They both have a y and x axis and they both represent things
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: $30 charge for the helmet before tax
Step-by-step explanation:
Let P the pre-tax subtotal
Sales tax = P·5/100
Since we know the sales tax paid, we can substitute its value here:
P·5/100 = $1.50
P = $1.50·100/5 = $150/5 = $30 , charge for the helmet before tax
Answer: $30 charge for the helmet before tax

Answer:
The arc length of the semicircle is: , which is approximately 34.5575
Step-by-step explanation:
Recall that the length of a circumference of radius R is given by:
therefore, the arc length of a semicircle (half of the circle) would be given by half of the previous expression:
So, in our particular case of radius 11, the formula for the arc length of the semicircle becomes:
