The black figure is an ellipse, and the black line segment is is major axis. What is the length of the blue line segment?
NeTakaya

Answer:

D

Step-by-step explanation:

The formula we need to solve this is:

d_1+d_2=2a

Where

d_1  is the distance from one focus to the vertex

d_2  is the second distance from another focus to same vertex

<u>Note:</u> Here, vertex point is the point on top. The common point from which the RED and BLUE line meets the 2 foci

a  is half the length of the major axis (which is 9 here since total major axis is given as 18)

<em>Now we can plug into the equation and solve:</em>

<em>d_1+d_2=2a\\8.5+d_2=2(9)\\8.5+d_2=18\\d_2=18-8.5\\d_2=9.5</em>

<em />

<em>D is the correct answer.</em>

Integral of ln times cube root x dx
zvonat [6]
If u = ln(x^(1/3))
then by the chain rule
du = [1/x^(1/3)] * (1/3)x^(-2/3) dx = (1/3)(1/x) dx. 
You could get there faster by noting that
 ln(x^(1/3)) = (1/3) ln(x), so du = (1/3) dx/x

Classify the numbers by writing them in the appropriate section of the Venn Diagram 1) L. 136, 8, 7, V140, V4,8, V8 , 2.89 Real
saveliy_v [14]

<em>EXPLANATION:</em>

Classification of numbers according to the Venn diagram:

<em>Rational numbers:</em>

These numbers are represented by a fraction a / b, where a and b are integers and also b is different from zero.

<em>Whole numbers</em><em>:</em>

An integer is a natural number that can be positive or negative.

<em>Natural numbers:</em>

Natural numbers are those that start at zero to infinity are clearly positive.

<em>Rational numbers:</em>

When taking the square root of 8, 36 and 4 the result is an exact value that is why they are considered as rational numbers.

<em>Irrational Numbers:</em>

When the root of a number is not exact but is expressed as an infinite decimal as in the case of the square root of 140 which is 11.83215956619; this is an irrational number, also this result cannot be expressed as a fraction.
