Three consecutive even integers have a sum of -48. Find the largest integer.
kobusy [5.1K]

Answer:

<h3>           - 14</h3>

Step-by-step explanation:

{x -  some integer}

2x  -  the first even integer

2x+2  -  the second consecutive even integer

2x+4  -  the third consecutive even integer (the largest)

2x + 2x+2 + 2x+4  - the sum of three consecutive even integers

2x + 2x+2 + 2x+4 = -48

   6x + 6  = -48

        ÷3         ÷3

    2x + 2 = -16

         +2      +2

     2x+4 = -14

If the half-life of a radioactive substance is 2,800 years, then at what rate is it decaying?
vlada-n [284]

Answer:

0.0001075

Step-by-step explanation:

The relation between halflife and rate at which it is decaying is given by

t_{\frac{1}{2} } =\dfrac{log2}{rate}

now in the above problem halflife is given as 2800 years substituting in the above equation we get the value of rate at which it is decaying to be rate=0.0001075.

Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.
Inessa05 [86]
Hey there.

When writing a polynomial in standard form, you always want to start from the highest degree (exponent), so let's simplify our expression before doing so.

-2x^{3} + 6x^{3} = 4x^{3};
This number will go first as it has the highest degree.
Up next will be '-3x', as it has a degree of 1.
After this, we have 6, having a degree of 0.

Let's set up our new polynomial with this information;
4x^{3} - 3x + 6.

This is known as a cubic trinomial since it has three terms and has a degree of 3.

Your correct answer is "D.)"

I hope this helps!
