Answer:

  451.2 million

Step-by-step explanation:

We can write the exponential growth equation as ...

  N(t) = 231·e^(0.0103(t-1980))

Then N(2045) = 231·e^(0.0103(2045-1980)) = 231·e^0.6695 ≈ 451.2

The population is predicted to be 451.2 million in 2045 if the growth continues at the same rate.

4.2 Find roots (zeroes) of : F(x) = x3 - 15x2 + 50
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient

In this case, the Leading Coefficient is 1 and the Trailing Constant is 50.

The factor(s) are:

Write y = –2/5x – 3 in standard form using integers.
guajiro [1.7K]
The standard form is:
a x + b y = c
y = - 2/5 x - 3  / *5 ( we will multiply both sides of an equation by 5 )
5 y = - 2 x - 15
Answer:
2 y + 5 y = - 15
