When deriving the quadratic formula by completing the square, what expression can be added to both sides of the equation to crea

nignag [31]

The expression that would be added to both sides is (b/2a)^2

<h3>How to determine the expression?</h3>

The equation is given as:

x^2 + b/ax + __ = c/a + __

Take the coefficient of x

b/a

Divide by 2

b/2a

Square the expression

(b/2a)^2

Hence, the expression that would be added to both sides is (b/2a)^2

Divide. Write your answer in simplest form. 6/7 ÷ 5/21

Serjik [45]

The answer is 8/5.
To divide fractions, flip the second fraction and multiply.
For example,
= 6/7 • 21/5
= 126/35
Simplify by dividing both sides by 7 to get your answer.
= 8/5

Find the maximum rate of change of f(x,y,z=x y/z at the point (2, -3, 5 and the direction in which it occurs. maximum rate of ch

kherson [118]

$f(x,y,z)=x+\dfrac yz$
$\implies \nabla f(x,y,z)=\left(1,\dfrac1z,-\dfrac y{z^2}\right)$
$\implies \nabla f(2,-3,5)=\left(1,\dfrac15,\dfrac3{25}\right)$

The maximum rate of change is then

$\|\nabla f(2,-3,5)\|=\dfrac{\sqrt{659}}{25}$

which occurs in the direction of $\nabla f(2,-3,5)$ above.

Tickets to a concert cost $2 for children and $5 for adults. If 630 people attended the concert and the ticket sales totaled $2,

sergeinik [125]

A) C + A = 630
B) 2C + 5A = 2,910 Multiplying A by -2
A) -2C -2A = -1,260 Then adding it to B
B) 2C + 5A = 2,910
3A = 1,650
A = 550

A) C + 550 = 630
Children's tickets = 80
