Answer: 16 in
Explanation:
PQ/QR = PT/TS
PQ/4 = 12/3
PQ x 3 = 12 x 4 (cross multiply)
PQ x 3 = 48
PQ = 48/3
PQ = 16
<span>n = n0(1 - 0.08)^t
= n0(0.92)^t
Putting n = n0 / 2:
1 / 2 = 0.92^t
t = log(1 / 2) / log(0.92)
= 8.31 yr.</span><span>

Answer:
2/4 = 1/2
Step-by-step explanation:
Firstly expand cos(x - 30)....which is..
[cos x.cos 30 + sin x.sin 30]
If sin x = -1/2...then cos x = square root of 3/2
Then substitute the values into the expansion above....which...,
[(square root of 3/2)(square root of 3/2) + (-1/2)(1/2) ]
; 3/4 - 1/4 = 2/4
;Ans = 2/4 = 1/2
Answer:
3x^2 - 13x - 1
Step-by-step explanation:
6x^2 - 5x (i think thats what you meant) + 3 - 3x^2 + 8x - 4
= 3x^2 - 13x - 1

How to find inverse of a matrix ?
Only square matrices with an equal number of rows and columns, such as 2 *2, 3* 3, etc., allow us to find the inverse of the matrix. The adjoint of the provided matrix is divided by the determinant of the given matrix to produce the inverse matrix, to put it simply.
|A|=-5(4-3)+4(4-3)-5(4-4)
|A|=-5+4
|A|=-1
