A) Rate of change is 0.208
Rate of change is change in Y divided by the change in X. Let Y be the Dosage. Let X be the Weight.
Subtract first dosage from the second:
7.5 - 5 =2.5

Subtract the first weight from the second:
36 - 24 = 12

Now divide:
2.5 ÷ 12 = 0.208

b) It is linear. Instead of subtracting the first from the second, just subtract the second from third:
10 - 7.5 = 2.5
48 - 36 = 12

Or the third from the fourth
12.5 - 10 = 2.5
60 - 48 = 12

Or the fourth from the fifth
15 - 12-5 = 2.5
72 - 60 = 12

What do you notice? You get 2.5 and 12 for all of them, thus the relationship is linear.

The difference between a number divided by 3 and 4 is 20
Rzqust [24]
Set the number to x.

\frac{x}{3}-\frac{x}{4}=20
\frac{4x}{12}-\frac{3x}{12}=20
\frac{x}{12}=20
x=240

Thus, the number is 240.

What are the coordinates of the inflection point on the graph of y=(x+1)arctanx
Dennis_Churaev [7]

Inflection point is the point where the second derivative of a graph is zero.

y = (x+1)arctan xy' = (x+1)(arctan x)' + (1)arctan xy' = (x+1)/(x^2+1) + arctan xy'' = (x+1)(1/(1+x^2))' + 1/(1+x^2) + 1/(1+x^2)y'' = (x+1)(-1/(1+x^2)^2)(2x)+2/(1+x^2)y'' = ((x+1)(-2x)+1+x^2)/(1+x^2)^2y'' = (-2x^2-2x+2+2x^2)/(1+x^2)^2y'' = (-2x+2)/(1+x^2)^2

Solving for point of inflection: y'' = 00 = (-2x+2)/(1+x^2)^20 = -2x+2x = 1y(1) = (1+1)arctan(1) = 2 * pi/4 = pi/2

Therefore, E(1, pi/2).
