Answer:
After 46 years, the population of this country will be doubled.
Step-by-step explanation:
Given that,
The population of a certain country is growing rate 1.5%.
The formula for this is
t= time in years
k=population growth rate.
Here k=1.5% 
= 0.015
≈46 years
After 46 years, the population of this country will be doubled.
3x^2y^4z - 6xy - 3z(5x^2) has three terms.
Answer:
In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of ... The decimal expansion of a rational number either terminates after a finite
Step-by-step explanation:
Answer:
The resultant of the two vectors is (0,0).
Step-by-step explanation:
- The ordered pair is : (-6,5) and (6,-5).
- The resultant is the vector sum of two or more vectors. It is the result of adding two or more vectors together.
- The vector resultant is calculated as:
Abscissa of resultant= -6 + 6 = 0
Ordinate of the resultant= 5- 5= 0
- Hence the resultant has the co ordinate of (0,0).
y = abˣ
20 = ab¹
20 = ab
b b
20/b = a
y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b
y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b
y = abˣ
y = 100(0.2)ˣ
