evaluate the expression.

r = < 7, -3, -7> , v = < 4, 6, -5> , w = < -5, -6, -3>

v ⋅ w

a) -41
b) < -20, -36, 15>
c) < -28, 18, -35>
d) -9

v . w = <-20, -36, 15>

Step-by-step explanation:

r = <7, -3, -7>, v = <4, 6, -5>, w = <-5, -6, -3>

To find the dot product of vectors we multiply the numbers

We need to multiply v  and w

vectors is in the form of <x,y,z>

Multiply all the x values

4 times -5= -20

6 times -6 = -36

-5 times -3 = 15

So v . w = <-20, -36, 15>

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
