Refer to the diagram below
The shape ABCD first is reflected on the mirror line y = x
Then it is reflected again on the y-axis [equation of the line is x = 0]
To solve this problem you must apply the proccedure shown below;
1. You have the following exponential equation given in the problem above:
3.2+e^(6x)=54.2
2. You must solve for e, as following:
e^(6x)=54.2-3-2
e^(6x)=51
3. By applying ln, you obtain:
ln(e)^(6x)=ln(51)
6x=ln(51)
x=ln(51)/6
x=0.65
Therefore, the answer is: x=0.65
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)
