Answer:

Step-by-step explanation:

the lenght is y, the width is also y since the base is a square and since the height is twice the lenght it will be 2y, knowing that we just find the total surface area in terms of y.

which would be: 2(y·y) + 2(y·2y) + 2(2y·y)=360

this then simplifies to= 10y²=360

= y²=36

= y =6

the height therefore is 2y meaning its 2(6)=12

this problem was rather easy its so sad no one helps out in here totally hate this site wish more people helped

Makayla borrows $15200. Some is from her friend at 5% annual interest, 2 times as much as that from her bank at 8% , and the rem

GalinKa [24]

Answer:

Amount borrowed from friend = 4000

From Bank = 8000

From insurance = 3200

Step-by-step explanation:

Given that:

Amount borrowed = $15200

Let amount borrowed from friend = x

x at 5% = 0.05x

From Bank = 2x at 8% = 0.08*2x = 0.16x

From insurance = 15200 - (x + 2x) at 4%

From insurance = 15200 - 3x at 4% ; (15200 - 3x)* 0.04 = 608 - 0.12x

Interest paid in first year = $968

Simple interest = principal * rate * time

968 =

968 = (0.05x + 0.16x + 608 - 0.12x)

968 - 608 = 0.05x + 0.16x - 0.12x

360 = 0.09x

x = 360 / 0.09

x = 4000

Hence,

Amount borrowed from friend = 4000

From Bank = 2x = 4000 * 2 = 8000

From insurance = 15200 - (4000 + 8000) = 3200

What is the polynomial function of lowest degree with lead coefficient 1 and roots i, –2, and 2?

dimulka [17.4K]

We are given roots of a polynomial function : i, –2, and 2.

And leading coefficient 1 .

We need to find the polynomial function of lowest degree.

<em>Please note: We have one root i, that is a radical root. And a radical always comes in pair of plug and minus sign.</em>

Therefore, there would be another root -i.

So, we got all roots of the polynomial function : i, -i, -2, and 2.

For the given roots, we would have factors of the polynomial (x-i)(x+i)(x+2)(x-2).
