Step-by-step explanation:
Concrete workers are busy preparing to pour a rectangular patio on the rear of Miguel's new house. The workers have laid out, using boards, what appears to be rectangle to frame where the concrete will go.
What could the workers do to ensure the patio is really rectangular before pouring the concrete?
Answer:
See Explanation below.
Step-by-step explanation:
What the workers can do to ensure the patio is truly rectangular, before pouring the concrete, is to measure the length of the sides of the patio.
This requires full knowledge of the physical properties of a rectangle.
The opposite sides of a rectangle (the two sides which go in the same direction or which are parallel to each other) are equal in length and one set of parallel sides must be longer than the other set of parallel sides.
These are the conditions that the patio must satisfy, to be truly rectangular.
Once the workers have made sure of this, they can go ahead and pour the concrete.

Select all of the solutions to this equation:
(x – 7)(x + 1)(x – 9) = 0
Given the function g(x) = x2 + 10x + 19, determine the average rate of change of
the function over the interval -9 < x < 1.
Answer:
The average rate of change of the function over the interval is of 2.
Step-by-step explanation:
Suppose we have a function f(x), over an interval (a,b).
It's average rate of change over the interval is given by:
[tex]A = \frac{f(b) - f(a)}{b - a}[/tex]
In this question:
[tex]g(x) = x^2 + 10x + 19[/tex]
Over the interval -9 < x < 1, so [tex]a = -9, b = 1[/tex]. So
[tex]A = \frac{g(1) - g(-9)}{1 - (-9)} = \frac{g(1) - g(-9)}{10}[/tex]
We have that:
[tex]g(1) = 1^2 + 10(1) + 19 = 1 + 10 + 19 = 30[/tex]
[tex]g(-9) = (-9)^2 + 10(-9) + 19 = 81 - 90 + 19 = 10[/tex]
So
[tex]A = \frac{30 - 10}{10} = \frac{20}{10} = 2[/tex]
The average rate of change of the function over the interval is of 2.

at 6:00 a.m., the temperature is 58°. At 2:00 p.m., temperature is 76°. Find the rate of change in degrees per hour during this time.
Answer:
The rate of change is of 2.25 degrees per hour.
Step-by-step explanation:
The rate of change in degrees per hour is given by by the change in temperature divided by the change in time(by number of hours).
In this question:
From 6 am to 2 pm, there are 12 - 6 + 2 - 0 = 6 + 2 = 8 hours
The change in temperature was of 76 - 58 = 18º
Rate of change:
18º/8 = 2.25º
The rate of change is of 2.25 degrees per hour.

(b) experimental sampling
samples
Answer:
a)[tex]X=1728[/tex]
b)[tex]X'=220[/tex]
Step-by-step explanation:
From the question we are told that
Population size N=12
Sample size n=3
a)Generally using theoretical sampling we can solve mathematically
[tex]X=N^n[/tex]
[tex]X=12^3[/tex]
[tex]X=1728[/tex]
b)Generally using experimental sampling we can solve mathematically
[tex]X'=^NC_n[/tex]
[tex]X'=^1^2C_3[/tex]
[tex]X'=220[/tex]

The length of a living room is 12 feet and its width is 10.5 feet. The length of the room is being expanded by x feet.
A. Write an expression to represent the new area of the living room in square feet.
B. Expand the expression.
Answer:
A) A= 10.5(12 +x)
B) A= 10.5x +126
Step-by-step explanation:
A) Length of living room= 12 ft
Width= 10.5 ft
Since the length expanded by x ft,
New length of living room= (12 +x) ft
Area= length ×width
Let the new area of the living room be A ft².
A= 10.5(12+x)
B) To expand the expression, multiply 10 to each term and constant in the bracket on the right hand side of the equation.
A= 10.5(12 +x)
A= 10.5(12) +10.5x
A= 126 +10.5x
Translate and solve: 662% of what number is 3641?
Answer:
550Step-by-step explanation:
To find the percent of a number, we multiply the number by the decimal form of the percent. The decimal form of a percent can be found by moving the decimal point two places to the left.
Example: 45% = 0.45
In this case, we need to work backward. So, instead of multiplying, we will divide to undo the multiplication.
662% = 6.62
We need to divide 3641 by 6.62 to get the number that 3641 is 662% of. This number will be a smaller number since 662% of a number will be larger than the original number, This is because it is greater than 100%, which would be the number.
Example 100% of 6 is 6 since 6 x 1.00 is 6.
3641/6.62 = 550
However, we can also verify this by multiplying 550 by 6.62 to find 662% of 550.
6.62 x 550 = 3641
