SA=(6,4*4)*2+(6,4*10,5)*2+(4*10,5)*2=269,6 square centimeters

I believe,this is it.

Since it is a juice box the dimensions fit to fold the box,so it's easy to guess looking the parts that need to match together.(I wrote on the image the dimensions that were ''lacking''...)

tiny-mole [99]

Answer:

30 years: 1.38

45 years: 2.07

65 years:2.99

Step-by-step explanation:

$1x0.046=0.046

0.046x30=1.38

0.046x45=2.07

0.046x65=2.99

this is assuming that it gets interest yearly and that they don't want the original amount included.

Find the area between y=(x-2)ex and the x-axis from x=2 to x=4.

mojhsa [17]

Answer:

$e^4+e^2$

Step-by-step explanation:

It can be found by integral.

First let's find the intersection points.

$(x-2)e^x = 0$

Only intersection point is x = 2.

And it is asked to find the area in the interval (2, 4).

$\int\limits^4_2 (x-2)e^x \,dx=?$

We will use integration by parts.

$x-2=u\\dx=du\\e^xdx=dv\\e^x=v$

$\int\limits^4_2 (x-2)e^x \,dx=uv-\int vdu=(x-2)e^x-\int e^xdx=(x-2)e^x-e^x=\\\\=(x-3)e^x|^4_2=(4-3)e^4-(2-3)e^2=e^4+e^2$

jocelyn bought 2 sweaters for the same price. she paid 23.56,including sales tax of 1.36 and a 5.00 discount coupon. what was th

wel

Number of sweaters bought by Jocelyn = 2
Price of the 2 sweaters including tax and discount coupon = 23.56
Amount of ales tax taken = 1.36
Amount of discount coupon = 5.00
Then
Price of 2 sweaters before tax = 23.56 - 1.36
   = 22.20
Then
Price of the sweater before discount coupon was applied = 22.20 + 5.00
   = 27.20
So
Price of 1 sweater before tax and coupon discount = 27.2/2
   = 13.6
So the price of 1 sweater before tax and coupon discount is 13.6.
