Stella [2.4K]2 years ago

4 0

Step-by-step explanation:

2(2+20)=80

4+40=80 (Distribute)

4+40-40=80-40(Subtract from both sides of the equation)

4=40(Simplify)

4/4=404/4(Divide both sides of the equation by the same term to get x=10)

=10

Abe is buying wrapping paper.

Answer:

So you need to compute all the rates to see which is the best deal.

$1.79/12.5ft^2=$0.1432 per ft^2

$5.29/40ft^2=$0.13225 per ft^2

$8.49/50ft^2=$0.1698 per ft^2

$6/60ft^2=$0.10 per ft^2

So the last option is the cheapes per square foot and thus is the best deal. Ordered from least to greatest.

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| $\neq$ 0, $A^{- 1}$ exists if- AC = CA = I, where I is identity matrix.

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

A cylinder has a base with a radius of 5 cm and a height of 15 cm. What is the volume of the cylinder? (Use π = 3.14.) A. 471 cm

eduard

The formula for volume is
$V=\pi r^{2}h$
We plug in:
$V=\pi (5)^{2}(15)$
$=\pi (25)(15)$
$=375\pi$
$=375*3.14=1177.5$
