Heather is saving for retirement and has been doing a lot of research on how much she should put aside each month. The newest ar

tino4ka555 [31]

If Heather puts in 1.36% of her salary into a retirement account and she makes $63,000 in a year, this can be solved by 1.36% x 63000. First convert 1.36% into a decimal. To do this, divide by 100.

1.36/100=0.0136

1.36% x 63000
=0.0136 x 63000
=856.8
Heather would put $856.8 in for the whole year. To find how much per month, divide by 12.

856.8/12=71.4
Rounded to the nearest dollar is $71.

Heather would put $71 into a retirement account each month.

Note: This was solved by multiply the percent and then dividing by 12 months. You could also do this by dividing by 12 months first and then multiplying the percent.

7 = -x+3. Consider the line y = Find the equation of the line that is parallel to this line and passes through the point (-5, 6)

artcher [175]

Answer with explanation:

The equation of line is, y= -x +3

→x+y-3=0---------(1)

⇒Equation of line Parallel to Line , ax +by +c=0 is given by, ax + by +K=0.

Equation of Line Parallel to Line 1 is

x+y+k=0

The Line passes through , (-5,6).

→ -5+6+k=0

→ k+1=0

→k= -1

So, equation of Line Parallel to line 1 is

x+y-1=0

⇒Equation of line Perpendicular to Line , ax +by +c=0 is given by, bx - a y +K=0.

Equation of Line Perpendicular to Line 1 is

x-y+k=0

The Line passes through , (-5,6).

→ -5-6+k=0

→ k-11=0

→k= 11

So, equation of Line Parallel to line 1 is

x-y+11=0

the volume of a cube is increasing at a constant rate of 824 cubic centimeters per minute. At the instant when the volume of the

Maurinko [17]

Answer:

DA/dt = 75.27 cm²

Step-by-step explanation:

Cube Volume = V(c) = 683 cm³

DV(c) /dt = 824 cm³

V(c,x) = x³

Then

DV(c,x)/ dt = 3x² Dx/dt

( DV(c,x)/ dt )/ 3x² = Dx/dt (1)

Now as V(c,x) = x³ when V(c,x) = 683 cm³ x = ∛683

x = 8.806 ( from excel)

And by subtitution of this value in equation (1)

Dx/dt = ( DV(c,x)/ dt )/ 3x² ⇒ Dx/dt = 824 / 3*x²

Dx/dt = 824 /3*77.55

Dx/dt = 824/232,64

Dx/dt = 3,542

Then we got Dx/dt where x is cube edge. The area of the face is x² then

the rate of change of the suface area is

DA/dt = ( Dx/dt )²*6 ( 6 faces of a cube)

DA/dt = (3.542)²*6

DA/dt = 75.27 cm²
