Find parametric equations which describe each curve. No particular orientation is required.

a. The line containing the points (1, 2) and (-3,8).
b. The circle with radius 3 and center (4,1).

Answers

Answer:

The equation of the line is [tex](x(t),y(t))=(1-4t,2+6t)[/tex] and the equation of the circle is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

Step-by-step explanation:

(a) Given: The given points are [tex](1,2)[/tex] and [tex](-3,8)[/tex].

To find: The parametric equation of line containing points [tex](1,2)[/tex] and [tex](-3,8)[/tex].

We know that the parametric equation of line containing [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is given by [tex](x(t),y(t))=(x_{1}+(x_{2}-x_{1})t,y_{1}+(y_{2}-y_{1})t)[/tex] where [tex]t[/tex]∈[tex][0,1][/tex].

Now, [tex]x(t)=1+(-3-1)t[/tex]

i.e, [tex]x(t)=1-4t[/tex]

And, [tex]y(t)=2+(8-2)t[/tex]

i.e, [tex]y(t)=2+6t[/tex]

Hence, the required parametric equation of the line is [tex](x(t),y(t))=(1-4t,2+6t)[/tex].

(b) Given: The radius of circle is 3 and centre is [tex](4,1)[/tex].

To find: The parametric equation of circle with radius 3 and centre [tex](4,1)[/tex].

We know that parametric equation of circle with radius [tex]r[/tex] and centre [tex](h,k)[/tex] is given by [tex]F(t)= (x(t),y(t))[/tex] where [tex]x(t)=rcos(t)+h[/tex] and [tex]y(t)=rsin(t)+k[/tex].

Now, [tex]x(t)=3cos(t)+4[/tex]

[tex]y(t)=3sin(t)+1[/tex]

So, the parametric equation of circle having radius 3 and centre [tex](h,k)[/tex] is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

Hence, the required equation of the circle is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

What is the perimeter of polygon LMNPQ

Answers

Answer: c for maps

Step-by-step explanation:

17.66 units is the perimeter of the polygon.

What is Perimeter?

The perimeter of a two-dimensional form is the space surrounding it. It represents the total length of the shape's sides. The units used to measure the sides of the form, such as meters, centimeters, inches, or feet, determine the units used to measure the perimeter.

To find the perimeter of the polygon LMNPQ, we need to add up the lengths of all the sides.

The distance formula for finding the distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y-2 - y-1)^2)[/tex]

Using this formula, we can find the lengths of each side of the polygon:

[tex]LM = \sqrt{(2 - 4)^2 + (4 - 2)^2} = \sqrt{8}\\MN = \sqrt{(5 - 2)^2 + (8 - 4)^2} = \sqrt{25}\\NP = \sqrt{(8 - 5)^2 + (4 - 8)^2}= \sqrt{25}\\PQ = \sqrt{(6 - 8)^2 + (2 - 4)^2} = \sqrt{8}\\QL = \sqrt{(4 - 6)^2 + (2 - 2)^2} = 2[/tex]

Therefore, the perimeter of the polygon LMNPQ is:

Perimeter = LM + MN + NP + PQ + QL

= √8 + √25 + √25 + √8 + 2

≈ 2.83 + 5 + 5 + 2.83 + 2

≈ 17.66

So, the perimeter of the polygon LMNPQ is approximately 17.66 units.

if we just passed a sign which says that harrison is 25 miles away and turkey is 40 miles ahead, how far will we have to go to be halfway between turkey and harriso

Answers

Answer:

You will need to go 7.5 miles to be halfway between Harrison and Turkey

Step-by-step explanation:

If you see a sign saying that Harrison is 25 miles away and that Turkey is 40 miles ahead, then the distance from Harrison to Turkey must be 40 miles - 25 miles = 15 miles.

If you drive up to be halfway between Harrison and Turkey, then you need to travel 15/2 = 7.5 miles.

You will need to go 7.5 miles to be halfway between Harrison and Turkey

Compute the mean of the following population values:

6, 3, 5, 7, 6.

Answers

Answer:

The mean (average) is 5.4 or 5 if you're rounding.

Step-by-step explanation:

Mean is the average of all of the numbers.

Add them up: 6+3+5+7+6 = 27

Divide 27 by the amount of numbers you have(5): 27/5

Solve: 5.4

The mean of the given values 6, 3, 5, 7, and 6 will be 5.4.

What is mean?

mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.

Mean = sum of data / Number of data

For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be

( 40 + 45+ 44 + 46 + 48) /5 = 44.6.

Given the data set;

6, 3, 5, 7, 6

Mean = (sum of data) / (number of data)

Mean = (6 + 3 +  5 + 7 + 6)/5

Mean = 27/5

Mean = 5.4

Hence the mean will be 5.4.

Answers

Answer:

1) We know that tomatoes cost 56c per the pound, and he estimates that he bought 5 pounds of tomatoes. If we multiply 5 by 0.56 we get 2.8, which means that if he purchased 5 pounds of tomatoes, he would have spent only 20c more than he did, which is pretty close. So yes, his estimate is reasonable

2) Well, i dont hav any clear amount of money he can spend so, just remember, if you have 3 pounds per say, you multiply 3 by 0.56. And then you can find your answer
