Answer:
A) .05
B) 3.20
Step-by-step explanation:
1.45-1.40 = .05
13.25-10.05 = 3.20
Answer:
7
Step-by-step explanation:
This problem deals with order of operations. If you solve the problem from left to right, you will get an incorrect answer. Instead recall PEMDAS.
Parentheses first
Exponents
Multiplication and Division (left-to-right)
Addition and Subtraction (left-to-right)
We start with the division, as there are no parentheses or exponents. 3÷3=1.
Now we can replace the 3÷3 with a 1 in the expression.
7-1.0+1
Since we only have addition and subtraction left, we now proceed from left to right.
7-1.0=6, and 6+1=7.
or
7-1.0+1=7.
Therefore, the answer is 7.
Solving this problem is just pretty straight forward. All
we simply have to do is to plug in the value of t (in days) in the function,
solve then we get the number of susceptible people.
A. At the beginning of the epidemic
t = 0
f(x) = 15000 e-^(0.05 * 0)
f(x) = 15000
B. After 14 days
t= 14
f(x) = 15000 e-^(0.05 * 14)
f(x) = 7,448.78 = 7,449
C. After 21 days
t = 21
f(x) = 15000 e-^(0.05 * 21)
f(x) = 5,249
D. After 5 weeks
t = 5 * 7 = 35
f(x) = 15000 e-^(0.05 * 35)
f(x) = 2,606.61 = 2607
