Answer:
x = 12/7 or 1.7
Step-by-step explanation:
first, cross multiply to get 7x = 12. then, divide 12 by 7 to get 12/7, which can be simplified and rounded to 1.7.
Answer:
complementary angles
Step-by-step explanation:
Adjacent angles form a right angle.
A right angle is 90 degrees.
Two angles that add to 90 degrees are complementary.
The adjacent angles are complementary
The answer is,
Also equivalent to about, 0.185188.
Step-by-step explanation:
Knowing the power rule:
dx*n*x^(n-1) all you'd need to do is bring the 7 down and multiply it by -3, then subtract 1 from 7. Because dx is 1 you don't need to worry about it (you'll use chain rule for that)
So your final answer should be dy/dx= -21x^6
