Answer:
The formula for the nth term of this sequence is: 31 + (n-1)X6
Step-by-step explanation:
This is an arithmetic sequence (ie. each term is the last term with a fixed value added to it).
T1 =31
T2 = 37 = T1 + 6 = 31 + 6
T3 = 43 = T2 + 6 = 31 + 6 + 6 = 31 + 6X2
…
In general, the nth term is 31 + 6(n-1)
<span>a) f(n) is the number of students in your calculus class whose birthday is on the nth day of the year.
f(n) is not invertible because several different days, n, may have the same number of students, f(n). Then for one specific f(n) you cannot determine a unique n.
b) f(x) is the volume in litters of x kilograms of water at 4 degrees celsius.?
f(x) is invertible because each x gives a different f(x), then you can determine unambiguously which f(x) corresponds to each x.

<h2>
The equation for a horizontal plane through the point (−4,0,−3) is z = -3</h2>
<u>Solution-</u>
Let's assume n is the normal vector for the horizontal plane < 0, 0, 1 > .
The co-ordinate of the point is (-4, 0, -3)
The general equation of a plane is -




∴ The equation for a horizontal plane through the point (−4,0,−3) is z= -3
Answer:
5.54 feet.
Step-by-step explanation:
Let h be the height of the pool and r be the radius of the pool.
We have been given that volume of cylindrical pool in Sunny Days Apartment building is 1200 cubic feet.
We have been given that the radius of the pool is 1.5 times its height. We can represent this information in an equation as:


Substituting equation (1) in volume formula we will get,

Substituting the given volume of pool in formula we will get,



Let us divide both sides of our equation by 2.25 pi.

Let us take cube root of both sides of our equation.
![\sqrt[3]{169.7652726}=h](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B169.7652726%7D%3Dh)


Therefore, the height of the pool is approximately 5.54 feet.
