Thanks Rom,   

RainbowPanda, maybe it will help you understand what Rom has  said if I tell you this:

A monomial is an eqpression with only one term.    Like   5x   or   -3y^2   

Product means multiply.

So you are just looking for 2 things that multiply together to make  \( -84a^6b^{10} \)     there are lots and lots of correct answers.

Rom has introduced all those c's and m's.  They are just numbers.  You have to use numbers that work. Rom is not suggesting that you leave them as c's and m's     

Thanks so much!

Good work RainbowPanda   

\(A_2=A_1+2\\ A_3=A_2\cdot(-4)\\ A_4=A_3+2\\ A_5=A_4\cdot(-4)\\ \)

For the next term, you take 120 and add two to get 122. 

Then, you multiply by -4 to get -488. 

Finally, you add two again to get -486. 

The next three terms in order are 122, -488, -486. 

Mmm  sounds like either the question or the answer is wrong.

Certainly 3/8 of a second of arc does equal 0.00010416667 degrees.

   But is that really what was meant?

A stem and leaf diagram has the units digit in a separate column, so we have C. 55 as the answer.

We cannot see a 0 in the 1's row, so A is not correct. We cannot see a 1 in the 2's row, so B is not correct. We do see a 4 in the 4's column, so C. is the answer.

- Daisy

it makes me sad that you can't figure out the first one.

any of these will do

\(c_1 a^{m_1}b^{n_1} \cdot c_2 a^{m_2}b^{n_2} \\ \text{where } \dots \\ c_1 \cdot c_2 = -84 \\ m_1 + m_2 = 6 \\ n_1 + n_2 = 10 \\ \text{use your rainbow panda powers to choose two monomial that satisfy these 3 requirements!}\)

for the second one we know (should know) that the volume of a cube is \(s^3 \text{ where s is the length of a side.}\)

our side length is doubled giving us \(s=4x^5\)

Thus the new volume is \(\left(4x^5\right)^3 = 4^3 \cdot x^{5 \cdot 3} = 64 x^8\)

Use this formula and write it down, so that you can remember it in the future:

[New amount / Old amount] - 1  x  100 =Percentage increase

[324 / 6] - 1  x  100 =

[54] - 1 x 100 =5,300% percentage increase.

Day 3 because the bar is the highest

You can tell by looking at the graph that the answer is C. 1975

i am still confused

wait.. so it's 14...

You have rounded down. 22/162*100 ≈ 13.58... The .58 is bigger than 1/2 so you need to round up to get 14% to the nearest percent.

Ohh um so 13% correct? 

Not quite! You need to divide 22 by 162, not the other way round!

14 + 37 + 22 + 56 + 33 = 162 

162 / 22 = 7.363636363 * 100 = 736.363636 but 736%

Am i right or

Show the steps you took to get 736%.

736% ?

Add up all the numbers to get the total. Divide the number under the Blue label by this total. Multiply the result by 100 to turn it into a percentage.

Since 12 = 2²*3 we can write 12^x*3^3x=18 as 2^2x*3^4x=2¹*3²

Divide both sides by 2¹*3² to get 2^(2x-1)*3^(4x-2)=1 or 2^(2x-1)*3^(4x-2)=1 or

2^(2x-1)*3^2(2x-1)=1 or (2*3²)^(2x-1) = 1 or 18^(2x-1) = 1

Now the only way 18 to some power can equal 1 is if that power is zero. Hence 2x - 1 = 0

so x = 1/2

Solve for x
3^(4 x) 4^x = 18

Factor out the common power x from the left hand side:
324^x = 18

Take the logarithm base 324 of both sides:
 x = 1/2

Max: 1927->60

Min: 1929->46

60-46=14

Exceeds by 14

cos V = TV/24, so TV/24 = 2/3

Can you take it from here?

Thank you SO much!
