Answer:

56.1 cm²

Step-by-step explanation:

In any circle the area (A) of a sector is

A = area of circle × fraction of circle

   = πr² × \frac{81}{360}

   = π × 8.91² × \frac{81}{360}

   = \frac{8.91^2(81)\pi }{360} ≈ 56.1 cm²

Find the coefficient of the x^3 in the expansion of (2x-9)^5
il63 [147K]

Use the binomial theorem:

\displaystyle (2x-9)^5 = \sum_{k=0}^5 \binom5k (2x)^{5-k}(-9)^k = \sum_{k=0}^5 \frac{5!}{k!(5-k)!} 2^5 \left(-\frac92\right)^k x^{5-k}

The <em>x</em> ³ terms occurs for 5 - <em>k</em> = 3, or <em>k</em> = 2, and its coefficient would be

\dfrac{5!}{2!(5-2)!} 2^5 \left(-\dfrac92\right)^2 = \boxed{6480}

What’s the translation from the graph y=6x^2 to the graph y=6(x+1)^2
Leno4ka [110]

For this case, the main function is given by:

y = 6x ^ 2

We can apply the following transformation:

Horizontal displacements:

Assume h> 0:

To graph f (x + h) move the graph of f (x) h units to the left.

For h = 1 we have:

y = 6 (x + 1) ^ 2

Answer:

the graph y=6(x+1)^2 is the graph y=6x^2 moved 1 unit to the left.
