Answer:

  • B. g(t) = -16t² + 80t

Step-by-step explanation:

<u>Given function:</u>

  • g(t) = -16t² + vt + h

A model rocket is launched off the ground at an initial velocity of 80 feet per second.

<u>This gives us </u>

  • h = 0 and v = 80

<u>The function becomes:</u>

  • g(t) = -16t² + 80t

Can some one please do this? thank you !

Answer:

Step-by-step explanation:

6)a)

5\sqrt{27}=5\sqrt{3*3*3}\\\\ =5*3\sqrt{3}\\\\ =15\sqrt{3}

7a) y² - 5y - 14 =  y² -7y +2y - 2*7

                       = y*(y - 7) + 2*(y - 7)

                        =(y - 7)(y + 2)

b) Use FOIL method

(2\sqrt{5}+1)(3\sqrt{5}-1)=(2\sqrt{5}*3\sqrt{5})-((2\sqrt{5}*1)+1*3\sqrt{5})-1*1\\\\ =6*5-2\sqrt{5}+3\sqrt{5}-1\\\\  =30+(-2+3)\sqrt{5}-1\\ \\=29+\sqrt{5}

c) Rationalize the denominator by multiplying the denominator and numerator by √12

\frac{6}{\sqrt{12}}=\frac{6*\sqrt{12}}{\sqrt{12}*\sqrt{12}}\\\\=\frac{6\sqrt{2*2*3}}{12}\\\\=\frac{6*2\sqrt{3}}{12}\\\\=\frac{12\sqrt{3}}{12}\\\\=\sqrt{3}
