The first five terms of a geometric sequence with first term 2 and common ratio (-2) are 2, -4, 8, -16, 32

The given parameters:

a₁ = 2, r = -2

r is the common ratio, hence, the given sequence is a geometric sequence.

In a geometric sequence, the formula for the nth term is given by:

       a(n) = a(1) . rⁿ⁻¹

We can also find the terms using recursive formula. The nth term of a geometric sequence is equal to the (n-1)th term times the common ratio, r. Mathematically,

       a(n) = a(n -1) . r

Let us start from n = 1

a(1) = 2  (given)

a(2) = a(1) . r = 2 . (-2) = -4

a(3) = a(2) . r = -4 . (-2) = 8

a(4) = a(3) . r = 8 . (-2) = -16

a(5) = a(4) . r = -16 . (-2) = 32

Thus, the first five terms are 2, -4, 8, -16, 32

The equation of the proportional relationship in the table attached below is: y = 40x.

Equation of a proportional relation is modelled as, y = kx. k = y/x, using any pairs of values for a given table. If the table is represents a proportional relationship, y/x for every pair of values would be the same.

Distance in miles = y

Time in hours = x

k = y/x = 80/2 = 120/3 = 160/4 = 40.

The relation represented by the table is proportional because y/x is the same for all pairs of values.

Substitute k = 40 into y = kx

y = 40x.

Based on the calculations, the coordinates of the y-intercept are (0, -9).

In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope, m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope, m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Substituting the given parameters into the formula, we have;

Slope, m = (-4.5 - 3)/(-3 + 8)

Slope, m = -7.5/5

Slope, m = -1.5.

Mathematically, the standard form of the equation of a straight line is given by;

y - y₁ = m(x - x₁)

At point (-8, 3), we have:

y - 3 = -1.5(x + 8)

y - 3 = -1.5x - 12

y = -1.5x - 12 + 3

y = -1.5x - 9

The equation of line which contains points (2,4) and (0,-2) will be y = 3x - 2.

It is given that a line contains points (2,4) and (0,-2).

We have to find out the equation of the line.

What is the equation of line in slope intercept form ?

The equation of line in slope intercept form is y = mx + c , where m is the slope and c is the y-intercept.

As per the question ;

Line contains points (2,4) and (0,-2)

We know that slope intercept form of line is ;

y = mx + c

∴  (2,4) and (0,-2) must satisfy the equation because the line contains them.

So ,

For x = 2 and y = 4 ;

the equation y = mx + c becomes ;

4 = 2m + c ------ ------ ------ ---- (1)

Also ;

For x = 0 and y = -2 ;

the equation y = mx + c becomes ;

-2 = 0 + c

or

c = -2

Put the value of c in equation 1 ;

i.e.,

4 = 2m - 2

2m = 6

or

m = 3

So ,

the equation of line which contains points (2,4) and (0,-2) will be ;

y = (3 × x) - 2

y = 3x -2

Thus , the equation of line which contains points (2,4) and (0,-2) will be y = 3x - 2.

The algebraic expression (z+0)+y+0 is equivalent to (z+y) by the identity property of addition.

An algebraic expression is a simple and random combination of  constants and variables .

An expression constructed using integer constants, variables, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).

The identity property of addition states that when a constant number is added to zero the value of the expression remains the same.

Since the absolute value of 0 is nothing so adding or subtracting zero from a constant does not change the value of the constant.

I.e, g+0=0 here the value of g does not change.

The total percentage of the all the colours is 100%.

Divide the value of blue by 3.6 because 360 degrees /100 percent = 3.6.

The total percentage of blue shown by the pointer of spinner is 30%.

the horizontally shrunk function by a scale factor K = 3 is modeled by:

g(x) =  |3*x| + 5

For any function f(x), we define a horizontal shrink or compression by a scale factor K as:

g(x) = f(K*x)

In this case the function is:

f(x) = |x| + 5

And the scale factor is K = 3.

Then we can write the compression as:

g(x) = f(3*x)

Replacing the actual function we will get:

g(x) = f(3*x) = |3*x| + 5

Then the horizontally shrunk function by a scale factor K = 3 is modeled by:

Answer:      302 degrees

Step-by-step explanation:

The equation of the line in slope-intercept form is y + 2 = (5 / 3) · (x + 5).

Linear equations are first order polynomials whose slope-intercept form is introduced below:

y - y₁ = m · (x - x₁)       (1)

Where:

And the slope of the line is determined by the secant line formula:

m = Δy / Δx                (2)

Now we proceed to determine the equation of the line in slope-intercept form:

m = [5 - (-5)] / [4 - (- 2)]

m = 10 / 6

m = 5 / 3

y + 2 = (5 / 3) · (x + 5)
