Step-by-step explanation:
I take it this is meant to be a multiplication, right ?
not a "function of function", which would be symbolized by a little empty circle.
to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.
(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =
= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =
= -2x⁴ - 32x³ - 82x² + 308x
The slope of any line is the fraction 
, where 
is the change in y-coordinate and 
is the change in x-coordinate.
To find these changes, we take the <em>difference </em>of the corresponding x and y coordinate for the two points. Here, our y-coordinates are -7 and 3, and our x-coordinates are 5 and 1, so our slope is
The answer would be 0.13658537...
but when you estimate it the answer would be 0.14
Answer:
B and D
Step-by-step explanation:
Speed = distance / time
his travel speed TO the meeting.....
s = 480 / 8 = 60 miles per hr
his travel speed FROM the meeting...
s = 480 / 7.5 = 64 miles per hr
