What real life object could a triangular prism be used for

1 answer:

4 0

We can start out simple, so here's some:

If you ever drew a sea saw as a child, or seen it, you probably had seen a part that looks like a triangular prism. It's somewhere in the structure.

Many building infrastructures have them. The roofs of many houses are pointed in some what of a triangle like shape so that rain water can roll off of them easier.

Hope these two help or at least spark some ideas!

The function f is defined by f(x)=2x^2-4.<br> Find f(-x)

Vedmedyk [2.9K]

First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.

Find the linear approximation of the function f(x, y, z) =

ser-zykov [4K]

Answer:

See below in bold.

Step-by-step explanation:

f(x, y, z) = x^2 + y^2 + z^2 at (6, 6, 7)

Taking partial derivatives

f'x = 2x + y^2 + z^2 --> f'x(6,6,7) = 12+36+49= 97

f'y = x^2 + 2y + z^2---> f'y(6,6,7) = 36 + 12 + 49 = 97

f'z = x^2 + y^2 + 2z ----> f'z(6,6,7) = 36 + 36 + 14 = 86.

f(6,6,7) = 36 + 36 + 49 = 121

So our linear approximation is:

L(x,y,z) = 121 + 97(x - 6) + 97(y - 6) + 86(z - 7)

Substituting the given values

f(6.012, 5.972,6.982)

= L(6.012, 5.972, 6.982) ≈ 121 + 97(6.012 - 6) + 97(5.972 - 6) + 86(6.982 - 7)

= 117.9.
