17) Suppose you build an architectural model of a new concert hall using a scale factor of 19. How will the surface area of the actual concert hall compare to the surface area of the scale model?

Chapter 3 Home Investematic Investigation 1. With an adult, make a plan to systematically observe which stars are visible in an area of the sky over a period of two weeks. 2. Fill in the dates and times when you will observe the sky (first column). 3. Go outside and choose an area of the sky that you would like to investigate. Choose an area that is near a reference point (a telephone pole, a building, or a tree), so you can be sure you are looking at the so area every time. Draw the stars you see and the reference point for th and every observation that follows (second column).

An exponential function has a domain \( (-\infty, \infty) \) and range \( (4, \infty) \). What is the domain and range of its inverse? Domain of the inverse \( =\square \) Range of the inverse \( =\square \)

Let \( P(x)=2 x^{4}+a x^{2}-5 x-7 \). If \( P(3)=68 \), determine the value of \( P(x)=x^{4}+x^{3}-2 x+c \). If \( P(1)=6 \), determine the value of d Let \( P(x)=3 x^{6}-5 x^{3}+a x^{2}+b x+10 \). If \( P(-1)=P(2)=0 \), find the values of
