Answer:
Step-by-step explanation:
In any rhombus, the four sides are the same length.
Because of this, we know that
Furthermore, AC = AC due to the reflective property
Those three facts then allow us to prove triangle ACD is congruent to triangle ACB through the SSS congruence property. Then from CPCTC, we then know that angle DAC = angle BAC, which is enough to show that AC bisects the angle shown. The term "bisect" means "cut in half".
Answer:
The value will be 56
Step-by-step explanation:
We have given polynomial 
We have to find P(-2)
For finding P(-2) we have to put x = -2 in the polynomial
So P(-2) = 
So value of P(-2) will be 56
For finding any value we have to just put that value in the polynomial
Answer:
Option A. 10 years
Step-by-step explanation:
we know that
Half-life 
is the amount of time required for a quantity to fall to half its value as measured at the beginning of the time period.
In this problem of a radioactive isotope is 10 years, which means that after 10 years half of the sample would have decayed and half would be left as it is.
After 10 years ( first half life) 5/2 = 2.5 g decays and 2.5 g remains left
