Answer: There is a linear relationship between the average price of PCs and the number of years that have passed since 2000.
Step-by-step explanation:
From the given graph, we can see there is a straight line , which shows that there is a linear relationship between both quantities.
As the number years increases the average price of PCs decreases.
The given equation of the line is 
, which shows that the slope of the line is -39, i.e the rate of decrease in the average price of PCs with respect to the the number of years that have passed since 2000.
Answer:
The center of the circle is (13.4, - 2.6).
Step-by-step explanation:
Circle:
- The diameter of a circle is 2 times of its radius.
- The area of a circle is
, where is the radius of the circle.
- The circumference of a circle is
, where r is radius of the circle.
We know that,the equation of circle is in the form
where 
is the center of the circle and r is the radius of the circle.
Given equation of circle is
The center of the circle is (13.4, - 2.6).
The radius of the given circle is 
units=10 units.
Answer:
63 m
Step-by-step explanation:
We know the rate in 45 m / min
We need to change the time to min
1 min 24 sec
We know that 1 min = 60 sec so 24 seconds is 24/60 ths of a minute
1 min 24/60 min
1 2/5 min
Changing to decimal form
1.4 minutes
Now we multiply by the rate to get the distance
d = r *t
d = 45 m/ min * 1.4 min
d= 63 m
True multiply both sides by 15
Answer:
<em>Answer: B. 38 mm</em>
Step-by-step explanation:
<u>The Perimeter of a Shape</u>
The perimeter of a given shape is the sum of all exterior lengths surrounding the shape.
The figure shows a shape where all the external measures are given except the leftmost side.
This length is the sum of 3 mm + 10 mm = 13 mm.
Now calculate the perimeter:
P = 4 mm + 3 mm + 10 mm + 8 mm + 13 mm = 38 mm
Answer: B. 38 mm
