Differentiate the following functions y=4x^3-2x^2+5x^-3.7-6

Katarina [22]

I don't think you copied it correctly, but I'll assume that you did.

y = 4x³ - 2x² + 5('x' to the -3.7 power) - 6

"y-prime" (the first derivative) = 12x² - 4x - 18.5('x' to the -4.7 power)

??? Anyone know how to do this ???

babunello [35]

Answer:

B. x ≤ 2.

Step-by-step explanation:

56 - 10x ≥ 20 + 8x

-18x ≥ -36

x ≤ -36/-18 = 2. ( Note that the inequality sign flips because we are dividing by a negative value).

A water molecule is made up of 3 atoms. One third of the atoms are oxygen and the remaining atoms are hydrogen. If there are 114

Mashcka [7]

Answer:

228 hydrogen atoms

Step-by-step explanation:

In a water molecule,

1/3rd is oxygen atoms, and

2/3rd (1 - 1/3 = 2/3) is hydrogen atoms

If there are 114 water molecules,

Total number of atoms would be:

3 * 114 = 342 (1 oxygen and 2 hydrogen atoms in 1 water molecule)

Out of these, 2/3rd would be hydrogen atoms, so:

$\frac{2}{3}*342=228$

There would be 228 hydrogen atoms

What is the value of x in the equation 6(x + 1) – 5x = 8 + 2(x – 1)?

ycow [4]

Answer:

$x=0$

Step-by-step explanation:

we have

$6(x+1)-5x=8+2(x-1)$

solve for x

$6x+6-5x=8+2x-2$

Group terms that contain the same variable and move the constants to the other side

$6x-5x-2x=8-2-6$

$-x=8-8$

$x=0$
