Answer: The value of x in quadrilateral ABCD is 9 cm.
Since both pairs of sides are parallel, this shape is also a parallelogram. The area of a parallelogram is base times height.
Therefore in this parallelogram, we can write and solve the following equation.
A = B x H
63 = 7x
9 = x
The height must be 9 cm.
Alright, so the scale of meters to feet is about 3.281 feet. So you would do 10.7 times 3.281 and that equals 35.1067 and that can be rounded to 35, so the answer would be C, 35 feet. Hope that Helped :)!
Answer:
The ball will take approximately 2.165 seconds.
Step-by-step explanation:
The height of the ball is represented by the function
, the time taken by the ball to hit the ground is a value of
such that
, we proceed to solve the following equation for
:
(1)
![16\cdot t^{2} = 75](https://tex.z-dn.net/?f=16%5Ccdot%20t%5E%7B2%7D%20%3D%2075)
![t = \sqrt{\frac{75}{16} }](https://tex.z-dn.net/?f=t%20%3D%20%5Csqrt%7B%5Cfrac%7B75%7D%7B16%7D%20%7D)
![t \approx 2.165\,s](https://tex.z-dn.net/?f=t%20%5Capprox%202.165%5C%2Cs)
The ball will take approximately 2.165 seconds.
