Answer:
Neither
Step-by-step explanation:
When you rearrange the equation 3x+2y=1 in the form of y=mx+c
you get:
2y=-3x+1
And if you compare it with the equation y= -x -1
You can see that the gradient is not the same, so it means it is not parallel.
To get if it is perpendicular you need to see if the two gradients multiply to give the value -1 but when you multiply
×
so it is not perpendicular as well
I hope it is right, feel free to point out anything wrong or you're unsure of :)
Answer:
14.1m above the sea level.
Step-by-step explanation:
h(t)=−4.9t²+4t+15, t in seconds
When t=0s, h(0)=15m (height of cliff), so it means that h is measured from the sea level.
After 1 second: h(1)=-4.9+4+15=14.1m above the sea level.
Given that the value of an industrial machine has a decay factor of 0.75 per year, and after six years, it became $7,500 only, this would mean that the original value of the machine would be solved like this: <span>7500 = x(1-.75)^6
</span>7500 = x(0.25)^6
7500 = x(<span>0.00024414062)
7500 = </span><span>0.00024414062x
x = </span><span>30, 720, 000
Hope this answers your question.</span>
