I can’t say the answer but what I would do is find what 15% of it is then take that amount and add it to the cost and boom there is your answer

I need help, if you give answer ASAP I’ll reward a lot of points!!
Gnoma [55]

Answer:

A = 31.875 inches squared

Step-by-step explanation:

Area of a parallelogram is bh

b = 12 and 3/4 is just 12.75 inches

h = 2 and 1/2 is just 2.50 inches

Multiply these together and you get the area,

A = (12.75)(2.50) = 31.875 inches squared

If the side length of a cube is 40 what is the surface area
Elodia [21]
A cube has 6 sides.

A cube is all made up of squares.

So, we need to find the area of one cube and multiply that by 6.

Length * width= area

40*40= 1,600

Multiply that by 6.

1,600*6= 9600

Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.

9,600 (the unit) ^2

I hope this helps!

Which of the following is NOT equivalent to the nxn matrix A being invertible? A. The homogeneous system associated to A has a u
storchak [24]

Answer:

Option C

Step-by-step explanation:

  • For the matrix A of order n\times n to be invertible, its determinant must not be equal to zero, |A| \neq0, A^{- 1}  exists if- AC = CA = I, where I is identity matrix.
  1. The homogeneous equation with coefficient matrix A has a unique solution:

       AB = 0, B = A^{- 1}.0 = 0

      Thus, B = (0, 0, 0......., 0) is a unique solution

     2. The non - homogeneous equation system with coefficient matrix A has  a unique solution:

For an equation- AY = D

Y = A^{- 1}.D is a unique solution

     3. Every non homogeneous equation with coefficient matrix A is not consistent as:

For an equation- AY = D, has a solution.l Thus coefficient matrix is inconsistent whereas augmented matrix is.

      4. Rank of matrix A = n, Thus the column space of A is R^{n}

      5. Since, column space of A = R^{n}, thus x→xA is one-to-one

PLEASE ANSWER ASAP
mote1985 [20]

Answer:

y = 2(3)^{x}

Step-by-step explanation:

For the exponential function in the form

y = ab^{x}

Use ordered pairs from the table to find a and b

Using (0, 2 ), then

2 = ab^{0} ( b^{0} = 1 ) , thus

a = 2, so

y = 2b^{x}

Using (1, 6 ) , then

6 = 2b ( divide both sides by 2 )

b = 3

Thus the exponential function is

y = 2(3)^{x}
