The slope is defined as the first derivative of the equation so ,
d(r)/d(theta) = -2 sin(2theta)
and by substitue by theta = pi/2
we get slope = -2 sin(2*(pi/6))
slope = -√3
145% of what number is 870 is 870/1.45=600
Answer=600
Piecewise functions are a group of sub-functions that have their own set of domain and range interval. Together, these sub-functions make up the total domain or range. Therefore, you need to explicitly define the interval because this sets the boundaries of each sub-function of the piecewise functions.
m = amount of money you receive
You need at least $40, so that means you need m = 40 or more
So which is the same as saying . You flip both sides and also flip the inequality sign as well.
At the same time, your parents won't give you more than $50. So the largest m can get is m = 50. This means
-----------------
Combine and to get the compound inequality
This represents all the possible values of m. We see that m can get as small as m = 40, or as large as m = 50, or anything in between.

Answer:
The answer looks to be 35! See where the line stops in bettween 30 and 40?^^
Hope this helps! Let me know if its correct or not!
