P² - 12 p - 13 = 0 

Δ = ( -12)² - 4 ( 1 * - 13) 
Δ = 144 + 52
Δ = 196 = 14²

x₁ = (- ( -12) + 14 ) / 2 = 26/2 = 13 
x₂ = ( - ( -12) - 14) /2 = - 2 /2 = - 1

Answer:

The solutions of the given equations are -1 and 13.

Step-by-step explanation:

The given equation is

p^2-12p=13

Subtract 13 from both the sides.

p^2-12p-13=0

Middle term can be written as -13p+p,

p^2-13p+p-13=0

p(p-13)+1(p-13)=0

(p+1)(p-13)=0

Using zero product property, equal each factor equal to 0.

p+1=0\Rightarrow p=-1

p-13=0\Rightarrow p=13

Therefore the solutions of the given equations are -1 and 13.

Q#1: Suppose that you have two different algorithms for solving a problem. To solve a problem of size n, the first algorithm use
svetlana [45]

Answer:

The one of -[n+2n+3n+4n]/nlne(10) has fewer operations because the value of n is <u>static</u><u>.</u>

The one of n! ( factorial ) is factorised up to n∞ hence has infinity operations.

One grocery clerk can stock a shelf in 20 min. A second clerk requires 45 min to stock the same shelf. How long would it take to
Lorico [155]

<u>Answer: </u>

clerk A and clerk B can simultaneously stock a shelf in \frac{180}{13} minutes

<u>Explanation:</u>

Let the first clerk be A and the second clerk be B

A can stock a shelf in 20 min

B can stock a shelf in 45 min

Consider the complete work to be W

A’s rate of stocking = \frac{W}{20} per minute

B’s rate of stocking = \frac{W}{45} per minute

When, A and B work simultaneously, rate of work done = \frac{W}{20}+\frac{W}{45}

Total work done simulatenously = \frac{W}{\frac{W}{20}+\frac{w}{45}}

=\frac{20 * 45}{20+45}

Therefore, clerk A and clerk B can simultaneously stock a shelf in \frac{180}{13} minutes
