Answer:

no because a rational number is any number that can be expressed as the quotient of two integers, with the denominator not equal to zero.

Answer:

she is correct

Step-by-step explanation:

rational numbers are not whole numbers, and -3 is a whole number. For example, -1/3 is a rational number, but -3 is not.

Sorry if im wrong, im bad at math :(

Consider the following sequence: -5, -1, 3,...

Alika [10]

Answer:

a. it is arithmentic - this is because for each term there is a constant increase of 4, and the change between each term <u>doesn't change</u>

b. you need to find the nth term, by using the equation difference x n + 0th term: the difference is (+)4 and the 0th term is -9 (-5 is the 1st term, so to go one back we subtract 4 - the inverse operation), so the nth term is 4n -9. Now we do the inverse operation on 119 to see if it's a term (it is a term if it's an integer. So, first we do 119 <u>plus</u> 9 (inverse of - 9) to get 128, then divide it by 4 rather than multiplying. This gives us 32, and that tells us that 119 is the 32nd term of the sequence.

A square and a circle intersect so that each side of the square contains a chord of the circle equal in length to the radius of

krek1111 [17]

Answer:

Step-by-step explanation:

it is given that Square contains a chord of of the circle equal to the radius thus from diagram

$QR=chord =radius =R$

If Chord is equal to radius then triangle PQR is an equilateral Triangle

Thus $QO=\frac{R}{2}=RO$

In triangle PQO applying Pythagoras theorem

$(PQ)^2=(PO)^2+(QO)^2$

$PO=\sqrt{(PQ)^2-(QO)^2}$

$PO=\sqrt{R^2-\frac{R^2}{4}}$

$PO=\frac{\sqrt{3}}{2}R$

Thus length of Side of square $=2PO=\sqrt{3}R$

Area of square $=(\sqrt{3}R)^2=3R^2$

Area of Circle $=\pi R^2$

Ratio of square to the circle $=\frac{3R^2}{\pi R^2}=\frac{3}{\pi }$

The definition of a circle uses the undefined term _______.

Alecsey [184]

Answer:

C. Plane

Step-by-step explanation:

One definition of a circle is: "It is the set of all points in a plane that are at a given distance from a fixed point."

The undefined term is the word "plane."

You could define a plane as a flat surface with zero thickness and extends infinitely in all directions, but it isn't in the definition of a circle.

Euclid defined a plane as "a surface that lies evenly with the lines on it" before he defined a circle, so the meaning was understood.

A, B, and D are wrong. They aren't mentioned in the definition.

The stock of Company A lost $4.17 throughout the day and ended at a value of

Anit [1.1K]

Answer:

Step-by-step explanation:

After losing 4.17, it came down to 100.08, so the opening price was:

100.08 + 4.17 = 104.25

To find percentage decline, we find the ratio of the "change" (which is 4.17) divided by the opening (original) price, which is 104.25. Then we multiply that fraction by 100 to get our percentage decline.

So,

$\frac{4.17}{104.25}*100=4$

Thus, the

percentage decline = 4%
