F(x)=2/3x+9x<br> What is the value of f(12)?

andreev551 [17]

Answer:

116

Step-by-step explanation:

To find f(12), plug in 12 as x in the equation:

f(x) = 2/3x + 9x

f(12) = 2/3(12) + 9(12)

f(12) = 8 + 108

= 116

So, f(12) = 116

a ball is thrown into the air with an upward velocity of 36 ft/s. it’s height h in feet after t seconds is given by the function

lukranit [14]

Complete the square:

$h(t)=-16t^2+36t+9=-16\left(t^2-\dfrac94t\right)+9=-16\left(\left(t-\dfrac98\right)^2-\dfrac{81}{64}\right)+9$

$h(t)=-16\left(t-\dfrac98\right)^2+\dfrac{117}4$

That is, the graph of $h(t)$ is a parabola with vertex at $(t,h(t))=\left(\dfrac98,\dfrac{117}4\right)$ , meaning the ball reaches its maximum height of $\dfrac{117}4=29.25\,\mathrm{ft}$ after $t=\dfrac98=1.125\,\mathrm s$ of being thrown.

I think Y is 4 because the only time a number squared is the number by it'self is also the number +2 is 2- and that makes x=2
