The Correct answer is 3
Explanation:
Using the defined function, f(a) will produce the same result when substituted for x:
F(x)=x^2-x^3
Setting this equal to 4, you can solve for a:
a2 – 5 = 4
a2 = 9
a = –3 or 3
1.35/9=0.15 which is the amount for one minute so multiple it by 16 to get 16 minutes
0.15x16=2.4 dollars
Answer:
x = 10

Answer:
Step-by-step explanation:
Given that total students =23.
15 have taken English, 13 Math and 8 both
number of students taking math only = total math - students who have taken both
= 13-8 = 5
Number of students taking English only = total English - students who have taken both
= 15-8 =7
Now we divided into 3 disjoint partitions as only Math, only English and both.
Thus no of students who have taken either math or english = 7+5+3 = 15
No of students who have taken neither = 24-15 = 9
