The area of a square field is 3.24hectares . Find its perimeter in decimeters

Answer:

A , B, D, F

Step-by-step explanation:

A) ∠1 ≅ ∠ 4    {Vertically opposite angles are congruent}

B) m∠2 + ∠4 + ∠6 = 180°    {Straight line angles}

    ∠6 ≅ ∠3

⇒ ∠2 + ∠4 + ∠3 = 180°

D) ∠2 + ∠3 + ∠4 = 180°   {Straight line angles}

f) ∠2 + ∠3 = ∠5 + ∠6   {Vertically opposite angles}

EXPLANATION:

Given;

We are given a graph of a function.

Required;

We are required to determine from the graph if the function is even, odd or neither even nor odd.

Solution:

To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.

Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.

However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.

Therefore, the graph depicted is an odd function

ANSWER:

The function is an ODD function

Answer: the answer is (0,-8)

Answer:

The percent error of Ming’s estimate is 40%.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

here, it is given that :

Estimated number of members in his bicycle club by the end of summer = 21

Actual number of members in his bicycle club by the end of summer = 15

Now, the percent error of Ming’s estimate :

percent error = {(21-15)/15 } x 100

percent error = (6/15) x 100

percent error = 40%

Therefore, the percent error of Ming’s estimate is 40%.

Primarily use the Distributive Property to solve this equation.

3(5 - x) - 2(5 + x) = 3(x + 1)

Distribute the outer terms.

3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3

Now, isolate all x terms.

-5x + 5x + 5 = 3x + 5x + 3
5 = 8x + 3
5 - 3 = 8x + 3 - 3
2 = 8x
2/8 = 8x/8
x = 1/4

The given series is a geometric sequence with a common ratio of 1/2 it is also written as 0.5.

A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.

Number sequences are groups of numbers that adhere to a pattern or rule. A geometric sequence is one in which the rule is to multiply or divide by a specific number each time.

We have,

20, 10, 5, …

The distinction between consecutive terms is:

10 - 20 = -10

5 - 10 = -5

Since -10 ≠ -5, therefore the given series has no standard difference, which means the given sequence is not arithmetic.

The ratio between consecutive terms is:

10/20 = 1/2

5/10 = 1/2

The given series has a common ratio of 1/2, which means the given sequence is geometric.  it is also written as 0.5.

The value of x in the given figure is 10.

In the given triangle,

∠ADC = ∠BDC =  90°

Hence the triangles ΔACD and ΔBCD are right-angle triangles. Thus we can apply Pythagoras' theorem in both triangles.

So in ΔACD,

CB² = BD² + DC²

And in ΔBCD,

CA² = AD²+ DC²

But, CA = 15 and CB = x + 5

So, (x + 5)² = BD² + DC²

15² = AD² + DC²

⇒225 = AD² + DC²

Here, BD = AD as given in the figure

Replacing BD with AD in the first equation we get,

(x + 5)² = AD² + DC²

Now, equate the values of AD² + DC² to obtain the value of x,

(x + 5)² = 225

⇒ x² + 25 + 10x = 225

⇒ x² + 10x - 200 = 0

⇒ x² + 20x - 10x - 200 = 0

⇒x(x + 20) - 10(x + 20) = 0

⇒(x + 20)(x - 10) = 0

Thus x = -20, 10

Hence the value of x is 10.

After solving the quadratic equation x² + 3x = 40 using the quadratic formula, (A)  x = –8, x = 5  

We can solve this quadratic formula by following a few steps.

The given equation is,

x² + 3x =40

Let's subtract 40 from both sides,

x² + 3x - 40 =40 - 40

Or, x² + 3x - 40 = 0

Now, we have to find a suitable pair of factors of -40 which is capable to generate +3 ( coefficient of x ).

The required pair is 8 and -5, and ( 8 - 5 ) = 3    

[ -40 = 8 × -5 ]

Therefore, x² + 3x - 40 = 0

Or, x² + ( 8 - 5 )x - 40 = 0

Or, x² + 8x - 5x - 40 = 0

Or, x ( x + 8 ) - 5 ( x + 8 ) = 0   [ taking x and 5  as common ]

Or, ( x + 8 ) ( x - 5 ) = 0            [ taking ( x + 8 ) as common ]

If the multiplication or product of two or more terms is zero, then we can write each term as zero.

               ( x + 8 ) = 0

               Or, x = -8        ( by subtracting 8 from both sides )

              ( x - 5 ) = 0

              Or, x = 5           ( by adding +5 with both sides )

Now, we can conclude that x = -8 and 5.

The equation in slope-intercept form of the line passing through the given points is,  y = (-1/2)x + 1

A table containing values of x and y is given:

x           y

-2          2

0           1

2           0

4           -1

So the points on the line are:

(-2,2), (0,1), (2,0) and (4,-1)

The equation in slope-intercept form of a line is,

   y = mx + c,

where m is the slope of the line and c, the y-intercept of the line.

So we need to find the slope and the y-intercept of the line from the given table values.

Let (x₁, y₁) = (-2,2) and (x₂, y₂) = (0,1).

Then slope of the line, m = (y₂-y₁)/(x₂-x₁)

                                           = (1-2)/(0- -2)

                                           = -1/2

The y-intercept of a line is the y-co-ordinate of the point which intersect the y-axis. I.e., it is the y-co-ordinate of the point at which x = 0.

From the table, when x = 0, y = 1.

Hence the y-intercept, c = 1.

So finally, the equation in slope-intercept form of the line is,

y = (-1/2)x + 1

Option C is the correct answer.

 A function is a relationship between inputs where each input is related to exactly one output.

A function has an input and an output.

Example:

f(x) = x + 1

f(1) = 1 + 1 = 2

Input = domain = 1

Output = range = 2

We have,

Function:

y = x² - 1

The domain of a function = {-2, -1, 0, 1, 2 }

Let y = f(x)

x = -2, -1, 0, 1, 2.

f(-2) = 4 - 1 = 3

f(-1) = 1 - 1 = 0

f(0) = 0 - 1 = -1
