Instantaneous velocity represents the velocity at a particular point.

The instantaneous velocity at t = 3 is 7.7 ft/s

The table is given as:

$\left[\begin{array}{cccccccc}t&0&1&2&3&4&5&6\\s&0&4.9&10.7&23.2&50.4&109.4&237.8\end{array}\right]$

To calculate the instantaneous velocity at $t = 0$

We get the distance at $t = 3$

At $t = 3$ , the distance (s) is:

$s = 23.2$

So, the instantaneous velocity (v) is:

$v = \frac st$

This gives

$v = \frac{23.2}3$

Divide 23.2 by 3

$v = 7.7$

Hence, the instantaneous velocity at t = 3 is 7.7 ft/s

What’s the correct answer for this ? Two chords AB and CD intersect at E. If AE = 2cm, EB =4, and CE = 2.5 cm, find the length o

ss7ja [257]

Answer:

ED = 3.2 cm

Step-by-step explanation:

According to chord-chord power theorem,

(AE)(EB) = (CE)(ED)

2*4 = 2.5 *ED

8/2.5 = ED

ED = 3.2 cm

The lifetimes of 10,000 watch batteries are normally distributed the mean lifetime is 500 days the standard deviation is 60 days

Lelu [443]

Given:
μ = 500 days, the population mean
σ = 60 days, the population standard deviation

Therefore
μ + σ = 560
μ - σ = 440
μ + 2σ = 620
μ - 2σ = 380
μ + 3σ = 680
μ - 3σ = 320

The figure shown below illustrates the normal distribution
About 68% of the total area lies in x = (μ-σ, μ+σ)
About 95% of the total area lies in x = (μ-2σ, μ+2σ)
About 99.7% of the total area lies in x = (μ-3σ, μ+3σ).
