Let's find out the gradient (Slope " m ") of line q ;



Now, since we already know the gradient let's find of the equation of line by using its Slope and one of the points using point slope form of line :


Now, plug in the value of gradient ~

here we can clearly observe that, the Area under the curve can easily be represented as :

Since, all the values of y that lies in the shaded region is smaller than the actual value of y for the corresponding values of x in the equation of line q
Answer:
D
Step-by-step explanation:
The parabola opens up. Which means the vertex is the minimum value.
Answer:
76 degrees
180-38-38 is 104
180-104 is 76 since it's a straight line which equals to 180 degrees
Answer: 72
Step-by-step explanation: volume of a pyramid = v= lwh/3
v= 6*6*6/3
v = 216/3
v = 72
4 hours? i may be wrong
i did - 60 * 15
seems about right, since 50% would be 7.5 hours?
