Answer:
-3.85 feet
Step-by-step explanation:
-2.8 feet + 1/2(2.1) = 1.05 as the stream is more than previous then we must subtract to find previous = -2.8 - 1.05 = -3.85 feet
x=12
1/2
We first find the least common multiple, which is 6. Therefore, we can multiply 1/3 x 2/2 (since 2/2 is equal to one and won't change the final amount) and get 2/6. 2/6+1/6=3/6, or 1/2.
f(x)=-3x^2-1
f(-2)= -3(-2)²-1=-3·4-1= - 13
