Answer & Explanation:
To find the direction cosines of the vector a is need to divided the corresponding coordinate of vector by the length of the vector. The coordinates of the unit vector is equal to its direction cosines. Property of direction cosines. The sum of the squares of the direction cosines is equal to one.
The answer to your question is 4
Answer:
_____________________
a(6,-7) m(7,-5) letb(p,q)
Now,
Let a(6,-7) be x1 ,y1
Let b(p,q) be x2,y2
x,y = (7,-5)
Using Mid point Formula,
x = x1+x2 y= y1+y2
_____ , _____
2 2
7 = 6+p -5 = -7+q
___ , ____
2 2
or, 7×2=6+p , -5×2= -7+q
or, 14=6+p , -10= -7+q
or, p=14-6 , q= -7+10
p=8 , q= 3
Step-by-step explanation:
So , The coordinate of B(8,3)
Thank you
Answer:
29
Step-by-step explanation:
Because if it was 5 or higher in front round up to 30 but because it's lower than 5 it's still 29.
Answer:
2/5 of the cake
Step-by-step explanation:
First, find how much she gave away:
2/5 + 1/5
= 3/5
Then, to find how much she has left, subtract 3/5 from 1
1 - 3/5
= 2/5
So, she has 2/5 of the cake left for herself
