on rhe calculator when finding R = 19,99.5/ (A*squareroot of 5* .072)

R=1,999.5/ (A*(sqrt(5)*.072), If you want a numerical value for "A", then your equation is wrong. If you want "A", then have to know "R" and vice versa.

115 s= how many min

115/60=1 minute and 55 seconds.

A reflex angle is an angle of more than . A full angle is therefore a reflex angle, while acute, obtuse, right, and straight angles are not.

10,000(1+1.12)= I think this is what you meant: 10,000(1 + .12)=11,200

OMG! I found the equation of parabola :(((

i think:

let s found what does your y s equal to:

5x-6y-16=0                               13x-10y-48=0                   

6y=5x-16                                  10y=13x-48

y=5x/6-16/6                               y=13x/10-48/10

lets found the point intersection of theese points:

5x/6-16/6=13x/10-48/10

x = 32/7

put x into one of the equations to find y 

y=(5x32/7)/6-16/6

y=8/7

so your parabola will be tangen to the point (32/7,8/7)

your equation will be:  y=(x-32/7(to shift it 32/7 right through x-axes))^2+8/7(to shift it 8/7 through y-axes) 

\(y=\left(x-\frac{32}{7}\right)^2+\frac{8}{7}\)

and not to pass through any other lines one of your equations will be:

\(y=1000\left(x-\frac{32}{7}\right)^2+\frac{8}{7}\)

OR

\(y=-1000\left(x-\frac{32}{7}\right)^2+\frac{8}{7}\)

here is your graph:

Hiya!!! I'm uber bored...

Sequence:     n ---> 2n + 20.

To find the value of the fifth term,  n = 5

                     5 --->  2(5) + 20     --->     10 + 20     --->     30

x - 7y  =  2          and         x²  =  34y² + 7xy  - 16

Take the linear equation (x - 7y  =  2) and solve it for either  x  or  y.

It seems easier to solve it for x:  x  =  7y + 2

Replace this into the other equation:

  x²  =  34y² + 7xy  - 16     --->       (7y + 2)²  =  34y² + 7(7y + 2)y  - 16

Simplify:     --->     49y² + 28y + 4  =  34y² + 49y² + 14y - 16

Simplify:     --->     0  =  34y² - 14y - 20

Divide both sides by 2:     0  =  17y² - 7y - 10

Factor:                             0  =  (17y + 10)(y - 1)

Solve:                                       y  =  -10/17     or     y  =  1

Substituting these values back into the equation:  x - 7y  =  2

     x - 7(-10/17)  =  2     --->     x  =  -36/17      --->     Answer:   (-36/17, -10/17)

     x - 7(1)  =  2             --->     x  =  9              --->     Answer:    (9, 1)

I believe that when graphed   x²  =  34y² + 7xy  - 16  is a hyperbola  and  x - 7y  =  2  is a straight line, so that their solution, their intersection, will either by no points, one point, or two points; in this case:  two points.

Perhaps someone can post the graph ...

Ohhhhhhhhh, lol!

Wow thanks a lot!!   

How many cats are there where?

If y = 60, then f(x) = 60.

Since f(x)  =  2x² - 2x - 24,  60  =  2x²​ - 2x - 24

Subtracting 60 from both sides:  0  =  2x²​ - 2x - 84

Dividing both sides by 2:             0  =  x² - x - 42

Factoring:                                   0  =  (x - 7)(x + 6)

Soving for x:                               x = 7  or  x = -6

i think:

parallel mean the slope s are the same  

so your equation: y=mx+b where m is the slope will be y=7/6x+b

let s put (12,-5) instead of (x,y):

-5=7/6*12+b our b will be -19

so our equation will be:

y=7/6x-19

Tan?

it's just nonsence  you said to post nonsence it wasn't suposed to make sence 

He knew that...

I don't get it...

1,970.67 is 16% of what number

Let the number be x, the we have:

.16x=1970.67 divide both sides by .16

x=1970.67/.16

x=12,316.6875

The way to calculate this is to work backwards, knowing that we can calculate the percentage of a number by multiplying it by the percentage and dividing by 100.

\(1970.67=x*16/100\)

By rearranging, we can find x as shown.

\(x=1970.67/0.16\)

\(x=12316.69\)

Therefore, 1,970.67 is 16% of 12,316.69.
