Answer:
Step-by-step explanation:
is given value in dollars of a stock in t months after it is purchased.
a) Substitute 1 for t

V(12) = 
b) Find derivative for V

c) When V(t) = 75

d) As t tends to infinity, exponent being in negative t tends to 0
So V tends to 42(1-0)+36 = 78
Answer:
Step-by-step explanation:
x>10
x(then the weird E looking sign, then) (10,infinity)
First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
