That's D. n² ÷ 5 because it says the division of n squared and 5.

Joe wants to enlarge the rectangular pumpkin patch located on his farm. The pumpkin patch is currently 40 meters wide and 60 met

vodomira [7]

Answer:

$15x^2+380x+2400$

The diagram is shown below for reference.

Step-by-step explanation:

We are given the length and width of old pumpkin patch as $60$ meters and $40$ meters respectively.

It further says length is increased by $5x$ meters and width increased by $5x$ meters.

So the length of the new pumpkin patch would be $60+5x$ meters.

And the width would be $40+3x$ meters.

We know area of a rectangular shape $=length \times width$

So, plugging the above values, we get the area of the new pumpkin patch as:

$=(60+5x)\times (40+3x)\\=2400+180x+200x+15x^2\\=2400+380x+15x^2\\=15x^2+380x+2400$ on rearranging.

Thus the function of the area of the new pumpkin patch would be:

$f(x) = 15x^2+380x+2400$

A culture started with 3000 bacteria. After 4 hours, it grew to 3,600 bacteria. Predict how many bacteria will be present after

Vlad [161]

Hello Shannonrodrigue. You can solve this by setting up an exponential growth equation.

$A = A_ob^t$
$3600 = 3000b^4$

Now we solve for b
$3600 = 3000b^4$
$\frac{3600}{3000} = \frac{3000b^{4}}{3000}$
$\frac{6}{5} = b^4$
$\sqrt[4]{\frac{6}{5}} = \sqrt[4]{b^4}$
$\sqrt[4]{\frac{6}{5}} = b$

Now that we have found b, we can use the equation $A = 3000b^t$ to predict how many bacteria will be present after 10 hours.
$b = \sqrt[4]{\frac{6}{5}}$
t = 10
$A = 3000b^t$
$A = 3000\sqrt[4]{\frac{6}{5}}^{10} = 4732.3228 = 4732$

Answer = 4732
