money raised. We can do this by multiplying the number of SUVs by $10 and the number of cars by $5, and adding those two products together. So the total amount raised can be expressed as:

Total amount = $10S + $5C

Next, we need to determine what percentage of the total amount will go to the basketball team. We know that 25% goes to the football team, 30% goes to the soccer team, and the remaining percentage goes to the basketball team. We can express this as:

Basketball team's share = (100% - 25% - 30%) x Total amount

Simplifying this expression, we get:

Basketball team's share = 45% x Total amount

Substituting the expression for the total amount that we found earlier, we get:

Basketball team's share = 45% x ($10S + $5C)

Simplifying this expression further, we get:

Basketball team's share = $4.50S + $2.25C

So the expression to represent how much the basketball team will receive is:

$4.50S + $2.25C

Answer:

31.875 m

Step-by-step explanation:

We can begin solving the problem by using the formula for the volume of a cylinder and the volume of a cone.

The volume of the well is given by the formula for the volume of a cylinder:

V = πr^2h

where r is the radius of the well (half the diameter, which is 3/2 = 1.5 m) and h is the depth of the well (21 m).

V = π(1.5)^2(21) = 42.5π m^3

The embankment is formed by the earth that was dug out of the well, and it has the shape of a cone. The volume of the cone is given by the formula:

V = 1/3 πr^2h

where r is the radius of the base of the cone (4 m) and h is the height of the embankment.

V = 1/3π(4)^2h = 4/3πh m^3

Now we know that the volume of the embankment is equal to the volume of the well:

V = 42.5π m^3 = 4/3πh m^3

Then we can solve for h by dividing both sides by 4/3π:

h = 42.5π m^3 * 3/4π = 31.875 m

So the height of the embankment is 31.875 m.

The required number corn plants are on the farm are 21.

metre stick counting techniques. Count the seedlings for each metre of the row using a metre stick. To calculate plants per square metre, multiply that amount by 100, then divide it by the seed spacing in centimeters.

Let the number of rows be x.

the number of corn plants = x - 4

So,

x(x - 4) = 525

x^2 - 4x - 525 = 0

On solving the above quadratic equation, we get

x = 25, x = -21

Thus, number of corn plants in the row are 52 - 4 = 21

In this triangle, the product of tan A and tan C is `(BC)^2/(AB)^2`.

The given triangle ABC has angle A measuring 45 degrees, angle B measuring 90 degrees, and angle C measuring 45 degrees , Answer: `(BC)^2/(AB)^2`.

We have to find the product of tan A and tan C.

In triangle ABC, tan A and tan C are equal as the opposite and adjacent sides of angles A and C are the same.

So, we have, tan A = tan C

Therefore, the product of tan A and tan C will be equal to (tan A)^2 or (tan C)^2.

Using the formula of tan: tan A = opposite/adjacent=BC/A Band, tan C = opposite/adjacent=AB/BC.

Thus, tan A = BC/AB tan C = AB/BC Taking the ratio of these two equations, we have: tan A/tan C = BC/AB ÷ AB/BC Tan A * tan C = BC^2/AB^2So, the product of tan A and tan C is equal to `(BC)^2/(AB)^2`.
