Answer:
The answer is
<h2>18</h2>
Step-by-step explanation:
a ∆ b = a² + ab + b²
(3 ∆ 2)
a = 3 b = 2
(3 ∆ 2) = 3² +3(2) + 2²
= 9 + 5 + 4
= 9 + 9
= 18
Hope this helps you
<span>For problem 8:
sin A/a sinB/b = sinC/c
so sin50/15 = sinB/12
0.766/15 =sinB/12
0.051066 = sin B/12
sin B = 0.6128
B = 37.79 degrees
sum of angles must equal 180 deg therefore C = 180-50-37.79 = 92.21 degrees and .766/15 = sin92.21/c
.051066= 0.99925/c
c = .99925/0.051066 = 19.567
Problems 9 and 10 can also be done with the same method as problem 8.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
whattt do I have to do translate what???
Answer:
In 11 years
Step-by-step explanation:
To calculate the number of years it will take to depreciate to that value, we use the equation below; The amount after t years, with initial amount I at percentage of depreciation d can be represented as follows;
A = I( 1 - d)^t
In the question Using our definition, A = $8,500, I = $22,000, d = 8.5% = 8.5/100 = 0.085 and t = ?
Let’s plug these values;
8,500 = 22,000(1 - 0.085)^t
8,500 = 22,000(0.915)^t
divide both side by 22,000
8,500/22,000 = (0.915)^t
0.3864 = (0.915)^t
Taking the logarithm of both sides
log 0.3864 = log(0.915)^t
log 0.3864 = tlog 0.915
t = log 0.3864/log 0.915
t = 10.7 approximately 11 years
