A)
1,16,81,256,\underline{625}\\
\text{The general formula is } n^4 \text{ where } n\in \mathbb{N}

b)
1,1,2,4,7,13,24,\underline{44}\\
\text{Each number is the sum of three preceding numbers.}

A) 1, 16, 81, and 256 are all perfect squares. Find their squares:
1, 4, 9, 14.
In this sequence, you first at 3, then 5, then 7. So, logically, you would add 9 next. 14 + 9 is 23, and 23 squared is 529.
b) I'm not sure the data points for this sequence are correct. I'd have to guess 42 based on this difference chart:
1    1    2     4     7     13     24   42
  +0  +1  +2    +3   +6   +11  +18
      +1  +1  +1    +3   +5   +9
         +0  +0   +2   +2   +4
            <u>+0   +2  +0   +2</u>

In the figure below, the two triangular faces of the prism are fight triangles with sides of length 3, 4, and 5. The other three
olasank [31]
The figure of the prism is attached below.

The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.

Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.

Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units

There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.

So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units

The Surface Area of the prism will be:

Surface Area = 2 (4) + 72 = 84 square units

Thus the correct answer is option A

) dy 2x<br> ------ = ---------------<br> dx yx2 + y
larisa86 [58]

Step-by-step explanation:

\dfrac{dy}{dx} = \dfrac{2x}{y(x^2 + 1)}

Rearranging the terms, we get

ydy = \dfrac{2xdx}{x^2 + 1}

We then integrate the expression above to get

\displaystyle \int ydy = \int \dfrac{2xdx}{x^2 + 1}

\displaystyle \frac{1}{2}y^2 = \ln |x^2 +1| + k

or

y = \sqrt{2\ln |x^2 + 1|} + k

where I is the constant of integration.
