Answer:
The area of the parallelogram is 55 square unit.
Step-by-step explanation:
The area of a parallelogram is

It is given that the vertices of the parallelogram are  P(-2, -5), Q(9, -5), R(1, 5), S(12, 5).
Plot these points on a coordinate plane, and draw a perpendicular on PQ from the point R.
From the graph is clear that length of PQ is 11 and the height of the parallelogram is 10. So, the area of a parallelogram is


Therefore the area of the parallelogram is 55 square unit.
 
        
             
        
        
        
<span>The function h(t) = 210 – 15t has the slope-intercept form of the equation of a straight line.  The y-intercept represents the amount h at the very beginning (when t=0).  The negative slope (-15) represents the amount by  which h will decrease if t is increased by 1.
We are manipulating the value of time, t, so time, t, is the independent variable, and h(t) = y is the dependent variable.</span>
        
                    
             
        
        
        
Answer:
16°
Step-by-step explanation:
2x° + 6° = 38°
x° = (38°- 6°)÷2=16°
 
        
             
        
        
        
HOY = Horizontal line, m=0, y is the only variable in the equation
VUX = Vertical line, m= undefined, x is the only variable in the equation
