Answer:
- <43, -30>
- <-1, 6>
Step-by-step explanation:
The answer is found by carrying out the indicated arithmetic. Multiplying a vector by a scalar multiplies each of the vector's components. Adding vectors adds corresponding components.
<u>Question 1</u>
3u -5v = 3<11, -5> -5<-2, 3>
= <3·11 -5(-2), 3(-5) -5(3)>
= <33 +10, -15 -15>
= <43 -30>
<u>Question 2</u>
m - n = <0, 0> -<1, -6>
= <0 -1, 0 -(-6)>
= <-1, 6>
Answer:
Equation has to have a plus, minus, etc. and an inequality is used to make the equation equal
Step-by-step explanation:
So your question was not very clear but with (f+g) im guessing thats f(x)+g(x)
So first we add them x^2+4x-32 + x-4 then we will get x^2 + 5x - 36
Then we need to multiply both
(x^2+5x-36)(x^2+5x-36)
=
(x^2+5x-36)^2
The only reason im not solving it out is because it yields large numbers and you might not understand.
S is stocks and b is bonds
s + b = 28800
3b = 5s or s = 3/5 b
substitute in for s
3/5 b + b = 28800
3b + 5b = 144000
8b = 144000
b = 18000 amt in bonds
s + 18000 = 28800
s = 10800 amt in stocks
