11. Find the sum of the arithmetic series. overset [22] underset{k=1}\huge{Sigma) (-4k - 13) =

sergiy2304 [10]

Answer:

okay, we need to add up for all k=1 till k=22

we could do it like this

(-4*1 -13) + (-4*2 -13) + (-4*3 -13) + ...

but this is long and boring, so we need another valid, yet vastly faster method to calculate this sum

we know that the "-13" part will occur 22 times, so let's write this component as "-13*22"

the -4k gents bigger with each step, k will take all the natural numbers from 1 to 22

so we could write

"-4 * (1+2+3+4+5+6+7...+21+22l

alot simpler and faster, but not fast enough

let's add up all numbers from 1 to 22 into one number

1 + 22 = 23

2 + 21 = 23

3 + 20 = 23

...

this works eleven times (bc we use up 2 numbers in each step), so the numbers from 1 to 22 added up are just

23*11= 230+23 = 252

now let's construct the final calculation

-4 * 252 -13*22 = -1294

there's your sum.

hope it helps you overall.

brainliest would be very kind ic some else leaves an answer, may it be just a greeting

Answer:

A) 30 cubes.

B) 30 units³.

Step-by-step explanation:

A) 1. Calculate the volume of the rectangular prism, as following:

$Vr=(lenght)(width)(height)$

2. You have that:

- The length is: $1^{\frac{1}{2}}ft=1.5ft$

- The width is: $1ft$

- The heigth is: $2^{\frac{1}{2}}ft=2.5ft$

3. Substitute these values into the formula:

$Vr=(1.5ft)(1ft)(2.5ft)=3.75ft^{3}$

4. The volume of one cube is:

$Vc=side^{3}$

5. The length of one side is: $\frac{1}{2}ft=0.5ft$

6. Substitute this value into the formula:

$Vc=(0.5ft)^{3}=0.125ft^{3}$

7. The number of small cubes that can be packed in the rectangular prism is:

$cubes=\frac{Vr}{Vc}\\cubes=\frac{3.75ft^{3}}{0.125ft^{3}}\\cubes=30$

B) 1. The length, the width and the height of the rectangular prism in term of units cubes is:

$Length=\frac{1.5ft}{0.5ft}=3units$

$Width=\frac{1ft}{0.5ft}=2units$

$Heigth=\frac{2.5ft}{0.5ft}=5units$

2. Therefore, the volume of the rectagular prism in terms of the small cube and a unit cube is:

$Vr=(3units)(2units)(5units)=30units^{3}$
