A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.

vesna_86 [32]

Let's simplify step-by-step.

2(3x+5)−4(x−1)

Distribute:

=(2)(3x)+(2)(5)+(−4)(x)+(−4)(−1)

=6x+10+−4x+4

Combine Like Terms:

=6x+10+−4x+4

=(6x+−4x)+(10+4)

=2x+14

On a huge site in San-Diego the whole new street of houses was constructed. To put the numbers on all new buildings the plates w
Papessa [141]
<h2>There are 45 houses on the left and require 95 plates, while there are 44 houses on the right and require 94 plates</h2>

Step-by-step explanation:

   Houses are numbered from 1 to 99. So, there are 99 houses. Odd-numbered houses are on the left. So, there are 50 houses on the left, while there are 49 houses on the right.

For houses on left : The houses are numbered 1, 3, 5, 7, 9, 11, 13..... 97, 99

   So 5 houses( 1, 3, 5, 7, 9) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = 5\textrm{x}1+45\textrm{x}2 = 95 plates.

For houses on right : The houses are numbered 2, 4, 6, 8, 10, 12, 14.... 96, 98

   So 4 houses( 2, 4, 6, 8) require only one plate for numbering, while the remaining 45 houses require 2 plates each. So total number of plates = 4\textrm{x}1+45\textrm{x}2 = 94 plates.

∴ There are 45 houses on the left and require 95 plates, while there are 44 houses on the right and require 94 plates.

Find the second derivative y= x^2lnx
Dimas [21]
First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx

now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
         1+2+2lnx
         3+2lnx is the answer
