A triangle having area of √135 square meter and perimeter 18 meter has a side 4 meter. Find the measurement of remaining two sides.

Answers

Answer 1

The required measurement of the remaining two sides of the given triangle are 8 and 6 meters.

What is the Heron's formula?

Heron's formula is a formula for calculating the area of a triangle in terms of the lengths of its sides that is credited to Heron of Alexandria.

Given that, a triangle having area of √135 square meter and perimeter 18 meter has a side 4 meter.

Let other two sides be x and y,

Therefore,

x + y + 4 = 18

x + y = 14.....(i)

Now, according to Heron's formula,

Area of a triangle = √s(s - a)(s - b)(s - c) where s is half the perimeter, or (a + b + c) / 2.

Therefore,

√9(9 - 4)(9 - x)(9 - y) = √135

Squaring both sides

45(9-x)(9-y) = 135

(9-x)(9-y) = 3

81 -9y - 9x + xy = 3

9(x+y)-xy = 78

Put x+y = 14 from eq(i)

9×14-xy = 78

xy = 48

Now finding the factors of 48

48 = (6, 8), (12, 4), (24, 2), (16, 3), (48, 1)

If we consider (6, 8) this is satisfying eq(i)

6+8 = 14

Therefore, we can say the other two sides of the triangle are 8 and 6.

Hence, the required measurement of remaining two sides of the given triangle are 8 and 6 meters.

An open cylindrical water tank has base radius x metres and height h metres. Each square metre of the
base costs a dollars to manufacture and each square metre of the curved surface costs b dollars. The
combined cost of the base and curved surface is c dollars.
a Find c in terms of a, b, x and h.
b Show that the volume of the tank is given by V = 2(c − nax²).
-
c As x varies, prove that V is at its maximum when the cost of the base is dollars.

Answers

The combined cost of c dollars is a xπx² + 2πxhb. The volume of the tank will be V = πx²h. Maximum value of V is when c > 2a(2hb).

How to find cost of the base?

a. The cost of the base is given by a xπx², and the cost of the curved surface is given by 2πxhb. The combined cost of the base and curved surface is given by:

c = a xπx² + 2πxhb

b. To find the volume of the tank, we can use the formula for the volume of a cylinder:

V = πx²h

Substituting in the expression for c from part (a), we have:

V = πx²h = πx²(c - 2πxhb) / a

c. To find the maximum value of V, we can differentiate with respect to x and set the derivative equal to 0:

dV/dx = 2πx(c/a - 2hb) = 0

Solving for x, we get:

x = (c / 2a) / (2hb)

Since x is the radius of the tank, it must be positive, so we must have c > 2a(2hb) for the maximum value of V to exist.

if v in r3 and v·v = 0, then v is the zero vector. is it true or false? explain your answer.

Answers

It is true that if v in r3 and v·v = 0, then v is the zero vector.

If v is a vector in R3 (three-dimensional real space) and v·v = 0, then v is the zero vector.

The dot product of a vector with itself, v·v, is equal to the square of the magnitude of the vector, ||v||^2. If v·v = 0, it follows that ||v||^2 = 0, which means that the magnitude of v is 0. In other words, v has a length of 0.

The only vector in R3 with a length of 0 is the zero vector, which is represented by the vector (0, 0, 0). Thus, if v·v = 0, v must be the zero vector.

We have to find the cost of polishing the floor.

First we will calculate the area of floor of the square hall.

Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object or 2d figure. The measurement is done in square units, with the standard unit being square meters ([tex]m^{2}[/tex]).

The quadrilateral WXYZ is a square. The coordinates of the vertices W and X are (-3, 2) and (5, 3) respectively. Click to match each side of
the square with its slope.

Answers

Each side of the square should be matched with its slope as follows;

Side WX = 1/8.

Side YZ = -8.

How to determine whether the quadrilateral is a square by using slope?

In order for a quadrilateral to be a square, the two (2) pairs of its sides must be equal (congruent) and perpendicular to each other. Therefore, we would have to calculate the slope of each side by using this mathematical expression:

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Where:

x and y represents the data points or side lengths of a quadrilateral.

For side WX, the slope is given by:

Slope (m) = (3 - 2)/(5 - (-3))

Slope (m) = (3 - 2)/(5 + 3)

Slope (m) = 1/8.

In Mathematics, a condition that must be met for two (2) lines or side lengths to be perpendicular is given by:

Based on the table, which best predicts the end behavior of the graph of f(x)? Group of answer choices As x → ∞, f(x) → ∞, and as x → –∞, f(x) → ∞. As x → ∞, f(x) → ∞, and as x → –∞, f(x) → –∞. As x → ∞, f(x) → –∞, and as x → –∞, f(x) → ∞. As x → ∞, f(x) → –∞, and as x → –∞, f(x) → –∞.

Answers

The right answer is option B, which is "As x → ∞, f(x) → ∞, and as x → –∞, f(x) → –∞."

What is function?

A function from a set X to a set Y allocates precisely one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain. Originally, functions were the idealization of how a variable quantity depended on another quantity.

Here,

First, you must graph all of the supplied points in the table in order to establish the final behavior.

Remember that the behavior of f(x) as x approaches positive and negative infinity is the end behavior of a function.

According to the graph, as x approaches positive infinity, f(x) approaches negative infinity, and as x approaches negative infinity, f(x) approaches negative inifinity. In other words, f(x) always approaches negative infinity in any situation.

The correct answer is option B that is "As x → ∞, f(x) → ∞, and as x → –∞, f(x) → –∞."

(1 pt) Find the value(s) of a making v= 3ai+2j parallel to w=(a^2)i+6j

Answers

The vectors v and w must be parallel if the value of an is 3/a2.

The parts of each vector must be proportionate for v to be parallel to w.

v = 3ai + 2j

w = (a^2)i + 6j

Therefore,

3a / a^2 = 2 / 6

3a = (2/6)a^2

a = 3/a^2

The components of each vector must be proportionate in order to make two vectors parallel. In this situation, we wish to make v parallel to w because we have two vectors, v and w. We can use the following equations to express v and w:

v = 3ai + 2j

w = (a^2)i + 6j

We need to determine the ratio between the x-components (3a and (a2)) and the y-components (2 and 6), as we can see that they are not currently proportionate. To do this, we can construct a proportional equation where the ratio is 3a / a2 on one side and 2/6 on the other. This problem can be solved for a by simplifying the equation to 3a = (2/6)a2. This yields a value of 3 / a2, indicating that the value of a must be 3 / a2 for v and w to be parallel.

a car dealer wants to send out marketing materials in hartville, missouri. the marketing materials state that customers will pay the lowest sales taxes in wright county at her dealership. what is the sample?

Answers

The sample is a specific subset of the entire group of individuals being studied. In this case, the sample is the city of Hartville, Missouri.

Sampling is the process of choosing a subset of people (a statistical sample) from a statistical population in order to estimate characteristics of the entire population. It is used in statistics, quality control, and survey technique. Statisticians try to get samples that are typical of the population under consideration. In situations where it is impractical to assess the complete population, sampling offers insights and is more affordable and quicker than doing so.

To find patterns and trends in the broader data set being reviewed, data sampling is a statistical analysis approach that is used to choose, modify, and analyse a representative selection of data points. It lets data scientists, predictive modellers, and other data analysts to construct and execute analytical models more quickly while still generating correct results by working with a limited, manageable amount of data about a statistical population.
