Stephanie put $80 in her bank account when she was five years old. The bank gave her a simple interest rate of 2.1%. Does she ha
OLEGan [10]

Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the amount deposited.

P represents the principal or amount deposited.

R represents interest rate

T represents the duration in years.

From the information given,

P = 80

R = 2.1%

T = 10 years

I = (80 × 2.1 × 10)/100 = $16.8

The total amount that she would have after 10 years is

80 + 16.8 = $96.8

She wouldn't have enough money to buy a TV for $1,000

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
drek231 [11]
<h3>Answer:</h3>

g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11

<h3>Step-by-step explanation:</h3>

A polynomial with zero "a" will have (x -a) as a factor. Your 3rd-degree polynomial will have the three factors ...

... f(x) = (x -(-4))·(x -(-3))·(x -1)

This will have a y-intercept of (4·3·(-1)) = -12. In order to move it to -11, we need to vertically scale this function by a factor of 11/12. Then our poynomial is ...

... g(x) = (11/12)(x+4)(x+3)(x-1)

Multiplying this out, you get ...

... g(x) = (11/12)x³ +(11/2)x² +(55/12)x -11

A 30 Oz box of Lucky Charms cost $4.50 a 20 oz box cost $3.60 what is the unit price of each box
notka56 [123]

We need to find the unit price of each box.

So, a box that weighs 30 Oz costs $4.50.

lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.

Unitary method is a process to find the value of a single unit.

Now,

30 Oz costs $4.50

therefore, 1 Oz should cost:

\frac{4.50}{30} =0.15 dollars

So, the unit price of box 1 is $0.15.

Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.

Now,

20 Oz box costs $3.60

therefore, 1 Oz should cost:

\frac{3.60}{20} =0.18 dollars

So, the unit price of box 2 is $0.18.
