Answer:
Part 1)
Projection of vector A on vector B equals 19 units
Part 2)
Projection of vector B' on vector A' equals 35 units
Step-by-step explanation:
For 2 vectors A and B the projection of A on B is given by the vector dot product of vector A and B
Given
Similarly vector B is written as
Thus the vector dot product of the 2 vectors is obtained as
Part 2)
Given vector A' as
Similarly vector B' is written as
Thus the vector dot product of the 2 vectors is obtained as
The answer is A. 10C5(2a)^5(-3b)^5
Answer:
Okay I’m confused because there is no decimals in the answer, but the answer is 825. I guess you can put 825.00 if you want.
Step-by-step explanation:
Multiply 0.825 and 1000 together to get the answer
Firstly try to find the number between 100 and 400 which are actually divisible by 13 so
104,117,130………. 390
If you see the above arrangement the difference between numbers are common so we can apply arithmetic progression.
By arithmetic progression, last term can be denoted by
l= a+(n-1)d
Where l=390
a=104
d=13
n=?
390=104+(n-1)13
13n=286+13
n= 299/13
n= 23
So total number of terms =23
By using arithmetic progression sum of all A.P terms = (n/2)(a+l)
Sum = (23/2)(104+390)
=(23/2)*(494)
= 5,681
So answers is 5,681.
Answer:
x = √324 = 18
Step-by-step explanation:
x shows up only in the second problem, so I'll focus on that problem.
This is a right triangle because one of the three angles is 90 degrees.
Thus, the Pythagorean Theorem applies: x^2 + 24^2 = 30^2, or
x^2 = 900 - 576 = 324
Then x = √324 = 18
