Answer:

3.14

Step-by-step explanation:

because the area of a circle is pi × r^2, we can just plug in the value of r which is 1 yard

A = pi × (1)^2

A = pi × 1

A = pi or 3.14

Please help me with this question, will give brainliest.
Ugo [173]

Answer:

See below.

Step-by-step explanation:

A difference of squares is a quadratic written in the form a^2-b^2. This form occurs naturally when distributing binomials.

(2x-3)(2x+3)\\4x^2-6x+6x+-\\4x^2 - 9\\(2x)^2 - 3^2

The difference of squares formula is

a^2-b^2 = (a-b)(a+b)

Example:

m^2 - 16y^2=(m-4y)(m+4y)

x^2-36 = (x-6)(x+6)

Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position
julsineya [31]

Answer:

6 ft/min

Step-by-step explanation:

Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)

Therefore,

the rate of feet per minute will be the feet divided by the minutes;

18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min

Therefore the rate is 6 feet per minute.

<u>IF you need an explanation on what average rate implies:</u>

<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>

Hope this helps :)
