I believe you meant f(x) = x^2 - 3x - 10.
                                                              f(b) - f(a)
The ave. r. of c. formula is     a. r. c = -----------------
                                                                 b -a
                               (6)^2 - 3(6) - 10 - [(4)^2 - 3(4) - 10]
Here,   a. r. c. =   ------------------------------------------------------        
                                                      6-4
                                           36 - 18 -10 - 16 + 12 + 10
     ... which comes out to ---------------------------------------
                                                                2

                a. r. c. = 7             for x^2 - 3x - 10 on the interval [4,6]

A pair of jeans that originally costs $42 is 25% off.Find the sale price.ASAP PLZ!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Anon25 [30]
Original Price = $42
Discount = 25%   ---------> 25% is discount because it says 25% <span><u />off!!!</span>
Now,
Sale price = original price - discount % of original price  
                 = 42 - 25% of 42 
                 = 42 - (25/100) * 42   
                 = 42 - 0.25 * 42 
                 = 42 - 10.5 
                 = 31.5

So, the sale price is $31.5

Which graft represent -3x+5y=-15
azamat

The graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

-3x + 5y = -15

The above function shows a linear function we can write it as:

5y = 3x - 15

y = (3x - 15)/5

If x = 0, y = -3

x = 1, y = -2.4

x = 2, y = -1.8

x = -1, y = -3.6

x = -2, y = -4.2

Thus, the graph of the function -3x+5y=-15 is a linear function we can draw it by finding the values of y for every value of x.

Point P is the center of the circle below. What is the exact area
Ber [7]

Answer:

192π unit²

Step-by-step explanation:

Given that :

Radius = 24

Area of circle = πr²

Area = π*24²

Area = 576π in²

The Shaded area is 120°

Entire Circumference = 360°

Hence, shaded area = 120°/ 360° = 1/ 3 of the area

1/3 * 576π in²

= 192π unit²
