Whats the square of a negative number?
Doss [256]

Answer:

A negative number squared is a positive number. Squaring is multiplying a number by its self.

Step-by-step explanation:

X^2 = x * x

Squaring something is just multiplying it by its self.

A negative times a negative = a positive

A positive times a positive = a positive

A negative times a positive = a negative

A positive times a negative = a negative

- * - = +

+ * + = +

- * + = -

+ * - = -

Here is how my 6th grade teacher helped me to remember it:

If something bad (-) happens to a bad guy (-), that is good.

If something good (+) happens to a good guy (+), that is good.

If something bad (-) happens to a good guy (+), that is bad.

If something good (+) happens to a bad guy (-), that is bad.

I hope I helped!

Let me know if you need anything else!

What binomial is a factor of the trinomial x^2-5x+4
Svetradugi [14.3K]

Explanation:

Let the equation be

a

⋅

x

2

+

b

⋅

x

+

c

. To factorize multiplication of a and c i.e. ac so that sum of factors, if ac is positive (and difference if ac is negative) is equal to b. Now split b into these two components and factorization will be easy.

                  Find the circumference of the circle and show work. [refer to  

                  attachment]

\large\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}

          Formula for Circumference of a Circle:-

        \dashrightarrow\star\bigstar\boxed{\boxed{C=2\pi r}}}

Where

  • C = circumference
  • π = pi (3.14…)
  • r = radius, which in this case is equal to 8

Substitute the value of r and solve:-

         C=2π(8)

        On simplification,

     

C=16π

On further simplification,

C=50.3

Therefore, we conclude that the circumference of this circle is

\dashrightarrow\star\bigstar\boxed{\boxed{\underline{\bold{C=50.3\:yd}}}}\bigstar\star\dashleftarrow

<h3>Good luck.</h3>

Suppose that you have 7 green cards and 5 yellow cards. The cards are well shuffled. You randomly draw two cards without replace
wlad13 [49]

Answer:

a. 7/22

b. 28/33

c. 7/22

d. dependent events

Step-by-step explanation:

The total number of cards is given as 7 + 5 = 12.

The probability if a card being green on the first pick, P(G) =  7/12

The probability of a card being yellow on the first pick, P(Y) = 5/12

Because there is no replacement, the card are going to be short by one card. Therefore, the second pick will be like this:

P(GG)  = ( 7/12×6/11)

P(GY) = ( 7/12 × 5/11)

P(YG) = ( 5/12×7/11)

P(RR) = ( 5/12 ×4/11)

a. P (G1 and G2) = ( 7/12×6/11)

                          = 7/22

b. P( At least one is green) = ( 7/12×6/11) +  ( 7/12 × 5/11) + ( 5/12×7/11)

                           = 28/33

c. P(G2G1)           = 7/22

d. the events are dependent. They do not give the same result.
