The area of the octagon having an apothem of 6 meters and a side length of 7 meters is 168 meter square

Using the formula:

Area of an octagon = perimeter * apothem / 2

Note that perimeter of an octagon = 8 a

where a is the length of it's side

Perimeter = 8 * 7

Perimeter = 56 meters

Apothem = 6 meters

Substitute into the formula

Area = 56 * 6/ 2

Area = 336 / 2

Area = 168 meter square

Thus, the area of the octagon is 168 meter square

Coordinate of vertex is the point where there's a unique (only one) value of y for x :

Since it's a downward parabola, it doesn't have defined minima, as it's value reach [ - infinity ]

Answer:

60 minutes

Step-by-step explanation:

we can see that the number of minutes increases by 8 each day

(12 + 8 = 20, 20 + 8 = 28, 28 + 8 = 36...)

So, because we have the value for the previous day (day 6) we know that we can simply add 8

52 + 8 = 60

So, the predicted number of minutes for day 7 is 60

Phrase D best describes the relationship indicated by the scatter plot. There is no correlation.

In an effort to demonstrate how much one variable is influenced by another, scatter plots are used to depict data points on a horizontal and vertical axis.

When there is no connection between two variables, it is called a zero correlation. For instance, there is no correlation between IQ level and the quantity of tea consumed.

Answer:

  (-1, -5)

Step-by-step explanation:

Each point on a graph is the ordered pair (x, f(x)). Then the point M(-1 -3) is the ordered pair (-1, f(-1)) where f(-1) = -3.

A point on the shifted graph will be ...

  (x, f(x) -2)

Then for x = -1, the point is ...

  (-1, f(-1) -2) = (-1, -3 -2) = (-1, -5)

The minimum on the shifted curve is M'(-1, -5).

Answer:

Part A = 36z² - 9z + 8

Part B = 5z³ + 4z² + 16z - 23

Part c = Yes.

Step-by-step explanation:

Polynomials : Polynomials are algebraic expressions that consist of variables and coefficients.

Trapezium: A trapezium is a convex quadrilateral with exactly one pair of opposite sides parallel to each other.

Given the length of sides :

Side 1: 11z² - 4z + 2

Side 2: -2z + 3 + 12z²

Side 3: 3 - 3z + 13z²

and The perimeter of the trapezoid is 5z³ + 40z² + 7z - 15.

PART A:

The total length of sides 1, 2, and 3 of the trapezoid is obtained by the sum of the trapezoid :

11z² - 4z + 2 + (-2z + 3 + 12z²) + 3 - 3z + 13z²

11z² - 4z + 2 - 2z + 3 + 12z² + 3 - 3z + 13z²

36z² - 9z + 8

PART B:

The length of the fourth side of the trapezoid is given by the difference between the perimeter of the trapezoid and the sum of  length of sides 1, 2, and 3.

5z³ + 40z² + 7z - 15 - 36z² + 9z - 8

5z³ + 4z² + 16z - 23

PART C:

From part A, we can see that the addition of polynomials results in a polynomial.

Likewise, the subtraction of polynomials results in a polynomial.

Therefore, we can say that the polynomials are closed under addition and subtraction.

Answer:

Step-by-step explanation:

the diagonals of a parallelogram bisect each other , then

2 AE = AC ( substitute values )

2(2x - 5) = 22 ( divide both sides by 2 )

2x - 5 = 11 ( add 5 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

Assuming that both lines are parallel, we conclude that C = 74°.

Here we can see that both of the lines that go upwards are parallel lines. This means that C and the 74° angles are opposite angles.

Then if we say that x is the angle at the right of the 74°, we must have that:

x + 74° = 180°

x = 180° - 74° = 106°

And we also must have that:

x + C = 106° + C = 180°

Solving for C:

C = 180° - 106° = 74°

C = 74°.

After 7 days, the balance will be Rs. 628.

(A) The slope of the given function is 40.

(B) In point - slope form it is y - 600 = 40x

   In Slope - intercept form it is y = 40x + 600

   In Standard form it is 40x - y + 600 = 0

(C) g(x) = 4x + 600

(D) After 7 days, the balance will be Rs. 628

Let g(x) = y

(A) We know slope = change in y/change in x

                               = 720-600/3-0

                               = 120/3

                               = 40

Therefore, the slope of the given function is 40.

(B) We know that the equation of a line

in point - slope form is y - y₁ = m(x - x₁)

where ( x₁, y₁ ) is a point on the line

where m is the slope

Therefore, substituting the values, we get,

y - 600 = 40(x - 0)

=> y - 600 = 40x                                    --(i)

Slope - intercept form is y  = mx + b

where m is the slope

and b is the y-intercept

To find y intercept, we substitute x = 0 in equation (i)

=> 40*0 - y + 600 = 0

=> -y + 600 = 0

=> y = 600

Therefore, substituting the values, we get,

     y = 40x + 600

in Standard form is ax + by = c

where a, b, and c is constant

Converting the equation found above into the standard form

=> y = 40x + 600

=> 40x - y + 600 = 0

(C) As we had assumed g(x) to be y

=> From equation (i),

 y - 600 = 40x    

can be written as g(x) - 600 = 4x

=> g(x) = 4x + 600                                    --(ii)

(D) We need to find the balance in the bank account after 7 days

=> Balance [g(x)] when x = 7

Therefore, substituting the value of x in equation (ii)

=> g(x) = 4*7 + 600

          = 28 + 600

          = 628

Therefore, after 7 days, the balance will be Rs. 628.
