Step-by-step explanation:
a) We can find the iterative rule by first making a table of values.
n ->
1 -> 22
2 -> 28
3 -> 34
We see that increases by 6 each time. Hence, the iterative rule should have the term 6n. However, if we put 1 in for n, we get 6. We want 22-6=16 more than this, or . This would work for any seat row we give.
b) Our iterative rule to get the number of seats is . Since we know that this value is 100, we can put both equal to each other.
Thus, the 14th row has 100 seats.
Given that:
The triangle ABC and its image are shown below.
Step-by-step explanation:
In the below figure triangle A'B'C' is the image of triangle ABC.
We need to sketch a possible line that triangle ABC could translate along to create its image.
So, connect the corresponding vertices. So, the required lines are AA', BB' and CC '.
In translation, each point of the figure is shifted from point to another point in a particular distance and direction.
Point A, B and C are shifted to A' B' and C' respectively. So AA', BB' and CC' represents the distance and direction of translation.
From the figure it is clear that triangle ABC shifted 10 units right and 6 units down.
Answer:
Area_circle = pi*13^2 = ~530.29
Area_sector = pi*13^2* 315/360 = ~464.56
M = (y2 - y1)/(x2 - x1)
m = (-1 - 1)/(-2 + 4)
m = -1
Answer:
16
