Answer:
-3,-1,0,5,7
Step-by-step explanation:
We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd
Answer:
That is 6 divided by 3/8, better written as
6
--
1
====
3
--
8
Invert the 3/8 and then multiply:
6 8
-- * ---
1 3
Reduce 6/3: 6/3 = 2
Then you have 2(8), or 16 (answer)
Consecutive odd integers are 2 apart
they 2 numbers are
n and n+2
their product is 99
n times n+2=99
n(n+2)=99
n²+2n=99
minus 99 both sides
n²+2n-99=0
what 2 numbres multiply to -99 and add to get 2
if you can't do that
complete square
n²+2n+1-100=0
(n+1)²-100=0
(n+1)²=100
sqrt both sides
n+1=+/-10
n=-1+/-10
n=-11 or 9
if n=-11, then n+2=-9
if n=9 then n+2=11
the integers are -11 and -9 or 9 and 11
