Find the volume of the right triangular prism shown:

LekaFEV [45]

Answer:

960cm³

Step-by-step explanation:

Find the base of the triangle (use phytagoras theorem)

c²= a²+b²

20²= 16²+b²

400=256+b²

b²=400-256

b²= 144

$\sqrt{144}$

base= 12

Volume: (1/2×b×h)×l

= (1/2×12×16)×10

=(6×16)×10

=96×10

=960cm³

In this problem, x = c1 cos t + c2 sin t is a two-parameter family of solutions of the second-order DE x'' + x = 0. Find a solut

Norma-Jean [14]

Differentiate the given solution:

$x=C_1\cos(t)+C_2\sin(t) \implies x'=-C_1\sin(t)+C_2\cos(t)$

Now, given that x (π/4) = √2/2 … (I'm assuming there are symbols missing somewhere) … you have

$\dfrac{\sqrt2}2=C_1\cos\left(\dfrac\pi4\right)+C_2\sin\left(\dfrac\pi4\right)$

$\implies\dfrac1{\sqrt2} = \dfrac{C_1}{\sqrt2}+\dfrac{C_2}{\sqrt2}$

$\implies C_1+C_2=1$

Similarly, given that x' (p/4) = 0, you have

$0=-C_1\sin\left(\dfrac\pi4\right)+C_2\cos\left(\dfrac\pi4\right)$

$\implies 0=-\dfrac{C_1}{\sqrt2}+\dfrac{C_2}{\sqrt2}$

$\implies C_1=C_2$

From this result, it follows that

$C_1+C_2=2C_1=1 \implies C_1=C_2=\dfrac12$

So the particular solution to the DE that satisfies the given conditions is

$\boxed{x=\dfrac12\cos(t)+\dfrac12\sin(t)}$

(x+14)-(8-2x) equivalent to

kipiarov [429]

We are given the expression (x + 14) - (8 - 2x). The question is asking us to simplify this expression, and we can do that by first using the distributive property. This gives us x + 14 - 8 + 2x. Now, just combine like terms, which gives us 3x + 6. Therefore, the answer to your query is 3x + 6. Hope this helped and have a phenomenal day!
