Min read so far :

26 + 39 + 38  = 103

Min left to read =

180 - 103  =  77

Just measure it using a ruler place it on the cone upward.0 inch goes on the bottem

I think .5:6

The  nth term of the sequence is given by : 3*2^(k-1)

a₁  = 3    a₂  = 6     a₄  = 24

So......

3*2^(k-1) >  80

2^(k-1) >  80/3

k - 1  >    log ( 80 / 3)  / log (2)

k  >     log ( 80 / 3)  / log (2) + 1

k > 5.737

So  k  = 6  ...and 3*2(6 - 1)   = 96

2cos^2 x+4sinx cosx =?

It is a linear relationship because it has a y-intercept and a constant slope. The equation is:

y=99.00+29.95x

You could also change x into m, meaning months.

The independent variable is months, and the dependent is cost.

1. Find the mean (average)

[79+ 82 + 84 + 81 + 77+ 85+ 82+ 80+ 78+ 83 ]  / 10    =   81.1

2. Find the difference between each data value and the mean and take the absolute value of each difference

abs [79 - 81.1] = 2.1

abs [82 - 81.1] = .9

abs [84 - 81.1] = 2.9

abs [81 - 81.1] = .1

abs [77 - 81.1] =  4.1

abs [82 - 81.1] = .9

abs [85 - 81.1] = 3.9

abs [80 - 81.1] = 1.1

abs [78 - 81.1] = 3.1

abs [83 - 81.1] = 1.9

4. Find the mean (average) of these differences

[ 2.1 + .9 + 2.9 + .1 + 4.1 + .9 + 3.9 + 1.1 + 3.1 + 1.9 ] / 10  =  2.1  = MAD

ln or log 10

when you add up 1000+1000+1000+1020, you get 4020. then add 20,20,30,and 10, which gets you 4100. When you add the smaller numbers you get 100, but since you've been working with thousands in the original question posted above, your mind automatically rewrites it in your head as 5000.

y * x / e = yxe

F.  II Only

^ Wild guess XD

Distribute A to (B+C) and it = AB+AC

AB+AC= AB+AC

y times x all over e

 |-2|= 2 4x2= 8

thx u very much

4y-(-2y-3)=9      simplify

4y + 2y + 3 = 9

6y + 3  = 9      subtract 3 from both sides

6y  = 6        divide both sides by  6

y  = 1

9 +10 =19. you have to add 9 and 10 to get the answer.

Same i got 4,100 in my head you calulated that wrong.

Solve for x:
x/8 = 342 x^2

Subtract 342 x^2 from both sides:
x/8 - 342 x^2 = 0

Factor x and constant terms from the left hand side:
-1/8 x (2736 x - 1) = 0

Multiply both sides by -8:
x (2736 x - 1) = 0

Split into two equations:
x = 0 or 2736 x - 1 = 0

Add 1 to both sides:
x = 0 or 2736 x = 1

Divide both sides by 2736:
Answer: |x = 0         or        x = 1/2736

2pi/(pi/2)

2pi/(pi/2)=2pi*2/pi= 2pi/1*2/pi = 4pi/pi = 4

However, if it is 2*pi/pi/2 then it is 1. It depends on where the parenthesis are.

In my head it is 4100. When I calculate it is 4100. What is the problem?

you just put in x/y using the slash

286.28/26 = 11.0107692307692308

≈$11.01

That depends, put what in a fraction? Decimals, converting other fractions, ect. Please give more details.
