Instructions: use the ratio of a 45-45-90 triangle to solve for the variables. Leave your answers as radicals in simplest form

Mathematics
1 answer:
DIA [1.3K]2 years ago
4 0

Answer:

v=14, u=14

Step-by-step explanation:

The 45-45-90 theorem states that the hypotenuse is \sqrt{2} times the bases of the triangle. So, to find one of the bases, we need to divide \sqrt{2}. Thus, \frac{12\sqrt{2} }{\sqrt{2} } = 12.

2. Write an expression to represent f (20)
Furkat [3]

Answer:

I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).

Step-by-step explanation:

So, my answer was f(20) = 64(1/2)^19

f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.

Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19

I hope this helps!

Describe the motion of a particle with position (x, y) as t varies in the given interval. (For each answer, enter an ordered pai
DerKrebs [107]

Answer:

The motion of the particle describes an ellipse.

Step-by-step explanation:

The characteristics of the motion of the particle is derived by eliminating t in the parametric expressions. Since both expressions are based on trigonometric functions, we proceed to use the following trigonometric identity:

\cos^{2} t + \sin^{2} t = 1 (1)

Where:

\cos t = \frac{y-3}{2} (2)

\sin t = x - 1 (3)

By (2) and (3) in (1):

\left(\frac{y-3}{2} \right)^{2} + (x-1)^{2} = 1

\frac{(x-1)^{2}}{1}+\frac{(y-3)^{2}}{4} = 1 (4)

The motion of the particle describes an ellipse.
