If there is a plus sign, there is exponential growth happening by r fraction or r%.

If there is a minus sign, there is exponential decay happening by r fraction or r%.

If the population is currently 3,800 cockroaches.

The expression is given as

To write an exponential function in the form y = ab^x that goes through the points (0,11) and (2,396), we can use the fact that the exponential function is defined as y = ab^x, where a is the initial value and b is the growth factor.

First, we can find the growth factor by using the following equation: b = y2/y1.

In this case: b = 396/11 = 36

Next, we can use the point (0,11) and the growth factor to find the value of a.

Since we know that y = ab^x, we can substitute the point (0,11) and the growth factor into the equation:

11 = a(36)^0

a = 11

So, the exponential function that goes through the points (0,11) and (2,396) is: y = 11 * 36^x

It is important to note that the above function will pass through the points (0,11) and (2,396) but it may not pass through any other points. It is also a good practice to check the function by substituting the point (0,11) and (2,396) to confirm it gives the correct output.

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.Slope is-1/4.

When a line crosses the y-axis on a graph, that location is known as the y-intercept.It is always 0 for the associated x-coordinate.

By calculating rise over run, the slope can be determined.This is accomplished by splitting the discrepancies between the y- and x-coordinates. The values of the y-intercept and slope reveal details on the nature of the relationship between the two variables, x and y.

The slope is the change in Y over the change in x:

Slope = (0-1) / 4-0) = -1/4

Slope = -1/4

Y intercept is the Y value when x is equal to 0. In the point (0,1) x is 0 and y is 1, so the y-intercept is 1.

Annabeth's bi-weekly gross earnings, including overtime compensation, would be $1,097.56.

Amount is a term used to describe a quantity or size of something. It is used to refer to a number of objects, items, or people, as well as a measure of money, time, or distance. Amount is also used to describe the total sum of money that is owed, received, or spent.

This amount is calculated by multiplying her hourly rate of $21.84 (which is determined by dividing her bi-weekly gross earnings of $913.45 by 40 hours) by 47 hours, which is the total number of hours worked in the week. Then, her overtime compensation of 7 hours is multiplied by her hourly rate of $21.84 multiplied by 1.5, which is the rate for time-and-a-half.

Step-by-step explanation:

A line from first base to third base , divides the square into 2 right triangles.

using Pythagoras' identity on the top right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

here the hypotenuse (h) is the line connecting first base to third base and both legs of the triangle are 90 ft , then

h² = 90² + 90² = 8100 + 8100 = 16200 ( take square root of both sides )

The distance around the base of the cylinder is 5π m and the diameter of a base of the cylinder is 8 meters.

The total surface area of a cylinder is equal to the sum of the areas of all its faces. The total surface area with radius ‘r’, and height ‘h’ is equal to the sum of the curved area and circular areas of the cylinder.

Let's call the height of the cylinder "h". The surface area of a cylinder can be calculated as

Since the diameter of the base is 8 meters, the radius is 8/2 = 4 meters.

We know the surface area of the cylinder is 48π m², so we can use this information to find h:

⇒[tex]48 \pi = 2 \pi(4)h + 2 \pi(4)^{2}[/tex]

Expanding and simplifying the equation:

⇒48π = 8πh + 32π

Double integral is a type of integration which involves the integration of two variables. It is used to calculate the area or volume of a function of two variables. This type of integration is used to solve problems in areas such as physics, engineering, probability and statistics. Double integration can be used to calculate the center of mass of a two-dimensional object, or the moments of inertia of a two-dimensional object. In its most basic form, this type of integration involves the calculation of a limit where two variables are integrated with respect to each other.

To evaluate the double integral, one must use the formula for the area of a two-dimensional region: ∫∫f(x, y)dA = ∫∫f(x, y)dxdy. The limits of integration of the region D must also be taken into account. Thus, the double integral can be evaluated as follows:

The study of the sides, angles, and connections of the right-angle triangle is the main goal of the field of mathematics known as "trigonometry."

We are given that the angle on f depression between a bird and its prey is 70%.

This means that Theta = 70°

Also, the height of the bird from the ground is 18 feet.

Using trigonometry, we get
