The sum of two rational numbers is -2. If one of the numbers is -14/5, find the other.
Marat540 [252]

Answer:

\frac{4}{5}

Step-by-step explanation:

\frac{ - 14}{5}  + x =  - 2 \\ x =  - 2 +  \frac{14}{5 }  \\ x =  \frac{ - 10 + 14}{5}  \\ \: x =  \frac{4}{5}  \\ therefore \: the \: other \: number \: is \:  \frac{4}{5}

The projectile motion of an object can be modeled using s(t)=gt^2+v0t+s0, where g is the acceleration due to gravity, t is the t
RSB [31]

Answer:

S(t) = -4.9t^2 + Vot + 282.24

Step-by-step explanation:

Since the rocket is launched from the ground, So = 0 and S(t) = 0

Using s(t)=gt^2+v0t+s0 to get time t

Where g acceleration due to gravity = -4.9m/s^2. and

initial velocity = 39.2 m/a

0 = -4.9t2 + 39.2t

4.9t = 39.2

t = 8s

Substitute t in the model equation

S(t) = -49(8^2) + 3.92(8) + So

Let S(t) =0

0 = - 313.6 + 31.36 + So

So = 282.24m

The equation that can be used to model the height of the rocket after t seconds will be:

S(t) = -4.9t^2 + Vot + 282.24
