Answer:
86.5 square inches
Step-by-step explanation:
Area of circle: pi*r^2
10.5in /2= 5.25in
5.25^2=27.5625
27.5625*3.14=86.54625
rounded 86.5 in
 
        
             
        
        
        
Converse (switch p and q)
If an angle is obtuse, then it measures 128°
This is false (a 127° angle is obtuse, but it does not measure 128°)
_____________________________________________________________
Inverse (negations of p and q)
If an angle does not measure 128°, then it is not obtuse
This is false (a 127° angle does not measure 128°, but it is obtuse)
_____________________________________________________________
Contrapositive (negations of p and q, then switch their places)
If an angle is not obtuse, it does not measure 128°
This is true (any 128° is obtuse; no exceptions)
        
             
        
        
        
128 = a + + 4(a + 10) + (a + 10) 
128 = a + 4a + 40 + a + 10
128 = 6a + 50
128-50 = 6a
78 = 6a
13 = a
1st = a = 13
2nd = 4(a + 10) = 4(23) = 92
3rd = a + 10 = 23
        
             
        
        
        
Answer:
 
   
Step-by-step explanation:
The table shows a set of x and y values, thus showing a set of points we can use to find the equation. 
1) First, find the slope by using two points and substituting their x and y values into the slope formula,  . I chose (-3, 13) and (0,17), but any two points from the table will work. Use them for the formula like so:
. I chose (-3, 13) and (0,17), but any two points from the table will work. Use them for the formula like so: 

Thus, the slope is  .
. 
2) Next, identify the y-intercept. The y-intercept is where the line hits the y-axis. All points on the y-axis have a x value of 0. Thus, (0,17) must be the y-intercept of the line. 
3) Finally, write an equation in slope-intercept form, or  format. Substitute the
 format. Substitute the  and
 and  for real values.
 for real values. 
The  represents the slope of the equation, so substitute it for
 represents the slope of the equation, so substitute it for  . The
. The  represents the y-value of the y-intercept, so substitute it for 17. This will give the following answer and equation:

Step-by-step explanation:
You can put the value of x into the equation to solve for y. Hopes this works.
