the number that goes in the blank is 8
Step-by-step explanation:
Answer: This coil will not be enough to complete the job.
Step-by-step explanation:
The circumference of the coil of wiring can be calculated with:

Where r is the radius and 
The radius can be calculated by dividing the diameter by 2. Then:

Convert 9 inches to yards (1 yard=36 inches):

Substitute this radius into the formula:

Since there are 21 circles of wire, you need to multiply
by 21:

The coil has 32.97 yards of wire and Alex needs 34 yards, therefore, this coil will not be enough to complete the job.
The way to write this expression in mathematics is A'∩B
<h3>How to solve for the expression</h3>
In order to get the right way to write this expression we have to break it down in two parts.
First we are told that some of the elements are not in A.
This is represented as A'.
Then we are told that they are in the set B. Hence we have it written as B.
Then the expression not in set A but are in set B would be written as
A'∩B.

Answer:
r=24
s=21
Step-by-step explanation:
I use proportion of 2 to 3
I multiply 16 and 3/2 to get r
r=24
I multiply 14 and 3/2 to get s
s=21
Answer:
The domain of the function is the set of all real numbers; the range of the function is the set of all nonnegative real numbers; the graph has an intercept at (0, 0); and the graph is symmetric with respect to the y-axis.
Step-by-step explanation:
This is not a square root function, this is a quadratic function, which has an x².
The domain, or set of x-values, is all real numbers. This is because all numbers work for x.
The range, or set of y-values, is the set of all nonnegative real numbers. This is because all numbers we get for y are positive real numbers.
The graph intersect both the x- and y-axis (x-intercept and y-intercept) at (0, 0).
The graph is decreasing on the interval x<0 and increasing on the interval x>0, not the other way around.
The graph has a minimum at (0, 0), not a maximum.
The graph can be folded in half along the y-axis, so it is symmetric with respect to the y-axis.
