Answer:

-10 + 2i

Yes, it is imaginary

Step-by-step explanation:

(-2+4i) - (8+2i) \\  \\  =  - 2 + 4i - 8 - 2i \\  \\   =  - 2 - 8 + 4i - 2i \\  \\  =  - 10 + 2i

P=4.50s is the equation to use to determine p ...
because i believe y=mx+c 

in this case
y is the price (p)
m is 4.50
x is the number of sunglasses (s)
there is no constant (c)

so p=4.50s

Vector A⃗ has magnitude 5.1 m and points to the right; vector B⃗ has magnitude 4.0 m and points vertically upward. What is the m
Doss [256]

The magnitude of the vector C that satisfies the expression is 6.48m

Given the following magnitude;

Vector A = 5.1m

Vector B = 4.0m (upward)

Taking the resultant vector of A and B we will have:

R=\sqrt{A^2+B^2}\\R=\sqrt{5.1^2+4.0^2}\\R=  \sqrt{26.01+16}\\R=\sqrt{42.01}\\R=  6.48m

Given the expression A⃗ +B⃗ +C⃗ =0⃗

R + C = 0

C = 0 - R

C = 0 - 6.48

C = -6.48m

Hence the magnitude of the vector C that satisfies the expression is 6.48m

Iteru [2.4K]

Answer:

50 mph

Step-by-step explanation:

We have the following point

(2,100)

We know that the equation has a y intercept of 0 which means our equation looks like this

y=mx

We know that when x=2 y=100 so

100=2m

m=50

50 mph
