Answer:
She applied the exponent -2 to 4(-2) instead of applying the exponent to just -2.
Step-by-step explanation:
i got my rerecord from my flash cards my teacher made of some answers
• First way to solve:
We'll manipulate the expression of the equation:

If we have y=0:

Then, the function has one real zero (x=3) and two imaginary zeros (4i and -4i).
Answer: B
• Second way to solve:
The degree of the function is 3. So, the function has 3 complex zeros.
Since the coefficients of the function are reals, the imaginary roots are in a even number (a imaginary number and its conjugated)
The function "has only one non-repeated x-intercept", then there is only one real zero.
The number of zeros is 3 and there is 1 real zero. So, there are 2 imaginary zeros.
Answer: B.
Answer:
The t-shirt cost $10.70
Step-by-step explanation:
12.25 + T = 22.95
-12.25 -12.25
T=10.70
Answer:
In the year 2010
Step-by-step explanation:
we have

where
A is the population in thousands
t is the number of years since 1998
so
For A=297 thousands
substitute and solve for t

simplify

Apply ln both sides
![ln(1.485)=ln[e^{0.033t}]](https://tex.z-dn.net/?f=ln%281.485%29%3Dln%5Be%5E%7B0.033t%7D%5D)

Remember that




1998+12=2010
If the first part is V=1/3 of Bh, then B=27
