Answer:
$3.51
Step-by-step explanation:
1 pound is $2.39 so divide by 2 and round up to the nearest whole number which is $1.12. Add $1.12(The cost of 0.5 pounds) to $2.39(The cost of 1 pound) to get $3.51 as your total.
Answer:
See explanation
Step-by-step explanation:
Assuming you want to find the 3rd term of the geometric progression defined explicitly by 
, then we have to substitute n=3 to obtain:
This will give us:
We evaluate to obtain:
Answer:
43.2 × 10^-6
Step-by-step explanation:
(6 x 10^-8)(7.2 x 10^4)
43.2 × 10^-6
Answer:
T > -9/28
Step-by-step explanation:
A quadratic has two real solutions when the discriminant (b² - 4ac) is positive.
b² - 4ac > 0
3² - 4(T)(-7) > 0
9 + 28T > 0
28T > -9
T > -9/28
