So another way to look at is 7x6=__ and so when you do this you get 42. Hope this is helpful.
Looking at the graph, trace your finger up from 10 on the x-axis. You will end up somewhere around 17.
Therefore, the approximate height of the tree after 10 years will be 17 feet.
the answer would be A.) C+15
Two complementary angles must add to 90 degrees, and if you divide 90 into thirds (two parts for the larger angle, one for the smaller), then you get 30 degrees.
If the smaller angle is 30 degrees, then the larger is two times that, which is 60. 60 + 30 = 90, so the larger angle is equal to 60 degrees.
Answer:
2i²+5ij+3ik-12j²-10jk-2k²
Step-by-step explanation:
a=2i-3j-k
b=i+4j+2k
ab = (2i-3j-k) (i+4j+2k)
Multiply both bracket by expanding the bracket
2i(i+4j+2k)-3j(i+4j+2k)-k(i+4j+2k)
Multiply
2i²+8ij+4ik-3ij-12j²-6jk-ik-4jk-2k²
Collect like terms
2i²+8ij-3ij+4ik-ik-12j²-6jk-4jk-2k²
2i²+5ij+3ik-12j²-10jk-2k²
