Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
Answer:
~ 83.90
2 decimal place is basically the hundredths place
Answer:
2
Step-by-step explanation:
amplitude = distance from undisturbed position/centre line to trough or peak
i think your answer stays the same hun, because you dont give any way on how to solve it. Sorry pumkin!
-10=5(2x-4)
-10=10x-20
+20 +20
10=10x
1=x
