Step-by-step explanation:
N is 3 bc #of terms minus 1
Exponents go from 3>2>x>none
Can be factored using binomial theorem
B.
This is because perpendicular lines have opposite and flipped slopes.

Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Functions can be used to model real life situations.
The hose is 3.2 feet above the ground, at a horizontal distance of 4 fee
The function is given as:

At a horizontal distance of 4 feet, the value of x is 4
i.e. 
Substitute 4 for x in f(x).
So, we have:

Evaluate the exponent

Open both brackets

Add -4.8 and 8

Hence, the hose is 3.2 feet above the ground

Answer:
no
Step-by-step explanation:
An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...
The differences are different, not common, so this is NOT an arithmetic sequence.
