Zachary's cornfields are irrigated in circular regions. Zachary records data on the com production from various irrigated circul

marin [14]

Answer:

D. about 5,000 ft

Step-by-step explanation:

Given the equation: $f(x)=0.01x^2+x+0.2$

We want to estimate what radius Zachary would need to irrigate 250,000 bushels of corn.

Substituting f(x)=5000, we have

$250000=0.01x^2+x+0.2\\0.01x^2+x+0.2-250000=0\\0.01x^2+x-249999.8=0$

Using the quadratic formula

$x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}$

$a=0.01, b=1, c=-249999.8\\x=\dfrac{-1\pm\sqrt{1^2-4(0.01)(-249999.8)} }{2(0.01)}\\=\dfrac{-1\pm\sqrt{1+9999.992} }{0.02}\\=\dfrac{-1\pm\sqrt{10000.992} }{0.02}\\x\approx \dfrac{-1\pm100 }{0.02}\\x\approx \dfrac{-1+100 }{0.02}\: or\:\dfrac{-1-100 }{0.02}\\\\x\approx4950\: or\: -5050 \\$Therefore x\approx 5000ft$

The correct option is D

What is the area of the polygon?

Delvig [45]

Find the area of the triangle on top
A=(.5)(Base)(Height)
A=(.5)(15)(9)
A=67.5

In the rhombus below you can move the corner triangle to the other side to transform it into a rectangle with a sides of 7 and 15. so lets find the area of this rectangle
A=L*W
A=15*7
A=105

now combine the two areas
67.5+105
172.5
so answer "C"
