mrs bastille is landscaping her garden. she wants to add pebbles to the edge of the garden, between the garden and the fence. the dimensions of the garden are 4.3 ft by 2.5. the dimensions of the fence are 5.7 by 3.7. what is the area ? a) 21.90, b)10.34 c) 31.84

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

multiply each one by 3.14
