slope is 1/2 (change in y/change in x) y intercept is 2 (where the line crosses the y axis) so the equation is y=1/2x+2

Answer:

The y-intercept is 2 and the slope is 1/2. So the equation is y = 1/2x + 2

Step-by-step explanation:

The y-intercept is where the line starts on the y-axis. For the slope to the next point on the line you have to move 2 units to the right and 1 unit up. When writing the slope as a fraction, you always put how far you move up or down above how far you move to the right or left.

Find the area of the circle, given the square has an area of 144 cm2 (leave your answer in terms of ).
A)
127 cm?
B)
2471 cm2
C)
3671 cm2
D)
7271 cm2

Answers

C is the answer to this question explanation: Area of square = 144 cm2, which means each side is √144 = 12 cm

Since the circle is inscribed in the square, the diameter is 12, so the radius is 6cm.

Area of circle = πr2 = π * 62 = 36π cm2, which is your answer :)

eric plotted the graph below to show the relationship between the temperature of his city and the number of cups of lemonade he sold daily: part a: describe the relationship between the temperature of the city and the number of cups of lemonade sold part b: describe how you can make the line of the best fit. write the approximate slope and y-intercept of the line of best fit. show your work, including the points that you use to calculate the slope and y-intercept.

Answers

Answer:

part A: the warmer the city temp was the more lemonade that was sold so a hotter day will sell more lemonade

part B: i used points 40,8 and 90,20 and got m= 25/6 then i did y=mx+b

90=25/6(1)+b

90/1=25/6+b

25/6   25/6

and then B= 21.6

Answer:

3. D 4. B hope this helped :)

bro what grade are you in? this is super easy.
the two dots for question 3 represent 40 and 100, and the difference between these is 60.
for question 4 you merely count the dots for day 1; 7, and the dots for day 3; 5, then add these together. this leaves you with 12, which you then multiply by 3, since each dot represents 3 cupcakes. so your answer for 4 is 36.

question 3. 60

Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?

Answers

Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.

-  

Answer:

Theoretical probability is what is expected to happen, where as experimental probability is what happens when you test out that theory. There is a very unlikely chance that a concept in theory would be the same as a concept in action, therefore explaining why these answers are not alike.

What is the length of the hypotenuse?​

Answers

Answer:

The answer is c = 17 feet

Step-by-step explanation:

The formula to find the hypotenuse is a^2 + b^2 = c^2 (a squared plus b squared equals c squared).  

a = 8 feet

b = 15 feet

a^2 = 8 * 8 = 64

b^2 = 15 * 15 = 225

The next step is to add: 64 + 225 = 289

But we need to remember to square root 289 because we squared a and b.

The square root of 289 equals 17

c = 17 feet

What is the inverse of the function f(x) = 2x - 10?

Answers

f(x)=2x-10

y=2x-10

x=2y-10

x+10=2y-10+10 (add both sides by 10)

2y=x+10

2y/2=x+10/2 (divide both sides by 2)

y=1/2x+5

Final Answer: f^-1(x)=1/2x+5
