Answer:
y^2 - 10y + 25
Step-by-step explanation:
(y - 5)^2 =
(y - 5) • (y - 5)
Multiply y times y
y^2
Add 5 and 5
10
Multiply 5 and 5
25
Add these terms together
y^2 - 10y + 25
No the triangle is not a right triangle
Let H = number of hours worked.
He gets $15 for every hour worked, so you need to multiply 15 by h which is written as 15h
You then need to add that to the $200 he gets for showing up.
Total pay = 15h + 200
Answer:
60g
Step-by-step explanation:
A sample of radioactive element has a mass that weighs 80g
The amount of life spent is two half-lives
This means that after two half lives, the number of daughter materials that would be available in the sample is 60g
Hence 60g of daughter cells would be available after two half lives
