When n = 1, m = -5.5, when n = 2, m = -8.5, when n = 3, m = -11
Answer:

Step-by-step explanation:
let the diagonal be d
using the pythagoras theorem,


which in radical form is

-20 to -14 is 6
-14 to -8 is 6
-8 to -2 is 6
aritmetic sequence
an=a1+d(n-1)
a1=first term
d=common difference
n=which term
first term is -20
common difference is 6
we want 50th term
a50=-20+6(50-1)
a50=-20+6(49)
a50=-20+294
a50=274
the 50th term is 274
Answer:
It is x2 -4 because it correct
Answer:
Step-by-step explanation:
angular frequency
ω = 2π/ T = 2π/4 = π/2 rad/s
A = 7 inch
Starts at rest (maximum swing, |A| = 7) so cosine function is easiest
x = -7cos(πt/2)
