Answer:
v = 120
Step-by-step explanation:
If v is inversely proportional to square root of d, then we can write
= k
If v = 30 and d = 400, then
30() = k
k = 30(20) = 600
Now = 600
If d = 25, then v = 600
5v = 600
v = 120
Answer:
The rate of change is zero
Step-by-step explanation:
When drawn on graph paper, the 2 points are horizontal (they have the same y-value). When plugging in values in the slope formula, (y2-y1)/(x2-x1) you will get 0/4, which is still zero.
Is it equal to 50% because 2/4 is .5 and to make a fraction you move the decimal over two places to the right<span />
