Answer:

<h2>The area of the sector is 40πcm²</h2>

Step-by-step explanation:

The question looks incomplete. Here is the restructured question.

"A sector with a radius of 8cm has a central angle measure of 225°. Find the area of the sector"

Formula for calculating the area of the sector is given as shown;

Area of a sector= \frac{\theta}{360^{0} } *\pi r^{2}

\theta is the central angle and r is the radius of the circle.

Given radius = 8 cm and \theta = 225°

On substitution, area of a sector = \frac{225}{360} * \pi (8)^{2} \\

= 225/360 * 64\pi \\=0.625*64\pi \\= 40\pi cm^{2} \\

The area of the sector is 40πcm²

3. The pay rate for employee C is less than the pay rate for employee B
mel-nik [20]

Answer:

y = xc

Step-by-step explanation:

Let the pay rate for employee C per hour is $c and the pay rate for employee B per hour is $b and the pay rate for employee A per hour is $a.

Now, it is given that b > c > a.

Now, the equation for the possible pay y in dollars per day that C earns working x hours per day will be y = xc.

Therefore, the equation for possible pay to employee C is y = xc. (Answer)

How do I do this and whats the answer please
stepladder [879]

Answer:

slope= - 3/4

A(-4,3) and B(4,-3)

slope=m=\frac{y_B-y_A}{x_B-x_A} =\frac{-3-3}{4-(-4)} =\frac{-6}{8} =-\frac{3}{4}

The average rate of change from x = 0 to x = 15 is about −4.667. How does the average rate of change from x = 0 to x = 20 compar
Amanda [17]
First we calculate the ambio rate from x = 0 to x = 15:
 We have:
 R = ((80-10) / (0-15))
 R = -4.666666667
 We now calculate for the entire interval:
 from x = 0 to x = 20:
 R = ((80-2) / (0-20))
 R = -3.9
 Answer:
 What is the average rate of change over the entire slide?
 R = -3.9
 The average rate of change from x = 0 to x = 15 is about -4.667. How does the average rate change from x = 0 to x = 20 compare to this number?
 The percentage difference is:
 (-3.9 / -4.666666667) * (100) = 83.57142857%
 100-83.57142857 = 16.42857143%
