Answer:
$98.15
Step-by-step explanation:
2005 is 15 years after 1990. Using the formula we find ...
c(15) = 63·1.03^15 ≈ 63·1.55797
c(15) ≈ 98.152
An ounce of the chemical costs about $98.15 in 2005.
It could be 10000,9800,or 9710
X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
28 to 16
Divide both numbers by 4.
7 to 4
