Answer:
the answer is 2
Step-by-step explanation:
<span>Using processing software (Excel) or even a decent scientific calculator. You input the values and generate the best fit cubic equation.
For number 1, the equation is
y = 8x10</span>⁻⁵ x³ - 0.0097 x² + 0.374 x + 1.083
where x is the number of years since 1900
y is the pounds cheese consumed
For number 2, the equation is
y = -3x10⁻⁵ x³ + 0.0028 x² + 0.2155 x + 1.7736
For number 3
P(-1) = 18
I'm not to sure maybe b ?
2^7b = 2^5
Now you have like bases. This means that you can set the exponents equal , meaning 7b= 5. B =5\7
T=2
t^2=4
4-4=0
is that right?
