What's negative multiples of 3 in set builder-notation

BlackZzzverrR [31]

<span>Multiples of 3 are {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, …….} , these are all the multiples of 3.
Now, we are looking a negative multiple of 3, which means, we need to a negative value of 3 multiples.
=> -3 {-3, -6, -9, -12, -15, -18, -21, -24, -27, -30,…..} These are all the negative multiple of 3 in set builder notation.
Notice, that the numbers are of divisible by 3. Any number that Is divisible by 3 is called multiple of 3.

A circular oil slick is expanding at a rate of 3m/min. How fast is the area of the oil slick changing when the diameter is 48 me

olga55 [171]

Answer:

$48\pi \:m/min$

Step-by-step explanation:

Diameter = 48 m

Therefore radius r = 48/2 = 24 m

$Area \: of \: circular \: oil \: slick \\ A = \pi {r}^{2} \\ differentiating \: w \: r \: to \: t \: on \: \\ both \: sides \\ \\ \frac{dA}{dt} = \frac{d}{dt} (\pi {r}^{2} )\\ \\ \frac{dA}{dt} =\pi \frac{d}{dt} {r}^{2} \\ \\ \frac{dA}{dt} =\pi \times 2{r}\\ \\ \frac{dA}{dt} =2\pi {r} \\ \\ \bigg(\frac{dA}{dt} \bigg)_{r=24} =2\pi \times {24} \\ \\ \bigg(\frac{dA}{dt} \bigg)_{r=24} =48\pi \: m \: per \: min$

Can anyone help I am doing really mad in math

Vadim26 [7]

For this problem, we are going to have to use our order of operations, which is: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction (often abbreviated PEMDAS).

First, let's see if there are any parentheses. There is one set of parentheses which we will have to remove. To do this, we will simply multiply the -4 by the 6, given us a value of -24 to take the place of the -4(6). Now our problem is:

$\dfrac{12^2 - 24 + 1}{11^2}$

Next, we will check for exponents. There are exponents, so we will need to take care of those. $12^2$ is equal to 144, and $11^2$ is equal to 121. We can now substitute these values into the original expression to get:

$\dfrac{144 - 24 + 1}{121}$

Now, we will check for any multiplication or division. Besides the entire expression (which is a fraction), there is none, so we will move on to the next step: Addition and Subtraction. You can see there is addition and subtraction in the numerator. $144 - 24$ is equal to 120, and $120 + 1$ is equal to 121. Our problem is now:

$\dfrac{121}{121} = \boxed{1}$

Our answer is 1.
