Answer:
x = 90° or π/2 rad
Step-by-step explanation:
4+ 2 sin x=14-8 sin x
2 sin x + 8 sin x = 14 - 4
10 sin x = 10
sin x = 1
Using a calculator
x = sin
1
x = 90° or π/2 rad
Answer:
Step-by-step explanation:
Isolate the x. Note the equal sign, what you do to one side, you do to the other.
Subtract 2/4 from both sides
x + 2/4 (-2/4) = 8/4 (-2/4)j
x = 8/4 - 2/4
Simplify
x = (8 - 2)/4
x = 6/4
Simplify. Change the improper fraction into mixed fraction
x = 6/4 = (4/4 + 2/4) = 1 2/4
1 2/4 simplified = 1 1/2
1 1/2 is your answer

There are no given figures. I'll just show what the difference is. Let us assume the following
Principal = 10,000
interest rate = 12%
term = 4 years
Simple Interest = Principal * interest rate * term
S.I = 10,000 * 12% * 4 years
S.I = 4,800
Total value at the end of 4 yrs = 10,000 + 4,800 = 14,800
Compounded Interest. Compounded quarterly.
A = P(1 + r/n)^n*t
A = 10,000 (1 + 12%/4)^4*4
A = 10,000 (1.03)^16
A = 10,000 (1.60)
A = 16,000 value after 4 years.
Answer:
x=65
Step-by-step explanation:
Step 1: Add -3 to both sides.
√x−1+3+−3=11+−3
√x−1=8
Step 2: Solve Square Root.
√x−1=8
x−1=82(Square both sides)
x−1=64
x−1+1=64+1(Add 1 to both sides)
x=65
Check answers. (Plug them in to make sure they work.)
x=65(Works in original equation)
