The answer is C. First, the area of the plot should be the multiplication of the two side lengths, so 11.7 * 15.4=180.18. However, we have to look at the significant digits to decide to what digit should we round the answer to. Since both 11.7 and 15.4 are accurate to the tenths digit, 180.18 should also be so, so we should round it to 180.2.
Answer:
your answer is A or b
Step-by-step explanation:
The vector v is given by:
v = (7, 2) - (-5, 0)
v = ((7 - (- 5)), (2-0))
v = ((7 + 5), 2)
v = (12, 2)
Then, the angle is given by:
tan (theta) = 2/12
theta = atan (2/12)
theta = 9.46 degrees
Answer:
The direction angle of vector to the nearest tenth of a degree is:
theta = 9.5 degrees
Step-by-step explanation:
#34.
After a dilation of 2 (about the origin), all coordinates will be doubled.
Thus the image is 2 time the original matrix, or
-6 -4 -1
8 2 10
#37
a12 means the element on the first row, and the second element from the left.
The question does not indicate which matrix is named "a", but by elimination, we will assume it is the first matrix in the matrix equation.
Isolating the elements 12 (first row, second element) in the equation, we get
a12+5 = 1
which tells us that
a12=1-5 = -4
