Answer:

Orange, Blue, Red, Green.

Orange would be the best deal.

Step-by-step explanation:

In order to put the unit costs per square foot from least to greatest, let's find the unit cost per square root of each wrapping paper.

To find the unit cost per square root, we simply have to divide the cost over the amount of square feet. So:

Red:

c=\frac{1.79}{12.5}=\$0.1432\text{ per square foot}

Blue:

c=\frac{5.29}{40}=\$0.13225\text{ per square foot}

Green:

c=\frac{8.49}{50}=\$0.1698\text{ per square foot}

Orange:

c=\frac{6}{60}=\$0.10\text{ per square foot}

So, to cost of wrapping paper per foot from least to greatest is:

Orange, Blue, Red, Green.

So, orange would be the best deal.

And we're done!

You deposit $3000 in a savings account that earns 2.9% annual interest compounded monthly. You also save $80 per month in a safe
Jlenok [28]

Answer:

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be : 4048.17

Step-by-step explanation:

3000 deposit amount, 2.9 compound monthly interest .  save 80 dollars  per month at home .

A=p(1+r)^t

A=3000(1+0.029/12)^12t

A=3000(1.002417)^12t dollars

for the amount saved at home=80*12t=960t dollars

C(t)=3000(1.002417)^12t+960t

if T=1 year then the saving will be :

C(t)=3000(1.002417)^12t+960t

     =3088.17+960= 4048.17 dollars

Can you help me please ​
alexira [117]

Answer:

Please check the explanation.

Step-by-step explanation:

Given that

|v|=38

Ф = 120°

<u>Finding the horizontal component</u>

The horizontal component can be obtained using the formula

Vx = |v| cos Ф

     = 38 cos 120°

     = 38 (-0.5)

      = -19

Thus, the  horizontal component is:

Vx = -19

<u>Finding the vertical component</u>

The vertical component can be obtained using the formula

Vy = |v| sin Ф

    = 38 sin 120°

    = 38 (0.86)

    = 32.68

Thus, the vertical component is:

Vy = -19

  • A vector 'v' with magnitude |v| and direction Ф can be written as:

v = |v| cos Ф i + |v| sin Ф j

As

|v|=38

Ф = 120°

Thus, the vector is

v = 38 cos 120° i + 38 sin 120° j

or

v = -19 i + 32.68 j
