A credit card bill for $559 was due on September 14. Purchases of $289 were made on September 19, and $15 was charged on Septemb

Sunny_sXe [5.5K]

Answer: $623

Step-by-step explanation:

calculation of Finance charge due on October 14

(+) $ 559 due on sep 14, $ 559 * (19.5*31) / (100 * 365) = $ 9.20

(+) purchase $ 289 on sep 19, $ 289 * (19.5*26 ) / (100 * 365) = $ 2.42

(+) finance charge on sep 28, $ 18 *(19.5*17 ) / (100 * 365) = $ 0.17

(-) Repayment on 25 sep , $ 250 * (19.5*20 ) / (100 * 365) = (2.745)

Total finance charges from 14 sep to 14 oct = $ 9.7= appr. 10

Amount due on 14 October = $559+$289+$15+$11.855- $250

= $ 623

Ivan purchased stock in a company at an initial price of $8 per share. The share value reached $18 after 10 days and then began

Butoxors [25]

The quadratic equation that best represents his model of the relationship between stock value and time is given by:

$y = -0.0976(x - 10)^2 + 18, x \geq 0$

The graph is given at the end of the answer.

<h3>What is the equation of a parabola given it’s vertex?</h3>

The equation of a quadratic function, of vertex (h,k), is given by:

$y = a(x - h)^2 + k$

In which a is the leading coefficient.

In this problem, the maximum value was a share value of $18 after 10 days, hence the vertex is:

(h,k) = (10,18).

Thus:

$y = a(x - 10)^2 + 18$

Since the initial price was of $8 per share, we have that:

$8 = a(0 - 10)^2 + 18$

$-82a = 8$

$a = -\frac{8}{82}$

$a = -0.0976$

Hence the equation is:

$y = -0.0976(x - 10)^2 + 18, x \geq 0$

At the end of the answer, the sketch of the graph is given.

Charlie used one and two thirds cups of walnuts and two and one sixth cups of cranberries to make breakfast bread.How many cups

quester [9]

Answer:

5/6 cups

Step-by-step explanation:

2/3 -walnuts

1/6-cranberries

2/3+1/6

common denominator-12

2/3 ·4/4=8/12

1/6 · 2/2= 2/12

8/12+2/12=10/12

10/12=5/6
