At times, it is necessary to make plans even when all of the facts are not there. Bernard is currently facing such a dilemma. Be

rnard is asked to create a swimming pool and deck design for a new series of model homes currently being designed. Each home will have varying pool sizes depending on the lot size; however, there will be some similarities, so polynomial expressions will be used. Your task will be to help Bernard.
To fit the dimensions of the various land spaces, he realizes that the length of the pool has to be three times the size of the width plus 3 and the depth has to be 7 less than twice the length.


A. Create a variable to represent the width of the pool. Determine the expressions to represent length and the depth in terms of the width variable.

B.Determine the polynomial expression to represent the area of land space that the pool will cover.

C.Using the area and the depth expressions, determine the polynomial expression that is used to represent the volume.

D.Classify the volume polynomial by degree and number of terms.

A. Let us assume the width of the pool = x
Then
Length of the pool = 3x + 3
Depth of the pool = 2(3x + 3) - 7
                            = 6x + 6 - 7
                            = 6x - 1
B. Area of the land space = Width * length
                                          = x * (3x + 3)
                                          = 3x^2 + 3x
C. Volume of the pool = (6x - 1) * (3x^2 + 3x)
                                    = 18x^3 + 18x^2 - 3x^2 - 3x
                                    =  18x^3 + 15x^2 - 3x
 D. The highest degree is actually 3 and the number of terms that we get is also 3.

A dolphin jumps 54 times in a 6 hour period. At this rate, how many jumps would be expected in a 2-hour period?
Lemur [1.5K]

Answer:

The dolphin will jump 18 times in 2hours.  

Step-by-step explanation:

Find the jumps per hour: 54/6 = 9

^This means that the dolphin jumps 9 times in an hour.

9*2 (hours) = 18

The dolphin will jump 18 times in two hours.

Based on the graphs of the equations y = x + 7 and y = x2 – 3x + 7, the solutions are located at points:
Triss [41]

The correct option is A. (4, 11) and (0, 7).

The solution of the equations y = x + 7 and y = x² – 3x + 7, the solutions are located at points: (4, 11) and (0, 7).

<h3>What is the system of linear equation?</h3>

Estimate the y-intercept, slope, and express the equation in the form of the y-intercept (y = mx + b) to find the graphed equation. The slope is the difference between the y- and x-axis values.

A graph equation is an equation in graph theory where the unknown is a graph. Isomorphic ideas are one of the key issues in graph theory.

The equations are; y = x + 7 and y = x² - 3x + 7

At the solution, the u-values are equal, which gives;

y = y

x + 7 = x² - 3·x + 7

x² - 3·x + 7 - (x + 7) = 0

x² - 4·x = 0

x·(x - 4) = 0

x = 4, or x = 0

When x = 4, y = 4 + 7 = 11

When x = 0,

         y = 0 + 7 = 7

Therefore, the solution for the equations  y = x + 7 and y = x² - 3x + 7 are are located at points: (4, 11) and (0, 7).
