Circumference = 2 x PI x r

= 2 x 3.14 x 30 = 60 PI
the area from x to y = 90 degrees
so XPY would be 360 - 90 = 270 degrees or 3/4 of a full circle

so XPY = 60 x 3/4 = 45 PI meters

Circumference of a circle = 2πr

Circumference of the whole circle= 2π(30) = 60π

360 - 90 = 270

Length XPY = 270/360 x 60π = 45π

Answer: 45π m

What is the value of the function at x = 3? Enter your answer in the box.

SOVA2 [1]

Answer:

Step-by-step explanation:

REMEMBER: Y is = f(x).

So the function is equal to the y value.

When x is 3, y is (if you go up the line intersects at) 4.

The value of he function when x = 3 is 4.

Sergio039 [100]

Answer:

m = -6

Step-by-step explanation:

3m = 2(m - 3)

Distribute

3m = 2m - 6

Subtract 2m from each side

3m -2m = 2m-2m -6

m = -6

Help!!! Divide the polynomial by 7x

HACTEHA [7]

Answer:

$4x^4-9x^3+x^2$

Step-by-step explanation:

Dividing the polynomial by 7x means dividing each term by 7x, as shown below:

$\frac{28x^5-63x^4+7x^3}{7x}\\=\frac{28x^5}{7x}-\frac{63x^4}{7x}+\frac{7x^3}{7x}\\=4x^4-9x^3+x^2$

In dividing, we also used the property of exponents, shown below:

$\frac{a^x}{a^y}=a^{x-y}$

So the answer is: $4x^4-9x^3+x^2$
