yes no
part b
what is wang's new hourly pay rate?
part
carla's pay is $22 per hour. she receives a pay raise of $1 per hour.
did her pay increase by the same percent amount as wang's? explain.

answer:

b

step-by-step explanation:

$1 pay raise = 5% pay raise

Step-by-step explanation:

If you are getting $20 per hour and receives a 5% pay raise... then he is receiving $1 pay raise because 5% of that of you use desmos it has a % which gives u what % it is of it.

so search Desmos in google search and click scientific calculator and if needing for graphing click the graphing instead :)

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
