A rectangular park is 50 meters wide and 90 meters long. Give the length and width of another rectangular park that has the same

larisa [96]

Answer:

$l = 100\,m$ and $w = 40\,m$

Step-by-step explanation:

The formulas for the area and perimeter of a rectangle are, respectively:

$A = w\cdot l$

$p = 2\cdot (w + l)$

The perimeter is equal to:

$p = 2\cdot (50\,m + 90\,m)$

$p = 280\,m$

Area is likewise equal to:

$A = (50\,m)\cdot (90\,m)$

$A = 4500\,m^{2}$

Then, equations are now described:

$A = w \cdot l$

$140\,m = w + l$

Likewise, the equation of area is simplified afterwards:

$A = (140\,m - l)\cdot l$

$A = 140\cdot l - l^{2}$

The area is reduced inasmuch as length is increased. Let assume that length is 100 meters. The length and width are described herein:

$l = 100\,m$ and $w = 40\,m$

The average low temperature by month in Nashville is represented by the function

malfutka [58]

Answer:

Step-by-step explanation:

Given the average low temperature by month in Nashville is represented by the function f(x)=-1.4x² + 19x +1.7, where x is the month, the average rate of change is expressed as d[f(x)]/dx = 2(1.4x) + 19

d[f(x)]/dx = 2.8x + 19

Since the number of months between March and August is 5 months and x is in months, hence we will substitute x = 5 into the resulting function to get the average rate of change from March to August as shown;

d[f(x)]/dx at x = 5

= 2.8(5)+ 19

= 14 + 19

= 33

<em>Hence the average rate of change from March to August is 33</em>
