The correct answer is 5. This is because rate of change of a function or a line is its gradient. As we can see that the line is horizontal then the gradient must be equal to zero too.
On the other hand the equation is written in the form of y = mx + c where m is the gradient or slope and c is the y intercept so the gradient is equal to 5 if we match the places. So it is 5 times greater.
I think it’s b.5. Hope this helps. :)
The perimeter of a circle is its total circumference, but in this case a semi-circle will measure half the circumference plus its diameter.
If the semicircle measures 8cm then the total circle is 16 cm, and we can calculate its diameter or radius from there. The perimeter is defined as:
p = pi*diameter = 16
diameter = 16/pi = 16/3.14
diameter = 5.1 cm
Therefore the semi-circle perimeter is:
perimeter = semi-circle + diameter = 8 + 5.1 = 13.1 cm
You would start with the equation:Let m=number of miles
49.98+0.12m=35.98+0.17m
Then solve for m
You would then get
49.98+0.12m=35.98+0.17m
-0.12m -0.12m
49.98=35.98+0.05m
-35.98 -35.98
14 = 0.05m
---- --------
0.05 0.05
280=m
