A: Given that: g={(-2, -9), (4, 9), (5, -6), (8, 4)}h(x)=3x-14

Q: find the equivalent of sec^2theta-1/sec^2theta

A:

Q: = (T-) (प॰,,५) %3D -1 = )7-6 (4-7) 11 Find the fcilowing: 3D3x+8 9={-7,-6),(0, -7),(2,8), (5, 6)3

A: Given : g = {(-7,-6),(0,-7),(2,8),(5,6)} h(x) = 3x + 8   g-1(-7) = ? g(0) = -7 g-1(-7) = 0   h-1(x)…

Q: sec^2 x + tan x = 1

A:

Q: Select all that apply. Correlation cannot be negative cannot be larger than 1 can be negative can…

A: Correlation: Correlation determines the size and direction of the relationship between the two…

Q: Factor  Cos^4 x + 2 cos^2x + 1

A:

Q: sec-1(-2)

A: Given,   sec-1(-2)   Put x =sec-1(-2) Thus x ∈0, π   Now, sec(x) = -2

Sequence and Series

A sequence is defined as a collection of things. Series is defined to sum the things one by one in the sequence.  It was invented by German mathematician Carl Friedrich Gauss.
