A pair of events are observed to have coordinates (0s,0m) and (50.0s,9.00×109m) in a frame s. what is the proper time interval δ
Ludmilka [50]
To find out time interval δt we need to substract initial time from the final time. In this question first number in the coordinates representes time:

δt=50 - 0
δt= 50s

TIme interval is 50s.

Consider the exponential function
evablogger [386]

<u>Given</u>:

The given function f(x)=19,000 \cdot 0.96 ^x which models the value of Mark’s car, where x represents the number of years since he purchased the car.

We need to determine the approximate value of Mark's car after 7 years.

<u>Value of the car:</u>

The value of the car after 7 years can be determined by substituting x = 7 in the function f(x)=19,000 \cdot 0.96 ^x, we get;

f(7)=19,000 \cdot 0.96 ^7

f(7)=19,000 \cdot 0.7514474781

f(7)=14277.502

Rounding off to the nearest dollar, we get;

f(7)=14278

Thus, the approximate value of Mark's car after 7 years is $14278.

Hence, Option a is the correct answer.

1) A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it i
Feliz [49]

Answer:

1) The puppy takes 10 minutes, the kitty takes 15 minutes.

2) The mama bear takes 9 minutes, the cub takes 18 minutes

3) The sidekick goes at 600 mph, the hero goes at 500 mph.

4) 10 Minutes

5) RSM is so hard, amiright?

Step-by-step explanation:

1) You can simplify the word problem into the equation 1/x + 1/x+5 = 1/6.    For problems like these, you have to simplify the last part to a fraction, not a whole number.   Then you just solve.

2) Same thing.  1/x + 1/x+9 = 1/6.   Solve.  Boom.  Done.

3) A bit different, but it simplifies to 1800/x-100 - 1800/x = .6.   Solve.   C'mon, you should've been able to do this one.

4) Harder, simplifies to 75/x+225/x+15+2.5 = 300/x.   You get the last part because the time the bear took is equal to the time it would normally take, which is the entire distance over the normal pace.   Then you solve and there we go, most of your RSM homework is done.
