Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval?

liq [111]

Answer:

7/3

Step-by-step explanation:

f(x) = 3x^2 + 2x + 1, [0, 2]

f(0)=1

f(2)=17

f'(c)=f(2)-f(0)/2-1

f'(c)=17-1/1=16

f'(c)= 6x+2

6x+2=16

6x=16-2

6x=14

x=14/6

x=7/3

In this triangle, what is the value of x?

nalin [4]

Answer: $x=56.5\ km$

Step-by-step explanation:

Given the right triangle in the image, you need to remember the following identity:

$cos\alpha=\frac{adjacent}{hypotenuse}$

Observe the triangle. You can identify that:

$\alpha=28\°\\adjacent=x\\hypotenuse=64$

Then, knowing these values, you can substitute them into $cos\alpha=\frac{adjacent}{hypotenuse}$ :

$cos(28\°)=\frac{x}{64}$

Finally, you have to solve for "x".

Therefore, the value of "x" rounded to the nearest tenth is:

$64*cos(28\°)=x\\x=56.5\ km$
