A certain forest covers an area of 2500km Suppose that each year this area decreases by 6.25% What will the area be after 15 years Use the calculator provided and round your answer to the nearest square kilometer.

Luca picks his number first. then, craig picks a number from the remaining cards, these two events are Dependent.

Total number of cars are 25,

Luca picks randomly a card so probability is now 1/25 and total number of cars are now 24.

If craig have to pick then the probability of it becomes 1/24 as one card was already picked by the Luca,

So this indicated that these two events are Dependent.

In probability, dependent events are those whose occurrence influences the likelihood of occurrence of another event. Imagine there are 3 red and 6 green balls in a bag. One after the other, two balls are taken out of the bag.

Let A represent the first draw's red ball draw and B represent the second draw's green ball draw. If the first draw's ball is not put back in the bag, then A and B are dependent events because P(B) changes depending on whether the first draw's ball was red or green.

The equation of the line to commute the time is written as y = -1/2x + 24.5.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The given points are (1,24) and (15,17). To write the equation of the line first calculate the slope of the line and then find the y-intercept of the line.

Slope =  ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 17 - 24 ) / ( 15 - 1 )

Slope = -7 / 14

Slope = -1 / 2

The y-intercept is:-

y = mx + c

24 = -1/2 + c

c = ( 48 + 1 ) / 2

c = 49 / 2

c = 24.5

The equation of the line can be written as:-

y = mx + c

y = -1/2x + 24.5

#SPJ1

Step-by-step explanation:

A line that is parallel to another line has the same slope but a different y-intercept. The slope of the line through the points (1,-2) and (-6,3) can be found using the slope-point formula:

slope = (y2 - y1) / (x2 - x1) = (3 - (-2)) / (-6 - 1) = 5/7

So, a line that is parallel to this line would have the same slope of 5/7. To find an equation for a line with this slope that passes through a different point, we can use the point-slope formula:

y - y1 = m * (x - x1)

Where m is the slope and (x1, y1) is a point on the line. We can choose any point to use in this formula, but a common choice is the origin (0,0). So, plugging in the values we have:

y - 0 = 5/7 * (x - 0)

y = 5/7 * x

This is the equation for a line that is parallel to the line through the points (1,-2) and (-6,3) and passes through the origin.

Answer: The lateral surface area of the cylinder can be found using the formula: πr h, where r is the radius and h is the height of the cylinder.

Given that the height of the cylinder is 22 ft, and the diameter is 6 ft, the radius can be found by dividing the diameter by 2: r = 6 / 2 = 3 ft.

So the lateral surface area of the cylinder is: πr h = π * 3 * 22 = 66 * π ≈ 208.36 sq ft.

Rounding to the nearest hundredth, the lateral surface area of the cylinder is 208.36 sq ft.

Andy should write $507.18 for the balance on January 30. The solution has been obtained by using arithmetic operations.

What are arithmetic operations?

Four fundamental mathematical operations can be used to express any real number.

1. To determine the total of the numbers, use the addition operator ('+').

2. Use the sign "-" when subtracting to find the differences between the numbers.

3. Multiply when the result is the product of the numbers.

4. Dividing the numbers produces their quotient.

We are given that the amount balance on January 24 is $104.47 and she deposited $407.71 on January 30.

So, the amount Andy should write for the balance on January 30 is

⇒$104.47 + $407.71

⇒$507.18

Hence, Andy should write $507.18 for the balance on January 30.

The total population, h(x): of bison in the two regions 0f the park X years after 2010 is h(x) = 1050(1.14)ˣ. So the option a is correct.

The following functions represent the population of bison in two regions of a wildlife park; where X is the number of years since 2010.

f(x) = 600(1.14)ˣ

g(x) = 450(1.14)ˣ

We must tell the function that represents the total population of bison in the two park regions x years after 2010.

h(x) = Total Population

So, h(x) = f(x) + g(x)

Now put the value of f(x) and g(x)

h(x) = 600(1.14)ˣ + 450(1.14)ˣ

The solution of the piecewise function at the given values of the independent variable g(0) is 5, g(-7) is 12 and g(2) is 7.

This is an example of a piecewise function, which is a function composed of two or more parts, each part being defined by a separate equation.

