Is 1.38339E-05 a negative number?

No, it is not a negative number. It just means it is very small fraction=.0000138339

Use the calculator on the home page you lazy person.

If by you mean "exponential form" you mean "scientific notation," we have

4.728  x 10⁰

It can't be split evenly over 9 days, because $5.33  isn't evenly divisible by 9....

lim(f(x)+(x^2+x)/(x^2+1)),x->infinity 

lim_(x->infinity) (f(x)+(x^2+x)/(x^2+1))

lim(x-ln(2+e^(x+3))),x->infinity 

lim_(x->infinity) (x-log(2+e^(x+3))) = -3

 lim(ln(1+e^x)-sqrt(x)),x-> -(infinity

lim_(x->-infinity) (log(1+e^x)-sqrt(x)) = (-i) infinity

lim((a^(x+1)+e^x)/(a^x+e^(x+1)),x->infinity,a>0

=1/e assuming abs(a)<1

Here's a mathematical proof that demonstrates why this can't happen:

Suppose that we have the data set :

A1, A2,.....An   where An is the largest value 

And suppose that B is a mean that is greater than An......and suppose that we assume that

[ A1 + A2 +.....+An] / n =  B     is true  ........    multiply both sides by n

A1 + A2 +.....+ An   = Bn    .... implies that

A1 + A2 +.......+ An = B + B + B........   summmed "n" times

But B >  than any term on the left.....and since we have the same number of terms on each side, the right side must be larger than the left side.....thus, they cannot be equal....and our assumption is false......so, the mean cannot be greater than any individual value in a set of data

2(x+4)=-5x+1   distribute the 2 on the left over the terms in the parentheses

2x + 8 = -5x + 1     subtract 8 from both sides, add 5x to both sides

7x  = - 7       divide both sides by 7

x = -1

If the scale is 1:80, then 350/80=4 3/8 inches on the map.

Solve for x:
2 (x+4) = 1-5 x

Subtract 1-5 x from both sides of 2 (x+4) = 1-5 x:
2 (x+4)-1-5 x = (1-5 x)-1-5 x

(1-5 x)-(1-5 x) = 0:
2 (x+4)-(1-5 x) = 0

2 (x+4) = 2 x+2 4:
2 x+2 4-(1-5 x) = 0

2×4  =  8:
-(1-5 x)+2 x+8 = 0

-(1-5 x) = -(-5 x)-1:
-(-5 x)-1+2 x+8 = 0

-(-5)  =  5:
5 x+2 x-1+8 = 0

Grouping like terms, 5 x+2 x-1+8 = (2 x+5 x)+(8-1):
(2 x+5 x)+(8-1) = 0

2 x+5 x = 7 x:
7 x+(8-1) = 0

8-1 = 7:
Answer: | 
| 7x+7 = 0

-7 - (-7)=-7 + 7=0

80=8 X 10^1

i^{4n+ 1} = i

i^{4n + 2} = -1

i^{4n + 3} = -i

i^{4n + 4} = 1

Where i is an integer > 0

i¹⁹ can be written as i^{4(4) + 3}, so it equals  -i

Another way to figure this is to to divide the power on i by 4.

If the remainder = 1, then the answer is i

If the remainder = 2, then the answer is -1

If the remainder = 3, then the answer is -i

If the remainder = 0, then the answer is 1

the answers are x= 8.0, y=11, A=45 degrees but I didn't know how to get those answers using SohCahToa and Pythagorean Theory

U know ur a b***h yourself!!!👴🏿

Thankyou. I mixed up mixed up mutiplication with addition. It has been a while scince i needed to do this.

x = -b±√b²-4ac / 2a

A quick google search can tell you the quadratic formula.

Thank you Heureka,

I will study your answer :)

Since Jamie bought exactly 3 more hot dogs than Amy at $4.50 more, the price of one hot dog must be $4.50/3 = $1.50. The cost of the soft drinks is irreleveant because the same amount was purchased by both people.

NoMathkid,

0^0      makes no sense it is undefined.       

It is not possible to get a mean begger than your data!

Mean is a measure of central tendancy!   It is the same as average.

The sum of your set is=7.69

The mean then is        =7.69/3=2.563..........etc.
