Answer
33
Step-by-step explanation:
11 of the faces is a square.
\begin{aligned} \text{Area of a square} &= \text{side} \cdot \text{side}\\\\ &= 3 \cdot 3\\\\ &= {\blueD{9}} \\\\ \end{aligned}
Area of a square
=side⋅side
=3⋅3
=9
Hint #22 / 4
444 of the faces are triangles. Each triangle has the same base and height.
\begin{aligned} \text{Area of a triangle} &= \dfrac12 \cdot \text{base} \cdot \text{height}\\\\ &= \dfrac12 \cdot 3 \cdot 4\\\\ &= 6 \\\\ \end{aligned}
Area of a triangle
=
2
1
⋅base⋅height
=

⋅3⋅4
=6
The total area of these 444 triangles is 4 \cdot 6 = \greenD{24}4⋅6=244, dot, 6, equals, start color #1fab54, 24, end color #1fab54.
Hint #33 / 4
Let's add the areas we found to find the surface area.
\begin{aligned} \text{Surface area} &= \blueD{9}+ \greenD{24}\\\\ &= 33\\\\ \end{aligned}
Surface area
=9+24
=33
Hint #44 / 4
The surface area of this square pyramid is 333333 units^2

Answer:
Scalar product
Step-by-step explanation:
The scalar product of a matrix refers to the product of a matrix and a number. The scalar is used to multiply each element in the matrix to get the final vector. In the question the scalar is k which is a constant and the matrix is A.
in the example below 2 is the scalar
![2*\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]](https://tex.z-dn.net/?f=2%2A%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%262%263%5C%5C4%265%266%5C%5C7%268%269%5Cend%7Barray%7D%5Cright%5D)
the final matrix will be
![\left[\begin{array}{ccc}2&4&6\\8&10&12\\14&16&18\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%264%266%5C%5C8%2610%2612%5C%5C14%2616%2618%5Cend%7Barray%7D%5Cright%5D)
THE FACTOR TREE IS : 8=2^3
Answer:
16 gallons
Step-by-step explanation:
If you don't know the derivative of the inverse of sine, you can use implicit differentiation. Apply sine to both sides:
(true for <em>y</em> between -π/2 and π/2)
Now take the derivative of both sides and solve for it:
