Evaluate the expression:

v ⋅ w

Given the vectors:

r = (8, 8, -6); v = (3, -8, -3); w = (-4, -2, -6)

Answers

Answer 1

Answer:

vw= 22

Step-by-step explanation:

To find the dot product of vw, multiply the corresponding numbers and add them.

v= <3, -8, -3> w= <-4, -2, -6>

vw= (3*-4)+(-8*-2)+(-3*-6)

vw= -12+16+18

vw= 4+18

vw= 22

If f(x) = -х3, g(x) = 3х2 – 1, and hx) = 2х + 5, what is the degree of [f ogo h](x)?
2
3

6

Answers

Answer:

D my love :  6

Find f(g(h(x))).

h(x)=2x+5

g(h(x)) = 3(2x+5)^2 -1     (substitute h(x) in)

f(g(h(x)))= -[3(2x+5)^2 -1]^3    (substitute g(h(x)) in)

Since it asks for the degree of the function, that means we must look for the variable with the highest degree. In this case, after distributing and simplifying out the last equation, we will find that the variable x has the highest degree of x^6, or 6.
