A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
Answer:
TOO SMALL I CanT SEE THE QUESTION!!
Step-by-step explanation:
1a. You can't do much for it, answer could be x(x+8)
1b. (x+5)(x+3)
1c. (x + 3y)(x - 3y)
1d. (5x - 4) (x + 2)
2. It's very likely you need a protractor and a ruler for this. If not, tell me and I'll try to find it.
Answer:
y = 8x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = 5
y = 8x + 5 ← equation of line
