The first graph is a perfect graph for this representation, from he graph we can conclude that sales were following exponential function. This can be seen by drawing a smooth trend line cutting the plotted points. Hence, this implies that the future sales can be estimated using exponential functions.

A track and field playing area is in the shape of a rectangle with semicircles at each end. See the figure. The inside perimeter

Schach [20]

Answer:

Step-by-step explanation:

Let x be the track straights lengths

Let y be the track ends diameter and the other rectangle side lengths.

1800 = 2x + πy

y = (1800 - 2x) / π

A = xy

A = x((1800 - 2x) / π

A = (1/π)(1800x - 2x²)

dA/dx = (1/π)(1800 - 4x)

0 = (1/π)(1800 - 4x)

0 = 1800 - 4x

4x = 1800

x = 450 m

y = (1800 - 2(450)) / π

y = 900/π or approximately 286.5 m

A store had 4 boxes of video games. How many days in total would it take to sell all of the games if each day they sold 3/5 of a

Klio2033 [76]

52 is what percent of 260

chubhunter [2.5K]

if we take 260 to be the 100%, what is 52 off of it as a percentage?

$\bf \begin{array}{ccll} amount&\$\\ \cline{1-2} 260&100\\ 52&x \end{array}\implies \cfrac{260}{52}=\cfrac{100}{x}\implies 5=\cfrac{100}{x} \\\\\\ 5x=100\implies x = \cfrac{100}{5}\implies x=20$
