Answer:

Domain: (−∞,∞),{x|x∈R}

Step-by-step explanation:

the domain will be Domain: (−∞,∞),{x|x∈R} because

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

A fair number cube ,labeled with 1 through 6 is rolled four times .What is the probability of rolling a 6 all four times ?

OLga [1]

Answer:

1/1296

Step-by-step explanation:

Assuming that the probability of rolling a number is the same (1/6), all we have to do it multiply 1/6 by 4 (the number of times you roll the dice).

So 1/6 * 1/6 * 1/6 * 1/6 is just 1/6^4 and 6^4 is 1296.

Therefore the probability of rolling a 6 4 times in a row is 1/1296.

Jamie was asked to make r the subject of the formula

aksik [14]

Answer:

Assuming the formula below, the answer is:

$r=\dfrac{12s}{12+t}$

Explanation:

I can teach you how to make r the subject of a formula, with an example.

Other similar question asks to make r the subject of this formula:

$t=\dfrac{12(s-r)}{r}$

1. Apply multiplication property of the equalities: muliply both sides of the equality by r

$t\times r=12(s-r)$

2. Apply distributive property on the right side

$t\cdot r=12s-12r$

3. Addition property: ad 12r to both sides

$t\cdot r+12r=12s$

4. Common factor r on the left side

$r(12+t)=12s$

5. Division property of equalities: divide both sides by 12 + t

$r=\dfrac{12s}{12+t}$

Need help with this one it kind of hard

sdas [7]

The answer is D because the question is basically asking you to solve for the equation at t = 5. We get:
$v(5) = 45+4(5) = 65$

Since it models speed of the car, and not the time, the answer is D.
