Answer:
93
Step-by-step explanation:
Given in the question an expression
5 + 10² – 3 × (12 – 8)
To solve this we will use DMAS rule is followed when multiple arithmetic operations are there in a given problem like addition, subtraction, multiplication and division. It tells they should be performed in order of Division, Multiplication, Addition and Subtraction
Step 1
10²
100
5 + 100 – 3 × (12 – 8)
Step 2
(12 – 8)
(4)
5 + 100 – 3 × (4)
Step 2
3 × (4)
12
5 + 100 – 12
Step 3
5 + 100
105
105 - 12
Step 4
105 - 12
93
First find the rate of growth (k)
P=Ae^kt
P 76 million
A 72 million
E constant
K ?
T time 1998-1992=6 years
Solve the formula for k
K=[log (P/A)÷log (e)]÷t
K=(log(76÷72)÷log(e))÷6
k=0.009
Now find the population in 2012
P=Ae^kt
P ?
A 72 million
E constant
K 0.009
T time 2,012−1,992=20 years
P=72×e^(0.009×20)
p=86 million. In 2012
X is 4
4(4) is 16 plus 13 equals 28
