cite a real life situation that describes the concept of direct and inverse variation. create your own word problem and answer it. present your answer with table of values, graph and equation
A need a appropriate answer, thanks...
Answers
Step-by-step explanation:
An example of direct variation would be the relationship of distance with time when speed is constant.
d = stLet's assume you travel at the speed of 60 mph. The distance at 0, 0.5, 1, 2 hours would be 0, 30, 60, 120 miles.
d = 60tThis is a linear relationship and produces a graph of line.
See the graph.
--------------------
An example of inverse variation would be the time to complete the same work as number of workers increase.
t = w/p, where w is work (constant), p- number of workersAssume 5 workers complete wok in 20 days, 10 workers do same in 10 days, 20 workers do in 5 days.
t = 100/pThis relationship produces a curved line.
See the graph.

what are the leading coefficient and degree of the polynomial?
Answers
Answer:
leading coefficient: 2degree: 7Step-by-step explanation:
The degree of a term with one variable is the exponent of the variable. The degrees of the terms (in the same order) are ...
6, 0, 7, 1
The highest-degree term is 2x^7. Its coefficient is the "leading" coefficient, because it appears first when the polynomial terms are written in decreasing order of their degree:
2x^7 -7x^6 -18x -4
The leading coefficient is 2; the degree is 7.
__
Additional comment
When a term has more than one variable, its degree is the sum of the exponents of the variables. The term xy, for example, is degree 2.
Given that X varies directly as Y³ and X = 54, Y = 3. find X 10 Y = 5 what is the relationship between X and Y?
Answers
Answer:
x=6y3
Step-by-step explanation:
we first find the constant of proportionality where by we say; x= ky3
we're given x = 54
and y = 3
so
54=k(3cubed)
therefore
54= 9k
divide be 9 both sides to get k which is the constant
k=6
now rewrite the equation replacing k with 6
it will be...
X=6Y3

[2] A car is traveling at 55 MPH.
How long in minutes will it take, in minutes, to travel 33 miles?
Answers
Answer:
Step-by-step explanation:
So at 55 miles per hour you go 12 miles in a little over 13 minutes.
.
Hope this helps you to understand the problem and how to use the formula to solve it.
Distance = Speed * Time
.
You might be able to understand this by thinking, "If I go at 60 miles per hour for 2 hours,
how far do I travel?" The answer is:
.
Distance = 60 miles per hour* 2 hours = 120 miles
.
In the problem you are told that the distance to be covered is 12 miles. The speed is 55 miles
per hour. Put these into the equation and you get:
.
12 miles = 55 miles per hour * Time
.
You can then solve for the Time by dividing both sides of this equation by 55 to get:
.
12/55 = Time
.
So it takes 12/55 hours to go 12 miles. The fraction 12/55 converts to a decimal by dividing
55 into 12 to get 0.218181818 of an hour. Since an hour has 60 minutes, you can convert
the answer to minutes by multiplying 60 by 0.218181818 to get about 13.09 minutes.

Step-by-step explanation:
6(x−6)=5(x+1)
Step 1 - Expand the brackets:
6(x - 6) = 5(x + 1)
6x - 36 = 5x + 5
Step 2 - Add 36 to both sides of the equation:
6x - 36 + 36 = 5x + 5 + 36
6x = 5x + 41
Step 3 - Subtract 5x from both sides of the equation:
6x - 5x = 5x + 41 - 5x
x = 41

Answer:

Step-by-step explanation:
The dilation of triangle QRS is stretched by scale factor 1/2.5.
From the Figure,
The coordinates of S(-1, 0), R(-1, 1) and Q(2, 0)
and, the coordinates of S' (-2.5, 0), R'(-2.5, 2.5) and Q'(5, 0).
Now, the scale factor is
= side of QRS / side of Q'R'S'
As, side of QR = 3 unit and side of Q'R' = 7.5 unit.
So, the scale factor is
= 3 /7.5
= 1 / 2.5
Thus, the dilation is stretched by scale factor 1/2.5.

Compute the following sum of a geometric sequence: S = 0.936 + 0.935 + ... + 0.92 + 0.9 + 1 (Round your answer to two decimal places.)
Answers
The sum of the given geometric sequence to 2 dp is 936.00
To get the sum of a geometric sequence, we will use the formula for calculating the sum to infinity of the sequence as shown:
[tex]S_\infty=\frac{1}{1-r}[/tex]
a is the first term
r is the common ratio
Given the sequence S = 0.936 + 0.935 + ... + 0.92 + 0.9 + 1
a = 0.936
r = 0.935/0.936 = 0.998
Substitute into the formula
[tex]S_\infty=\frac{0.936}{1-0.999}\\S_\infty=\frac{0.936}{0.001}\\S_\infty=936[/tex]
Hence the sum of the given geometric sequence to 2 dp is 936.00
