Answer:
44
Step-by-step explanation:
The function formula is given as
f(x) = 4(1 – x)
To find the f(-10) we will substitute into the function formula, then we have
f(-10)= 4[1-(-10)]
=4[11]
=44
Hence, the value of f(-10)= 44
To find the number of half lives divide the total number of days by the number of days for 1 half live:
1104 / 138 = 8
There are 8 half lives.
To find the total amount left multiply the starting amount by 1/2 to the 8th power:
38 * 0.5^8 = 0.148 = 0.15 grams
The answer is the last one.
The new coordinates should be P= (-7, -8) O= (5, -7) and W= (-2,-4). Graph those points and you have your reflected triangle! I hope this helps!!
