MODELING WITH MATHEMATICS A farmer plants a garden that contains corn and pumpkins. The total area (in square

laiz [17]

Answer:

The equation in standard form that models area of pumpkins is:

$A_p = A_G - A_c$

and the area is: $x^2+8x+2$

Step-by-step explanation:

Given that the garden has corn and pumpkins

The expressions are:

Total area of garden: $A_G = 2x^2+5x+4$

Area of Corn: $A_c = x^2-3x+2$

Area of Pumpkins: $A_p = ?$

The sum of areas of corn and pumpkins is the total area of the garden.

It can be expressed mathematically as:

$A_G = A_c+A_p$

If we have to find the area of pumpkins,

$A_p = A_G - A_c$

Putting the values

$A_p = (2x^2+5x+4) - (x^2-3x+2)\\A_p = 2x^2+5x+4-x^2+3x-2\\A_p = 2x^2-x^2+5x+3x+4-2\\A_p = x^2+8x+2$

The equation in standard form that models area of pumpkins is:

$A_p = A_G - A_c$

and the area is: $x^2+8x+2$

$363.9ft^{2}$

Step-by-step explanation:

$Area =\pi r^{2} -\frac{1}{3}\pi r^{2} +\frac{1}{2}r^{2}sin\alpha \\\\\\ = \frac{2}{3}\pi 12^{2} +\frac{1}{2}12^{2}sin120 =363.9ft^{2}$

A kitchen drawer has a Volume 1,125 cubic inches. The drawer is 15 inches long and 5 inches deep. What is the width of the drawe

Temka [501]

Answer:

The width of the drawer is $15\ in$

Step-by-step explanation:

we know that

The volume of the drawer is equal to

$V=LWH$

we have

$L=15\ in$

$H=5\ in$ -----> the deep of the drawer

$V=1,125\ in^{3}$

substitute the given values in the formula and solve for W

$1,125=(15)(W)(5)$

$1,125=(75)(W)$

$W=1,125/(75)$

$W=15\ in$
