A credit card had an APR of 15.98% all of last year, and compounded interest daily. What was the credit card's effective interes

zimovet [89]

Answer:

Option(B) is the correct answer to the given question.

Step by Step Explanation

We know that

$A\ =\ P \ *(\ 1+\ \frac{r}{n} \ ) ^{nt}$

Here A=amount

r=15.98%=0.1598

n=365

t=1

Putting these values into the equation

$A\ =\ P \ *(\ 1+\ \frac{0.1598}{365} \ ) ^{365}$

$A\ =\ P \ *(\ 1+\ 0.000437) ^\ { 365}$

$A\ =\ P \ *(\ 1.000437 ) ^{365}$

$A\ =1.17288 P$

Now we find the interest

I= $1.17288P\ -P\\=\ 0.17288P\\\ ~ 0.1720P$

Therefore effective interest rate of the last year can be determined by

$\frac{0.1720P}{P}$

=0.1720 *100

=17.20%

Suppose Q is the midpoint of PR. Use the information to find the missing value.

murzikaleks [220]

Step-by-step explanation:

If Q is the midpoint of PR

Then PQ + QR = PR

(6x + 25) + (16 - 3x)

group the same terms and add them

(6x - 3x) + (25 + 16)

Hence PR = (3x + 41)

But to find the value of PR....If Q is the midpoint....then PQ = QR...since they are both half lengths of PR;

; 6x + 25 = 16 - 3x

; 6x + 3x = 16 - 25...;9x = -9

Hence the value of...x = -1

Then substitute the value of x into the equation of PR....3x + 41

;3(-1) + 41

;-3 + 41

Hence PR = 38

F(x)=9x^3+2x^2−5x+4 and g(x)=5x^3−7x+4.

Gennadij [26K]

$f(x)-g(x) = 2x(2x^2+x+1)$

Further explanation:

Given functions are:

$f(x)=9x^3+2x^2-5x+4\\g(x)=5x^3-7x+4$

In order to find f(x)−g(x), g(x) will be subtracted from f(x)

$f(x) -g(x) = 9x^3+2x^2-5x+4 - (5x^3-7x+4)\\= 9x^3+2x^2-5x+4-5x^3+7x-4\\= 9x^3-5x^3+2x^2-5x+7x+4-4\\=4x^3+2x^2+2x\\=2x(2x^2+x+1)$

Hence,

$f(x)-g(x) = 2x(2x^2+x+1)$
