I have a pretty simple question

1 answer:

8 0

A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number. I dont know about the other question

I will give brainliest to anyone who gives me a correct answer

Pachacha [2.7K]

Answer:

Step-by-step explanation:

Let's check the first condition [y=110, t=0] for all the choices and eliminate:

$y = 110e^{7t} - 80\\y = 110e^{0} - 80\\y=30$

$y = 110 - 80e^{-5t}\\y = 110 - 80e^{0}\\y=30$

$y = 30 + 80e^{-2t}\\y = 30 + 80e^{0}\\y=110$

YES

$y = 110 - 80e^{2t}\\y = 110 - 80e^{0}\\y=30$

$y = 30 - 80e^{-4t}\\y = 30 - 80e^{0}\\y=-50$

Note: e^0 = 1

Only C is satisfied. But let's make sure the 2nd condition applies as well.

$y = 30 + 80e^{-2t}\\y = 30 + 80e^{-\infty}\\y=30+\frac{80}{e^{\infty}}\\y>>30$

Hence, y approaches 30 as t goes to infinity. 2nd condition is satisfied as well.

Answer is C

find the probability of rolling a sum of a three first and then a sum of nine when a pair of dice is rolled twice

AleksandrR [38]

Answer:

Step-by-step explanation:

favorable events for a sum of 3 are 12,21

P(sum 3)=2/36=1/18

favorable events for a sum of 9 are 36,63,45,54

P(sum of 9)=9/36=1/4
