olive's garden in only 10y2 and the watermelon plants she wants to grow required 2.5y2 each.how many watermelon plants can she g

DerKrebs [107]

Answer:

4 plants

Step-by-step explanation:

In this problem, we are given the total area of the garden, which is:

$A=10y^2$

The number of plants that can fit inside the garden is given by the equation:

$A=na$

where:

n is the number of plants

a is the area of each plants

In this problem, the area of each plant is

$a=2.5y^2$

Therefore, we can re-arrange the equation to find the number of plants that can fit:

$n=\frac{A}{a}=\frac{10}{2.5}=4$

fomenos

Answer: It will take 4 seconds for the rock to hit the water.

Step-by-step explanation:

Given : Benjamin threw a rock straight up from a cliff that was 48 ft above the water.

If the height of the rock h, in feet, after t seconds is given by the equation

$h = -16 t^2+ 52 t + 48$

To find : Time taken for the rock to hit the water.

When rock hit the water height becomes zero , i.e. put h = 0 , we get

$-16 t^2+ 52 t + 48 =0$

Divide equation by 2 , we get

$-8t^2+26t+24=0$

The Laue of x for ax²+bx+c =0 is $x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}$

So , $t=\frac{-26\pm\sqrt{(26^{2}-4(-8)(24))}}{2(-8)}$

$t=\dfrac{-26\pm 38}{-16}\\\\ t=-\dfrac{-26+38}{-16}=-0.75\ \ t=\dfrac{-26-38}{-16}=4$

Since t cannot be negative , so t= 4

Hence, it will take 4 seconds for the rock to hit the water.
