The population after 4 years will be 12,155.06. It will take approximately 22.52 years for the population to triple.

The population of a town grows proportionally to its current population. This means that the larger the population, the more it will grow. To determine the population after 4 years, we can use the formula:

P = P0 * (1 + r)^t

Where P is the final population, P0 is the initial population, r is the growth rate, and t is the time in years. Plugging in the values given in the question, we get:

P = 10,000 * (1 + 0.05)^4

P = 10,000 * 1.21550625

P = 12,155.06

Therefore, the population after 4 years will be 12,155.06.

To determine how long it will take the population to triple, we can use the same formula, but set P to 3 * P0 and solve for t:

3 * 10,000 = 10,000 * (1 + 0.05)^t

3 = (1 + 0.05)^t

ln(3) = t * ln(1.05)

t = ln(3) / ln(1.05)

t = 22.52

Therefore, it will take approximately 22.52 years for the population to triple.

Answer: It is not possible to use only translations and dilations to map one circle to another unless the two circles are identical in size and shape.

A translation is a transformation that moves an object without changing its size, shape, or orientation. It involves moving every point on the object the same distance in the same direction. Since a circle is defined by all the points that are equidistant from its center, a translation will simply move the entire circle in the same direction, but will not change its size or shape.

A dilation is a transformation that changes the size of an object, but not its shape or orientation. It involves multiplying the distance of every point on the object from a fixed center point by a scale factor. While a dilation can change the size of a circle, it will also change the distance between points on the circle, and thus change its shape.

Therefore, if the two circles are not identical in size and shape, it would be necessary to use other transformations, such as rotations or reflections, to map one circle to the other.

Step-by-step explanation:

The solution to the system of equations is (5.56, -4.73).

To solve the system of equations by the addition method, we need to follow these steps:

Step 1: Multiply one or both of the equations by a constant to make the coefficients of one of the variables the same in both equations.
Step 2: Add the two equations together to eliminate one of the variables.
Step 3: Solve for the remaining variable.
Step 4: Substitute the value of the variable back into one of the original equations to find the value of the other variable.

Let's apply these steps to the given system:

-2x - 7y = 22
7x - 4y = -20

Step 1: Multiply the first equation by 7 and the second equation by -2 to make the coefficients of x the same:

-14x - 49y = 154
-14x + 8y = 40

Step 2: Add the two equations together to eliminate x:

-41y = 194

Step 3: Solve for y:

y = 194/(-41)
y = -4.73

Step 4: Substitute the value of y back into one of the original equations to find the value of x:

-2x - 7(-4.73) = 22
-2x + 33.11 = 22
-2x = -11.11

Step-by-step explanation:

5'4 to 6'0 is 8

6'0 to 6'1 is 9

i think im right i dont use inches tho

The height difference between 5’4 and 6’1 is 9 inches.

Measurement is the method of comparing the properties of a quantity or object using a standard quantity.

Measurement is essential to determine the quantity of any object.

There are two heights given.

5’4 and 6’1.

5'4 means that 5 feet and 4 inches.

1 feet = 12 inches

5 feet = 60 inches

5'4 = 60 inches + 4 inches = 64 inches

Similarly,

6'1 = 6 feet + 1 inch

    = (6 × 12) inches + 1 inch

The measure of the two angles is x = 69 degrees and y = 70 degrees.

In every triangle, the total of the angles is 180 degrees. The Triangle Sum Theorem.

For triangle ABC it is given as follows:

Angle A + Angle B + Angle C = 180.

Let us suppose the measure of two angles as x and y.

According to the ratio we can write as follows:

x = 6k and y = 7k

The sum of the angles in a triangle is 180°, so we can write:

50° + 6k + 7k = 180°

13k + 50° = 180°

13k = 130°

k = 10°

Substituting the value of k in x and y we have:

x = 6k = 6(10°) = 60°

y = 7k = 7(10°) = 70°

Hence, the measure of the two angles is x = 69 degrees and y = 70 degrees.

The given statement in the problem (f/g)(-2) = -6/5 is true.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

f(x) = 3x²

g(x) x - 8 ; (f/g)(-2) = -6/5

Now,

To evaluate (f/g)(-2), we need to divide f(-2) by g(-2).

We have f(x) = 3x², so f(-2) = 3(-2)² = 12.

We also have g(x) = x - 8, so g(-2) = (-2) - 8 = -10.

(f/g)(-2) = f(-2) / g(-2) = 12 / (-10) = -6/5.

The surface area of the cylinder would be SA = 2π(1.6)² + 3.2π(3.8) square feet.

Option (A) is correct.

What is the surface area of the cylinder?

The surface area of a cylinder can be calculated using the following formula:

SA = 2πr² + 2πrh

where r is the radius of the circular base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi, approximately equal to 3.14159.

The surface area of a cylinder is the sum of the areas of its top and bottom circles, plus the area of its lateral surface (the curved surface that connects the two circles). The lateral surface area of a cylinder is found by multiplying the height of the cylinder by the circumference of one of its circular bases. Therefore, the correct method to calculate the surface area of the cylinder with diameter labeled 3.2 feet and height labeled 3.8 feet is:

SA = 2π(1.6)² + 3.2π(3.8)

So, the correct answer is:

SA = 2π(1.6)² + 3.2π(3.8) square feet

Hence, the surface area of the cylinder would be SA = 2π(1.6)² + 3.2π(3.8) square feet.

The area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

The area of a trapezoidal region is given by the formula A = 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height. This formula can be derived by dividing the trapezoid into two right triangles and a rectangle, and finding the area of each of these shapes.

First, let's consider the two right triangles. The height of each of these triangles is h, and the lengths of their bases are (a-b)/2 and (b-a)/2, respectively. The area of each of these triangles is therefore 1/2h(a-b)/2 = 1/4h(a-b).

Next, let's consider the rectangle. The length of this rectangle is b, and the height is h. The area of this rectangle is therefore bh.

The area of the trapezoidal region is the sum of the areas of the two right triangles and the rectangle. This gives us:

A = 1/4h(a-b) + 1/4h(b-a) + bh

Simplifying this equation gives us:

A = 1/2h(a+b)

Therefore, the area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

Angle theorems are rules that govern the properties of angles.

Now, we notice that one angle is a right angle and it is equal to 90°.

Also, we notice that all the angles meet at the same point.

So, we have that

x + 3x + 90° = 360° (sum of angles at a point)

Solving for x, we have that

x + 3x + 90° = 360°

4x + 90° = 360°

4x = 360° - 90°
