Answer:

And we can solve for
and we got:



And we can solve for
and we got:


So then the coordinates for B are (3,8)
Step-by-step explanation:
For this case we know that the midpoint for the segment AB is (2,5)
And we know that the coordinates of A are (1,2)
We know that for a given segment the formulas in order to find the midpoint are given by:

And we can solve for
and we got:



And we can solve for
and we got:


So then the coordinates for B are (3,8)
Answer:
the answer is 500. hope this helps give me brainlest please.
Answer: y=23
Step-by-step explanation: You find the slope by doing rise over run. You go up 6 units and right two units to get from your first point to your second point. (This means your slope is 6/2 which is 3 btw). So with this problem specifically, you can see that the y values increase by 6 each time so all you do is add 6 again since it is a linear (straight line) function
Answer:

Step-by-step explanation:
The intensity β of a sound wave in decibels is given by the formula

and I₀ = the reference intensity (10⁻¹² W/m²)
Data:
I = 10⁻⁴ W·in⁻²
Calculations:
1. Convert watts per square inch to watts per square metre

2. Convert the intensity to decibels.

I’m pretty sure the answer is a
