Rewrite the function f (x) =-3(x + 2)2 + 7 in the form f(x) = ax++bx+c.
kondaur [170]

Answer:

f(x)= -3x² - 12x - 5

Step-by-step explanation:

-3(x+2)² + 7

-3(x+2)(x+2) + 7

(-3x-6)(x+2) + 7

-3x² - 6x - 6x - 12 + 7

-3x² - 12x - 5

The volume of a sphere is 4,500π cubic yards. What is the radius of the sphere?
algol [13]

Answer:

  • 15

Step-by-step explanation:

In the question it is given that the volume of a sphere is 4,500π cubic yards. And we have to find the radius.

We know that,

  • 4/3πr³ = Volume of a sphere

Now, Substituting the values in the fomulae :

⇒ 4/3πr³ = 4500π

Cancelling π from both sides :

⇒ 4/3r³ = 4500

⇒ 4r³ = 4500 × 3

⇒ 4r³ = 13500

⇒ r³ = 13500/4

⇒ r³ = 3375

Taking cube root on both sides we get :

⇒ r = 15

Therefore,

  • <u>The radius of the sphere is 15 yards</u>

Answer:

<h2>x =  -  \frac{19}{4}</h2>

Option B is the correct option.

Step-by-step explanation:

-  \frac{1}{2}  + x =  -  \frac{21}{4}

Move constant to R.H.S and change its sign:

x =  -  \frac{21}{4}  +  \frac{1}{2}

Take the L.C.M

x =  \frac{ - 21 + 1  \times 2}{4}

x =  \frac{ - 21 + 2}{4}

Calculate

x =  -  \frac{19}{4}

Hope this helps...

Good luck on your assignment..
