Use the discriminant to describe the roots of each equation. Then select the best description. x2 - 5x + 7 = 0
miv72 [106K]
The general form of a quadratic (second degree) equation is 

a x^{2} +bx+c=0, where

D= b^{2}-4ac is called the Discriminant.


The Discriminant determines how many roots the equation will have as follows:

i)  if D>0, the equation has 2 roots.
ii) if D=0, the equation has 1 double root.
iii) if D<0, the equation has no roots.


In our equation, x^{2} -5x+7=0, a=1, b=-5, c=7

so the discriminant is D=(-5)^2-4*1*7=25-28<0


Thus the equation has no roots.


Remark: the equation has no roots in the Real numbers, but it has 2 roots in a larger set of numbers to be discussed in the future, the Complex numbers.

The perimeter of a regular 6 -sided figure is 30 units, and the length of each side is x + 1 units.
iren [92.7K]

Answer:

x = 4

Step-by-step explanation:

since each side is equal to x + 1 and there are 6 sides, to get x alone, you have to subtract 1, six times from the perimeter.

1 × 6 = 6

30 - 6 = 24

then divide that by the number of sides (6)

24 ÷ 6 = 4

x = 4!

Please help fast! Rosa's friend Jake claims that he can read minds. To test Jake's abilities, Rosa chooses 3 different numbers
grigory [225]

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

\mathbf{n = 10} --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

  • 1st guess = 1/10
  • 2nd guess = 1/9
  • 3rd guess = 1/8

So, the required probability is:

\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}

\mathbf{Pr = \frac{1}{720} }

Hence, the probability that Jake's guesses are correct is 1/720
