Mathematics
1 answer:
MatroZZZ [7]3 years ago
6 0

Answer:

Step-by-step explanation:

y^2-22y+c

complete the square ax^2+bx+c is our old formula quadratic equation

we know that to find c we will divide b/2 and square it

22/2=11

c^2=121

we have y^2-22y+121

Prove sin^2A + cos^2A = 1
Nady [450]

Step-by-step explanation:

{sin}^{2} A +  {cos}^{2} A  = 1 \\ lhs =  {sin}^{2} A +  {cos}^{2} A  \\  =  {sin}^{2} A +  1 - {sin}^{2} A  \\  = 1 \\  = rhs \\  \therefore \:  {sin}^{2} A +  {cos}^{2} A  = 1 \\

ILL GIVE BRAINLIEST PLS HELP
yan [13]

Answer:

1/5

Step-by-step explanation:

The stick has a length of 5 units

The stick is broken at two points chosen at random

First break: the probability that you get a piece that is 1 unit or longer than 1 units= 1/5.

Second break, the probability that you get a piece that is 1 unit or longer than 1 units is 1/5.

Therefore,

The total probability =probability of first break * probability of second break * original stick unit

=1/5 * 1/5 * 5

= 1/25 *5

=5/25

=1/5

A is a 3 times 3 matrix with three pivot positions.
saw5 [17]

Answer:

The following are the answer:

In option a  "No".

In option b  "Yes".

Step-by-step explanation:

In choice a:

Ax = 0 has no nontrivial solution. A would be the three-pivot matrix, it may assume, that the function has no free variable, and only if the function has had at least one free factor are their nontrivial formulas for the equations of the form Ax=0.  

It implies that since A is a 3x3 matrix, has no free variables so that it has no non-trivial choices, and Ax = 0.

In choice b:

we assume that every potential has at least one solution that is Ax=b . If A does have a three-pivot matrix, It will be a pivot element for each row and column, and for each possible b∈ R³, Ax = b has at least one solution.
