Hi! hope this helped
B(d) is a function of the number of days d since she opened the account.B(0) is the balance at day=0 now, since the length of segment OA is half of the length of segment OB, and the length of segment OB is proportional to the max balance, namely $400, then the segment OA is proportional to 400/2=200
Answer:
125$ worth because you would not spend it all if you picked 625 and the others would give way too many away
Arc PR is 156 degrees. Since both angles are are making the forming arc they should be congruent. You can put (5x+23)=(9x-21) which is x=11.
Then you plug in 11 into your equation; 5(11)+23=78.
Since the vertex is on the outside of the circle then the arc is forms is 2 times the value of the angle.
78(2)=156

Answer:
D. 10.91 square centimeters
Step-by-step explanation:
Area of a sector of a circle = 
where 
radius (r) = half of diameter = 10/2 = 5 cm
Area = 
= 10.91
