Answer:
x = 1/3
Step-by-step explanation:
Hello,
we can draw the two lines defined by
y = 4 - x
y = 2x + 3
And search for the intersection point as below
This is the point A (1/3, 11/3)
Do not hesitate if you have any question
Thanks
7 units bc I took the test already
Answer:
for the first 2 neither one is a polygon because a polygon has straight sides and is closed connections were the first shape has an open connection and the second shape has a curved line. for question i believe is 48 and question 4 is 145.
explanation.
for the last 2 problems their total equal 360 so you just add up all the side then subtract the number you got by 360 and that's your answer. ex.) 120 +130+ 62=312. 360-312=48
Mohamed decided to track the number of leaves on the tree in his backyard each year. the first year, there were 500 leaves. each year thereafter, the number of leaves was 40% more than the year before. let f(n) be the number of leaves on the tree in Mohamed's backyard in the n^th year since he started tracking it. f is a sequence. what kind of sequence is it?
Number of leaves on the tree in first year = 500
The number of leaves was 40% more than the year before.
So rate of increase is 40/100 = 0.4
We use exponential growth formula,
f(n) = a(1+r)^n
Where a is the initial number, r is the rate of growth, n is the number of years
We know a= 500, r= 0.4
f(n) = 500(1+0.4)^n
f(n) = 500(1.4)^n
Plug in n=1,2,3...
f(1) = 500
f(2) = 500 * 1.4^1
f(3) = 500 * 1.4^2 and so on
From this we can see that the common ratio is 1.4
Hence it is a Geometric sequence.
