1) Gathering the data

P=$6200

F=7310

t= 3 yrs

2) Since it is a simple interest, it is a linear application. So we can find it using this formula:

You are tasked with constructing a rectangular box with a square base, an open top, and a volume of 184 in3. Determine what the
Rudik [331]

The dimension of the box should be 1.7×1.7×3.58 in inches, applying minimization of surface area.

Dimensions to Minimize the Surface Area of the Box

It is given that the box is square based with an open top.

⇒ The box has one square and 4 rectangles

Thus, the total surface area of the box is given as,

S= a²+ab+ab+ab+ab  

S= a²+4ab ______________ (1)

Here, a is the side of the squared base and length of the rectangular sides of the box, b is the breath of the rectangular sides of the box.

This equation is later used for minimization of the surface area.

Also, the volume, V = a²b

It is also given that volume of the box is 184 in³.

⇒ 184 = a²b _____________ (2)

Forming a One-Variable Equation

From equation (2), b=184/a²

Now, substitute this value of b in equation (1) to get,

S = a² + 4a(184/a²)

S = a² + 4(184/a)

S = a² + 736/a

Minimization of Surface Area to find the Dimension

We require a dimension that will minimize the surface area of the box. Hence, applying minimization surface area, dS/da = 0

dS/da = 2a -736/a²

0 = 2a -736/a²

⇒ 0 = 2a³- 736

2a³ = 736

a³ = 736/2

a³ = 368

a = ∛368

a= 7.17 in

∵V = a²b

184 = (7.17)²b

b = 184/7.17²

b = 184/51.4089

b = 3.58 in

Therefore, 1.7×1.7×3.58 in inches is the required dimension for the box, using minimization of surface area..

HELP ASAP!!! i dont have too much points to give but i really need the help
Rama09 [41]

Answer:

Step-by-step explanation:

When I was 11, I took my first online Algebra 1 class.  This experience was totally new to me, I had never simply had to figure out anything by myself, I always had a teacher to explain the problem.   Sometimes, when I became frustrated with a problem, I procrastinated and fell behind schedule which lead to later consequences (like missing hanging out with friends). I quickly learned that being persistent and setting my own schedule was necessary to staying on-track.  

    Time management is crucial to online learning.   Since you can choose when to do your online classes, they are convenient to work on but also very easy to ignore when your real classes (classes that have in-class due dates) have actual teachers who will reprimand and embarrass you in front of the whole class if you fail to complete the work.

    Another thing I have  learned while taking online classes is that taking notes and rereading text is vital to your understanding of the material.  If you only skim through a lesson, you won't remember it.  Also, if the class provides practice problems or self-check quizzes, always do them to check your understanding.

I am currently taking two online classes, trigonometry and English 1, I sincerely hope that this will help you.  Best of luck in your online learning experience!
