What method would you choose to solve the

Mathematics
1 answer:
olga nikolaevna [1]3 years ago
7 0

Answer:

This is a quadratic equation . We order to equate to zero

2x² – 7 = 9  

2x² - 7-9 = 0

2x² - 16 = 0

This equation is a binomial

2* (x² - 8) = 0

We choose the simplest method . The equation with practice it can be calculated in the memory

The product is equal to 0 if one of the factors is zero

2≠0  ∨     x² - 8 = 0

              x² = √8

              x = √8     ∨  x= - √8

Answer : x = √8 ∨ x = -√8

The true statements is the population was 4800 when the collection of data began. (3rd option)

<h3>What is an exponential function?</h3>

An exponential equation can be described as an equation with exponents. The exponent is usually a variable.

The general form of exponential equation is f(x) = e^{x}

Where:

  • x = the variable
  • e = constant

When a population grows at an exponential rate, it usually has compound rate of growth. Compound growth refers to the geometric progression of a variable.

The exponential equation used to represent an exponential growth usually have this form:

FV = PV (1 + r)^n

Where:

  • FV = future population
  • PV = present population
  • r = rate of growth
  • n = number of years

Given this exponential equation : f(x) = 4800 (1.02)^t

  • 4800 = initial population or population when the data collection began
  • 2 % = rate of growth
  • t = number of years
