Yes it was reasonable. I say it is resonable because if you multiply 44 times 25 it is 1,100 so the estimate was close enough

Choose three intervals on the real number line that contain both rational and irrational numbers. Do you think that any given in
Helen [10]

Any real number line ranges from negative infinity to positive infinity. A real number number line consists of all the rational and irrational numbers. Let us take three intervals which contain both the rational and irrational numbers.

First interval:  [3,4]

Since every integer is a rational number, 3 and 4 are both rational. In this interval there occurs the value of π (3.14159..) which is an irrational number.

Second interval :  [0,2]

0 and 2 are integers and hence are rational. In this interval, occurs √2 (1.41421...) is an irrational number.

Third interval : [2,3]

In this interval, Eulers number 'e' lie whose value is (2.718281.. )

Hence we can conclude that, there occurs an irrational number between any two rational number.

I need help with this question I’ll give 15 points
weeeeeb [17]

Answer:

Calculating (5 x 2) violates the order of operations

Step-by-step explanation:

According to the order of operations, multiplies all have equal priority. Therefore, they must be evaluated left to right, not right to left. Evaluating (5 x 2) first is incorrect, and instead (9 x 5) should be calculated first.

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri
SOVA2 [1]

For this case we have a function of the form:

y = A * (b) ^ x

Where,

A: initial population of bacteria

b: growth rate

x: number of hours

Since the diameter is double every hour, then:

b = 2

We must now look for the value of A.

To do this, we evaluate an ordered pair of the graph:

For (1, 2):

2 = A * (2) ^ 1

Clearing A we have:

2 = A * 2

A = \frac{2}{2}\\A = 1

Then, the function is given by:

y = 1 * (2) ^ x

For after 9 hours we have:

y = 1 * (2) ^ 9\\y = 512

Answer:

the diameter of the bacteria after 9 hours is:

y = 512
