Answer:

$9

Step-by-step explanation:

ok so this is what she owes- **i'm 'separating' them to make it easier**

$4 and $12 so let's add those together-

4+12=$16 so she owes 16 dollars in fines and late fees

and let's remember that she paid $7 for her late fee and assuming that she gets her $3 back she has $3 so far then for the 12 dollar fine she pays 20 dollars, and we're assuming that she gets back $6

she should have $9 left

good luck :)

**please let me know if this was incorrect/ not what you were looking for or both**

have a nice day!

Susie is paying $538.66 every month for her $150,000 mortgage. If this is a 30 year mortgage, how much interest will she pay ove
zhuklara [117]

Answer:

Step-by-step explanation:

So First we know she pays (538.66) every month (12months in a year ) for (30) years

So 538.66*12*30 = 193,917.60

Then, we take his total payment minus the what he originally owed.

   

193,917.60 - 150,000 = $43,917.60

Compute the Taylor expansion of order n=2 of the function sin(xy) at x=0 and y=0
artcher [175]

Answer:

f(x, y) = Sin(x*y)

We want the second order taylor expansion around x = 0, y = 0.

This will be:

f(x,y) = f(0,0) + \frac{df(0,0)}{dx} x + \frac{df(0,0)}{dy} y + \frac{1}{2} \frac{d^2f(0,0)}{dx^2} x^2 +\frac{1}{2} \frac{d^2f(0,0)}{dy^2}y^2  + \frac{d^2f(0,0)}{dydx} x*y

So let's find all the terms:

Remember that:

\frac{dsin(ax)}{dx}  = a*cos(ax)

\frac{dcos(ax)}{dx} = -a*cos(ax)

f(0,0) = sin(0*0) = 1.

\frac{df(0,0)}{dx}*x = y*cos(0*0)*x = x*y

\frac{df(0,0)}{dy} *y = x*cos(00)*y = x*y

\frac{1}{2} \frac{d^2f(0,0)}{dx^2}*x^2 =  -\frac{1}{2}  *y^2*sin(0*0)*x^2 = 0

\frac{1}{2} \frac{d^2f(0,0)}{dy^2}*y^2 =  -\frac{1}{2}  *x^2*sin(0*0)*y^2 = 0

\frac{d^2f(0,0)}{dxdy} x*y = (cos(0*0) -x*y*sin(0*0))*x*y = x*y

Then we have that the taylor expansion of second order around x = 0 and y = 0 is:

sin(x,y) = x*y + x*y + x*y = 3*x*y

Find the Missing numbers:<br> 250/20=25/?
Liono4ka [1.6K]
I believe it’s 2.
250/20 divided by 10 is 25/2, so 2 would be the missing number.

HELP ME PLEASE
-Dominant- [34]

The total number of cars both the student and the teacher made is 49

let

total cars = x

cars made by student = s

cars made by teacher = t

Total = student + teacher

x = s + t

s = 2/7x

So,

x = 2/7x + t

x - 2/7x = t

t = (7x - 2x) / 7

t = 5/7x

Similarly,

s = t - 21

s = 5/7x - 21

equate both s equation

2/7x = 5/7x - 21

2/7x - 5/7x = -21

(2x - 5x) / 7 = -21

- 3/7x = -21

x = -21 ÷ -3/7

= -21 × - 7/3

= (-21 × -7) / 3

= 147/3

x = 49

Therefore, the total number of cars both the student and the teacher made is 49
