We find<span> the first derivative of the curve, and evaluate it at </span>x<span>=1 (which we will use to obtain the </span>slope<span> of the </span>line tangent<span> to the curve at (1,−1)). So we have a </span>point<span> on the </span>tangent line: (x0,y0<span>)=(1,−1) and the </span>slope<span> of the </span>line tangent<span> at that </span>point<span>: m=−13.</span>
The radius is <span>24.5
R = C/2pi
</span>
So first let’s multiply both sides by 10
Now we are left with this:
-4x-90<9
Now you want to move the -90 to the other side and when you do this you have to change the sign as well so now you have this:
-4x<9+90
Now add 9 and 90 together and you’ll get this:
-4x<99
Then divide both sides by -4 and flip the inequality sign
x>- 99/4
Your answer would be:
x>- 99/4
Hope this helps! :3
The definition of mean, is to add up all the numbers and divide it by how many numbers there are. So, in this case the mean would be 1+1+1+2+2+2+2+3+3+4+4+4+4+5+5+6+7+7+8+8+9 = 86. You would then take 86 and divide that by 21, and you would get 4.0
The definition of median states to find the middle of the numbers. So the median would be 4.
So you would just take 4 - 4 = 0.
0 would be correct.
