Answer:

A = 27π cm²

Step-by-step explanation:

the area (A) of the sector is calculated as

A = area of circle × fraction of circle

the central angle of the shaded sector = 360° - 90° = 270° , then

A = πr² × $\frac{270}{360}$

= π × 6² × $\frac{3}{4}$

= 36π × $\frac{3}{4}$

= 9π × 3

= 27π cm²

The graph of the function f(x) = –(x + 6)(x + 2) is shown below.Which statement about the function is true?

LekaFEV [45]

Answer:

The first statement is true.

Step-by-step explanation:

The function is f(x) = - (x + 6)(x + 2)

⇒ f(x) = - x² - 8x - 12

Now, condition for a function f(x) to be increasing at x = a is f'(a) > 0.

Now, f(x) = - x² - 8x - 12

⇒ f'(x) = -2x - 8 {Differentiating with respect to x}

Now, f'(a) = -2a - 8 {Here a can be any real value}

And, the condition for increasing function at x = a is

- 2a - 8 > 0

⇒ - 2a > 8

⇒ a < - 4

Therefore, the first statement is true i.e. the function is increasing for all real values of x where x < – 4. (Answer)

3000 millimeters equals how many meters

Zielflug [23.3K]

In 1 meter there are 1,000 millimeter.

When you go from small (mm) to big (m) you always divide the small (mm) by what the equivalent of 1 big (m) but in terms of the small (mm)

^^^That's a bit confusing so I will work it out so it makes more sense...

$3,000 / 1,000$

^ this is the equivalent to 1 meter (the big in this case)

3 m = 3,000 mm

Hope this helped! Let me know if there is anything else that I can do!
