Is 13 a rational number? And why

Mathematics
1 answer:
Semenov [28]3 years ago
8 0

Answer: A rational number is a number that can be expressed as a fraction where both the numerator and the denominator in the fraction are integers. The denominator in a rational number cannot be zero if you’re working with a number with a long line of different decimals, then your number is irrational! If you’re working with an integer or a number with terminal or repeating decimals (like 1.333333), then your number is rational! and 13 is a rational number since it can be written as a fraction as well like 13/1

Otrada [13]

Answer:

f(0) = -6

f(1) = -4

f(2) = 2

f(3) = 12

Step-by-step explanation:

f(x)=2x^{2} -6\\f(0)=2(0)^{2}-6=0-6=-6\\ f(1)=2(1)^{2}-6=2-6=-4\\ f(2)=2(2)^{2}-6=2(4)-6=8-6=2 \\f(3)=2(3)^{2}-6=2(9)-6 =18-6=12

Given f(x) = x2 - x3, find f(-10).
postnew [5]
Please, use the symbol "^" to denote exponentiation.

f(x) = x^2 - x^3.

f( -10) is found by substituting  -10 for x in the given equation (immediately above):

f( -10) = ( -10)^2 - ( -10)^3, or  -100 + 1000, which equals 900.

Which of the following tables shows the correct steps to transform x2 + 10x + 24 = 0 into the form (x − p)2 = q?
kkurt [141]

The correct steps to transform x² + 10x + 24 = 0 into the form (x − p)² = q is

d.

Step 1: x² + 10x + 24 + 1 = 0 + 1

Step 2: x² + 10x + 25 = 1

Step 3: (x + 5)² = 1

To transform x² + 10x + 24 = 0 into the form (x − p)² = q where [p and q are integers], we perform the following steps of transformation.

<h3>What is transformation?</h3>

This is process of converting one expression to the other by performing some mathematical operations.

<h3>How to transform x² + 10x + 24 = 0 into the form (x − p)² = q </h3>

x² + 10x + 24 = 0

We add 1 to both sides.So,

Step 1: x² + 10x + 24 + 1 = 0 + 1

Thus, we have

Step 2: x² + 10x + 25 = 1

Since the left-hand-side x² + 10x + 25 = (x + 5)²

So, we have

x² + 10x + 25 = 1

Step 3: (x + 5)² = 1

So, the correct steps to transform x² + 10x + 24 = 0 into the form (x − p)² = q is

d.

Step 1: x² + 10x + 24 + 1 = 0 + 1

Step 2: x² + 10x + 25 = 1

Step 3: (x + 5)² = 1
