<h2>a) False</h2>

\frac{d}{dx} (f(x).g(x)) = f'(x).g(x) + g'(x).f(x)

<h2>b) False</h2>

\frac{d}{dx} ( \sqrt{x {}^{2}  + x} ) {}^{2}  =  \frac{2x + 1}{2 (\sqrt{x {}^{2}  + x}) {}^{2}  }  =  \frac{2(2x + 1)(x {}^{2} + x) }{2|x²+x|}  =  \frac{(2x + 1)(x { }^{2}  +x)}{|x²+x|}

<h3>Im assuming this is an absolute value</h3>

<h2>c) True</h2>

\frac{d}{dx} ( \sqrt{f(x)} ) =  \frac{f'(x)}{2 \sqrt{f(x)} }

<h2>Option C</h2>

Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.
Murrr4er [49]

Answer:

n = 5

Step-by-step explanation:

Given

2(n+1)! + 6n! = 3(n+1)!

Required

Find n

Simplify (n + 1)!

2(n+1)*n! + 6n! = 3(n+1)*n!

Factorize

n![2(n+1) + 6] = 3(n+1)*n!

Divide both sides by n!

2(n+1) + 6 = 3(n+1)

Open brackets

2n + 2 + 6 = 3n + 3

2n + 8 = 3n + 3

Collect like terms

2n - 3n = 3 -8

-n =-5

Multiply both sides by -1

n = 5

Write x2 − 6x + 7 = 0 in the form (x − a)2 = b, where a and b are integers.
Mariulka [41]
X² − 6x + 7 = 0

Let's complete the square [x²-6x+(??)²] -(??)² +7 = 0

As you noticed we have added the unknown square & also subtract the same so that not to change the equation

The question now is to calculate this square (??)²

We know that the middle term (6x) is twice the square root of the 1st times the square root of the 2nd, That is 6x=2x (multiply) √(??)²

6x = 2x?? & ??=6x/2x===> ?? =3 & (??)² =9

Hence plug (??)² into the equation above:

x² - 6x + 9 - 9 +7 =0

(x²-6x+9) -9 + 7 =0

(x-3)² -2 =0 ====> (x-3)² = 2 (that is B)

Solve x<br><br> 1.6x+3=21<br><br> 2.15(x - 5)=75
Alika [10]

Answer:

11.25

77.85

Step-by-step explanation:

1.6x + 3 = 21

use inverse operation (+ = -, x = ÷) by taking 3 to the opposite side and changing it's integer to negative

1.6x = 21 - 3

divide 2 sides by 1.6

1.6x = 18

1.6x/1.6 = 18/1.6

x = 11.25//

2.15(x-5)=75

inverse operation

x= 75 - 2.15 + 5

x= 77.85//
