Erica can run 1/6​ start fraction, 1, divided by, 6, end fraction of a mile in a minute. Her school is \dfrac23 ​3 ​ ​2 ​​ start
EastWind [94]
Her school is 2/3 miles away

2/3=4/6miles

So we need to find out how long it will take for her to run home from school...

School=4/6 miles

In 1 minutes she can run 1/6 miles

1min=1/6miles

In 2 minutes she can run 1/6+1/6 miles (1/6+1/6=2/6)

2min=2/6miles

3min=3/6miles

4min=4/6miles

It will take Erica 4 minutes to run 4/6 miles, so it'll take her 4 minutes to get home.

Inessa [10]

Answer:

- 4

Step-by-step explanation:

Step 1:

- 2 ( 3x - 4 ) - x - 3 = 33

Step 2:

- 6x + 8 - x - 3 = 33

Step 3:

- 7x + 5 = 33

Step 4:

- 7x = 28

Step 5:

- 28 = 7x

Answer:

- 4 = x

Hope This Helps :)

Compute the discriminant D(x,y)D(x,y) of the function. f(x,y)=x3+y4−6x−2y2+3 f(x,y)=x3+y4−6x−2y2+3 (Express numbers in exact for

Answer:

Point                Critical point

Q (2,0)                 local minimum

R (-2,1)                 Saddle

S (2,-1)                  local maximum

T ( -2,-1)                Saddle

O ( -2,0)                Saddle

Step-by-step explanation: INCOMPLETE ANSWER INFORMATION ABOUT THE POINTS ARE RARE

f(x,y) = x³ +y⁴ - 6x -2y² +3

df/dx = f´(x) = 3x² -6x

df/dxdx = f´´(xx) = 6x

df/dy = f´(y) = -4y

df/dydy = 4

df/dydx = df/dxdy = 0

df/dydy = f´´(yy)

D = [ df/dxdx *df/dydy] - [df/dydx]²

D = (6x)*4 - 0

D = 6*2*4     D > 0 and the second derivative on x is  6*2 = 12

so  D > 0 and df/dxdx >0  there is a local minimum in P

Q(2,1)

D = (6*2)*4  D>0  and second derivative on x is 6*2

The same condition there is a minimum in Q

R ( -2,1)

D = 6*(-2)*4 = -48  D< 0 there is a saddle point in R

S (2,-1)

D = 6*2*4 = 48  D > 0 and  df/dxdx = 6*-1  = -6

There is a maximum in S

T ( -2,-1)

D = 6*(-2)*(4) = -48  D<0 there is a saddle point in T

O ( -2,0)

D = 6*(-2)*4 = -48 D<0  there is a saddle point in O

your realized income is 3167.89/month, and your fixed expenses are 954.32/every 2 weeks. if you save 50% of your discretionary m
svetlana [45]

Answer:

<em>each month, you are saving 629.625</em>

<em />

Step-by-step explanation:

Your income is 3,167.89 each month.

Every 2 weeks, your fixed expenses are 954.32.

=> Average fixed expenses for 1 week is: 954.32 / 2= 477.16

As there are 4 weeks in each month, so that your fixed expenses each month are: 477.16 x 4 = 1,908.64

Your discretionary money for each month = Your monthly income - Your monthly fixed expenses = 3,167.89 - 1,908.64 = 1,259.25

=> Your discretionary money for each month is 1,259.25

As you save 50% of discretionary money each month, so that your monthly saving can be calculated as following:

<em>Monthly saving = Monthly discretionary money x 50% </em>

<em>= 1,259.25 x 50 / 100 = 629.625 </em>

<em />

<em>So that each month, you are saving 629.625</em>
