Answer:
9
Step-by-step explanation:
You choose the middle one because 3<(4)<10 makes sense where as the other ones don't when you plug in 4. Then you solve the equation which is x^2-7 and then you get 16-7 which is 9.
 
        
             
        
        
        
Answer:
<h2>20</h2>
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- a straight line contains 180°
<h3>let's solve:</h3>
according to the question
7x+x+20=180
=>8x+20=180
=>8x=160
therefore
x=20
 
        
             
        
        
        
Answer:
d. -38
Step-by-step explanation:
Arithmetic sequence concepts:
The general rule of an arithmetic sequence is as follows:

In which d is the common diference between each term.
We can expand the general equation to find the nth term from the first, by the following equation:

In this question:

17th term:

So the correct answer is:
d. -38
 
        
             
        
        
        
The slope-intercept form is simply the way of writing the equation of a line so that the slope (steepness) and y-intercept (where the line crosses the vertical y-axis) are immediately apparent. Often, this form is called y = mx + b form.
 
        
                    
             
        
        
        
The quadcopter's average velocity is given in terms of change in position by

where  , the difference in the quadcopter's final and initial positions and
, the difference in the quadcopter's final and initial positions and  .
.
The  -component of the average velocity is 2.70 m/s, so
-component of the average velocity is 2.70 m/s, so

and the  -component is -2.50 m/s, so
-component is -2.50 m/s, so
