Answer:
52.12
Step-by-step explanation
PEMDAS
Adding comes before subtracting
10+51=61
10+51 41=51.51
61-51.51=-52.12
Answer:
6, 12, 24, 48, 96, 192
Step-by-step explanation:
The first term a1 = 6 and the common ratio is 2.
So it is 6, 6*2, 6*2^2 ....
The third answer option is correct. sqrt(x) = x^(1/2). So sqrt(121) = 121^(1/2).
Tangent = opposite / adjacent
In the diagram:
TQ is the short leg or the opposite
QR is the long leg or the adjacent
TR is the hypotenuse. TS is part of the hypotenuse.
Tan(QTR) = TQ / QR
TS = 1 ; TQ = TS so, TQ = 1
Tan(QTR) = 1/QR
I think the answer is C.RQ
