The Gradient would be negative therefore making it start by going down then up, making a sad mouth. the x intercepts will be the same. Frankly it just flipped upside down. I remember it like if the gradient is positive then happy smile, if its negative then sad smile. Hope I helped.

Use the table at the right.<br> a. What is the approximate volume of the small truck?
irina [24]

Volume of the small truck = 554.54 cubic ft

Solution:

Given data:

Length of the small truck = 11\frac{1}{13} ft

Width of the small truck = 7\frac{5}{12} ft

Height of the small truck = 6\frac{3}{4} ft

Volume of the small truck = length × width × height

                                           $=11\frac{1}{13}\times7\frac{5}{12}\times 6\frac{3}{4}

Let us change the mixed fraction into improper fraction.

                                          $=\frac{11\times 13 + 1}{13}\times\frac{7 \times 12 + 5}{12}\times \frac{6 \times 4 + 3}{4}

                                          $=\frac{144}{13}\times\frac{89}{12}\times \frac{27}{4}

                                          $=\frac{7209}{13}

                                          = 554. 54 cubic ft

Volume of the small truck = 554.54 cubic ft
