Answer:
The following are some inequalities that represent the possible position of the playground.
2x ≥ -2 and x < -3
x + 3 ≤ 1 and –x > -3
x + 4 ≤ 2 and x + 4 > 7
2x – 1 ≥ -5 and 3x < 9
The city council planning for playground, that is more than 5 blocks from fountain and at least 2 blocks from center of park.
A solid dot on negative two points less than -2 and a circle dot on positive three points in the direction indicating greater than 3. So the right inequality is x + 3 ≤ 1 and –x > -3. That represents the possible position of ground.
Hence, the inequality x + 3 ≤ 1 and –x > -3 is the playground's possible position.

Answer:
The value of
is
.
Step-by-step explanation:
The given equation is

We need to find the value of
.
Differentiate with respect to t.
![[\because \frac{d}{dx}x^n=nx^{n-1},\frac{d}{dx}C=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cfrac%7Bd%7D%7Bdx%7Dx%5En%3Dnx%5E%7Bn-1%7D%2C%5Cfrac%7Bd%7D%7Bdx%7DC%3D0%5D)

It is given that y=2 and dy/dt=1, substitute these values in the above equation.



Divide both sides by 4x³.


Therefore the value of
is
.
It’s impossible what are you doing Distributed property or solving for x?
Answer:

Step-by-step explanation:
Given that,
The side of an equilateral prism = 4 cm
The altitude of the prism = 5 cm
We need to find the volume of the prism. The formula for the volume of a prism is as follows :

Where
A is the area of equilateral triangle, 
So,

So, the volume of the prism is equal to
.
