At the beginning of an environmental study a forest cover an area of 1500 km second power since then this area has decreased by 4.8% each year let t be the number of years since the start of the study letter y b the area that the forest covers in km to the second power write an exponential function showing the relationship between y& t

Step-by-step explanation:

Explicit formula of an exponential function is given by

= Area covered by the forest after time t

= Initial area covered by the forest

b = (1 - r)

and r =  rate of decay of the forest area

t = time in years

Therefore, function representing relationship between y and t will be

answer: a) 56% women

b)44% men

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
