If I’m not mistaken he wrote from 12 to 111 correct? If so the answer would be 99
Answer:
The required vectors are 
and 
.
Step-by-step explanation:
Given information: P(-4,-2) and Q(3,-4).
We need to find the two vectors parallel to 
with length 2.
If 
and 
, then
Using the above formula we get
vector QP is,
Magnitude of vertor QP is,
Using vector is
Multiply vector w by 2 to get a parallel vector parallel of QP in same direction.
Multiply vector w by -2 to get a parallel vector parallel of QP in opposite direction.
Therefore the required vectors are and .
Answer:
The equation of the parallel line would be y = -1/2x + 1
Step-by-step explanation:
To start we need to find the slope of the original line. We can do that by solving for y.
x + 2y = -4
2y = -x - 4
y = -1/2x - 2
Since the slope of the original line is -1/2 and parallel lines have the same slope, we know the new line will also have -1/2 slope. Now we can use that along with the point given in point-slope form to get the find equation.
y - y1 = m(x - x1)
y - 5 = -1/2(x + 8)
y - 5 = -1/2x - 4
y = -1/2x + 1
Answer:
Statement B, C, E are correct
<u>Solution:</u>
We have to find the true statements
We know that,
To find the diameter of a circle, multiply its radius by two
Thus statement E is correct
Also,
To find the diameter of a circle, divide its circumference by π
Thus statement B is correct
circumference of a circle is obtained by multiplying diameter with pi
The circumference of a circle is greater than its diameter
Thus, Statement C is correct
