Answer:
30°
Step-by-step explanation:
Since the folded paper can fit into the slide three times, we simply have to multiply 10° by 3:
10° * 3 = 30°
The angle of the slide is 30°
Answer:
1) a1 = -5, a(n) = a(n-1) + 2
Step-by-step explanation:
The explicit formula for an arithmetic sequence can be written ...
an = a1 +d(n -1)
The corresponding recursive formula is ...
a(1) = a1, a(n) = a(n -1) +d
__
Comparing the above explicit formula to the one you're given, you see that ...
a1 = -5, d = 2
Using these values in the recursive formula gives you ...
a(1) = -5, a(n) = a(n-1) +2

<span>I can call the points (x1,y1), (x2,y2), and (x3,y3)
Now, plugging in the actual x's and y's
The general form for a quadratic is
Now I can write
(1)
and
(2)
and
(3)
This is 3 equations and
3 unknowns, so it's solvable
Add (1) and (2) to get
Substitute this in (3)
Now substitute and back into (2)
(2)
(2)
Now solve for , then do more substitutions to get and
The solution is
