Find the average value of f(x)=e2x over the interval [2, 4].
shusha [124]
<h2>Option B is the correct answer.</h2>

Step-by-step explanation:

We need to find average value of e^{2x} in [2,4]

Area of e^{2x} in [2,4] is given by

                  \int_{2}^{4}e^{2x}dx=\frac{1}{2}\times \left [ e^{2x}\right ]^4_2\\\\\int_{2}^{4}e^{2x}dx=\frac{1}{2}\times(e^8-e^4)=1463.18

Area of e^{2x} in [2,4] = 1463.18

Difference = 4 - 2 = 2

Average value = Area of e^{2x} in [2,4] ÷ Difference

Average value = 1463.18 ÷ 2

Average value = 731.59

Option B is the correct answer.

How do you find the value for x? <br> Find the value of x ?
bogdanovich [222]

Answer:

x = 27

Step-by-step explanation:

Both angles together form 180 degree.

Set your formula up as

180 = (5x+2) + (x + 16)

180 = 5x + 2 + x + 16

180 = 6x  + 18

180 - 18 = 6x

162 = 6x

162/6 = x

27 = x
