A.) according to the graph, Austin appears to be burning 10 calories per minute. If you look at a perfect point on the graph, which I chose (50,5) and you do x over y or calories per minute, you get a unit rate of 10 calories per minute.

b.) Since you have already found the unit rate in question a, your slope would be 10.

Phantasy [73]

Answer:

Im not 100% sure but I got 1.66667 so therefore I would say about 4:00 maybe? Didn't really understand lmk.

Step-by-step explanation: I added 46, 29, and 25 together which gave me 100 and i put that into minutes which gave me 1.66667 which rounds to 1.70 and so if 60 seconds is 1 hour than 2:00 plus 2 hours is 4. That's what I got out of it.

4vir4ik [10]

Answer:

a. yes

b. no

c. no

d. no

e. yes

Step-by-step explanation:

Here, we want to answer yes or no for each of the numbers

a) Yes

If we compare with the general form

y = mx + b

m

is slope and b is y-intercept

so, 2 is slope and 3 is y intercept; so 3 in y-intercept is (0,3)

b. No

This is the point-slope form we are trying to

get

Evaluating this, we have that

y-3 = 2x - 6

y = 2x-6 + 3

y = 2x-3

c) NO

Just insert the values and check here

-1 = 2(5) + 3

it does not work

d) No

Substitute

-4 = 2(-5) + 3

e) Yes

This is the point-slope form

y + 3 = 2x + 6

y = 2x + 6-3 = 2x + 3

find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
IceJOKER [234]
(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²

Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²

143.92 = R²  → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :

circumference of a circle = 2π.R = 2.π.12 = 75.41 m
