Answer:
The quick answer: No.
Step-by-step explanation:
(pinquancaro)
Given : Number 0.040040004.....
To find : Is the number is rational or irrational ?
Solution :
Rational number is defined as number written in form of p/q where p and q are integers and q is non-zero.
Rational number is terminating and repeating.
Irrational number is defined as number which cannot be written in form of p/q.
Irrational number is non-terminating and non-repeating.
The number given is 0.040040004..... is non-terminating and non-repeating.
Therefore, The number 0.040040004..... is an irrational number.

Factor the following expression completely. 4b^8-61b^4+225
Solve for value of B
Answer:
b = 6
Step-by-step explanation:
[tex](6b - 7) \degree + 90 \degree + 61 \degree = 180 \degree \\ \\ (6b - 7) \degree + 151 \degree = 180 \degree \\ \\ (6b - 7) \degree = 180 \degree - 151 \degree\\ \\ (6b - 7) \degree = 29 \degree \\ \\ 6b - 7 = 29 \\ \\ 6b = 29 + 7 \\ \\ 6b = 36 \\ \\ b = \frac{36}{6} \\ \\ \huge \purple{ \boxed{ b = 6}}[/tex]

Write an equation in Standard Form of the line passing through (5, -4) with a slope of -2/5.
Answer:
The answer is
[tex]y = - \frac{2}{5} x - 2 \\ [/tex]Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the points is (5, -4) and slope - 2/5
The equation is
[tex]y + 4 = - \frac{2}{5} (x - 5) \\ y + 4 = - \frac{2}{5} x + 2 \\ y = - \frac{2}{5} x + 2 - 4[/tex]
We have the final answer as
[tex]y = - \frac{2}{5} x - 2 \\ [/tex]

What is the factored form of this expression?
-9x^3 - 12x^2 - 4x
A. x(3x - 2)(3x + 2)
B. -x(3x + 2)^2
C. x(3x - 2)^2
D. -x(3x - 2)(3x + 2)
Answer:
B
Step-by-step explanation:
Given
- 9x³ - 12x² - 4x ← factor out - x from each term
= - x(9x² + 12x + 4) ← perfect square
= - x(3x + 2)(3x + 2)
= - x(3x + 2)² → B
-9x^3-12x^2-4x
Factor out -x from the expression
-x×(9x^2+12x+4)
Using a^2+2ab+b^2=(a+b)^2 Factor the expression
-x×(3x+2)^2
now we do the same thing only different way ok
9x^2+12x+4
write the number in the exponential form with an exponent of 2
3^2 x^2+12x+4
write the expression as a product with the Factors 3x and 2
3^2 x^2 +2×3x×2+4
write the number in the exponential form with an exponent of 2
3^2 x^2+2×3x×2+2^2
Multiply the terms with equal exponents by multiplying their bases
(3x)^2+2×3x×2+2^2
Using a^2+2ab+b^2=(a+b)^2 Factor the expression
(3x+2)^2
Solution: -x×(3x+2)^2
answer:B

What are the domain and range of the function f(x)=3x-1 /2
Answer:
f(x)=3x−1
2
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

If a,b,c,d, and e are non negative such that x^6-289x^4-x^2+289=(x-a)(x+b)(x_c)(x+d)(x^2+ex+1), what is the value of a+b+c+d+e?
Answer:
36
Step-by-step explanation:
Hello,
If [tex]X=x^2[/tex] it becomes
[tex]X^3-289X^2-X+289=(X^2-1)(X-289)[/tex]
and [tex]289=17^2[/tex]
[tex]X^2-1=(X-1)(X+1)=(x^2-1)(x^2+1)=(x+1)(x-1)(x^2+1) \\\\x^2-289=x^2-17^2=(x-17)(x+17)[/tex]
So,
[tex]x^6-289x^4-x^2+289=(x^2-1)(x^2+1)(x^2-289)=(x-1)(x+1)(x+17)(x-17)(x^2+1)[/tex]
a = 1
b = 1
c = 17
d = 17
e = 0
Then a + b + c + d + e = 36

One student began to factor 40 as 4×10. Another student began with 2×20. Will they get different answers? Explain
Answer:
Yes because 4x10 and 2x20 are both two different equations/
Step-by-step explanation:
Answer:
They will get the same answer
Step-by-step explanation:
40 = 4*10 = 2*2 * 2*5
40 = 2*20 = 2 * 4*5 = 2 * 2*2*5
