If mike gets paid today , than mike with go to the bank . Mike did not get paid today .

Bumek [7]

Remark
The problem with A and B is that one or the other is always possible. So one of them should be your answer.

Comment
This problem depends on whether or not you believe the two statements are connected in some way.

Does he go to the bank to deposit money, or is that the only time he can go to the bank is on the days that he gets paid?

The problem is not clear enough to make a decision. So your answer is either B or D.

I would say your safest choice is D. You don't know for certain what his motivations are.

What is the result when the number 39 is decreased by 3%?

dlinn [17]

Answer:

New value =

39 - Percentage decrease =

39 - (3% × 39) =

39 - 3% × 39 =

(1 - 3%) × 39 =

(100% - 3%) × 39 =

97% × 39 =

97 ÷ 100 × 39 =

97 × 39 ÷ 100 =

3,783 ÷ 100 =

37.83

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f (x )equalsStartFraction x

ankoles [38]

Answer:

The rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities are:

a) 0.52

b) 2.63

Step-by-step explanation:

The rate of change of a function at a given point P can be obtained by evaluating the 1st derivative of the function in P. Thus,

$f(x)=\frac{x^2}{2(1-x)}$

$\frac{df(x)}{dx} = \frac{d(\frac{x^2}{2(1-x)})}{dx} \\\frac{df(x)}{dx} =\frac{x}{1-x} + \frac{x^2}{2(1-x)^2} \\\frac{df(x)}{dx} = -\frac{x(x-2)}{2(x-1)^2}$

Now for we just need to evaluate in each of the given points

a) $\frac{df(0.3)}{dx} =-\frac{0.3(0.3-2)}{2(0.3-1)^2}\\\boxed{\frac{df(0.3)}{dx} =0.520408 \approx 0.52}$

b) $\frac{df(0.6)}{dx} =-\frac{0.6(0.6-2)}{2(0.6-1)^2}\\\boxed{\frac{df(0.6)}{dx} = 2.625\approx 2.63}$
