An arithmetic sequence word problem
"Daniela received $30 as a birthday present and decided to save the money to buy a new video game console. From the following week onward, she added $12 to her savings each week.Let f(n) be Daniela's savings weeks after her birthday"

Geometric:
Ethan wants to recreate the story of the rice and the chessboard, but he only has a mancala board (which has <span><span>14 </span></span>spaces). If he puts <span><span>1</span></span> grain of rice in the first space of the mancala board, <span><span>2</span></span> on the second, <span><span>4 </span></span>on the third, and so on, doubling the amount for each space, how many total grains of rice will be on the board?

The first attachment is how to solve the money problem and the second attachment is the rice problem

Hey There!

If i got this down right,
An = A1 + (n - 1)d
Sn = A1 + A2 + A3 + ... + An
A1 is given by
Sn = n (A1 + An) / 2
For Example

An = A1 + (n - 1)d
= 6 + 3 (n - 1)
= 3 n + 3
n = 50

Hope This Helps!!!

(2x^3-5x^2+8)(x+3)=?
Alla [95]
(2x³ - 5x² + 8)(x + 3) = ?
First step is to distribute.

2x^4 + 6x³ - 5x³ - 15x² + 8x + 24
Now combine like terms.

2x^4 + x³ - 15x² + 8x + 24

This is your answer, since you can't simplify any further or solve it without some more information.

Drag expressions into order to show a way to find 3 × 56.
lina2011 [118]
As we could "drag" these together, we could then do it the easy way.

  56
+56
+56
-------
168
------------------------

Or we could also do the following:

56*3:

6*3= 18.

Carry the one. 

5*3 = 15+1 (which was carried). = 16

(16+8) = 168

The period 7 (in seconds) of a pendulum is given by T = 2pi√( L divided by 32) where L stands for the length (in feet) of the pe
oksano4ka [1.4K]

Answer:

128 feet

Step-by-step explanation:

t = 2\pi \sqrt{\frac{l}{32} }

So now we will substitute the values of T and π into the equation.

12.56 = 2 \times 3.14 \sqrt{ \frac{l}{32} }

12.56 = 6.28 \sqrt{ \frac{l}{32} }

Divide both sides by 6.28

2 =  \sqrt{ \frac{l}{32} }

Square both sides.

4 =  \frac{l}{32}

Multiply both sides by 32

l = 4 \times 32 \\ l = 128 \: feets
