Show all work to factor x4 − 10x2 + 9 completely.
leva [86]

Answer:

(x+1)(x-1)(x+3)(x-3)

Step-by-step explanation:

x4-10x^2+9

Group expression so that the coefficients of the x^2 terms add up to +9.

= x^4 -9x^2   - x^2+9

match coefficients in both groups

= x^4 -9x^2   - (x^2-9)

factor each group

= x^2 (x^2-9) - 1(x^2-9)

now factor out the common factor (x^2-9)

= (x^2-1)(x^2-9)

Finally, factor each quadratic factor

= (x+1)(x-1)(x+3)(x-3)

It’s about functions please help and show work.
r-ruslan [8.4K]

Answer:

f(-6) = -2

Step-by-step explanation:

plug in k value (-6)

f(-6) = -6/2 + 1

theres two ways to solve for this

one way:

convert the whole number 1 to an improper fraction

f(-6) = -6/2 + 2/2

combine like terms

f(-6) = -4/2

divide -4 by 2

f(-6) = -2

second way:

divide -6 by 2

f(-6) = -3 + 1

combine like terms

f(-6) = -2

either way you get the same answer

use whichever is easiest for you

For the sequence -28,-16,-4,8,... The expression that defines the nth term where a 1 =-28 is 12 - 28n 2 12 - 28(n - 1) 3. - 28 +
GrogVix [38]

Answer:

a₁ = -28

aₙ = a₁ + 12 (n-1)

Step-by-step explanation:

a₁ = -28

a₂ = -28 + 12 (2 - 1) = -16

a₃ = -28 + 12 (3 - 1) = -4

a₄ = -28 + 12 (4 - 1) = 8

aₙ = a₁ + 12 (n-1)

A function is defined as y = 2x + 4 with the domain of all real numbers greater than or equal to 4. What is the range of the fun
Liula [17]

Answer: y => 12

y is greater than or equal to 12

Step-by-step explanation:

So they give you the function of y = 2x + 4 and the domain of all real numbers is greater than or equal to 4.

In simple term, the domain is x => 4, x is greater than or equal to 4.

Using that we can substitute the x in the function by 4.

y = 2(4) + 4

y = 8 + 4

Which gave us the answer of 12.

Since the domain can be anything greater than 4 or 4. We can expect the

same for the range.

Then the range will be 12 or greater than 12. For example, 13, 14, 15, 16...

Ex. y = 2(5) + 4

y = 10 + 4

y = 14

Ex. y = 2(4.5) + 4

y = 9 + 4

y = 13

Pls help!!!<br> Find the missing side. (Round to the nearest tenth, if necessary)
tamaranim1 [39]

Answer:

7.8

Step-by-step explanation:

We can use pythagorean theorem (a^2+b^2=c^2) where a and b are sides of a right triangle and c is the hypotenuse.

x^2+13.3^2=15.4^2.

x^2=15.4^2-13.3^2\\

x^2=237.16-176.89\\x^2=60.27\\x=7.763

Rounded to the nearest tenth, x = 7.8
