Answer:
For the function  the average rate change from x is equal 1 to x is equal 2 is 4 .
 the average rate change from x is equal 1 to x is equal 2 is 4 .
Step-by-step explanation:
A function is given f(x)=4x-3.
It is required to find the average rate change of the function from x is 1 to x is 2 . simplify.
Step 1 of 2
A function f(x)=4 x-3 is given.
Determine the function  by putting the value of x=1 in the given function.
 by putting the value of x=1 in the given function.

Determine the function  by putting the value of x is 2 in the given function.
 by putting the value of x is 2 in the given function.

Step 2 of 2
According to the formula of average rate change of the equation 
Substitute the value of  with,
 with,  with
 with  with 2 and
 with 2 and  with 1 .
 with 1 .

 
        
             
        
        
        
Answer:
C. (1/2)acsinA
Step-by-step explanation:
Given is that, A, B, and C are the measures of the angles of a triangle and a, b, and c are the lengths of the sides opposite the corresponding angles.
So, the expression that does not represent the area of the triangle is :
C. (1/2)acsinA
 
        
             
        
        
        
Answer:
x = 30 in
Step-by-step explanation:
length of rectangle is (2/3)x + 10; width is (1/3)x + 5;
perimeter is 90 in; find x:
P = 90 in = 2(2/3)x + 2(10) + 2(1/3)x + 2(5), or
       90 in = (6/3)x + 30 in
Solving for x, we get (2)x = 60 in, or x = 30 in 
 
        
             
        
        
        
Mean is just another word for average. To find the average of something you must add up all values and divide by the number of values in the set.
        
             
        
        
        
Answer:
3. 3 : 5; 3: 5
Step-by-step explanation:
First, let's find the leght of the sides of each octagon.

The area of an octagon is defined by

Replacing the area

Therefore, the side of the first octagon is 1.6 inches long.
Its perimeter is: 


Therefore, the side of the second octagon is 3.8 inches long.
Its perimeter is  .
.
Now, let's divide to find each ratio:
 (the ratio between sides).
 (the ratio between sides).
 (the ratio between perimeters).
 (the ratio between perimeters).
Therefore, the closest ratio is 3. 3 : 5; 3: 5
