Answer:

4y - x = 20

Step-by-step explanation:

y-y1 = m (x-x1)

y - 6 = 1/4 (x - 4)

4y - 24 = x - 4

5/9 = ?/54 whats the answer

Shkiper50 [21]

Answer:

30/54

Step-by-step explanation:

1st make and equation so 5/9=x/54

now cross-multiply.

5/9=x/54

(5)*(54)=x*(9)

270=9x

you can flip the equation.

9x=270 (next divide both sides by 9)

x=30

so 30/54=5/9

hope this helps :)

Area of the rectangle ==> 9x13 =117 cm²

Area of the right triangle ==> 11x(5)/2 =55/2 cm²

Total area = 117 + 55/2 = 289/2 = 144.5 cm²

Prove that the curve a(t) = (cost, sin 2t, cos 2t) is regular on R and that it self-intersects at (1,0,1). Check the self-inters

alexandr402 [8]

Answer:

The function a (t) is a vector function composed of the component functions $a_ {1} (t) = cost, a_ {2} (t) = sin2t$ and $a_ {3} (t) = cos2t$ . How $a_ {1} (t), a_ {2} (t), a_ {3} (t)$ are infinitely derivable functions in R, so they are regular functions in R.

Now, for $t = 0$ , you have to $a (0) = (cos (0), sin2 (0), cos2 (0)) = (1, 0, 1)$ . How the functions $a_ {1} (t), a_ {2} (t), a_ {3} (t)$ are periodic functions with period $2 \pi,$ the vector function $a (t)$ will take the same point $(1, 0 , 1)$ at $t = 2n\pi, n = 0, 1, 2, 3, ...$ then the vector function is auto-intercepted
