Please Mark Brainliest, you are an amazing person thank you and your welcome :D
Step-by-step explanation:
$54 / 6 = $9
The surface area (SA) of the triangular prism given above is the sum of its lateral area (LA) and the areas of its bases (BA).
SA = LA + 2 x BA
From the given above,
SA = 18 m² + 2 x 15 m² = 48 m²
Thus, the surface area of the solid is approximately 48 m².
Answer:
i dont know this it is hard
Step-by-step explanation:
I'm partial to solving with generating functions. Let
Multiply both sides of the recurrence by and sum over all .
Shift the indices and factor out powers of as needed so that each series starts at the same index and power of .
Now we can write each series in terms of the generating function . Pull out the first few terms so that each series starts at the same index .
Solve for :
Splitting into partial fractions gives
which we can write as geometric series,
which tells us
# # #
Just to illustrate another method you could consider, you can write the second recurrence in matrix form as
By substitution, you can show that
or
Then solving the recurrence is a matter of diagonalizing the coefficient matrix, raising to the power of , then multiplying by the column vector containing the initial values. The solution itself would be the entry in the first row of the resulting matrix.
Answer:
Some of the products do not show the correct powers of x.
Step-by-step explanation:
From the picture,
3x(2x - 1) = 6x² - 3x
The correct display on the tile should look like this :
_____+x ______ +x ______ +x
+x __ +x² ______+x² ______+x²
|
+x__ +x² ______ +x² ______+x²
|
- ___ -x _______ -x _______-x
+6x² - 3x
