What is the equation of the line that passes through the point (2, -2) and has a
slope of -1/2?

Answers

Answer 1

Answer:

Step-by-step explanation:

use the point-slope formula [y-y1 =m(x-x1) ] with the given info

for the point P=(x1,y1) =(2,-2) and the slople m = -1/2

plug those into the formula

y-(-2)= -1/2(x-2)

y+2= -1/2x + 1

y= -1/2x+1 - 2

y = -1/2x - 1

:)  got it?  

these are hard untill you get the idea of the two formulas  

point-slope:         y-y1 = m(x-x1)  and

slope-intercept:   y= mx+b

memorizing those will help a lot

Michael deposits $3000 into an account that pays simple interest at a rate of 2% per year. How much interest will he be paid in the first 6 years?

Answers

Answer:

$3360 in the first 6 years.

Step-by-step Explanation:

To get the answer, you need to do 3000 x 2%. That would get you 60. Then, you multiply 60 x 6 (6 for the 6 years) which would be 360. Finally, you add 360 to 3000 and your answer would be $3360.

Percy buys tomatoes that cost $0.56 per pound. He pays $2.52 for the tomatoes.


Part 1 out of 3

Percy estimates he bought 5 pounds of tomatoes. Is Percy's estimate reasonable? Complete the explanation.


Use compatible numbers to estimate how many pounds of tomatoes he can buy.


{Answer choices: 25, 5, 35} tenths divided by {Answer choices: 5, 25, 10} tenths is __. His estimate {Answer choices: is reasonable, is not reasonable}

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

Answer:

5 3/4 hours

Step-by-step explanation:

They drove 3 1/2 hours then  2 1/4 hours. We need to find the total of these to find how long this part of the trip was

(3 + 1/2) + (2 + 1/4) = 5 + 1/2 + 1/4

For 1/2, we can multiply both the numerator and denominator by 2 to get

1/2 = 2/4

Substituting that in, we get

5 + 2/4 + 1/4

= 5 + 3/4 hours

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.

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.

Answer:400

Step-by-step explanation:

The mean of T is the expected weight of a selected cup filled with liquid

The mean of T is 400

The data on the table is given as:

               Mean    Standard Deviation

Liquid      250g              20g

Cup         150g                10g

Represent Liquid with L, and cup with C

To calculate the mean of T, we make use of the following formula for expected value

E(L + C)

Since L and C are independent random variables, then

[tex]E(L + C) = E(L) + E(C)[/tex]

Where E(L) and E(C) are the mean values of liquids and cups.

The equation becomes

[tex]E(L + C) = 250g + 150g[/tex]

[tex]E(L + C) = 400g[/tex]

Hence, the mean of T is 400

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].

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.
