What is the value of the function at x=−3?

20 points! Help! Which of the following visual representations correctly displays a relationship between sets of real numbers? T

Contact [7]

<h2>Answer:</h2><h2>The correct option to the given question is J</h2>

Step-by-step explanation:

Real numbers are classified into two types,

(i) Rational numbers - A number which can be expressed as fraction, ratio or percentage is called as rational number

(ii)Irrational numbers - A number which is not rational, (i.e) cannot be expressed as a ratio or percentage is called as irrational number.

Since there are no common numbers in rational and irrational, they cannot be expressed as "G" option.

Real numbers are formed by the union of rational and irrational numbers.

Let a be a rational number and b be an irrational number. Which of the following are true statements?(there is more than 1 answe

kramer

<span>A.) the sum of a and b is never rational.
This is a true statement. Since an irrational umber has a decimal part that is infinite and non-periodical, when you add a rational number to an irrational number, the result will have the same infinite non periodical decimal part, so the new number will be irrational as well.

</span><span>B.) The product of a and b is rational
This one is false. Zero is a rational number, and when you multiply an irrational number by zero, the result is always zero.

</span><span>C.) b^2 is sometimes rational
This one is true. When you square an irrational number that comes from a square root like </span> $\sqrt{2}$ , you will end with a rational number: $( \sqrt{2} )^{2}=2$ , but, if you square rationals from different roots than square root like $\sqrt[3]{2}$ , you will end with an irrational number: $\sqrt[3]{2^{2} } = \sqrt[3]{2}$ .

<span>D.) a^2 is always rational
This one is false. If you square a rational number, you will always end with another rational number.

</span><span>E.) square root of a is never rational
</span>This one is false. The square root of perfect squares are always rational numbers: $\sqrt{64} =8$ , $\sqrt{16} =4$ ,...

F.) square root of b is never rational
This one is true. Since the square root of any non-perfect square number is irrational, and all the irrational numbers are non-perfect squares, the square root of an irrational number is always irrational.

We can conclude that given that<span> a is a rational number and b be an irrational number, A, C, D, and F are true statements.</span>

laurens suv was detected exceeding the posted speed limit of 60 kilometers per hour , how many kilometers would she have been tr

Vlada [557]

Answer:

60 kilometers per hour (kmph) over the limit

Step-by-step explanation:

The speed limit is 60 kmph

Let's find his original rate:

We know D = RT

Where

D is the distance, in km

R is the rate, in kmph

T is the time in hours

He went 10 km in 5 minutes, so we need the time in hours, first. That would be:

5/60 = 1/12 hour

So, putting into formula, we find rate:

D = RT

10 = R(1/12)

R = 10/(1/12)

R = 10 * 12

R = 120 kmph

He was going over by:

120 - 60 = 60 kmph

Factor out 1/4 out of 1/4x+11/4

cluponka [151]

$\frac{1}{4} x+\frac{11}{4}$

we can rewrite it as

$\frac{1}{4}* x+\frac{1}{4}*11$

we can see that 1/4 is in multiple in both terms

so, we can factor it out

so, we get

$\frac{1}{4}( x+11)$ ..............Answer
