Determine the number of possible solutions for a triangle with b = 37, a = 32, and b = 27.

Answers

Answer 1

There are two(2) possible solutions for the given parameters of a triangle. Using the law of cosines, the parameters of the triangle are calculated.

What is the law of cosines?

The law of cosines is used to relate the angles and side lengths of a triangle.

They are given as follows:

a² = b² + c² -2bc cos(A)

b² = a² + c² - 2ac cos(B)

c² = a² + b² - 2ab cos(C)

Calculation:

The given triangle has B = 37°, a = 32 and b = 27

So, using the law b² = a² + c² - 2ac cos(B)

On substituting,

27² = 32² + c² - 2(32)c cos(37°)

⇒ c² - 50.56 c + 1024 = 729

⇒ c² - 50.56 c + 295 = 0

Since the obtained equation is quadratic, it has 2 solutions.

Using quadratic formula the solutions are calculated.

c = [50.56 ± [tex]\sqrt{50.56^2-4(1)(295)}[/tex]]/2(1)

On simplifying,

c = 43.8 and c = 6.7

Therefore, there are 2 possible solutions for the given triangle.

See below for the demonstration of (e) graphing a line using x- and y-intercepts

The graphing method to demonstrate

To solve this question, we make demonstrate (e) graphing a line using x- and y-intercepts

The learning goals

At the end of this exercise, you should be able to graph a line using x- and y-intercepts

A brief overview

A linear equation is represented as:

Ax + By = C

Where:

y-intercept = C/Bx-intercept = C/A

This means that we plot the points (0,C/B) and (C/A, 0) on a graph and then connect the points using a straight line.

Once this is done, the line has been graphed.

For instance, a line parallel to 3x + 8y = 16 will have a slope of -3/8

An original problem to solve

Plot the graph of the following equation using the intercepts

2x + 4y = 10

We have:

2x + 4y = 10

Set x = 0 to determine the y-intercept

4y = 10

Divide by 4

y = 2.5

Set x = 0 to determine the x-intercept

2x = 10

Divide by 2

x = 5

So, we have:

(5, 0) and (0, 2.5)

Plot the above points and connect the points (see attachment for graph)

An original problem to solve by another student

Plot the graph of the following equation using the intercepts

3x + 6y = 18

We have:

3x + 6y = 18

Set x = 0 to determine the y-intercept

6y = 18

Divide by 6

y = 3

Set x = 0 to determine the x-intercept

3x = 18

Divide by 3

x = 6

So, we have:

(6, 0) and (0, 3)

Plot the above points and connect the points (see attachment for graph)

Answer:

Let's solve your equation step-by-step.

Step 1: Simplify both sides of the equation.

What is probability?

The chances of an event occurring are defined by probability. Probability has several uses in games, in business to create probability-based forecasts,

Given data;

Total no of students =  115

The total number of ways to elect a president = 115

If one person is elected as the president the total number of ways to elect a president  = 114

The different ways that the students can elect a president and a vice president are found as;

⇒ 115 ways × 114 ways

⇒ 13110 ways

Hence the different ways that the students can elect a president and a vice president will be 13110.

a lily pad is growing in a pond and it doubles in size every day. after 30 days it covers the entire pond. on what day does it cover half the pond?

Answers

The growth of the lily pad is in geometric progression, and it covers half the pond in 29 days.

In the question, we are given that the size of the lily pad doubles itself every day.

If we assume the size of the lily pad on the first day as a, then on the second day its size will be 2a, on the third day it will be 2(2a) = 4a, and on the fourth day, it will be 2(4a) = 8a, and so on.


This makes a geometric progression, with the first term as a, and the constant ratio as 2.

We are given that on the 30th day, the size of the lily pad, covers the entire pond.

The size on the 30th day can be shown as the 30th term of this geometric progression

Therefore, size of the  pond = a(2)³⁰⁻¹ = a.2²⁹. {Using the formula, aₙ = arⁿ⁻¹, where aₙ is the n-th term, a is the first term, and r is the constant ratio}.

We are asked the day on which the pond is half covered.

The size of the pond in this case = (a.2²⁹)/2 = a.2²⁸.

The day can be calculated as follows:

a.2ⁿ⁻¹ = a.2²⁸,

or, 2ⁿ/2 = 2²⁸,

or, 2ⁿ = 2²⁹,

or, n = 29.

Thus, the lily pad covers half the pond on the 29th day.

Write a rational expression that satisfies the following condition: non permissible values x=y, +-2

Answers

The rational expression that satisfies x = y +-2 is 2xy/(x + y)(x² - 4).

How to illustrate the expression?

It should be noted that non permissible value is the value of the variable which make the denominator of the rational expression equal to zero.

Based on the information, x + y gives x - y = 0.

x = 2 gives x - 2 = 0

x = -2 gives x + 2 = 0

Ths denominator according to the condition illustrated will be (x - y)(x - 2)(x + 2) = (x - y)(x² - 4)

Then, the rational expression can be written by taking the numerator and denominator. An example will be 2xy/(x + y)(x² - 4).

Determine two pairs of polar coordinates for (3,-3) when 0

Answers

The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).

What is a polar coordinate?

A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).

Next, we would determine the distance (r) and angle (θ) as follows:

r = √(3² + (-3)²)

r = √(9 + 9)

r = 3√2.

θ = tan⁻¹(-3/3)

θ = tan⁻¹(-1)

θ = 3π and 7π/4 (second and fourth quadrants).

Converting to degrees, we have:

θ = 135° and 315°.

x is 45° (45 degrees.)

To find this out, we first need to understand the properties of a rectangle. A rectangle has opposite sides that are equal, but more importantly, all 4 interior angles of a rectangle are right angles, meaning they are all 90 degrees. These can also be denoted by 4 square boxes in each corner.

When a rectangle is cut diagonally, the rectangle becomes two right triangles, but when joined together, of course make a rectangle. When they are cut diagonally, the triangles are congruent triangles by the Hypotenuse-Leg (HL) Congruence property.

To find the missing x in this angle, we must know that x is apart of a right angle, and if 45 is next to it, x must also be 45 degrees (90-45 = 45)
