Cos x = -12/13
sin x = -sqrt(13^2 - 12^2) / 13 = -5/13
tan x = 5/12
tan x/2 = (1 - cos x) / sin x = 1 - (-12/13) / -5/13 = 25/13 * -13/5 = -5
2sin^2 x/2 = 1 - cos x = 1 - (-12/13) = 25/13
sin^2 x/2 = 25/13 / 2 = 25/26
sin x/2 = 5/√26
sin x/2 / cos x/2 = tan x/2
cos x/2 = sin x/2 / tan x/2 = 5/√26 / -5 = -1/√26
sin x/2 = 5/√26
cos x/2 = -1/√26
tan x/2 = -5

Answer:
1. quadratic
2. quadratic
3. linear
4. quadratic
Step-by-step explanation:
In the picture attached, the scatter plots are shown.
The differences between these correlations are:
- linear
: makes a straight line
- quadratic: makes a ∩ or ∪
- exponential: rises or falls quickly in one direction
In plot 1, 2 and 4, we can see that y-values decrease at first and then they increase. This is a feature of quadratic correlation
In plot 3, we can see that y-values increase uniformly as x-values increase.This is a feature of linear correlation
Answer:
384 Square Inches
Step-by-step explanation:
Given a square pyramid with base side edge and slant height

In the given pyramid:
- Slant Height=20 inches
- Base Edge = 8 Inches
Therefore:
Area of Base, A =8 X 8 =64 Square Inches
Perimeter of base, p =4 X 8 =32 Inches

I drew 20 tiles and divided them into 4 groups of 5
