Answer:

18π cm² ≈ 56.5 cm²

Step-by-step explanation:

The area of the sector can be found using an appropriate area formula.

<h3>Sector area</h3>

When the sector central angle is given in radians, the formula for the area of that sector is ...

A = 1/2r²θ . . . . . . where θ is the central angle, and r is the radius

When the angle is in degrees, the formula will include a factor to convert it to radians:

A = 1/2r²θ(π/180) . . . . where angle θ is in degrees

A = (πθ/360)r² . . . . simplified slightly

The figure shows r=9 cm, and θ=80°. Using these values in the formula gives an area of ...

A = π(80/360)(9 cm)² = 18π cm² ≈ 56.5 cm²

2 feet 7 inches.

5 feet - 2 feet is 3 feet
3 inches - 8 inches is - 5 inches.

Determine whether the ffunction X/(x^2-1) is odd even or neither

djyliett [7]

equation is:

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

so if its even f(-x) should be equal to f(x)

that means

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

so f(x) is not equal to f(-x) so its not even

If its odd than f(-x) should be equal to -f(x)

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

so as we can see f(-x)= - f(x)

so the function is odd

Ans:function is odd and not even

Solve for w: k = 3pw<br> please help i have no clue

navik [9.2K]

Answer:

$w = \dfrac{k}{3p}$

Step-by-step explanation:

k = 3pw

Step 1: switch sides.

3pw = k

Step 2: Since you want w alone, and w is being multiplied by 3p, divide both sides by 3p.

$w = \dfrac{k}{3p}$

Answer:

<em>MQ = 16 units</em>

Step-by-step explanation:

$\frac{x}{14}$ = $\frac{9}{63}$

x = $\frac{14*9}{63}$ = 2

<em>MQ</em> = 14 + 2 = <em>16 units</em>

Find the length of the missing side Geometry

leonid [27]

Since it is a right triangle we can use Pythagorean Theorem to solve.

A^2+B^2=C^2

We are given C and B. We are solving for A, so we can input what we know.

A^2+24^2=25^2

A^2+576=625

A^2=49

A=7

Therefore, the missing side is equal to 7.
