Answer:
Step-by-step explanation:
3.5 miles/(29.4 minutes)
26 miles × (29.4 minutes)/(3.5 miles) = 218.4 minutes
218.4 minutes × (1 hour)/(60 minutes) = 3.64 hours
X = 7 / sin(45)
x = 7 / sqrt(2)/2
x = 7 sqrt(2)
Answer:
-5120
Step-by-step explanation:
Replace the n in the formula by 6.
a6 = -5(4)^(6-1)
= -5 * 4^5
= -5120
1x68
2x34
4x17
Hope that helps
Answer:
We have the equation A*C = A
Now, as both sides of the equality are the same thing, we can do the same operation to both sides and the equality will remain true.
We can divide both sides by A and get:
(A*C)/A = A/A
C = 1
So here we finded the value of A.
If A and C are matrices, then C is the identity matrix.
