The given parabola will open; Down

<h3>How to interpret a parabola curve?</h3>

In parabolic curves, if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

Now, we are given the equation of the parabola s;

-36y = x²

divide both sides by -36 to get;

y = -x²/36

From the above it is clear that the leading coefficient is less than zero and as such the parabola will open in the downward direction.

9. A car dealership offers a loan with 4% interest for 48 months, and you plan to purchase a car for $20,000. You can afford a d

Lady bird [3.3K]

SOLUTION

Since you can afford a down payment of $2,500, the remaining money needed to purchase the car becomes

$\begin{gathered} 20,000-2,500 \\ =17,500 \end{gathered}$

Now, we will find the simple interest on $17,500 for 48 months, which is 4 years. This becomes

$\begin{gathered} I=\frac{PRT}{100} \\ I=\frac{17,500\times4\times4}{100} \\ I=2,800\text{ dollars } \end{gathered}$

(a) What will your monthly payment be? $

We will add this interest to the $17,500 and divide by 48 months to get the monthly payment. This becomes

$\begin{gathered} 17,500+2,800=20,300 \\ \frac{20,300}{48}=422.91666 \\ =422.92 \end{gathered}$

Hence, the answer is $422.92

(b) How much will you pay in total for the car? $

To get this, we add the $20,300 (that we divided by 48 months), to the initial down payment made. This becomes

$\begin{gathered} 20,300+2500 \\ =22,800 \end{gathered}$

Hence, the answer is $22,800

We have initially found the interest as 2,800 dollars.

Hence the answer is $2,800

dedylja [7]

Answer:

$1.36

Step-by-step explanation:

First, add together the prices of all the clothes:

18.28 + 42.39 + 12.97

= 73.64

Then, subtract this from 75:

75 - 73.64

= 1.36

So, he will have $1.36 left after buying the clothes
