To divide fraction multiply the first fraction by the reciprocal of the second fraction:

7/4 x 7/8 = (7x7) / (4x8) = 49/32

Identify the vertex for the graph of y = −2x2 − 12x 1.

RUDIKE [14]

Answer: (-3,19)

Step-by-step explanation:

Here the given function is,

$y = -2x^2-12x+1$

$\implies y = -2(x^2+6x)+1$

$\implies y = -2(x^2+6x)+1+18-18$

$\implies y = -2(x^2+6x+9)+19$

$\implies y = -2(x+3)^2+19$

$\implies y = -2(x-(-3))^2+19$

Since, the standard equation of a quadratic function is $y = a(x - h)^2 + k$

Where (h,k) is the vertex of the function.

On comparing the equation of given function with this standard form,

We get, the vertex of the given function is (-3,19)

⇒ First option is correct.

What are the dimensions of the lightest open-top right circular cylindrical can that will hold a volume of 2744 cmcubed3?

nata0808 [166]

Answer:

r=2.808cm h = 100cm

then we get volume of cylinder that is 2744 As explained below

Step-by-step explanation:

Volume of cylinder = πr²h

Surface area of cylinder = 2πrh +πr² (1)

h= 2744 /πr²

put value oh h in equation (1)

Area =[2πr] 2744 /πr²

=[5488/r +πr²]

dA/dx=0

i.e 2πr=5488/r²

Solving this r.r= ∛5488/2π

=2.808

taking second derivation we get 100
