Answer:

C. x = -61/5

Step-by-step explanation:

7(x+5)+4(x+5) = 6x-6

First let's multiply the parenthesis parts.

7x+35 + 4x+20 = 6x-6

Combine like terms - combine all the x terms and the number terms. 7x + 4x = 11x, 35+20 = 55

11x + 55 = 6x - 6

Subtract 6x from both sides

5x + 55 = -6

Subtract 55 from both sides

5x = -61

x = -61/5

Find all the critical points of h(x) = x^3 − 3x^4 and categorize them as local

neonofarm [45]

Answer:

0 is an inflection point

1/4 is a local maximum.

Step-by-step explanation:

To begin with you find the first derivative of the function and get that

$h'(x) = 3x^2 - 12x^3$

to find the critical points you equal the first derivative to 0 and get that

$3x^2 - 12x^3 = 0, x = 0,1/4$

To find if they are maximums or local minimums you use the second derivative.

$h''(x) = 6x-36x^2$

since $h''(0) = 0$ is neither an inflection point, and since $h''(1/4) = -3/4$ then 1/4 is a maximum.

Simplify this: log√24+ log6

Kitty [74]

simplifying $log\sqrt{24}+log6$ we get $log(12\sqrt{6})$

Step-by-step explanation:

We need to simplify: $log\sqrt{24}+log6$

Solving:

Applying the rule:

log a + log b = log(ab)

$log\sqrt{24}+log6\\=log(6\sqrt{24})\\\sqrt{24} = \sqrt{2*2*2*3} =\sqrt{2^2*6} =\sqrt{2^2} \sqrt{6}=2\sqrt{6}\\ Putting\,\,value:\\=log(6*2\sqrt{6})\\=log(12\sqrt{6})$

So, simplifying $log\sqrt{24}+log6$ we get $log(12\sqrt{6})$
