What is x?
7.5/12 = 4.2/x
6.72
Answer:
x = ±
Step-by-step explanation:
5x² - 3y = 4y + 8 ( add 3y to both sides )
5x² = 7y + 8 ( divide both sides by 5 )
x² = ( take square root of both sides )
x = ±
Answer:
4i+j-2k
Step-by-step explanation:
The missing figure in this problem as been attached, as we can see the figure is a 3-D figure consisting of rods with point C and B.
Using the figure we can find the value of position vector
r=-
As we know , a position vector is the difference of position vector of ending point to the position vector of starting point, here the starting point is C and ending point is B. Hence, the expression above.
We need to first find and
Using the figure:
=0i+4j+2k
= -4i+3j+4k
r=-=(0i+4j+2k) - (-4i+3j+4k)
r=4i+j-2k (feet)
