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

Mrs Grey is buying decorative ribbon of three different colors: blue, silver, and yellow. Blue ribbon is sold in rolls of 15 met

olganol [36]

Answer:

4 rolls of blue ribbon,

5 rolls of silver ribbon,

3 rolls of yellow ribbon.

Step-by-step explanation:

We have been given that Mrs Grey is buying decorative ribbon of three different colors: blue, silver, and yellow. Blue ribbon is sold in rolls of 15 meters, silver is sold in rolls of 12 meters, and yellow comes in rolls of 20 meters.

As Mrs. Grey needs to have same length of each ribbon, so we will find the least common multiple of 15, 12 and 20.

Multiples of 15 are: 15, 30, 45, 60, 75, 90,...

Multiples of 12 are: 12, 24, 36, 48, 60, 72, 84,...

Multiples of 20 are: 20, 40, 60, 80,100,...

We can see that 60 is the least common multiple of 15, 12 and 20.

$\text{The smallest number of rolls of blue ribbon}=\frac{60}{15}=4$

Therefore, Mrs. Grey should buy 4 rolls of blue ribbon.

$\text{The smallest number of rolls of silver ribbon}=\frac{60}{12}=5$

Therefore, Mrs. Grey should buy 5 rolls of silver ribbon.

$\text{The smallest number of rolls of yellow ribbon}=\frac{60}{20}=3$

Therefore, Mrs. Grey should buy 3 rolls of yellow ribbon.

three shapes. three areas to find. three areas to add together to find the whole area. gotcha.

Step-by-step explanation:

smaller rectangle
larger rectangle
right triangle

<h2> smaller rectangle: </h2>

length is 7 cm and width is 4 cm, so the area is <u>28 square cm</u>

<h2></h2><h2>larger rectangle:</h2>

width is 4 cm and length is 10 cm, so the area is <u>40 square cm</u>

Because the weird shape's bottom length was 13 cm. There are 3 cm and 7 cm on the top length(s) of the weird shape, next to each other. Looking at the dash lines, when adding 3 cm and 7 cm together, the larger rectangle's length is 10 cm.

<h2>right triangle: </h2>

base is 3 cm and height is 8 cm, so the area is (3x8)/2 = 24/2 = <u>12 square cm</u>

With knowledge from figuring out the larger rectangle's length being 10 cm and the weird shape's bottom length being 13 cm, we know the right triangle's base is 3 cm. (13 cm - 10 cm = 3 cm for the base of the right triangle).

Due to adding 4 cm and 4 cm of weird shape's width, which is also a right triangle's height.

<h2>weird shape's area from adding three shapes' areas: </h2>

28 + 40 + 12

= 80 square cm (ANSWER)

Rewrite the function by completing the square. h(x)= x^{2} +3 x -18 left parenthesis, x, right parenthesis, equals, x, squared,

ludmilkaskok [199]

Answer:

h(x) = (x +1.5)^2 -20.25

Step-by-step explanation:

We assume you want to rearrange h(x)= x^2 +3x -18.

Recognize the coefficient of x is 3. Add and subtract the square of half that. (3/2)^2 = 9/4 = 2.25

h(x) = (x^2 +3x +2.25) -18 -2.25

Now, write the expression in parentheses as a square, simplify the constant.

h(x) = (x +1.5)^2 -20.25 . . . . . . . . vertex form
