Right format of question:
Plot two points that are 7 units from Point D and also share the same x-coordinate as Point D.
Answer:
and 
Step-by-step explanation:
Given
Required
Determine a point 7 points from D and in the same x coordinate
Represent this point with D'.
From the requirement of the question, D' has two possible values and these values are:
----> 7 units down and
----> 7 units up
Substitute values for x and y in and
So, we have:
Take the vector u = <ux, uy> = <4, 3>.
Find the magnitude of u:
||u|| = sqrt[ (ux)^2 + (uy)^2]
||u|| = sqrt[ 4^2 + 3^2 ]
||u|| = sqrt[ 16 + 9 ]
||u|| = sqrt[ 25 ]
||u|| = 5
To find the unit vector in the direction of u, and also with the same sign, just divide each coordinate of u by ||u||. So the vector you are looking for is
u/||u||
u * (1/||u||)
= <4, 3> * (1/5)
= <4/5, 3/5>
and there it is.
Writing it in component form:
= (4/5) * i + (3/5) * j
I hope this helps. =)
Answer:
Step-by-step explanation:
Let us represent:
Apple pie = a
Cherry pie = c
Peach pie = p
A bakery has three types of pie: apple, cherry, and peach.
There are four times as many apple pies as peach pies.
a = 4p
