Answer:
Step-by-step explanation:
We are given that
Radius of end of a log, r= 9 in
Error, in
We have to find the error in computing the area of the end of the log by using differential.
Area of end of the log, A=
Now,
Approximate error in area
Using the values
Hence, the possible propagated error in computing the area of the end of the log
The first or second one because a function can't have the x value repeating
Answer:
Option C is correct that is the x-coordinate of the center of the circle increases by 3.
Step-by-step explanation:
The given equation is:
Since, the circle is shifted right 3 units
There, will be no change in y-axis because it is horizontal change.
So, Option A,B and D are discarded.
Therefore, Option C is correct that is the x-coordinate of the center of the circle increases by 3.
Y-intercept is 3 or (0, 3)
X-intercepts are - 1, 3 or (- 1, 0) and (3, 0)
Answer:
b. BC
Step-by-step explanation:
The first thing is to calculate the dimensions of each matrix, that is, the number of rows x number of columns:
dimensions of A: 2x2
B dimensions: 2x3
C dimensions: 3x3
D dimensions: 1x3
We have that a matrix multiplication is defined, the internal numbers of its dimensions must be the same: we analyze each option:
BA: (2x3) * (2x2): the internal numbers do not match (a 3 for B and a 2 for A), so the multiplication of the matrix is not defined
BC: (2x3) * (3x3): the internal numbers are both 3, so the matrix multiplication is defined
CB: (3x3
) * (2x3): the internal numbers do not match (a 3 for C and a 2 for B), so the multiplication of the matrix is not defined
CD: (3x3) * (1x3): the internal numbers do not match (a 3 for C and a 1 for D) so the multiplication of the matrix is not defined
Therefore the answer is b. BC
