* 4. A circle is divided into ten equal sectors.

Fiesta28 [93]

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

$= {360}^{0} \div 10$

$= {36}^{0}$

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

$= \frac{1}{n} \times 2\pi \times r$

$= \frac{1}{10} \times 2\ \frac{22}{7} \times 50$

$= 31.42 \: in$

Simplify each expression. Use positive exponents. <br> (x–2y–4x3) –2,

Contact [7]

The Expression is
(x^-2y^-4x³)^-2
We can combine the x terms inside the brackets using the concept;
x ^a × x^b = x^(a+b)
Therefore,
(x^-2)(x^3) = x^(3-2) = x^!

Thus we get;
(xy^-4)^-2
Using the concept
(x^a)^b = x^(ab)
Therefore
= x ^(-2×1) y^(-2×-4)
=x^-2y^8
But using the concept; x^-a = 1/x^a
Thus, x^-2y^8 = y^8/x²
Hence the simplified equation is;
= y^8/x²
