The position of an object at time t is given by s(t) = 6 - 14t. Find the instantaneous velocity at t = 6 by finding the derivati
nikdorinn [45]

Answer:

<em>It results -14 in either way</em>

Step-by-step explanation:

<u>Velocity As A Rate Of Change </u>

The velocity of an object can be computed as the rate of change of its displacement (or position taken as a vector) over time. If we compute it as a derivative, it's called instantaneous velocity, and if computed as the slope of the function (difference quotient) at a certain point it's the average velocity

The position of the object as a function of time is

\displaystyle s(t)=6-14t

Computing the derivative

\displaystyle s'(t)=-14

We can see it's a constant value. If we use the slope or rate of change:

\displaystyle v=\frac{s_2-s_1}{t_2-t_1}

Now let's fix two values for time  

\displaystyle t_1=5\ sec,\ t_2=8\ sec

and compute the corresponding positions, by using the given function

\displaystyle s_1=6-14(5)=-64

\displaystyle s_2=6-14(8)=-106

Now we compute the average velocity

\displaystyle v=\frac{-106-(-64)}{8-5}

\displaystyle v=\frac{-106+64}{3}=\frac{-42}{3}

\displaystyle v=-14

We get the very same result in both ways to compute v. It happens because the position is related with time as a linear function, it's called a constant velocity motion.

Find the length of the missing side. The triangle is not drawn to scale.
Oksana_A [137]

Answer:

b=8

Step-by-step explanation:

This is a right triangle, as we can see from the box in the corner.

We can use Pythagorean theorem to find the unknown side

a^2 +b^2 = c^2

where a and b are the legs and c is the hypotenuse

15^2 +b^2 = 17^2

225 + b^2 =289

Subtract 225 from each side

225-225 + b^2 = 289-225

b^2 =64

Take the square root of each side

sqrt(b^2) = sqrt(64)

b = 8

tensa zangetsu [6.8K]

Answer:

6 hours

Step-by-step explanation:

Research is 5%, Games is 25%, so the diffrence is 20%

20%  of 30 hours = 30 x2/10 = 6 hours

Tremaine played 6 hours more video games than research.
