A 100-gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The function f (x) = StartFraction 100 Over x EndFraction represents the remaining time in minutes needed to fill the tank. How is the graph of the parent function f (x) = StartFraction 1 Over x EndFraction transformed to create the graph of the function On a coordinate plane, 2 curves have an asymptote at x = negative 20. One a curve opens up and to the right and goes through (Negative 15, 20) and (0, 5). Another curve opens down and to the left and goes through (negative 40, negative 5) and (negative 25, negative 20).?

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

i think 1: 2

step-by-step explanation:

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
