Last limits problem for today. I think it's mostly right but something isn't quite right here.

If each years cumulate an increase of 1100 dollars, then the cost after 22 years will be the base cost (27000) plus 22 increases (22*1100), for a total of
This relates to arithmetic series as follows: a series is arithmetic if, given a starting element , every next element is given by adding a fixed number, called common difference,
. So, the first terms are
So, you can see that the element is obtained by adding n times the common ratio to the starting element.
Since the element represents the cost after n years, we are interested in the element
As we had already calculated.
Answer:
8√5 units.
Step-by-step explanation:
See the diagram in the coordinate plane attached.
A rhombus has four equal sides and to find the perimeter of the rhombus we have to measure any of the sides of the figure of the rhombus.
The coordinates of the topmost point are (-1,-1) and that of the rightmost point are (3,-3).
Therefore, side length of the rhombus will be
units.
So, the perimeter of the rhombus will be (4 × 2√5) units = 8√5 units. (Answer)
The distance between two points and
on a coordinate plane is given by
Hey there!
Formula for the area of a circle:
Formula for the radius of a circle:
First, let's divide the diameter by 2 in order to find the radius.
16/2 = 8
Next, we'll plug our values into the formula (found above).
A = pi x 8^2
A = pi x 64
A = 64pi^2 or A = 201.1cm^2
Hope this helps!! :)
