Triangle ABC has perimeter 22 cm.
AB = 8 CM
BC = 5cm

By calculation, deduce whether triangle ABC is a right-angled triangle.

Answers

Answer 1

Answer:

Triangle ABC is not a Right Triangle

Step-by-step explanation:

The perimeter of a triangle is all of the sides added together so we can model our equation like so:

AB + BC + CA = P

or

8 + 5 + CA = 22

We first combine like terms

13 + CA = 22

Then make the variable have no numbers on its side

13 + CA = 22

-13          -13

CA = 9

So now that we know what CA is, we can determine whether or not its a right triangle

We can use the Pythagorean Theorem for this:

a^2 + b^2 = c^2   (the '^' symbol means 'to the power of')

or

5^2 + 8^2 = 9^2

Now we Solve

5^2 = 25

8^2 = 64

9^2 = 81

25 + 64 =? 81

89 does not equal 81

So Triangle ABC is not a Right Triangle

Which equation matches the graph of the greatest integer function given
below?

A. y = [x]-2
B. y = [x] +2
C. y -[x]+3
D. y = [x]-3

Answers

The equation that matches the graph of the greatest integer function is y = [x] - 2

How to determine the equation?

The parent function of an step function is represented as:

y = [x]

From the given graph, we can see that the lines are shifted 2 units down.

This means that:

(x,y) = (x,y - 2)

So, we have:

y = [x] - 2

Hence, the equation that matches the graph of the greatest integer function is y = [x] - 2

A.
-5x = -23

B.
5x = 17

C.
-5x = 2

D.
5x = -12

Answers

Answer:

A.  -5x = -23

Step-by-step explanation:

First you have to simplify the equation - 4(x - 5) + 8x = 9x - 3

-4x + 20 + 8x = 9x -3

9x - 4x = 20 + 3

5x = 23

=> equivalent to answer A.

The equivalent expression is,

⇒ - 5x = - 23

We have to given that,

An expression is,

- 4 (x - 5) + 8x = 9x - 3

Now, We can simplify the expression for equivalent expression,

- 4 (x - 5) + 8x = 9x - 3

Apply distributive property, we get;

- 4x + 20 + 8x = 9x - 3

4x + 20 = 9x - 3

4x - 9x = - 20 - 3

- 5x = - 23

Therefore, The equivalent expression is,

⇒ - 5x = - 23

Which polynomial is prime?

O x²-x-2
O x²-12x + 11
Ox²+2x-8

Answers

Answer:

The correct answer is x^2 + x + 1.

Step-by-step explanation:

A prime polynomial is one that cannot be factored. To solve this problem, we can use the process of elimination by eliminating all answer choices that can be factored.

x^2 - x - 2 = (x - 2)*(x + 1)

x^2 - 12x + 11 = (x - 11)*(x - 1)

x^2 + 2x - 8 = (x + 4)*(x - 2)

Since we cannot factor x^2 + x + 1, and we can factor all of the other answer choices, we know that x^2 + x + 1 is the answer.

*WILL GIVE BRAINLIEST* The table below contains partial data points of Red Bird's trajectory.

Answers

Horizontal distance traveled is 12unit, Equation in standard form is y = -4x² + 120x - 680 and Equation in vertex form is y = -4(x - 15)² + 220

Horizontal Distance Traveled

To find the horizontal distance traveled by Red Bird, we need to calculate the difference between the largest and smallest values of the X-axis data points. In this case, the horizontal distance traveled is:

Horizontal Distance Traveled = Largest X value - Smallest X value

                = 17 - 5

                = 12 units

The horizontal distance traveled by Red Bird is 12 units.

Equation in Standard Form

To find the equation in standard form, we need to determine the equation of a quadratic function that fits the given data points. Since we have more than three data points, we can use a quadratic regression to find the equation.

Using a regression tool or mathematical software, the equation in standard form for the given data points is:

y = -4x² + 120x - 680

Equation in Vertex Form

To find the equation in vertex form, we can convert the equation from standard form to vertex form by completing the square. The vertex form of a quadratic equation is given by:

y = a(x - h)² + k

To convert the equation to vertex form, we need to rewrite it by completing the square. The steps are as follows:

y = -4x² + 120x - 680

First, factor out the common coefficient -4:

y = -4(x² - 30x + 170)

To complete the square, we need to add and subtract the square of half the coefficient of x, which is (30/2)² = 225:

y = -4(x² - 30x + 225 - 225 + 170)

Now, rewrite the equation by grouping:

y = -4((x - 15)² - 55)

y = -4(x - 15)² + 220

The equation in vertex form is:

y = -4(x - 15)² + 220

So, the equation in vertex form for the given data points is y = -4(x - 15)² + 220.

The larger of two numbers is 15 more than the smaller number. If the sum of the two numbers is 27, find the two numbers.

Larger Number:
Smaller Number:

Answers

Answer:

Larger number: 21

Smaller number: 6

Step-by-step explanation:

Step 1: Make equations.

x ... larger number

y ... smaller number

First equation: The larger of two numbers is 15 more than the smaller number.

x = y + 15

Second equation: Sum of the two numbers is 27.

x + y = 27

Step 2: Solve the system of equations.

First equation: x = y + 15

Second equation: x + y = 27

Substitute x in second equation with x from first.

x + y = 27

(y + 15) + y = 27

Solve for y.

y + 15 + y = 27

2y = 27 - 15

2y = 12

y = 6

Substitute the calculated value of y back in first equation to get x.

x = y + 15

x = 6 + 15

x = 21

Using linear functions, it is found that the two stocks will be nearly equal in 30 months.

What is a linear function?

A linear function is modeled by:

y = mx + b

In which:

m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

Each of the stocks can be modeled by these following functions:

S1(t) = 39.63 + 0.3t.S2(t) = 24.45 + 0.8t.

They will be equal when:

S1(t) = S2(t).

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relationship between sides of a right triangle and its angles.

__

setup

The geometry of this problem can be modeled by a right triangle, so these relations apply. We are given an angle and adjacent side, and asked for the opposite side, so the relation of interest is ...

  Tan = Opposite/Adjacent

Using the given values, we have ...

  tan(24°) = AC/AB = (tree height)/(distance from tree)

  tan(24°) = AC/(22 m)

Multiplying by 22 m gives ...

  tree height = AC = (22 m)·tan(24°) ≈ 9.79503 m

In a graph, x represents the number of months since a business opened, and y represents the total amount of money the business has earned. The following three points are from the graph:

(2, 1990) (5, 4225) (9, 7205)

Find the slope and y-intercept. Explain what each represents.

Answers

The slope of the graph is 745 and the y-intercept of the graph is 500

How to determine the slope?

The points are given as:

(2, 1990) (5, 4225) (9, 7205)

The slope is calculated using:

m = (y2 - y1)/(x2 - x1)

So, we have:

m = (4225 - 1990)/(5 - 2)

Evaluate

m = 745

This means that the amount earned per day is 745

Hence, the slope of the graph is 745

How to determine the y-intercept?

In (a), we have

m = 745

To calculate the y-intercept, we use the following points

(x1 , y1) = (0,y)

Recall that:

m = (y2 - y1)/(x2 - x1)

So, we have:

745 = (4225 - y)/(5 - 0)

Evaluate the difference

745 = (4225 - y)/(5)

Multiply both sides by 5

3725 = 4225 - y

Solve for y

y = 500

This means that the initial amount earned is 745

Hence, the y-intercept of the graph is 500
