Answer:
f(4) = 85 1/3 or 85.333...
Step-by-step explanation:
To find f(4), you must substitute 4 in place of x whenever x appears:
f(x) =
*
f(4) =
* 
Next, simplify the exponent:
f(4) =
* 256
Finally, multiply:
f(4) = 85 1/3 or 85.333...
Answer: 2%
Step-by-step explanation:
1600/80000. Simplifying by 100:
16/800. Simplifying by 8, comes to:
2/100 = 2%
Answer:
Perpendicular
Step-by-step explanation:
Put all the points on a graph.
Parallel means that the lines that have the same slope and different y-intercepts. Lines that are parallel to each other will never intersect.
On the graph we made we can see that the lines will have to intersect because the points are in positions that no matter which points we chose to connect together, they would intersect with the other line.
Answer:
m = 
Step-by-step explanation:
Given
=
( cross- multiply )
6m = 21 ( divide both sides by 6 )
m =
=
( = 3.5 in decimal form )
1/8=.125, so 12 and a half % are blue
