Answer:
60%
Step-by-step explanation:
<span><em>D(x) is a function.</em> TRUE. It is a function of x.
</span><span><em>x is the dependent variable.</em> FALSE. x is the independent variable because the function is expressed in terms of the independent variable.
</span><span><em>D(6) = 3</em>. FALSE. D(6) = 2(6) = 12. D(6) should be equal to 12.
</span><em>D(x) is a direct variation.</em><span> TRUE.</span><span> This holds true to the definition of direct variation where one variable is related to the other variable at the same constant multple. In this case, it is 2.
</span><span><em>D(x) is a rule for the set of points (5, 10), (6, 12) and (-2, -4).</em> TRUE. If you replace x with the first coordinate, the function would be equal to the corresponding second coordinate.</span>
Answer:
2.5 in
Step-by-step explanation:
Ok so since this is a parallelogram you want to follow the formula but in reverse
A=1/2H(b1+b2)
So do 33.6+16.8 (50.4)
Then divide that into your area (126)
126/50.4=2.5
Use x and y coordinate separately for distance.
Sqrt{ (6-2)^2 + (-1-3)^2 }
Sqrt(32)
4sqrt(2)
