Since the integral of (e^ax)dx = (1/a)(e^ax) + C, then in this case, we can let a = 3, and follow the formula to integrate this.
integral of (e^3x)dx = (1/3)(e^3x) + C, where C is an arbitrary constant.
This is choice D.

Determine the slope from the given graph below:
Greeley [361]

Step-by-step explanation:

the slope is the ratio of "y coordinate difference / x coordinate difference".

so, let's find 2 good points (I mean by that with integer coordinates). I see e.g.

(-1, -1) and (0, -7)

x changes by +1 (from -1 to 0).

y changes by -6 (from -1 to -7).

so, the slope is -6/1 = -6.

D is the right answer.

Find the x-coordinate of the point on the graph of y=x^2 where the tangent line is parallel to the secant line that cuts the cur
jek_recluse [69]
First find the secant line. The slope of the secant line through (-1,1) (when x=-1) and (2,4) (when x=2) is the average rate of change of y=x^2 over the interval [-1,2]:

\text{slope}_{\text{secant}}=\dfrac{2^2-(-1)^2}{2-(-1)}=\dfrac33=1

The tangent line to y=x^2 will have a slope determined by the derivative:

y=x^2\implies y'=2x

Both the secant and tangent will have the same slope when 2x=1, or when x=\dfrac12.

joja [24]
Given
   26% = several simulations of a football player playing two games 
Find the percentage of the simulations in each of the two games

2x = .26

2x = .26
----    -----
 2       2

x = .13 * 100
x= 13 

The answer is 13% of simulations would the football player be most likely to get a touchdown in each of the two games.
