Answer:
You would do rise over run (rise/run).
Step-by-step explanation:
Rate of change is basically slope, so you would do the same thing you would do to find the slope.
This is the concept of trigonometry, to solve for the value of the other length will be given cosine rule;
c^2=a^2+b^2-2ab cos C
substituting the values in our formula we get:
c^2=12^2+18^2-2*12*18*cos 60
c^2=144+324-432 cos60
c^2=252
hence
c=sqrt252
c=15.88m
thus the fixed length will be 15.88 m

Answer:
see picture and explanation
Step-by-step explanation:
on the graph if theres closed dots you use brackets [ ] for domain and range
closed dots mean the line stops on those exact numbers
if there's open dots or arrows you use parenthesis ( ) for domain and range
open dots or arrows means that the line continues forever (infinity)
Domain is the x values
on the first one the dots on each end are at -4 and 4 on the x axis
on the second one, since its arrows it continues forever so its negative infinity to infinity
(always remember for domain and range to put the smaller number first)
Range is the y values
the first one the dots stop at -1 and 5 at the ends on the x axis
on the 2nd question there are arrows so it never stops so its negative infinity to infinity again
End value is just what the graph is doing. so for both questions the graph starts at the lowest left corner which means its negative infinity going to negative infinity on that side from the origin (middle of graph) and then it rises from infinity to infinity on the other side of the origin. started positive and continuing to go positive.
I might have explained the end behavior incorrectly since its been awhile since I've done this. look up "end behavior" and look at images to get a better understanding
Answer:
<h2>x = 4</h2>
Step-by-step explanation:
Multiply through by 4 to eliminate the fraction
That's
<u>Subtract x from each side</u>
That's
<u>Subtract 8 from each side</u>
<u>Divide both sides by 3</u>
We have the final answer as
<h3>x = 4</h3>
