On parallelogram ABCD below, if A(1, 1), B(8, 5), C(5,-5) and D(-2,-9), what are the coordinates of point E?
Answers
The coordinates of point E on the parallelogram are given as follows:
(3, -2).
How to obtain the coordinates of point E?The coordinates of point E are obtained considering that the point E is the midpoint of segment AC, hence it's coordinates are the mean of the coordinates of A and C.
Then the x-coordinate of point E is obtained as follows:
x = (1 + 5)/2 = 3.
The y-coordinate of point E is obtained as follows:
y = (1 - 5)/2 = -4.

The length of a rectangular prism is 2 more than three times the width w. The volume of the prism is 3w^3+14w^2+8w.[tex]3w^{3} +14w^{2} +8w[/tex] What is a simplified expression for the height of the prism?
Answers
The volume of a rectangular prism is given by the product of its length, width, and height, which is V = l * w * h, where l is the length, w is the width, and h is the height.
We are given that the volume of the prism is 3w^3 + 14w^2 + 8w. We can use this information to find the height of the prism by dividing the volume by the product of the length and width.
We know that the length of the prism is 2 more than three times the width (l = 3w + 2). Therefore, the product of the length and width is l*w = (3w + 2) * w = 3w^2 + 2w
Now we can divide the volume by the product of the length and width to find the height of the prism:
V / (l * w) = (3w^3 + 14w^2 + 8w) / (3w^2 + 2w) = 3w + 14 + 8/3w^2 + 2w
So, the height of the prism is 3w + 14 + 8/3w^2 + 2w
Which is a simplified expression for the height of the prism, in terms of the width.

Answers
The equation which represents the same line as the points in the table is y = -3/4 x + 2. (Option C)
The equation of the points given in the table can be determined by using the slope-intercept form which is given by:
y = mx + b
where m is the slope of the line and b is the y-intercept.
The slope of the line can be determined by:
m = rise/run = Δy/ Δx = (y2 – y1)/(x2 – x1)
Hence, taking two points from the table say (-4, 5) and (0, 2)
m = (2 – 5)/(0 – (-4)) = -3/4
y intercept is the value of y when x = 0
From the table, y-intercept b = 2
Hence, the equation of the line is: y = -3/4 x + 2

Step-by-step explanation:
√21 = 4.58257569495584 which is a non-terminating decimal.
Therefore √21 is irrational.
Answer: No, it cannot be a rational number.
Step-by-step explanation:
A rational number is defined to be a whole number (ex. 1, 2, 3) or can be decimals that continuously repeat the digits after the point. In the case of a square root, they can be rational--but this only applies to perfect squares: √100, √64, √16, etc, which would give an outcome of a whole number. Therefore, √21 is not a rational number, as the decimal value is 4.57257, and is not continuous (ex. 3.666666).

Answers
Answer:
(a) 7.68 dollars
(b) 1927.07 pesos
Step-by-step explanation:
Setting up a conversion factor will be helpful in helping us solve this problem. A conversion factor shows the relationship between two different units, and and is used to convert from one unit to the other.
Our conversion factor is 1 U.S. Dollar = 19.61 Mexican pesos. To convert units, we can turn the conversion factor into a ratio (U.S. dollar ÷ 19.61 Mexican pesos or vice versa) and then multiply the given amount by the ratio. The unit that we want to end up with should always be in the numerator, and the unit we want to convert from should always cancel out in the denominator. This will be demonstrated when we solve the problems below:
(a) We want to convert from pesos to dollars, so we will multiply by the conversion factor (1 dollar / 19.61 pesos).
150.68 pesos (1 dollar / 19.61 pesos) = 7.68 dollars(b) Now we want to convert from dollars to pesos, so we will multiply by the conversion factor (19.61 pesos / 1 dollar).
98.27 dollars (19.61 pesos / 1 dollar) = 1927.07 pesosWhat is a cross section cut to the angle of the base of a rectangle prim
