Answer:
The slope of the line reflects the actual trend of the data
Step-by-step explanation:
<u><em>The options of the question are</em></u>
a. The slope should be negative.
b. The spacing for each axis must be chosen so that the line reflects a positive slope.
c. The slope of the line reflects the actual trend of the data.
d. The slope of a line is not important in analyzing a line graph
we know that
The slope of a line is the steepness of the line ( the change in 'y' over the change in 'x',)
The formula to calculate the slope between two points is equal to
where
---> is called the rise
is called the run
Is important because the slope of the line reflects the actual trend of the data
Answer: Every year, the value of an antique vase appreciates by 20% of its value in the previous year. If the value of the vase was $180 000 in 2012, its value in 2010 was $125000
Step-by-step explanation:
Given the appreciation rate r, the initial value I, the final value V, and the period of appreciation n, the formula for appreciation is given by:
V = I(1 + r)ⁿ
In our case, we need to work out the value of n.
We do this as follows:
n =2012 - 2010 = 2 years
Substituting the values we have:
180000 = I(1.20)²
180000 = 1.44I
I = 180000/1.44
= 125000
So, in 2010, the value of the vase was $125000

Answer:
Both 4x^2 and 64 are perfect squares
Step-by-step explanation:
If you are looking for the difference of squares, the two terms both have to be squares. We know that 64 is a square because it is 8 x 8. Also, we can say 4x^2 is a square because it can also be written as (2x)^2. We are basically looking for an option that tells us that they are square. This is option 1.
The second option is invalid because being an even number does not mean the number is a square.
The third option does not help the case much either. Just because there is a common perfect square factor, does not mean the numbers themselves are perfects squares.
