Answer:
a
Step-by-step explanation:
Answer:
Hmmm let me solve then I will answer
May be you know it or not a two dimensional vector can be represented by a complex number.Why i have written this statement you will just know when you will see its solution
a = 3i + mj and b = 2i - nj are perpendicular to each other ,so their dot product
will be zero.
j
vector b = 2i - nj and vector c = ni + 8j are parallel to each other.
j
mn = 6
so m=6/4i
m=3/2i
m=3i^{4}/2i
m = 3i^{3}/2
m= -3i/2 as(i^{4} =1, i^{3} = -i[/tex][/tex]
Answer:
3.75x + 9/32
Step-by-step explanation:
You start by distributing the 3/4 to both the 5x and 3/8
When you multiply 3/4 by 5x you get 3.75x
When you multiply 3/4 by 3/8 you get 9/32
They are then added together.
Answer:
23
Step-by-step explanation:
The given two triangles are congruent , by SSS congruence condition , therefore the corresponding sides will be equal .
=> x - 4 = 19
=> x = 19 + 4
=> x = 23
