-0.258 is a decimal number in which 2 is at the tenth place, 5 is at the hundredth place and 8 is at the thousandth place.

Therefore, the number in the fraction form is --\frac{258}{1000}

The fraction in the simplest form is --\frac{129}{500}

-0.312 is a decimal number and its fraction form is - -\frac{312}{1000}

The fraction in the simplest form is -\frac{78}{250} =-\frac{39}{125}

-2.32 is a decimal number and its fraction in the simplest form is

-2\frac{32}{100} =-2\frac{8}{25}

-1.64 is a decimal number and its mixed number in the simplest form is -1\frac{64}{100} =-1\frac{16}{25}

6.012 is a decimal number and the number in mixed number form is 6\frac{12}{1000}=6\frac{3}{250}

-12.405 is a decimal number and the number in mixed number form is

-12\frac{405}{1000}=-12\frac{81}{200}

Learning Task 1: Write and answer the following in your answer sheet
Marina CMI [18]

Answer:

Evaluating Polynomials:

a. f(1) = -10  

b. f(-3) = -239  

c. f(2)² = 3125

Factoring Polynomials:

a. (x + 1)(x² - 5x + 6) = (x + 1)(x - 3)(x - 2)  

b. (x² - x - 6)(x² + 6x + 9) = (x - 3)(x + 2)(x + 3)(x + 3)  

c. x³ + 3x² - 4x - 12 = (x + 3)(x - 2)(x + 2)(x - 2)(x + 2)

the birth rate in a certain country in 1994 was 14,6 birthd per thousand population. in 2004 the birth rate was 14.32 per thousa
amm1812

Answer:

y(x)=-0.028x+14.6

Step-by-step explanation:

Birth Rate in 1994 =  14.6 births per thousand population.

Birth Rate in 2004 =  14.32 births per thousand population.

A linear equation is of the form: y=mx+c

Where:

  • x=years after 1994
  • y=the birth rate
  • m=Yearly Birth Rate

First, we determine the birth rate per year

m=\dfrac{14.32-14.6}{10-0}\\=\dfrac{-0.28}{10}\\m=-0.028

Therefore, a linear equation that relates y in terms of x is of the form:

y(x)=-0.028x+c

When x=0, y=14.6

14.6=-0.028(0)+c

c=14.6

Therefore, the linear equation that relates y in terms of x is:

y(x)=-0.028x+14.6
