The population of a type of plant in a forest is given by P - 2000$ where t is
the number of weeks since the seeds
were planted. Find the population of
the plants on the 8th week.

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
