Exponential growth is a pattern of data that shows a rapid increase over time, while exponential decay is a pattern of data that shows a rapid decrease over time.

An rise in the resultant quantity for a given quantity is referred to as exponential growth, and a decrease in the resultant quantity for a given quantity is referred to as exponential decay.

The fundamental distinction between the two is that in an exponential decay relationship, the output values rise quickly as the input value rises, whereas in an exponential growth relationship, the output rises noticeably faster as the input value rises.

a. 1 hour and 45 minutes for the bacteria population to double.

To find out how long it takes for the bacteria population to double, we need to solve the equation:

2p(0) = p(h)

where p(0) is the initial population and h is the time it takes for the population to double.

Since p(h) = [tex]1000e^{(0.4h)}[/tex], we can write:

2p(0) = [tex]1000e^{(0.4h)}[/tex]

Dividing both sides by 1000, we get:

2p(0)/1000 = [tex]e^{(0.4h)}[/tex]

Taking the natural logarithm of both sides, we get:

ln(2p(0)/1000) = 0.4h

Solving for h, we get:

h = ln(2p(0)/1000) / 0.4

We know that p(0) = 1, since the initial population is given as 1,000. Substituting this value, we get:

h = ln(2) / 0.4

h ≈ 1.73

So it takes approximately 1.73 hours for the bacteria population to double.

Rounding to the nearest quarter of an hour.

we get:

h ≈ 1.75 hours

Answer: A parabola can be defined as the set of all points that are equidistant from a focus and a directrix. Based on the information provided, the focus of the parabola is (0, 4) and the directrix is y =.

The parabola will open upwards or downwards depending on the location of the focus and the directrix. Since the focus is at (0, 4), and the directrix is at y =, the parabola must open upwards. The axis of symmetry of the parabola will pass through the focus and will be perpendicular to the directrix.

Without more information, it is not possible to fully determine the shape and equation of the parabola. The shape of the parabola and its equation can be found by using the focus and directrix and other information, such as the vertex or a point on the parabola.

Step-by-step explanation:

Answer:

Let a be the first term and d be the common difference.

3rd term = 1407

a+2d = 1407  ------- 1

10th term = 1183

a+9d = 1183  ------- 2

By solving 1 and 2, a = 1471 and d = -32

so the general term T(n) = 1471 + (n-1)(-32)

                                          = 1471 - 32n +32

                                          = -32n + 1503

Suppose the considered function whose graph is to be made is

f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values

f(x)

are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:

y = f(x)

Let the number of rows in the original arrangement be x. Then, the number of seats in each row in original arrangement = x

Total number of seats = x x x = x²

From the given information,

2x(x-10)= x²+ 300

2x²-20x = x²+300

x²-20x-3000

The relationship between two variables in which one is a constant multiple of the other is referred to as direct variation. For instance, two variables are said to be in proportion when one affects the other. b = ka is the equation if b is directly proportional to a. (where k is a constant).

Given that  d varies directly as t.

The relation between d and t is

d = kt.

Given that d = 180 when t = 3.

Putting d = 180 and t = 3 in d = kt

180 = 3k

Divide both sides by 3:

k = 180/3

k = 60

Putting k = 60  in d = kt:

d = 60t

Now putting d = 390 in d = 60t:

There will be 36.6 trees per acre after 4½ years from the end of the 5-year observation period. The solution has been obtained by using unitary method.

What is the unitary method?

The value of each individual unit is first determined using the unitary method, and only then is the value of the required number of units determined.

We are given that at the beginning of their observations, there was an average of 48 trees per acre. At the end of the 5-year period, there was an average of 42 trees per acre.

So, decline in trees per acre in 5 years is 48 - 42 = 6 trees per acre

So, decline in 1 year = 6/5 = 1.2 trees per acre

Similarly, decline in 4.5 years = 1.2 * 4.5 = 5.4 trees per acre

Thus, trees left per acre = 42 - 5.4 = 36.6 trees

Hence, there will be 36.6 trees per acre after 4½ years.

As per unitary method, you'll earn $9.50 by selling five magazine subscriptions.

The unitary method is a method of finding a single value of a quantity or unit, given the value of a unit of the same quantity. In this case, we need to find out how much money you'll earn by selling magazine subscriptions.

We know that for selling the first subscription, the magazine company will pay you $1.50. For each additional subscription sold, the magazine company will pay 20 cents more than what was paid for the previous subscription.

Let's use the unitary method to find out how much you'll earn by selling the second subscription.

The magazine company pays 20 cents more than $1.50 for the second subscription. Therefore, the payment for the second subscription is

=> $1.50 + $0.20 = $1.70.

Using the same method, we can calculate the payment for the third subscription, which is

=> $1.70 + $0.20 = $1.90.

Similarly, we can use the unitary method to calculate the payment for the fourth, fifth, and so on, subscriptions.

By adding up the payments for each subscription, we can calculate your total earnings. Let's assume you sold five subscriptions.

The payment for the first subscription is $1.50, for the second subscription, it's $1.70, for the third subscription, it's $1.90, for the fourth subscription, it's $2.10, and for the fifth subscription, it's $2.30.

Total earnings = $1.50 + $1.70 + $1.90 + $2.10 + $2.30 = $9.50.

Therefore, you'll earn $9.50 by selling five magazine subscriptions.

As per the density the probability that a density measurement of the post-1982 pennies is 0.3565 g/cm3.

Density is an important physical property that can help identify materials. In this case, we are interested in the density of zinc and how it relates to the post-1982 pennies.

To calculate the probability of a density measurement within 5% of the density of zinc, we need to first determine the range of densities that fall within 5% of the zinc density.

The 5% range of the zinc density is calculated by multiplying the zinc density (7.13 g/cm3) by 5% (0.05), which gives us 0.3565 g/cm3.

The upper and lower limits of this range are then calculated by adding and subtracting this value from the zinc density, respectively.

The upper limit is 7.4865 g/cm3 (7.13 + 0.3565),

while the lower limit is 6.7735 g/cm3 (7.13 - 0.3565).

This can be written as,

y = 25 + x ______(2)

Where y is the height of the tree.

Now,

From (1) and (2),

In a few months, the two trees will be the same height.

So,
