These two matrices are unable to be added due to dimensional mismatch? True, false, both, unable to answer with the info given

Mathematics

Hoochie [10]3 years ago

Answer:

false

Step-by-step explanation:

\left[\begin{array}{c}-4\end{array}\right] +\left[\begin{array}{c}7\end{array}\right] =\left[\begin{array}{c}3\end{array}\right]

Both of the matrices are 1 x 1 ("one by one"), so they can be added to produce a 1 x 1 matrix.

To add (or subtract) two matrices, they must be the same size.

(m x n) + (m x n) = (m x n)

m x n  means a matrix has  m  rows and  n  columns.  Dimensions are always named in that order:  rows, then columns.

Find the volume and explain please ASAP.
olya-2409 [2.1K]

Answer:

1395in^3

Step-by-step explanation:

First find the volume of the cuboid, 15in x 9in x 7in = 945in^3

Then find the volume of the rectangular pyramid using the formula V=lwh/3, the total height is 17in so subtract the height of the cuboid from the total height, giving you 10in.

V=(15in)(9in)(10in)/3 = 450in^3

450in^3 + 945in^3 = 1395in^3

Mekhanik [1.2K]

Answer:

Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan. If  then If  then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore Hence, { 19 + 0.39(x - 300), x > 300
