kodGreya [7K]

Answer:

6 {a}^{4}  + 5b

Step-by-step explanation:

2a \times  a\times a \times 3 a+ b + 4b \\ 2a \times a = 2 {a}^{2}  \\ 2 {a}^{2}  \times a = 2 {a}^{3}  \\ 2 {a}^{3}  \times 3a = 6 {a}^{4}  \\b +  4b = 5b

Therefore the answer is

6 {a}^{4}  + 5b

Find the distance between the points given. (-3, 2) and (9, -3) A √37 B √61 C 13​
Kitty [74]

Answer:

\huge{ \fbox{ \sf{13 \: units}}}

Option C is correct.

Step-by-step explanation:

\star{ \sf{ \: Let \: the \: points \: be \: a \: and \: b}}

\star{ \sf{ \: let \: A(-3, 2) \: be \: (x1 \:, y1) \:  and  \: B(9, -3) \: be \: (x2 \:, y2) }}

\underline{ \sf{Finding \: the \: distance \: between \: the \: given \: points}} :

\boxed{ \sf{Distance =  \sqrt{ {(x2 - x1)}^{2}  +  {(y2 - y1)}^{2} } }}

\mapsto{ \sf{  \sqrt{ {(9 - ( - 3))}^{2} +  {( - 3 - 2)}^{2}  } }}

\mapsto{ \sf{ \sqrt{ {(9 + 3)}^{2}  +  {( - 3 - 2)}^{2} }}}

\mapsto{ \sf{ \sqrt{ {(12)}^{2}  +  {( - 5)}^{2} } }}

\mapsto{ \sf{ \sqrt{144 + 25}}}

\mapsto{ \sf{ \sqrt{169} }}

\mapsto{ \sf{ \sqrt{ {(13)}^{2} } }}

\mapsto{ \sf{ 13 \: units}}

Hope I helped!

Best regards! :D

an electronics store had 182 video games. if they put them on shelves with 24 on each shelf, about how many shelves would they n
GalinKa [24]
182 games 24 on each shelf basicaaly x shelves is more than or equal to 182 games 1 shelf=24 x times 24>182 divide both sides by 24 x>7 and 4/24 x has to be a whole number since you can't have fractional shelves you have to have more shelves since less shelves won't allow you to carry all of them round up 7 and something rounded u is 8

 8 shelves (if you are a weird store that has fractional shelves then the answer is 7 and 1/6 shelves)

Help answering this simple Series Question? I don't know what I did wrong!
Tatiana [17]
Looks like you just evaluated the summand for the given value of n, whereas the question is asking you to find the value of the sum for the first n terms.

Let S_k=\displaystyle\sum_{n=1}^k\frac3{(-2)^n}. Then S_k is the kth partial sum.

S_1 happens to be the first term in the series, which is why that box is marked correct:

S_1=\displaystyle\sum_{n=1}^1\frac3{(-2)^n}=\frac3{(-2)^1}=-1.5

But the next partial sum is not correct:

S_2=\displaystyle\sum_{n=1}^2\frac3{(-2)^n}=\frac3{(-2)^1}+\frac3{(-2)^2}=-0.75

and this is not the same notion as the second term (which indeed is 0.75) in the series.
