Answer:

a(11) = 4^10 = 1048576

Step-by-step explanation:

The first term of this geometric sequence, a(1), is 1, and the common ratio, r, is 4.  Each new term is 4 times the previous term.  Thus,

a(n) = 1*4^(n - 1), and

a(11) = 4^10 = 1048576

miley has d decks of playing cards. write an equation for a function that shows how many c cards miley has all together if each
anastassius [24]
Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52  cards in each deck
- We need how many cards in total

So let us think about it from a mathematical standpoint
1 deck= 52 cards         1 x 52= 52
that means.....
2 deck= 104 cards      2 x 52 = 104
3 deck= 158 cards      3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d

The city wants to build a football field. Each wheelbarrow full of dirt covers an area of. Determine how many wheelbarrows full
lesya692 [45]

Answer: 5x^{2}+45x


Step-by-step explanation:

1. First, you must calculate the area of the football field. It is a rectangle, therefore, multiply the lenght by the width to calculate the area:

Area=lenght*width\\Area=(10x^{2}+90x)5x^{2}\\Area=50x^{4}+450x^{3}

2. Then, divide this area by the area covered by a wheelbarrow full of dirt.

x: number of wheelbarrows full of dirt needed for the field.

x=\frac{50x^{4}+450x^{3}}{10x^{2}}=5x^{2}+45x
