Answer:

Step-by-step explanation:

1) √2 + 2√2 =  ( 1 + 2 ) √2 = 3*√2   = 3√2

4) √8 + √2 = √2*2*2 + √2 = 2√2 + √2 = ( 2 +1 ) √2 = 3√2

7) 2√5 - √5 = (2 - 1)√5 = 1 √5

10 3√5 - 2√5 = (3 - 2) √5 = 1√5

Consider the function, f(x) = 3x - 3. Determine the asymptote for the function f(x).
Natali [406]

Answer:

Y= 1

Step-by-step explanation:

Given the expression f(x) = 3x - 3.

To solve for the asymptote y

Firstly we need to solve for x

3x-3=0

3x=3

x= 3/3

x=1

Hence the asymptote of the function y=1

Find a b if a = 3i + 8j and b = -0.5i -4j.
Gekata [30.6K]

Answer:

-33.5

Step-by-step explanation:

So this is a dot products vector problem, so the i and j represent x and y or horizontal and vertical components. So you multiple 3i and -0.5i and then separately multiply 8j and -4j. You get -1.5 and -32. Now all you have to do is add them and you get -33.5.

Basically in short:

1. Multiply the “i’s”.

2. Multiply the “j’s”.

3. Add the two products together.

HOPE THIS HELPS !! :-)
