Answer:

It can be written as 825/1000. You can simplify this to get the simplest form which would be 33/40. All decimals are out of one, they are a part. When you first get a decimal, put the numbers such as 825 on top. The last number is in the thousandths place, so it is out of 1000. 1000 is your denominator. Your fraction is then 825/1000. From here you can simplify if possible.

The marginal totals are the sum of each row and column.

For example, the total number of sophomores is 120 + 302 = 422.

3x^2+x-5=0 to 2 decimal place<br> 3x^3+2x-4=0 to 2 decimal place

Schach [20]

Answer:

1. 3/5

2. 1.219841

3. 2 - f(2)/7

4. -1.9682

5. 1.502446

Step-by-step explanation:

If we call

then the second approximation to the root of the equation f(x)=0 would be

hence

Here we have

Let's start with

then

Since the first 6 decimals of and are equal, the desired approximation is 1.219841

If the line y = 4x − 1 is tangent to the curve y = f(x) when x = 2, then f'(2) = 4*2 - 1 = 7, so

Here

We want to find all the values x such that

or what is the same, the x such that

so, let f(x) be

and let's use Newton's method to find the roots of f(x).

Since

f is strictly increasing, and since

f(1) = e+3-9 = e - 6 < 0

and

f has only one root in [1,2]

By using Newton's iterations starting with

Since then

x=1.50244564 is the desired root.

The answers as a comma-separated list would be

1, 1.573899431, 1.503982961, 1.502446348, 1.50244564

The answer rounded to six decimal places would be

1.502446

José stood on a 4 foot high still, then jumped into a 1 foot deep hole. Which applies to his action

mina [271]

I'm going to assume that you are asking how deep he jumped. He jumped from 4 feet high into a 1 foot deep hole, so, we need to add.

4 + 1 = 5

Therefore, Jose jumped a total of 5 feet.

Best of Luck!

Answer:

It can be decomposed into the following simplest shapes:

TWO RECTANGLES AND ONE TRIANGLE

Step-by-step explanation:

You can observe in the picture attached that it can be decomposed into the following simplest shapes:

Two Rectangles.

One Triangle.

Because,

The area of the a rectangle can be found with:

A= lw

Where "l" is the length and "w" is the width.

You can identify in the picture that:

lA: 14 ft

Wa: 13ft -7ft= 6ft

1b= 20 ft

wb= 7ft

So, Substituting the values, you get that the areas of the rectangles A and B are:

Aa: (14ft) (6ft)= 84ft²

Ab: (20ft) (7ft) = 140ft²

The formula for the area of a triangle is:

A= $bh/2$

Where "b" is the base and "h" is the height.

In this case:

b= 20ft- 14ft= 6ft

h= 6ft

Then, its area is:

Ac = $(6ft) (6ft)/2$

which iis 18ft²

Then, it will bring the total area of carpet that Valerie needs:

At= Aa+ Ab+ Ac

At= 84ft² + 140ft² + 18ft²

At= 242²
