Answer:
<u>the order in which the ratio is drawn should be the same as listed.</u>
Explanation:
What this means is that since a ratio compares the sizes of two numbers (eg 4:2 or 4 ratios 2 or ), it would be wrong to change the order of a ratio when drawn in a diagram.
For example, changing the order to (2:4 or 2 ratios 4), which then because not
. Hence, it is important to remember that diagram of the ratio of two or more quantities should be the same as listed.
Answer:
(14/3, 8/3)
Step-by-step explanation:
Let the points be
The formula for finding the coordinates of point that divides the line in a:b is:
Here x and y are the coordinates of the point that will partition the line into given ratios
Our ratio is 2 to 1,
So,
a=2
b=1
Putting the values in the formula
So the coordinates of point that divides AB in 2:1 are:
(14/3, 8/3) ..
Answer:
41
Step-by-step explanation:
We know that complex numbers are a combination of real and imaginary numbers
Real part is x and imaginary part y is multiplied by i, square root of -1
Modulus of x+iy =
Here instead of x and y are given 9 and 40
i.e. 9+40i
Hence to find modulus we square the coefficients add them and then find square root
|9+49i| =
By long division method we find that
|9+40i| =41
