Answer:

Step-by-step explanation:
1) the common form of the point-slope form is y-y₁=s(x-x₁), where s - the slope, (x₁;y₁) - the point belongs to the required line;
2) if s=2.5; x₁= -5; y₁= -6, then the required equation is:
y+6=2/5(x+5).
Answer:
44, 6, and 24 are not perfect square
Step-by-step explanation:
Perfect square are numbers that can be square rooted with a result of a perfect whole number.
√16=4
√44= 6.63324...
√81= 9
√6= 2.44948...
√49= 7
√24= 4.898997...
The answer is a repeating decimal of 13.888... round accordingly.
Set up the proportion 5/18 = x/50 18x=250 Solve for x
Sry idk wish I could know but good luck
Answer:
0.50 kg of the material would be left after 10 days.
0.25 kg of the material would be left after 20 days.
Step-by-step explanation:
We have been given that the half-life of a material is 10 days. You have one 1 kg of the material today. We are asked to find the amount of material left after 10 days and 20 days, respectively.
We will use half life formula.
, where,
A = Amount left after t units of time,
a = Initial amount,
t = Time,
h = Half-life.




Therefore, amount of the material left after 10 days would be 0.5 kg.





Therefore, amount of the material left after 20 days would be 0.25 kg.
