Step-by-step explanation:
2x² + 8y = 121.5
x² - 8y = 121.5
Add the equations together to eliminate the y terms.
3x² = 243
x² = 81
x = 9
Hello!
You find the volume of a rectangular prism if the length is x, the width is x2, and the height is 5x2 + 4x + 1. Use the formula
<span>V = l ⋅ w ⋅ h, where l is length, w is width, and h is height, to find the volume.
</span>
Solution:
So in this Case, we can see that the Length = x, Width = x², and Height = 5x2 + 4x + 1. Remember: (V = l . w . h)<span>
Use the formula:</span>
<span>V = l ⋅ w ⋅ h,=x×x²×(5x²+4x+1)
</span>
<span>=x³×(5x²+4x+1)
</span>
=5x^5+4x^4+x³

Answer:
It descends 3 km.
Step-by-step explanation:
The rate of change is the slope. The formula for slope is
Using the first two points, (0, 12) and (2, 10), we have
m = (10-12)/(2-0) = -2/2 = -1
This means the plane descends 1 km per minute. This means in 3 minutes' time, the plane descends 3 km.
