A: 2/1 -> 2
B: -1/1 -> -1
Gradient or slope is the change in the y value/change in the x value
Y value is up and down and x value is side to side.
Hope this helps! :)
Answer:
number B (4×4)+(3×3×3)= 43
Answer:
r=3 where r is the common ratio
Step-by-step explanation:
The sum of geometric progression for n terms is given by:
, where is the
first term of the series and r is the common ratio.
Now, according to the question, there are four terms and they form a geometric progression. So sum of four terms is given as and .
Also according to the above formula:
Using the values as given in the question into the above equation we get:
[ Using formula ]
which is the required answer.
Answer:
a) you need to plot a cross on the graph (with the pencil) in the right place:
(x-axis: 4, y-axis: 2600)
b) the older the car is, the lower its value. there is a negative correlation between the cars age and its value.
c) you need to draw a line of best fit on the graph. where the line is at 3 1/2 years, that is its estimated value. (my guess is around £3000)
