leonid [27]

Answer:

The maximum height of the particle is 100 ft

A is correct

Step-by-step explanation:

A particle is moving along a projectile path where the initial height is 96 feet with an initial speed of 16 feet per second.

The standard equation of parabolic projectile.

$h(t)=-16t^2+v_0t+h_0$

where,

$v_0=16\ ft/s$

$h_0=96\ ft$

$h(t)=-16t^2+16t+96$

So, we get the parabolic equation of path.

The maximum value at vertex.

$t=-\dfrac{b}{2a}$

$t=-\dfrac{16}{-32}=\dfrac{1}{2}$

Maximum at t=0.5

$h(0.5)=-16(0.5)^2+16(0.5)+96$

$h(0.5)=100$

Hence, The maximum height of the particle is 100 ft

3. The sum of the second term and the ninth term of an arithmetic sequence is -5. The sum of the third and fourth terms of the s

GaryK [48]

Answer:

First term of the sequence is $11$

Step-by-step explanation:

Let $a$ be the first term and $d$ be the common difference

We have

The sum of the second term and the ninth term of an arithmetic sequence is $-5$

$a+(2-1)d+a+(9-1)d=-5\\\\2a+9d=-5---eqn1$

The sum of the third and fourth terms of the same sequence is $7$

$a+(3-1)d+a+(4-1)d=7\\\\2a+5d=7---eqn2$

eqn 1 - eq2

$4d=-12\\\\d=-3$

Substituting in eqn 1

$2a+9\times -3=-5\\\\2a=22\\\\a=11$

First term of the sequence is $11$
