The length of each side of the playground is 150 feet.

From the question, we are to determine the length of each side of the playground.

From the given information,

The perimeter of a square is given by the formula,

P = 4l

Where P is the perimeter of the square

and l is the length of a side of the square

"The playground at DeVille Elementary School is square-shaped, and has a perimeter of 600 feet."

That is,

P = 600 feet

Now, we will determine the value of l

Substitute the value of P into the equation

P = 4l

600 = 4l

Divide both sides by 4

600/4 = 4l/4

150 = l

Therefore,

l = 150 feet

Hence, the length is 150 feet

The value of x for the given triangle is 4.5

A triangle is a geometric figure with three edges, three angles and three vertices. It is a basic figure in geometry.

The sum of all three angles of a triangle is always 180°

In the given triangle ABC,

∠A=(9x+16)°, ∠B=(6x+15)°

And the extrior angle ∠C=(19x+3)°

Use the external angle property,

The sum of two interior angles is equal to an exterior angle.

Therefor,

∠C=∠A+∠B

The required graph of the given line y = -(2/3)x + 1 is shown in the attached figure.

The equation of the line is given in the question as:

y = -(2/3)x + 1

First, we have to find the intercepts of the equation y = -(2/3)x + 1

The y-intercept is the value of y when the value of x is appropriately zero.

For x = 0

y = -2/3(0)+1

y = 1

The y-intercept is the point where (0.1)

Determine the x-intercept.

The x-intercept is the value of x when the value of y equals zero.

For y = 0

0 = (-2/3)x + 1

-1 = (-2/3)x

x = 3/2 or 1.5

The y-intercept is the point (1.5,0).

To graph, the line, draw the intercepts and connect the dots as indicated in the image.

As a result, the graph for the line y = -(2/3)x + 1 is provided below.

The equation of the line in point slope form is as follows:

Linear equation can be represented in different form such as point slope form, slope intercept form, standard form and general form.

Therefore, equation in point slope form can be represented as follows:

y - y₁ = m(x - x₁)

where

Therefore, let's find the point slope form of the lines.

1) through: (5, 4) and (-2, 5)

m = 5 - 4 / -2 - 5

m = 1 /- 7 = - 1 / 7

Therefore,

y - 4 = - 1 / 7(x - 5)

2) through: (4, -5) and (0, 2)

m = 2 + 5 / 0 - 4

m = 7 / -4 = - 7 / 4

Therefore,

y + 5 = - 7 / 4(x - 4)

3) through: (0, 4) and (2, 1)

m = 1 - 4 / 2 - 0

m = - 3/ 2

Therefore,

y - 4 = - 3 / 2(x - 0)

Hi again! The equation to the function would be..

y = 1/2x + 1 (assuming that the initial value is one)

The following are the answers:

a) 7 / (2a)³

b) 1/(4m)³ + 10³

c) (5a)³ - (4b)³

d) 1/(3x)³ + 1/(5y)³

e) (0.5x - 0.6y)²

f) (-a - 0.3)²

g) ((3/4)²a² + (2/3)²a)²

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

a)

(8 - 1) / 8a^3

= 7 / (2a)³

b)

1/64m^3 + 1000

= 1/(4m)³ + 10³

c)

125a^3 - 64b^3

= (5a)³ - (4b)³

d)

1/27x^3 + 1/125y^3

= 1/(3x)³ + 1/(5y)³

Now,

Polynomial is an expression of writing with more than one term.

We will write it in the form of:

(a + b)² = a² + 2ab + b²

(a - b)² = a² - 2ab + b²

e)

0.25x^2 - 0.6xy + 0.36y^2

= (0.5x)² - 2 x 0.5 x 0.6 + (0.6y)²

= (0.5x - 0.6y)²

f)

-a^2 + 0.6a - 0.09

-a² - 2 x (-a) x 0.3 - (0.3)²

= (-a - 0.3)²

g)

9/16a^4 + a^3 + 4/9a^2

((3/4)²a²)² + 2 x (3/4)²a² x (2/3)²a + ((2/3)²a)²

= ((3/4)²a² + (2/3)²a)²

Thus,

The following are the answers:

a) 7 / (2a)³

b) 1/(4m)³ + 10³

c) (5a)³ - (4b)³

d) 1/(3x)³ + 1/(5y)³

a) An equation that models the amount of storage as a function of the number of songs is y = -0.005x + 16

b)  Slope of the equation is -0.005 and the intercept of the equation is 16

Slope intercept form

Slope intercept form presents the graph of a straight line and is represented in the form of

y = mx + c.

where

y = y coordinate

m = slope

x = x coordinate

b = y intercept

Given,

Here we have the  table shows the amount of storage y (in gigabytes) on a music-playing device when there are x songs on the device

Now, we have to find the following:

a) Equation of the table

b) Slope and intercept.

In order to find the equation, we have to identify the slope an intercept of the table.

So, to find that we have to take two points from the table.

Then the selected points are

(0, 16), (242, 14.8)

By using these point we have to calculate the slope as,

m = (14.8 - 16) / (242 - 0)

m = -1.2/242

m = -0.005

Now, the intercept is calculated by using the point (0, 16) and the slope -0.005, then we get,

16 = -0.005(0) + c

c = 16

Therefore, the equation is y = -0.005x + 16.

The area of the square is (x²/2) square units.

We are given a square. The length of the diagonal of the square is x units. We have to find the area of the square in terms of "x".

Let the side of the square be denoted by the variable "s". We will use the Pythagorean theorem to find the length of the side of the square.

s² + s² = x²

2s² = x²

s² = x²/2

s = √(x²/2)

s = (x/√2)

The area of the square is given by the square of the side length. Let the area of the square be denoted by the variable "A".

A = s²

A = (x/√2)²

A = x²/2

Step-by-step explanation:

Hi,  you are studying trigonometry :P  nice  

conterminal means stopping at the same place, right?  sooo what is the same place for 659°  compared to our only once around the circle of 360°   since 720° is twice around a circle our 659° is less than that so just subtract 360° from 659° to get the co-terminal angle.

659-360=299°

299° is the co-terminal angle

270 is the line between the 3rd and 4th quadrant,  so this is definitely in the 4th quadrant.

let's just count backwards (CW) from zero degrees till we get to our 299° angle going in the forward (CCW) direction.    so 299-360= -61°

the reference angle is 61°

Richard earned a cumulative GPA of 2.5 in all four semesters.

Here, we know that the cumulative GPA for the first 3 semesters is 2.0

He had earned 42 credits in total in all three semesters.

Cumulative GPA = Total points earned/credits rewarded

Hence,

Total points earned in 3 semestes= 2 X 42

= 84 points

In the fourth semester,

he had earned 14 credits with a GPA of 4.0

Hence total points earned = 4 X 14

= 56 points

Therefore, total points earned in all four semesters = 84 + 56 points

140 points

Total credits = 14 + 42
