The length of one base of a trapezoid is 19 less than five times the length of the other base. If the trapezoid has a height of

RoseWind [281]

The length of longer base is 41 feet

<em><u>Solution:</u></em>

<em><u>The area of trapezoid is given as:</u></em>

$A = \frac{a+b}{2} \times h$

Where , "a" and "b" is the length of base and "h" is the height

The length of one base of a trapezoid is 19 less than five times the length of the other base

a = 19 less than fives times b

a = 5b - 19

Height of 18 feet and an area of 477 ft squared

h = 18 feet

area = 477 square feet

<em><u>Substitute the values in above formula</u></em>

$477=\frac{5 b-19+b}{2} \times 18\\\\477=(6b-19) \times 9\\\\477 = 54b-171\\\\54b = 648\\\\b=12$

Therefore,

a = 5b - 19 = 5(12) - 19 = 41

Thus length of longer base is 41 feet

Write the equation of a function that passes through<br> these points.

Ugo [173]

to get the equation of any straight line, we simply need two points off of it, let's use the ones in the picture below.

$(\stackrel{x_1}{1}~,~\stackrel{y_1}{9})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{13}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{13}-\stackrel{y1}{9}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{1}}}\implies \cfrac{4}{2}\implies 2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{9}=\stackrel{m}{2}(x-\stackrel{x_1}{1}) \\\\\\ y-9=2x-2\implies y=2x+7$
