How many times larger is 1.9 × 10^-8 is than 4.2 × 10^-13<br><br>please help​
Jet001 [13]

Answer:

hope this helps!

Step-by-step explanation:

You have to divide:

1.9x10^-8 ÷ (4.2x10^-13)

= appr .45 x 10^5

= .45 x 100000

= appr 45,000 times as large

PLEEEEEEEAAAAAAAAAASSSSSSSSSEEEEEEE a wee this quickly<br>How did he get answer A
Simora [160]

Answer:

To get answer A,  Dave took 47*5 = 235

Step-by-step explanation:

There are 147 containers that contain 5 gallons each.  We need to multiply to find the total number of gallons.

total number of gallons = containers * number of gallons per container

                                       = 147* 5 gallons per container

                                        =735 gallons

To get answer A,  Dave took 47*5 = 235

Given points A(-1, -2) and B(2, 4) where AP: BP=1:2, find the locus of point P.​
koban [17]

Answer:

x^2 + 4x + y^2 +8y  =  0

Step-by-step explanation:

Given

A = (-1,-2)

B = (2,4)

AP:BP = 1 : 2

Required

The locus of P

AP:BP = 1 : 2

Express as fraction

\frac{AP}{BP} = \frac{1}{2}

Cross multiply

2AP = BP

Calculate AP and BP using the following distance formula:

d = \sqrt{(x - x_1)^2 + (y - y_1)^2}

So, we have:

2 * \sqrt{(x - -1)^2 + (y - -2)^2} = \sqrt{(x - 2)^2 + (y - 4)^2}

2 * \sqrt{(x +1)^2 + (y +2)^2} = \sqrt{(x - 2)^2 + (y - 4)^2}

Take square of both sides

4 * [(x +1)^2 + (y +2)^2] = (x - 2)^2 + (y - 4)^2

Evaluate all squares

4 * [x^2 + 2x + 1 + y^2 +4y + 4] = x^2 - 4x + 4 + y^2 - 8y + 16

Collect and evaluate like terms

4 * [x^2 + 2x + y^2 +4y + 5] = x^2 - 4x + y^2 - 8y + 20

Open brackets

4x^2 + 8x + 4y^2 +16y + 20 = x^2 - 4x + y^2 - 8y + 20

Collect like terms

4x^2 - x^2 + 8x + 4x + 4y^2 -y^2 +16y + 8y  + 20 - 20 =  0

3x^2 + 12x + 3y^2 +24y  =  0

Divide through by 3

x^2 + 4x + y^2 +8y  =  0

The table shows values for functions
Studentka2010 [4]

Answer:

The study examined stochastic stability of EEG samples recorded in succession from the same healthy volunteer at unchanged state. The absence of statistical repetitions not only for EEG samples, but also for the corresponding spectral densities was proven. A method to calculate the pairwise comparison matrices of ECG samples and quasi-attractors was proposed. The diagnostic effectiveness of these calculations was demonstrated during photostimulation, when successive EEG samples chaotically changed under overall homeostatic conditions.

... It was about the need for a third science that W. Weaver spoke about in 1948 [8]. Now it is the theory of chaos-self-organization, which, according to K. Gödel's theorem, has gone beyond the bounds of deterministic and stochastic science -DSS [9][10][11][12][13][14][15][16][17][18]. ...

... that the European Association of Cardiology recommends registering the heart rate for at least 5 minutes (for example, the parameters of the cardio intervals). At the same time, it is believed that during this period a sample of 300 (or more) cardio intervals will be obtained, and this sample should be quite representative [14][15][16][17][18]. ...

... What kind of evidence-based medicine can we talk about in the study of cardiovascular system if 85% or more of the compared cardio intervals samples do not statistically coincide (they do not belong to the same general population)? Obviously, further use of stochastic methods is not advisable [14][15][16]20-23] for cardiovascular system studying, which was pointed out by W. Weaver [8]. ...

... These special properties of the TTS (complexity) are based on the lack of statistical stability of any samples of the components of the state vector of any biosystem x=x(t)=(x1, x2, …, xm)T, where xi(t) represents the parameters of the biosystem. This was first proved in the form of the Eskov-Zinchenko effect (EZE) in biomechanics [5][6][7][8][9][10], and then for other biosystems [11][12][13][14][15][16]. The EZE extends not only to samples of tremorograms (TMG), teppinggrams (TPG), electromyograms (EMG), RR intervals (RR) and other parameters of the human body, but also to their spectral densities of signals (SDS), autocorrelations A(t) and other characteristics xi(t). ...

... Elements of this matrix (see table 1) represent the Newman-Keuls test p for pairwise comparison of TMG samples. If p≥0.05, then this compared pair of TMG can be attributed to one (same) sampled population [11][12][13][14][15][16]. From table 1, it follows that the number k1=7 of such pairs is extremely small. ...
