Answer:
I’m pretty sure it’s 160
Step-by-step explanation:
40 mph times 4 hours is 160 miles
Assuming you'd like to have it factored:
Given:
<span>18x^4 + 12x^2y + 2y^2
First take out common factors to all three terms, 2
=2(9x^4+6x^2y+y^2)
Rewrite with x^2 as a group (attempting to factor as perfect square)
=2((3x^2)^2 + 2(3x^2)(y) + y^2)
factor into perfect square
=2(3x^2+y)^2</span>
Answer: A
Step-by-step explanation:
a • (b•c) = (a•b) • c
Answer: It will take 6 years for 7500 grams of X to reach 6900 grams.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
b) for 7500 g to reach to 6900 g
It will take 6 years for 7500 grams of X to reach 6900 grams.
