Step-by-step explanation:
By Geometric mean property:

Answer:
28/21
Step-by-step explanation:
You would do y1 - y2 for the numerator which gets you 28. Then you would do x1 - x2 for the denominator which gets you 21. The rate of change is also the slope.
Hope this helps!
Answer: If p is true and q is true, then p → ~ q is always true.
Explanation: The result of the logical statement is true, therefore the finalized statement is equivalent.
Answer:
27.44 square cm
Step-by-step explanation:
If the length of parallelogram is a and b and angle between side a and b is
.
Then area of parallelogram = 
Given side length 4 cm and 7 cm
angle between them = 100°
value of sin(100°) = 0.98
Thus, area of given parallelogram = 4*7*sin(100°) = 28*0.98 = 27.44
Thus, area of given parallelogram is 27.44 square cm.
