Answer:
The correct answer is option b. Sin or csc
Step-by-step explanation:
<u>Trigonometric ratios</u>
Sinθ = Opposite side/Hypotenuse, Cosec = 1/Sinθ
Cosθ = Opposite side/Hypotenuse , Secθ = 1/cosθ
Tan θ = Opposite side/Adjacent side, cotθ = 1/Tan θ
From the figure we can see a right angled triangle RST,
Right angled at R
<u> To find the value of TS</u>
We have m< S=27º and TR=7
Sin S = TR/TS
TS = Sin S * TR
Cosec = 1/Sinθ
Therefore the correct answer is option b
Answer:
Since the least number of digits in the number is 2 decimal places
Round 3.0478 to 2 dp
3.05+4.92=7.97
B is the answer

Answer:
Patricia's account balance after thirteen years is $867.16
Step-by-step explanation:
This problem is on simple interest calculation
we know that the formula for simple interest is given as
A= P(1+rt)
Given that
P= $612.40
r= 3.2%= 0.032
t= 13 years
Applying the formula we have
A= 612.40(1+0.032*13)
A= 612.40(1+0.416)
A= 612.40(1.416)
A= 867.1584
A= $867.16
<span>$27 is one third of $81.
$81 is $54 more than $27.
$81 is three times as much as $27</span>
