The area of a circular wave expands across a still pond such that its radius increases by 14 cm each second. Write a formula for
lara31 [8.8K]

Answer:

A = π(14t)²

Step-by-step explanation:

The radius is increasing at the rate of 14 cm per second.

We need to find the formula for the area A of the circle as the function of time t.

Initial area of the circle,

A = πr², where r is the radius of the circle

Area as a function of t will be :

A = π(14t)²

Here, 14t is the radius of the wave.

I don’t know if there is an outlier or not how can you tell
SIZIF [17.4K]
To find an outlier, multiply the IQR by 1.5

172,500 * 1.5 = 258,750

now, u add that to Q3.....545,000 + 258,750 = 803,750....anything above this number is an outlier

now,u subtract that from Q1....372,500 - 258,750 = 113,750....anything below that is an outlier

u have already done this...u have found the higher end and the lower end....so anyting larger then the higher end or lower then the lower end is ur outlier

so in ur data, there is only 1 outlier and that is 933.....130 is not an outlier because it is not less then 113,750.

I need the answer to this question
disa [49]

Answer:

y = 3/4x + 19/2

Step-by-step explanation:

m = 3/4. point (-6,5)

Point slope form:

y-5=3/4(x- -6)

y -5 = 3/4x + 18/4. 18/4 = 9/2

Y = 3/4x + 9/2 + 5. 5 times 2 plus 9 over 2 = 19/2

y = 3/4x + 19/2
