I'd say it is 100 but I'm not sure.

I'd say 110 because if you take one X from each end repeatedly until you get to the last column of X's its in the 110 column

A pine cone drops from a tree branch that is 36 feet above the ground. The function h = –16t2 + 36 is used. If the height h of t

scoray [572]

Notice that the height of the pine cone when it hits the ground is zero. So, to find the tame it takes for the pine cone to hit the ground, we just need to replace the height, $h$ , with 0 in the function, and solve for time $t$ :
$h=-16t^2+36$
$0=-16t^2+36$
$-36=-16t^2$
$t^2= \frac{-36}{-16}$
$t^2= \frac{9}{4}$
$t=(+/-) \sqrt{ \frac{9}{4} }$
$t=(+/-) \frac{3}{2}$
$t=(+/-)1.5$
Since time cannot be negative, the solution is $t=1.5$ seconds.

Since 1.5 second is significantly less than 2 seconds, we can conclude that <span>2 seconds is not a reasonable answer to this model.</span>

What polynomial when divided by 2y^5 yields 4y^2-2y+9 as a quotient?

Sedbober [7]

$w(x):2y^5=4y^2-2y+9\Rightarrow w(x)=2y^5(4y^2-2y+9)\\\\w(x)=2y^5\cdot4y^2-2y^5\cdot2y+2y^5\cdot9\\\\w(x)=8y^7-4y^6+18y^5$
