<span>f(x<0)=-f(x>0)=-x^2+5x+12
When x>0, x^2-5x-12=12, x=8, y=12
Therefore, f(x)=12 goes through point (8,12).</span>
So, 0.5^5 is 0.03125
multiply that by 125 and get your answer.
*3.90625* (4)
just saying, I got the 0.5^5 thing because 5 is the number of half-lives (x) and 0.5 is the rate of loss (or whatever its called).
If it were to gain, you would put 1.5
25d^2-30d-35d+42=25d^2-65d+42.
Answer:
52 × 2 - 31 = 73
Step-by-step explanation:
Use PEMDAS
The way I remember is like this..
Please (Parentheses)
Excuse (Exponents)
My (Multiication)
Dear (Division)
Aunt (Addition)
Sally (Subtraction)
Multiply 52 × 2
which gives you 104.
Then subtract 31 from 101
and that will give you 73.
Answer:
Hence, the value of y is undefined.
Step-by-step explanation
from the property, log_a (b) = (log(a))/log(b).
The value log (-7) was not defined. So, the entire log value also not defined.
Hence, the value of y is undefined.
