Answer:
B. 31
Step-by-step explanation:
The acreage Mr. Flowers intends to sell is 2/3 of his total, so is ...
(2/3)(23 1/4) = (2/3)(93/4) = 31/2 . . . . acres
Divided by 1/2 (which is the size of a lot), we will get the number of lots this will make:
(31/2)/(1/2) = 31/1 = 31
Mr. Flowers will have 31 lots for sale.
Hence, the scalar projection of onto = , and the vector projection of onto = .
We have given two points and .
Let, and .
and we have calculate the projection of onto .
Now,
For the calculation of projection, first we need to calculate the dot product of and .
then, we have to calculate the magnitude of .
= = = .
Now, the scalar projection of onto =
=
and the vector projection of onto =
