Use an addition or subtraction formula to find the exact value of the expression, as demonstrated in example 1. tan(105°)
The trick is to get the X all alone on one side. Start by subtracting 2 from both sides. This wqould give you -1/2X+2-2=-x+7-2 or simplified to -1/2x=-x+5. Next, add x to both sides to give you -1/2x+x=-x+5+x. This simplifies to +1/2x=5. Multiplying by 2 on both sides will get rid of the fraction. Therefore 2*1/2x=5*2. This simplifies to your final answer of x=10.
Answer:
The correct answer would be π.
Step-by-step explanation:
When trying to find the circumference, the formula would 2πr. So, the relationship between diameter and circumference is π.
Answer:
C. But be careful. It depends if you have been told what I was having trouble with.
Step-by-step explanation:
The question is a little unclear. If the actual interest is constant for all situations, the answer is C. The more times you compound, the more interest you will accumulate. Banks don't do it that way. It they compound every three months, then they cut the interest rate by a quarter.
So the interest would look like (1 + 0.022/4)*principle. Whoever made the question has to make clear what is going on. My guess is the intended answer is C.
