We need an angle measure we have to use an inverse trig ratio, sin^-1, cos^-1, or tan^-1.
Setting up the right triangle we have the opposite and adjacent so we use tan.
tan angle = 28/32
tan^-1 (28/32) = 41 degrees
It is not a rational number it is irrational because the decimal doesn't terminate.
Answer:
a) The equation has the greatest slope.
Step-by-step explanation:
The table has the values as shown below;
x y
1 3
2 6
3 9
The gradient of the line can be found as;
m=Δy/Δx
m= 9-3 /3-1
m= 6/2
m₁= 3
The equation of the other line is : y=4x
The gradient is , m₂ = 4
The presentation with the greatest slope is the equation that has a slope of 4.
Answer:
Option (a) is correct.
is a perfect cube.
Step-by-step explanation:
Given : Some Monomial
We have to choose out of given monomial that is a perfect cube.
Perfect cubes are numbers that can be written as 
So, consider , we know 1 can be written as 
Thus, can be written as 
Thus, Option (a) is correct.
