(a) The position of a particle at time t is s(t) = t^3 + t. Compute the average velocity over the time interval [7, 12].(b) Esti

ryzh [129]

Answer:

<h2>a) Average velocity = 278 units</h2><h2>b) Instantaneous velocity at t = 7 seconds is 148 units</h2>

Step-by-step explanation:

a) Average velocity is the ratio of displacement to time.

We have

s(t) = t³ + t

t is in between 7 and 12

s(7) = 7³ + 7 = 350

s(12) = 12³ + 12 = 1740

Displacement = 1740 - 350 = 1390

Time = 12 - 7 = 5

Displacement = Average velocity x time

1390 = Average velocity x 5

Average velocity = 278 units

b) s(t) = t³ + t

Differentiating

v(t) = 3t² + 1

At t = 7

v(t) = 3 x 7² + 1 = 148 units

Instantaneous velocity at t = 7 seconds is 148 units

JulijaS [17]

Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease

<em><u>Solution:</u></em>

Given that Barry found a computer at Staples for $989

A week later, the computer went on sale for $849

To find: percent of change

Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.

<em><u>THE PERCENT CHANGE IS GIVEN AS:</u></em>

$\text{ percent change } =\frac{\text { final value - initial value }}{\text { initial value }} \times 100$

If the result is positive, it is percentage increase

If the result is negative, it is percentage decrease

Here initial value = 989 and final value = 849

Substituting the values in above formula,

$\begin{aligned}&\text { percent change }=\frac{849-989}{989} \times 100\\\\&\text { percent change }=-0.14155 \times 100=-14.156 \%\end{aligned}$

Here negative sign denotes percentage decrease

Thus percentage change is 14.156 % decrease
