Mathematics

scoray [572]3 years ago
5 0

Answer:

a₁ = - 256 , r = - \frac{1}{4}

Step-by-step explanation:

The nth term of a geometric sequence is

a_{n} = a₁ (r)^{n-1}

Given

a_{n} = - 256 (-\frac{1}{4}) ^{n-1} , then by comparison

a₁ = - 256 and r = - \frac{1}{4}

What’s 4⁄5 ÷ 3⁄5 equals
stepladder [879]

Answer: 7/5

This is how we add

4/5+3/5

Step 1

Since our denominators match, we can add the numerators.

4 + 3 = 7

That gives us an answer of

7/5

Step 2

Can this fraction be reduced?

First, we attempt to divide it by 2...

No good. So next you try the next prime number, which is 3...

No good. So next you try the next prime number, which is 5...

No good. So next you try the next prime number, which is 7...

No good. 7 is larger than 5. So we're done reducing.

And we're done! Here's the final answer to 4/5 + 3/5

4/5 divided by 3/5 equals 7/5

Which expressions are equivalent to 3(4h + 2k)?
faltersainse [42]

Answer:

A

Step-by-step explanation:

If we distribute the 3 to the equation in the parenthesis, we end up with this

12h + 6k

Now, let's do the same thing for the other two equations

3(2k + 4h) = 6k + 12h

You can rearrange this equation to look like 12h+ 6k, making it the exact same as 3(4h + 2k).

So A is equivalent

How about B?

3(4h + 2h) = 12h + 6h = 18h

18h does not equal 12h + 6k, so B is not equivalent
