7 0

Answer:

90, B

Step-by-step explanation:

3 x 3 = 9

3 x 3 = 9

6 x 3 = 18

6 x 3 = 18

6 x 3 = 18

6 x 3 = 18

9 + 9 + 18 + 18 + 18 + 18 = 90

Question 4: Finding a basis of the orthogonal complement Consider the matrix Find a basis of the orthogonal complement of the co
pickupchik [31]

Answer: hello your question is poorly written hence I will provide the required matrix

answer :

A = \left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]

Step-by-step explanation:

Given that the basis of the orthogonal complement have been provided already by you in the question I will have to provide the Matrix

The required matrix

\left[\begin{array}{ccc}1&0&1\\0&1&1\\1&-1&0\end{array}\right]

column1 = column 3 - column2

where column 3 and column 2 are the basis of the orthogonal complement of the column space of the Matrix

How to solve x=2y and 6y-3x=18 by using subsitution
BARSIC [14]

Answer:

This system of equations has no solutions

Step-by-step explanation:

in the linear equations, if the variable is disappeared, and

  • The two sides of the equation are equal, then the equation has infinitely many solutions
  • The two sides of the equation are not equal, then the equation has no solutions

Let us solve the question

∵ x = 2y ⇒ (1)

∵ 6y - 3x = 18 ⇒ (2)

→ Substitute x in equation (2) by the value of x in equation (1)

∵ 6y - 3(2y) = 18

∴ 6y - 6y = 18

∴ 0 = 18

→ 0 can not equal 18

∴ Left hand side ≠ Right hand side

→ From the 2nd note above

∴ This system of equations has no solutions

What is the sum of the measures of interior the angles of a 25-gon
Dovator [93]

Answer:

4,140 degrees

Step-by-step explanation:

Mathematically, the sum of interior angles of a polygon is;

(n-2)180

where n is the number of sides the polygon has

Mathematically;

we will be replacing n by 25 here

So, we have;

(25-2)180

= 23 * 180 = 4,140 degrees

suppose the acceleration function of an object moving along a line is given by a(t) =0.2t. find the position of the object if yo
Alexandra [31]

Answer:

See below

Step-by-step explanation:

sf = s0 + v0 t  + 1/2 at^2

        1  + (-3)t + 1/2 (.2t) t^2           ( weird acceleration value)

s =  1 -3t + .1 t^3           You will need a 't' value to determine the position
