Answer:

The required equation is a_n=a_1+(n-1)d

Step-by-step explanation:

To find : Which of the following are explicit equations for the nth term of some kind of arithmetic sequence?    

Solution :

The Explicit formula which shows the nth term of a sequence in terms of n is given by,

a_n=a_1+(n-1)d

Where, a_n is the nth term

a_1 is the first term

n is the number of terms

d is the common difference

Therefore, The required equation is a_n=a_1+(n-1)d

If 800g of a radioactive substance are present initially and 8 years later only 450g remain, how much of the substance will be p
artcher [175]

A=Pe^(rt)

P = 800g

t = 8 years

A = 450g

r = This is what we will try and find to start with

450=800e^(r*8)

After running the math through a calculator, we end with r = -0.07192

Now we just re-input this information into our equation: A=800e^(-0.07192*16)

A=800e^(1.15072)

Now we will re-write the equation using the negative exponent rule:

A = 800 1/e^1.15072

Combine right side:

A = 800/e^1.15072

Then do the math:

A = 253.12709836......

That will give us A = 253 (rounded to the whole number)

I hope this helps! :)

-4/9x=16/27 alguien que me ayude
Andre45 [30]
<h3>Answer</h3>

First multiply everything by 27

-  \frac{4}{9} x =  \frac{16}{27}  =  \\ 27 \times ( -  \frac{4 }{9}x) = 27 \times  \frac{16}{27}

Then approximate the terms with 27 if it's possible (27 and 9) (27 and 27)

3 \times (   - \frac{4}{1} ) = 16

So now multiply again

3 \times ( - 4) =  - 12

And you have

- 12x = 16

x =  -  \frac{16}{12}  =  -  \frac{4}{3}

You're welcome if it's right

A 15-foot log is split into 2 pieces. How long are the pieces if the longest piece is 1.5ft shorter than two of the shorter piec
Allisa [31]

Answer:

8.25 ft & 6.75 ft

Step-by-step explanation:

So we know it's split into two pieces, right? So normally that would be 7.5 ft each. But one is 1.5 ft longer than the other. So as a result, I divided that by 2 to add 0.75 ft to piece one and subtract 0.75 ft from piece two's length. So, the longer piece is 8.25 ft, and the shorter one is 6.75 ft.
