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
I think the best way is to use a computer drawing program in constructing a regular hexagon inscribed in a circle. Its because a computer program is an accurate, precise and the most important it is more efficient than using the straight edge and compass
Answer:
W = 7
Step-by-step explanation:
1) Simplify 21/42 into 1/2
w/ 14 = 1/2
2) Multiply both sides by 14.
W = 1/2 · 14
3) Simplify
W = 14/29
4) Simplify (again)
W = 7
A+(n-1)d=nth term
a----first term(260)
d----common difference(-52)
Hope it helps!!
