Answer:

104.8cm³(1 decimal place)

Step-by-step explanation:

Volume of a cone is given by the formula

V=1/3πr²h

we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7

V=1/3× 22/7×5²×4

V=1/3 × 22/7 ×25 ×4

V=2200/21

V=104.76190476

V=104.8cm³(1decimal place)

pls if you like this answer you can appreciate it by marking it as brainliest

Solve the system of equations.<br><br> −4x+3y=−2<br> y=x−1<br><br> x-<br> y-<br> ​
Kobotan [32]

Answer: x=  -1

               y= -2

Step-by-step explanation:

-4x+3y= -2

y=x-1

-------------------

-4x+3(x-1)= -2

-4x+3x-3= -2

-x=1

x= -1

y=-1-1

y=-2

Answer:

For (2x^2 + 8x - 8), the group is CLOSED as it a polynomial.

Step-by-step explanation:

Here, the given polynomials are:

P(x)=(5x^2+2x-6)\\Q(x)=(3x^2-6x+2)

Now, a group G is said to be <u>CLOSED UNDER SUBTRACTION</u> if,

a and b are he elements of G ⇒ (a-b) is ALSO AN ELEMENT of G

Now, here:

R(x)  = P(x) - Q(x) = (5x^2+2x-6) - (3x^2-6x+2) = (2x^2 + 8x - 8)

or, R(x)  = (2x^2 + 8x - 8)

Also, R(x) is a POLYNOMIAL.

So, R(x) is an Element of group G.

So, the set G of polynomials.

Hence, for the polynomial  (2x^2 + 8x - 8), it will be a polynomial the group is CLOSED.
