Answer: When a polygon is transformed so that the image of A′ is at (−2, 4) and the image of D′ is at (−1, 2), it means that the image of the polygon is congruent to the original polygon and has undergone a transformation of a horizontal reflection.

A horizontal reflection is a transformation in which the shape is reflected over the x-axis, resulting in a mirror image of the shape with the same size and orientation but reflected horizontally. In this case, the image of the polygon is congruent to the original polygon and has undergone a horizontal reflection with a horizontal translation of 3 units to the left.

The transformation can be described as a composition of the horizontal reflection over the x-axis and a translation of -3 units horizontally.

A measure computed from the entire population is called a parameter. Option D is the correct answer.

A parameter is a numerical characteristic of the population, and it is usually estimated from a sample of the population. Parameters are usually unknown and are estimated using a variety of mathematical methods.

Examples of parameters include the population means, median, and standard deviation. Parameters can also be used to describe the characteristics of a population, such as the percentage of people who are a certain color, race, or gender.

Parameters are usually reported in summary form, such as the mean or median of a population. In contrast, a statistic is a measure computed from a sample and is not representative of the entire population. Statistics are used to make estimates and predictions about a population and are usually reported in the form of a confidence interval.

The exact value of the sine of angle R is equal to 1 / 2.

In this problem we find the representation of a right triangle, where two side lengths are known and the exact value of a trigonometric function must be found. First, determine the length of side PR:

PR = 72 cm - PQ

PR = 72 cm - 24 cm

PR = 48 cm

Second, determine the length of side PQ by Pythagorean theorem:

RQ = √[PR² - PQ²]

RQ = √[(48 cm)² - (24 cm)²]

RQ = 24√3 cm

Third, determine the exact value of a trigonometric function of angle R by definition of sine:

sin R = PQ / PR

sin R = (24 cm) / (48 cm)

sin R = 1 / 2

Fourth, determine the exact value of a trigonometric function of angle R by definition of cosine:

cos R = RQ / PR

cos R = (24√3 cm) / (48 cm)

The domain and range for the function for the maximum height of the rockets Kate fires is; h = 70·t - 16·t² are;

Domain; 0 ≤ t ≤ 4.375

Range; 0 ≤ h ≤ 39.06

A function is a rule that defines the relationship between input variables and output variables, such that the each value from the set of input variables are assigned to exactly on variable from the set of output variables.

The possible specified function in the question is; h = 70·t - 16·t², and the possible required details is the domain and range that best represent the situation.

The domain of the above function is the set of possible input (t) values, which is found by the time it takes the rocket to land after flight as follows;

At ground level, h = 0, therefore;

h = 70·t - 16·t² = 0

(70 - 16·t)·t = 0

A possible solution is therefore, t = 0

The other solution is found as follows;

(70 - 16·t) = 0

70 = 16·t

16·t = 70

t = 70/16 = 4.375

The other solution or time at which the rocket is at ground level is t = 4.375

The range is the set of possible h values, which is obtained as follows;

The maximum point of the quadratic function, f(x) = a·x² + b·x + c, is the point, x = -b/2·a. Therefore, comparison between the function, f(x) = a·x² + b·x + c, and h = 70·t - 16·t², we get;

a = -16

b = 70

c = 0

The maximum height reached, therefore is obtained at the point, at which; t = -70/(2 × (-16)) = 2.1875

The maximum height, [tex]h_{max}[/tex], is therefore;

[tex]h_{max}[/tex] = 70 × 2.1875 - 16 × 2.1875² =  76.5625

Answer:

The square root of 50 can be simplified to the radical form of 5*sqrt(2)

Step-by-step explanation:

To simplify the square root of 50, we factor the number 50, which is 50 = 510 = 552. The square root of any number that is a perfect square, such as 55, is equal to the number inside the square root, which is 5 in this case. The square root of any number that is not a perfect square, such as 2, remains under the radical sign.

Therefore, the simplified radical form of the square root of 50 is √50 = 5√2.

The square root of 50 in simplest radical form is 5√2.

To find the square root of 50 in simplest radical form, we need to determine if there are any perfect square factors in 50 that can be taken outside the square root symbol.

The prime factorization of 50 is 2 × 5².

We can see that 5² is a perfect square factor of 50.

Therefore, we can rewrite the square root of 50 as the square root of (2 × 5²).

Using the property of square roots, we can split the square root of a product into the product of the square roots of each factor:

√(2 × 5²) = √2 × √(5²)

The square root of 5² simplifies to 5, so we have:

√(2 × 5²) = √2 × 5

Therefore, the square root of 50 in simplest radical form is 5√2.

If the town has a population of 20000 and grows at 5% every year , then the time required for the population to reach 41600 is 15 years .

To find out how long it will take for the town's population to reach 41600, we can use the formula :

⇒ A = P(1 + r)ⁿ

Where:

A = final population of town , P = initial population o town

r = percent increase (as a decimal)

let n = number of years for population to reach 41600 .

We know the final population is 41600, the initial population is 20000, the percent increase is 5% = 0.05  and we have to solve for n.

Substituting the values ,

we get ;

⇒ 41600 = 20000(1 + 0.05)ⁿ  ;

⇒ 41600 = 20000(1.05)ⁿ  ;

⇒ 41600/20000 = (1.05)ⁿ  ;

taking "log" on both sides ,

we get ;

⇒ log(41600/20000) = n × log(1.05)  ;

⇒ n = log(41600/20000)/log(1.05)  ;

⇒ n = 15.0105 ≈ 15

Therefore ,  it will take approximately 15 years for the town's population to reach 41600, to the nearest tenth of a year.

An angle is a measure of the amount of rotation between two lines or planes. It is typically measured in degrees or radians. An angle can be formed by two rays that share a common endpoint, known as the vertex of the angle. The rays are called the sides of the angle, and the endpoint is called the vertex. Angles can be classified as acute, right, obtuse, or straight, depending on their measure.

Everyday objects contain some of the everyday examples of angles. Angles are formed by the shapes of objects like chairs, pizza, fingers, and scissors. The vertex point, a common vertex that connects the two lines that make up the angle sign, is present.

The increase in earnings brought on by producing one extra unit is known as the marginal profit. The proper domain for functions is the integers (0, 1, 2, ...).

By dividing marginal revenue by marginal cost, one can compute marginal profit. Because it can help determine whether to raise or lower the level of output, marginal profit analysis is useful.

Any quantity of output below the one at which marginal profit equals zero has a positive marginal profit, meaning that profit can be increased by producing more of that quantity. Conversely, any quantity of output above the one at which marginal profit equals zero has a negative marginal profit, meaning that profit can be increased by producing less of that quantity.

The function h(t) = (2t-3t^2)/(1+t^3) is continuous at a=1 because the limit of h(t) as t approaches 1 is equal to h(1).

First, we need to show that the limit of h(t) as t approaches 1 is equal to h(1).

Since h(t) = (2t-3t^2)/(1+t^3), we can rewrite the limit of h(t) as t approaches 1 as:

lim t->1 (2t-3t^2)/(1+t^3) = lim t->1 (2-3t)/(1+t^3)

We can now use the properties of limits to evaluate the limit.

Substituting t=1 into the expression for the limit, we have:

lim t->1 (2-3t)/(1+t^3) = (2-3(1))/(1+(1)^3) = -1/(2)

Now, we can use the definition of continuity to show that h(t) is continuous at a=1.

Since the limit of h(t) as t approaches 1 is equal to h(1), then h(t) is continuous at a=1.

Thus, we have successfully shown that the function h(t) = (2t-3t^2)/(1+t^3) is continuous at a=1.
