Answer:
<h3>1 secs</h3>
Step-by-step explanation:
Given the height of the discus can be modeled by the equation y=−16x
^2
+32x+4, where y represents the height in feet of the discus in seconds, the velocity of the discus at its maximum height is zero.
Velocity v = dy/dx = 0
dy/dx = -32x + 32
0 = -32x + 32
32x = 32
x = 1 secs
Hence it will take the discus 1 secs to reach its maximum height
The answer is: 117m²
The explanation is shown below:
1. You have the following information given in the problem:
- The triangle has an area of 13 m².
- The dimensions of the triangle are increased by a scale factor of 3.
2. Therefore, to solve the exercise you must multiply the area by 
, as following:
Standard form is Ax + By = C, or By = C - Ax.
Dividing both sides by B, we get y = C/B - (A/B)x
Here the y intercept is C/B, and the slope is -A/B.
