How should the principal round to estimate how much more money the school needs to meet its goal? Explain.

Evaluate the expression without using a calculator. \( \log 1000 \) \( \log 1000=\square \)

a) \( \mathrm{F}(\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D})=\sum(0,1,2.3,4,6,7,8,9,10,15) \) b) \( \mathrm{F}(\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D})=\sum(0,4,6,8,9,11,11,14,15) \)

\( \frac { 80 } { 50 } = - = - \)

Evalúa \( a+(-b) \), donde \( a=4 \) y \( b=2 \). \( \square \)

Question 16 The polynomial function \( f \) is defined by \( f(x)=-3 x^{4}-7 x^{3}+3 x^{2}+9 x-1 \). Use the ALEKS graphing calculator to find all the points \( (x, f(x)) \) where there is a local minimum. Round to the nearest hundredth. If there is more than one point, enter them using the "and" button. \( (x, f(x))=\left(\prod_{1}, \square\right) \)
