<u>Geometry</u>

Volume of a Cone Formula: \displaystyle V = \frac{1}{3} \pi r^2h

  • <em>r</em> is radius
  • <em>h</em> is height

Step-by-step explanation:

<u>Step 1: Define</u>

Radius <em>r</em> = 4

Height <em>h</em> = 21

<u>Step 2: Find Volume</u>

  1. Substitute in variables [Volume of a Cone Formula]:                                      \displaystyle V = \frac{1}{3} \pi (4)^2(21)
  2. Evaluate exponents:                                                                                         \displaystyle V = \frac{1}{3} \pi (16)(21)
  3. Multiply:                                                                                                             \displaystyle V = \frac{16 \pi}{3}(21)
  4. Multiply:                                                                                                             \displaystyle V = 16 \pi \cdot 7
  5. Multiply:                                                                                                             \displaystyle V = 112 \pi

Someone please explain this question PART "b) i" ONLY!!!
Gnom [1K]
<h3>Answer:   (n-1)^2</h3>

This is because we have a list of perfect squares 0,1,4,9,...

We use n-1 in place of n because we're shifting things one spot to the left, since we start at 0 instead of 1.

In other words, if the answer was n^2, then the first term would be 1^2 = 1, the second term would be 2^2 = 4, and so on. But again, we started with 0^2 = 0, so that's why we need the n-1 shift.

You can confirm this is the case by plugging n = 1 into (n-1)^2 and you should find the result is 0^2 = 0. Similarly, if you tried n = 2, you should get 1^2 = 1, and so on. It appears you already wrote the answer when you wrote "Mark Scheme".

All of this only applies to sequence A.

side note: n is some positive whole number.

Why will the value of y for the function y equals 5x + 1 always be greater than that of y equals 4x + 1 with X greater than 1?
klemol [59]
You mean
the linear equations, 5x-y+1=0,4x-y+1=0
the slopes are 5 and 4 respectively.
it is clear that slope of first equation is greater that is it has a steeper graph therefore it Will always be greater than the other for x > 1
the same can be done by calculus; differentiation.

note y=5x+1 is always greater than y=4x+1 for all x>1
