Step-by-step explanation:

c ^ 3/2

Let c = 4

4 ^ 3/2

Rewriting 4 as 2^2

2 ^2 ^3/2

We know that a^b^c = a^(b*c)

2 ^(2*3/2)

2 ^3

Find the second derivative, do not have to simplify

zlopas [31]

$f(x)=\sec(\pi x)=\dfrac{1}{\cos(\pi x)}=[\cos(\pi x)]^{-1}\\\\\text{use}\\\\(a^n)'=na^{n-1}\\\\(\cos x)'=-\sin x\\\\f'(g(x))=f'(g(x))\cdot g'(x)$

$f'(x)=\left\{[\cos(\pi x)]^{-1}\right\}'=-[\cos(\pi x)]^{-2}\cdot[-\sin(\pi x)]\cdot\pi\\\\=\dfrac{\pi\sin(\pi x)}{[\cos(\pi x)]^2}=\pi\dfrac{\sin(\pi x)}{\cos(\pi x)}\cdot\dfrac{1}{\cos(\pi x)}\\\\=\pi\tan(\pi x)\sec(\pi x)$

Margaret [11]

Answer:

Make payments on or before the due date; Pay off the full amount with the first monthly statement; Have a plan of how you will repay the money.

Explanation:

Good credit practices will help build your credit.

You must pay at least the minimum amount due each month in order to avoid late fees and derogatory marks on your credit report. This means the first option is not correct.

Making payments on or before the due date will keep your account in good standing. This option is correct.

Paying off the full amount with the first monthly statement, while it does not help y

our credit score much, will keep your account in good standing. This option is correct.

Having a plan of how you will repay the money you borrow is essential before you start borrowing. This option is correct.

Choosing the credit card with the highest interest rate will cause you to pay more over the lifetime of the balance. This is not something you want; this option is not correct.

Suppose that each day a company has fixed costs of 400 dollars and variable costs of 0.8x+1420 dollars per unit, where x is the

Bess [88]

Answer:

Step-by-step explanation:

Given that a company fixed costs are 400 dollars

and variable cost = $0.8x+1420$ per unit and x the no of units produced

Selling price = $1500-0.25x$ per unit

a) Break even units

At break even units selling price = variable cost

$1500-0.25x=0.8x+1420\\1.05x = 80\\x=76.19~76$

Break even units = 76

b) Revenue = Sales - total costs

= $x(1500-0.25x)-(x)(0.8x+1420)-400\\= 1500x-0.25x^2-0.8x^2-1420x-400\\= -1.05x^2+80x-400$

Use derivative test to get max revenue

R'(x) = $-2.10x+80$

R"(X) <0

So maximum when I derivative =0 or when

$x=38.10$

x=38

c) price when x =38 is

$P = 1500-0.25(38)\\=1490.5$
