4 (e)
sin^8 x - cos^8 x
= (sin^4 x + cos^4 x)(sin^4 x - cos^4 x)
= (sin^4 x + cos^4 x)(sin^2 x - cos^2x)(sin^2 x +cos^2 x)
= (sin^4x + cos^4 x)( sin^2 x- cos^2 x)
Sorry I cant do 4 (d).
Step-by-step explanation:
let the unknown number be x
1St step: twice the number is 2(x) =2x
2nd step: 2x -14
3rd step: 2x - 14=28...
Answer: A floating-point number is one where the position of the decimal point can "float" rather than being in a fixed position within a number. floating point is a variable type that is used to store floating-point number values.
Answer:
D
Step-by-step explanation:
To find the y- intercept, let x = 0 in the equation
Given
f(x) = -
- 1, then
f(0) = -
- 1 = -
- 1 ← y- intercept,
(0, -
- 1 ) ← coordinates of y- intercept