In this function, the first part is defined as g(x) = x+5 if x >= -5, and the second part is defined as g(x) = -(x+5) if x < -5.

To evaluate the function at the given values of the independent variable, we can simply substitute the values into the appropriate equation.

At x = 0,

=> g(0) = 0+5 = 5.

At x = -7,

=> g(-7) = -(-7+5) = 12.

And at x = 2,

In the given figure, AB || CD. Find the measure of x, y and z.

The total Messages that Tammy, Felipe, and David sent are 30, 50, and 45 messages respectively.

Let's denote the number of text messages sent by Tammy as x, Felipe as y, and David as z. Based on the information given, we have:

y < x and z = 3y.

The total number of messages they sent is x + y + z = x + y + 3y = 4y + x.

Since the total number of messages sent is not specified, we can choose an arbitrary value for the total number of messages. Let's choose 90 messages. Then, we have:

4y + x = 90

x = 90 - 4y.

Substituting z = 3y into x = 90 - 4y, we get:

3y = 90 - 4y

7y = 90

y = 90/7 = 15.

Plugging y = 15 into x = 90 - 4y, we get:

x = 90 - 4 * 15 = 30.

Therefore, Tammy sent 30 messages, Felipe sent 15 messages, and David sent 45 messages.

An arrow pointing in the direction of a vector's magnitude and a line representing the vector's direction can be used to depict a vector.

41 + 5/7 * (-1/2) = 41 - 5/14
41 - 5/14 = 40.6428571429

So the answer is 40.6428571429.

The missing angles in the figure are:

∠XVR = 125°

∠RVS = 55°

∠WVS = 125°

∠RST = 110°

∠RSV = 70°

∠VSU = 110°

∠UST = 70°

∠TUS = 39°

Angle geometry is a branch of mathematics that deals with the study of angles and their properties in two-dimensional figures such as circles, triangles, and polygons.

∠XVW + ∠XVR = 180° (sum of angles on a straight line is 180° )

Thus, ∠XVR = 180 - 55 = 125°

∠RVS = 55° (vertically opposite angles are equal)

∠WVS = 125° (vertically opposite angles are equal)

∠RST =  55 + 55 = 110°  (exterior angle of a triangle)

∠RSV = 180-55-55 = 70° (sum of angles in a triangle is 180°)

∠VSU = 110° (vertically opposite angles are equal)

Both graphs show the same relationship between Clem's waist height and time, but the exponential graph shows a more rapid increase in Clem's waist height over time.

Both graphs depict the relationship between Clem's waist height and time. The first graph is linear and is represented by the equation y = 2x + 3, where y is Clem's waist height and x is the amount of time that has passed. The second graph is exponential and is represented by the equation y = 2^x + 3. Both graphs show that Clem's waist height increases with time – the difference is that the linear graph shows a steady, linear increase, while the exponential graph shows an exponential increase. For example, if Clem's waist height was 3 inches at the start, then after 1 hour it would be 5 inches on the linear graph, but 8 inches on the exponential graph. This difference can be seen in the calculations: 1 hour on the linear graph would be 3 + (2 x 1) = 5 inches, while 1 hour on the exponential graph would be 3 + (2^1) = 8 inches.

In summary, both graphs show the same relationship between Clem's waist height and time, but the both graphs show the same relationship between Clem's waist height and time, but the exponential graph shows a more rapid increase in Clem's waist height over time.

A function is described as a relation among a fixed of inputs having one output every. In easy words, a feature is dating among inputs in which every entry is associated with precisely one output.

Given, The function f(x) = 20x + 80 represents the distance in miles a drone flew.

The function g(x) = x + 2 represents the time the drone flew in hours

Part A:

f(x) = 20x + 80

F(2) = 20*2 + 80

F(2) = 120

g(x) = x + 2

g(2) = 2 + 2

g(2) = 4

Part B: f(x) divided by g(2)

=> f(x) / g(2)

=> (20x + 80 ) /4

=> 5x + 20 (since, g(2) is 4)

Part C:  the domain of f divided by g of x

So,

f(x) / g(x ) = (20x + 80)/(x +2)

=>  (20x + 80)/(x +2)
