Because this is an infinite sequence, we can use the following formula:

a1/r

a1 is the first number in the sequence, r is the rate of change.

To find r, we do the second value divided by the first. So

1/2 / 1 = 1/2
r = 1/2

Now we plug in to our equation.

1 / 1/2

= 2

So your sum is 2

I hope this Helps!

RUDIKE [14]
We are given with two dimensions of a can of paint in which I assume is a  cylinder: 14 cm diameter and 16 cm height. In this case, the formula to be used is V = pi*d^2*h/4. substituting the given data above, V = pi*14^2*h/16 equal to 2462 cm^3. units must be consistent throughout to achieve the right answer.

Suppose the function F(c) represents the earnings of a volleyball team from selling c cupcakes. They are selling each cupcake fo
navik [9.2K]

Answer:

The variable c represents the domain as it is the independent variable.

The domain of the function F(c) is given by c ≥ 0.

So, only positive values for the input make sense.

The upper limit of the domain is +∞ and lower limit is 0.

It is not possible for the team to earn $50.50 as it will be only multiple of 2.

Step-by-step explanation:

If F(c) represents the earning of a volleyball team from selling c cupcakes and each cupcake costs $2 each, then the equation that models the situation is  

F(c) = 2c ..... (1)

The variable c represents the domain as it is the independent variable. (Answer)

The domain of the function F(c) is given by c ≥ 0. (Answer)

So, only positive values for the input make sense. (Answer)

The upper limit of the domain is +∞ and the lower limit is 0. (Answer)

51=3k i do not get this can you help me please
lorasvet [3.4K]

51 = 3k. We can switch this around to 3k = 51 (because it's easier for me)

3k = 51.

We divide by 3 on both sides to just get "k".

3k / 3 = 51 / 3

k = 17.
