Result:

The information at hand includes:

The acceleration stands at 3.2 m/s² for a duration of 14 seconds.

Initial velocity is 5.1 m/s.

Starting position is 0m.

Therefore:

A(t) = 3.2m/s²

To derive the velocity, integration over time is performed where the constant of integration equals the initial velocity.

V(t) = (3.2m/s²)*t + 5.1 m/s

For the position equation, we integrate again over time, with the integration constant being the initial position (which is zero).

P(t) = (1/2)*(3.2 m/s²)*t² + 5.1m/s*t

The final position corresponds to when the car ceases to accelerate, occurring at t = 14s.

P(14s) =   (1/2)*(3.2 m/s²)*(14s)² + 5.1m/s*14s = 385m

Thus, the final position is 385 meters from the starting point.

Below is an attempt to derive the derivative of sec(x) using product rule, where x is in the domain of secx. In which step, if a
tester [12383]

The mistake is present in step 3. According to the product rule, we find

\dfrac{\mathrm d}{\mathrm dx}(\sec x\times\cos x)=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x+\sec x\times\dfrac{\mathrm d}{\mathrm dx}(\cos x)

=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{+\sec x\times(-\sin x)}

=\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x\boxed{-\sec x\times\sin x}

(meaning that a factor of \sin x is overlooked)

Then

\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x-\sec x\times\sin x=0

\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)\times\cos x=\sec x\times\sin x

\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\dfrac{\sec x\times\sin x}{\cos x}

\implies\dfrac{\mathrm d}{\mathrm dx}(\sec x)=\sec x\times\tan x

Consider the continuous random variable X, which has a uniform distribution over the interval from 20 to 28.
PIT_PIT [12445]
a) The specified probability distribution is b) 0.5, representing a 50% chance that X assumes a value between 21 and 25. c) 0.25 denotes a 25% likelihood that X takes on a value of at least 26. A uniform probability distribution encompasses two limits, a and b. The probability of obtaining a value lower than x is calculated accordingly. Also, the likelihood of finding a value between c and d is defined in correlation with the observed uniform distribution ranging from 20 to 28.

Zina [12379]
(2 6/7) divided by (1 2/3) equals x over 1.
Cross-multiply and convert mixed numbers to improper fractions:
(5/3)x = 20/7
Solving for x:
x = (20/7) × (3/5)
x = 60/35, which simplifies to 1 5/7 songs per minute.

M=1/2 (d1+d2) solve for d1
babunello [11817]
To solve for d1, the equation D1= -d2+M is derived by first multiplying d1 and d2 by 1/2, adding -d2/2 to both sides, and then dividing both sides by 2/1.
