So 810-729=81 so then you get the nine friends and divide 81  and 9 so then it would equal out to 9$ a person 

Log is the same as exponent, so if we have: 10^2=100. We say 2 to the base 10 is the "Log" of 100.

What was the question?

0.04x^2 +1.2x-200=0   multiply through by 100

4x^2 + 120x - 20000 = 0  divide through by 4

x^2 + 30x  - 5000 = 0   using the quadratic formula we have that : x≈ -87.284  and  x ≈ 57.284

That's only YOUR opinion!!.

what do i do with 0.04x^2 +1.2x-200=0?

x = -87.2842  and  x = 57.2842

A group of 9 friends takes a white-water rafting trip. The total price of the trip before any discounts is $810. Each person in the group receives a student discount. The total price with the discount is $729. How much is the discount per person?

The total discount is=

810 - 729=$81, since there are 9 friends in the group, then we have:

$81/9=$9 Discount per student

To find the mean, simply add up all the numbers and divide by the # of values added.

12+12+12+2+19+1.3+10=68.3

68.3/7= about 9.757

WHAT IS THE MEAN OF 12, 12, 12, 2, 19, 1. 3, 10.

Their sum=71/8

The mean=8.875

A pet shop drops the price of a certain aquarium 12% to a sale price of $176. What was the original price?

If the original price was n, then,

n - .12n=176

.88n=176 we divide both sides by .88

n=176/.88

n=200, which was the original price. Because 200 - 12%of 200=176

2x-3)(4x-5)=0

=8x^2 - 22x + 15 = 0

x = 5/4  and  x = 3/2

I assume you are tasked with finding the roots, or zeroes.

Since if either of the binomials equals 0, the entire equation works (e.g. 0 times anything equals zero).

So set both binomials equal to zero, and solve for the two roots.

2x-3=0

2x=3

x=3/2

and

4x-5=0

4x=5

x=5/4

So, the two roots are 5/4 and 3/2.

Four more than seven times a number is six less than five times the number.

7N + 4 + 6 = 5N    simplify

7N + 10  = 5N   

-10 = 2N

N = -5

-6= b/18    multiply both sides by 18

-108 = b

First of all, get the VERTICAL component of the initial velocity:

V = 37m/s (sin(44.9) = 26.117 m/s

When the Vertical velocity equals ZERO, the projectile has reached its highest point (apex)

since v= vo + at     (vo = origianl velocity     a = acceleration of gravity = -9.80 m /sec^2   t = time)

ZERO=  26.117 + (-9.80 t)

Solving for t

-26.117 = -9.8 t

26.117/9.8 = t = 2.665 seconds

NOW,  use the position equation  pf = po + vt +1/2at^2   pf=Final position (max height...apex)

po = 0

so:

pf = 26.117 (2.665) + 1/2 (-9.8)(2.665)^2   =  69.60 + (-34.8) = 34.8 m  max height

"a quantity representing the power to which a fixed number (the base) must be raised to produce a given number."

The vertical displacement is given by:

h = v(sin theta)t + 1/2 (-9.8) t^2

And  h'  is the vertical velocity at any time.......this is 0 at the max ht.

And h'  =   vsin(theta) - 9/8t  =  37sin(44.9)  - 9.8t   ...... set to 0

37*sin(44.9) = 9.8t

37*sin(44.9)/ 9.8 = t =  2.665 s

And putting this back into the position function, the max ht. =

h(2.665) =  about 34.8 m

Here's the graph :  https://www.desmos.com/calculator/smv5klqan8

=  54  - (3x65)/4  + (32 x 5)  =  214 - 195/4  =  214 - 48 3/4  =  165 1/4

So substitute  ' -2 ' for 'y'

3x - 4 (-2) = 5/3

3x + 8 = 5/3

3x = -8 + 5/3 =  -24/3 + 5/3 = -19/3

x = -19/3    (1/3)  =   -19/9  =  - 2 1/9

p=12 when q=8 p=? when q=6

12:8 is proportional to p:6

since 12/8=1.5, therefore 1.5 X 6=9 so, we have:

p=12:q=8 is proportional to:

p=9:q=6

Well 10^2 = 100   and 11^2 = 121    sooooooo I would say the approximate NEAREST INTEGER answer is  '10'
