It gives you a few values. The values of f(t) and g(t) when time t=3, and
the values of the rates of change (first derivative) for both at the same time t=3.
f(3) = 8 unit
f ' (3) = 2 unit/s
g(3) = 3 unit
g ' (3) = 8 unit/s
--and also a value of the ratio of the two functions at t=3
Answer:
12x -14y
Step-by-step explanation:
The first truck delivers 12x yds^3 of mulch
The second truck delivers 14y yds^3 of mulch
The difference ( subtraction) is 12x -14y
Answer: y = x+3 which is choice D
-----------------------------------------
Explanation:
This graph goes through (0,3) and (2,5). You can pick any two points on the diagonal line.
Slope:
m = (y2-y1)/(x2-x1)
m = (5-3)/(2-0)
m = 2/2
m = 1
The y intercept is b = 3 as the point (0,3) is on the line
Therefore,
y = mx+b
turns into
y = 1x+3
which is the same as
y = x+3
Note how plugging in something like x = 4 leads to
y = x+3
y = 4+3
y = 7
and we can see on the given graph that (4,7) is a point on the diagonal line. So this helps confirm we have the proper answer
Answer: 10.00 km/l
Step-by-step explanation:
From the question, we are informed that a car travelled 566.48 kilometres on 63.59 litres of gasoline. Based on this information, the number of kilometres per litre the car travelled will be:
= 566.48km/63.59litres
= 8.9kilometres/litres.
This is closest to 10.00 km/l
