If an archer shoots an arrow straight upward with an initial velocity of 160

HACTEHA [7]

Answer:

maximum height of the arrow will be 408 m

Step-by-step explanation:

We have given the function of height as $h(t)=-16t^2+160t+8$

We know that first derivative of height will be velocity

So first derivative of height

$\frac{dh}{dt}=-32t+160$

$v(t)=-32t+160$

We know that at maximum height velocity will be zero

$-32t+160=0$

t = 5 sec

Sp arrow will be at maximum height at t = 5 sec

So height at t = 5 sec will be

$h(5)=-16\times 5^2+160\times 5+8=408m$

So maximum height of the arrow will be 408 m

Solve for X. 20 points !!!!

GarryVolchara [31]

Answer:

4) x = - 12

5) x = 4

Step-by-step explanation:

Since points T and S are mid points of sides ML and MN of triangle MLN.

Therefore, by mid point theorem,

TS is half of LN

so,

$x + 26 = \frac{1}{2} (x + 40) \\ \\ 2(x + 26) =x + 40 \\ \\ 2x + 52 = x + 40 \\ \\ 2x - x = 40 - 52 \\ \\ x = - 12$

5) In the same way x = 4 will be the correct answer in question number 5.
