Answer:

-8x^6+4x^5

Step-by-step explanation:

Note that the dot means multiplication... which means that we will have to multiply the whole values given

So let's solve

(-4).x^4.(2x^2-x)

So let's get to work

(-4).(2x^6-x^5)

So let's continue

-8x^6+4x^5

Therefore the final answer is -8x^6+4x^5

Answer:

Time to land on 11ft is 4.25 seconds

Step-by-step explanation:

Given

$y = 300 - 16t^2$

Required

Solve for t when height is 11ft

This implies that $y = 11$

So: substitute 11 for y in $y = 300 - 16t^2$

$11 = 300 - 16t^2$

Collect Like Terms

$16t^2 = 300 - 11$

$16t^2 = 289$

Express both sides as squares

$4^2 * t^2 = 17^2$

$(4t)^2 = 17^2$

Take square roots of both sides (ignore negative)

$4t = 17$

Solve for t

$t = \frac{17}{4}$

$t = 4.25$

Hence, time to land on 11ft is 4.25 seconds
