Answer:

The total amount of money in a saving account after t years is given by:

A = 1000(1.023)^t

we can write this function as;

A = 1000(1+0.023)^t             .....[1]

Use the formula:-

A = P(1+\frac{r}{n})^{nt} ; where

P = Principal amount (the initial amount borrow or deposit)


r= annual rate of interest (as a decimal)

t = number of years the amount is deposited or borrowed for.

A =amount of money accumulated after n years, including interest.

n = number of times the interest per year  

Now, the function can be rewritten to identify the monthly interest rate is;

A = P(1+\frac{0.023}{12})^{12t}

here, n =12 ;

For monthly rate of interest =  \frac{r}{12} = \frac{0.023}{12} =0.0019(approx) or 0.19% .

Therefore, the approximate monthly rate of interest is, 0.19%

The function is A=1000(1.023 1/2)^12t
and the interest is 0.19%

C + 6 &gt; 5c - 2<br>solved and proof​
Elena L [17]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

c < 2

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

c+6>5c - 2\\--------------\\\\\rightarrow5c - 2< c + 6 \leftarrow \text{Notice how the sides are switched.}\\\\\rightarrow 5c - c -2 < c - c + 6\\\\\rightarrow 4c -2 < 6\\\\\rightarrow 4c - 2 + 2 < 6 + 2\\\\\rightarrow 4c  < 8\\\\\rightarrow \frac{4c

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

(PLEASE HELP) Question is worth 30 points:) The following function represents the production cost F(x) In dollars for x numbers
soldi70 [24.7K]

Answer:

production cost f(x), in dollars, for x number of units produced by company 1:

f(x) = 0.05x^2 − 7x + 300

2) Table that represents the production cost g(x), in dollars, for x number of units produced by company 2:

x        g(x)

0.6     899.58

0.8     899.52

1        899.50

1.2     899.52

1.4     899.58

3) Comparison: do a table for f(x) with the same x-values of the table for g(x).

x            f(x) = 0.05x^2 − 7x + 300    g(x)

0.6         295.818                               899.58

0.8         294.432                               899.52

1            293.05                                 899.50

1.2         291.672                               899.52

1.4          290.298                              899.58

As you can see the values of f(x) are consistently lower than the values of g(x) for the same x-values.

The minimum production cost for company 2 is around 899.50 at x = 1, while the minimum production cost of company 1 is defintely lower (lower than 292.298 for sure, in fact if you find the vertex it is 55).

Answer: Based on the given information, the minimum production cost for company 2 is greater.
