1. 5 is an irrational algebraic number. 3 is an irrational algebraic number. In other words, the square root of 2 is irrational. So Square root of 1 is the rational.

2. You are indeed correct. An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number. If it is written in decimal notation, an irrational number would have an infinite number of digits to the right of the decimal point, without repetition.

A man claims to have extrasensory perception (ESP). As a test, a fair coin is flipped 23 times, and the man is asked to predict

77julia77 [94]

The probability that he would have done at least this well if he had no ESP is 0.99979

<h3>What is the probability of determining that he would have done well with no ESP?</h3>

To determine the probability, we need to first find the probability of doing well with ESP.

The probability of having 20 correct answers out of 23 coin flips is:

$\mathbf{=(\dfrac{1}{2})^{20}}$

Since we have 20 correct answers, we also need to find the probability of getting 3 answers wrong, which is:

$\mathbf{=(\dfrac{1}{2})^{3}}$

There are $(^{23}_{20})$ = 1771 ways to get 20 correct answers out of 23.

Therefore, the probability of doing well with ESP is:

$\mathbf{= 1771 \times (\dfrac{1}{2})^{20}} \times (\dfrac{1}{2})^{3}}$

= 0.00021

The probability that he would have at least done well if he had no ESP is:

= 1 - 0.00021

= 0.99979

Differentiating Exponential functions In Exercise,find the derivative of the function. See Example 2 and 3.

Citrus2011 [14]

Answer:

$f'(x)=-5ae^{ax}=a f(x)$ , where a be a constant.

Step-by-step explanation:

Note: The given functions is a constant function because variable term is missing.

Consider the given function is

$f(x)=-5e^{ax}$

where a be a constant.

We need to find the derivative of the function.

Differentiate with respect to x.

$f'(x)=\dfrac{d}{dx}(-5e^{ax})$

$f'(x)=-5\dfrac{d}{dx}(e^{ax})$

$f'(x)=-5e^{ax}\dfrac{d}{dx}(ax)$ $[\because \dfrac{d}{dx}(e^x)=e^x]$

$f'(x)=-5ae^{ax}$

$f'(x)=a(-5e^{ax})$

$f'(x)=a f(x)$

Therefore, the derivative of the function is $f'(x)=-5ae^{ax}=a f(x)$ .

The circumference of a great circle of a sphere is 44π. Find the Surface Area of the sphere.

alexdok [17]

Answer:

1936 π square units

Step-by-step explanation:

Given the information:

<em>The circumference of a great circle of a sphere is 44π.</em>

As we know the formula used to find a circle's circumference is:

C = 2πr , where r is the radius of the circle

In this situation, we know C = 44π

<=> 2πr = 44π

<=> r = 22 units

Hence, the Surface Area of the sphere

S.A = 4π $r^{2}$

= 4π $22^{2}$

= 1936 π square units
