Find the average value of the function on the given interval.<br> f(x)=(2x-1)1/2; [1,13]

Leni [432]

Answer:

The average value of the function on the given interval 6.5.

Step-by-step explanation:

Consider the given function is

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

We need to find the average value of the function on the given interval [1,13].

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

$f(x)=x-0.5$

The average value of the function f(x) on [a,b] is

$Average=\dfrac{1}{b-a}\int\limits^b_a {f(x)} \, dx$

Average value of the function on the given interval [1,13] is

$Average=\dfrac{1}{13-1}\int\limits^{13}_{1} {x-0.5} \, dx$

$Average=\dfrac{1}{12}[\dfrac{x^2}{2}-0.5x]^{13}_{1}$

$Average=\dfrac{1}{12}[\dfrac{(13)^2}{2}-0.5(13)-(\dfrac{(1)^2}{2}-0.5(1))]$

$Average=\dfrac{1}{12}[78-0]$

$Average=6.5$

Therefore, the average value of the function on the given interval 6.5.

2 is on the line 4x - 5y = -7 find the other half of the coordinate

natali 33 [55]

4x - 5y = -7

When x = 2,
4(2) - 5y = -7
8 - 5y = -7
5y = 15
y = 5

Answer: The other half of the coordinate is 5.

A baseball team played 160 regular season games. the ratio of the number of games they won to the number of games they lost was

timurjin [86]

They won 96 games because 160 divided by 5 is 32. now 32 times 3 equals to 96. :) Hope this helps

Solve for x 38=3x+35

olganol [36]

Answer:

x = 1

Step-by-step explanation:

Keep the variable left alone by removing any numbers next to it-

3x = 33

Divide each side by 3 to keep x by itself

3x/3 = x

3/3 = 1

x = 1

Simplify-

x = 1
