Hello,
3y=6x+3 has as slope 2.
The perpendicular has the slope m*2=-1==>m=-1/2
The searched line has for equation y-4=-1/2(x-2) or y=-x/2+5
The answers are on Google if type in the topic and page number
Answer:
9:12
Step-by-step explanation:
since the others are multiples of 2:3
but 9:12 is not a multiple
The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.
<h3>What is the approximation about?</h3>
From the question:
Mars: F(x) = 2/3![\sqrt{64x}](https://tex.z-dn.net/?f=%5Csqrt%7B64x%7D)
Therefore, If x = 15
Then:
f (15) = 2/3 ![\sqrt[8]{15}](https://tex.z-dn.net/?f=%5Csqrt%5B8%5D%7B15%7D)
= 16/3![\sqrt{15}](https://tex.z-dn.net/?f=%5Csqrt%7B15%7D)
= 20.7ft/s
Hence, The nearest tenth of how fast a rover will hit Mars' surface after a bounce of 15 ft in height is 20.7ft/s.
