Answer:
(x + 9)(5x - 1)
Step-by-step explanation:
Given
5x² + 44x - 9
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × - 9 = - 45 and sum = + 44
The factors are + 45 and - 1
Use these factors to split the x- term
5x² + 45x - x - 9 ( factor the first/second and third/fourth terms )
= 5x(x + 9) - 1(x + 9) ← factor out (x + 9) from each term
= (x + 9)(5x - 1) ← in factored form
Answer:1.965517241

Answer:
Step-by-step explanation:
A function satisfying the equation 
is said to be an even function. This denomination comes from the fact that the same relation is satisfied for functions of the form 
with 
even. Observe that if 
is twice differentiable we can derivate using the chaing rule as follows:
implies 
Applying the chain rule again we have:
implies 
So we have that function 
is also an even function.
Answer:
Step-by-step explanation:
22. √125 is closer to √121 or 11
23. √23.5 is closer to √25 or 5
24. ∛59 is closer to ∛64 or 4 (cubed)
(4 cubed = 64, 3 cubed = 27)
25. ∛430 is closer to ∛512 or 8
(512 - 430 = 82
430- 343= 87)
26. y² = 55 is equal to y = √55, Closer to √49 or 7
27. d² = 95 is equal to d = √95, Closer to √100 or 10
28. p² = 6.8 is equal to p = √6.8, Closer to √9 or 3
29. ∛210 is closer to ∛216 or 6 (cubed)
30. ∛520 is closer to ∛512 or 8 (cubed)
