Answer:D
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8.5%/100 = 0.085 per year
putting time into years for simplicity
6 months ÷ 12 months/year = 0.5 years
then, solving our equation
I = 10000 × 0.085 × 0.5 = 425
I = $ 425.00
on a principal of $ 10,000.00
at a rate of 8.5% per year
for 0.5 years (6 months) is $ 425.00
The required value of x is 4.

Answer:
tangent theta = 12/5,
cosecant theta = 13/12
secant theta = 13/5
Cotangent theta = 5/12
Step-by-step explanation:
Given sine theta= 12/13, cosine theta= 5/13.
According to SOH CAH TOA
Sintheta = Opposite/Hypotenuse = 12/13
Cosine theta = Adjacent/Hypotenuse = 5/13
Opposite = 12, Adjacent = 5, Hypotenuse = 13
Tan theta = Opposite/Adjacent = 12/5.
cosecant theta = 1/sintheta = 1/{12/13}
cosecant theta = 13/12
secant theta = 1/cos theta = 1/{5/13}
Secant theta = 13/5.
Cotangent theta = 1/tan theta = 1/{12/5} = 5/12
