In the scientific value of 5.893 x 10n. The standard value is 0.00005893 what is n? To better illustrate this phenomenon, we can explain it further under the rules of scientific notation. 
For example. 
1. 
 3 x 10^3 = 3 x 100 = 300
 
2.  3 x 10^-3 = 3 x 0.001 = 0.003 

Solution: 
0.00005893 = 5.893 x 0.00001 = 5.893 x 10^-5   
n= ^-5

A rectangle has a perimeter of 68 inches it’s length is 2 inches less than 3 times the width what is the area of the rectangle

Answers

Answer:

225 inches²

Step-by-step explanation:

Let the length be l and width be w

Condition 1

2l+2w=68 (Perimeter=68)--------(i)

Condition 2

l=3w-2 ---------(ii)

Putting equation (ii) in (i)

2(3w-2)+2w=68

6w-4+2w=68

8w-4=68

8w=68+4

8w=72

dividing both sides by 8

w=9 inches

now putting w=9 in (ii)

l=3(9)-2

l=27-2

l=25 inches

Now

Area of rectangle =  l × w

=9 × 25

=225 inches²

Answer: Length = 25 in., width = 9 in.

How does the CONSTANT affect a line graph?

Answers

In a simple slope intercept formula: y=mx+b, b is the constant, because b is not affect by another varible. To make this easier to understand, say we have the equation y=2x+9. No matter what x and y are, b or the 9 in this case will never change. You will ALWAYS be adding that nine. Therefore, it is the constant.

Which of the following gives all of the sets that contain squrt 9the set of all irrational numbers
the set of all natural numbers, the set of all whole numbers, and the set of all integers
the set of all integers, the set of all rational numbers, and the set of all real numbers
the set of all natural numbers, the set of all whole numbers, the set of all integers, the set of all rational numbers, and the set of all real numbers

Answers

Answer:

Option C (the set of all integers, the set of all rational numbers, and the set of all real numbers).

Step-by-step explanation:

The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.

As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.

As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.

After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers, Therefore, Option C is the correct answer!!!

Answer:

the set of all integers, the set of all rational numbers, and the set of all real numbers
