It would depend on what n was equal to
We would simplify each bracket.
For the first bracket,
2 + 4 = 6
For the second bracket, 8 * 1000 = 8000
For the third bracket, 700/5 = 140
The expression becomes
6*8000*140 = 6720000
270.7608 to nearest whole number is 271
Hope it helped!
For this case we have the following vectors:
a = 3i + 8j
b = -0.5i - 4j
Using product point we have:
a.b = (3i + 8j). (- 0.5i - 4j)
a.b = (3) * (- 0.5) + (8) * (- 4)
a.b = -1.5 + -32
a.b = -33.5
Answer:
The point product is given by:
a.b = -33.5
B. -33.5
