Answer:
b=√3
a=2
Step-by-step explanation:
Since you are given one side and an angle, you can immediately think of using cos, sin, and tan
When solving for b, you would set up your equation with tan30=1/b since tangent is opposite/adjacent
Next for a, you would solve for sin30=1/a since sine is opposite/hypotenuse
Hope this helps! :)
Answer:
WHAT
?????????????????????
Step-by-step explanation:
The answer to the first one would be B. The formula for exponential decay with the filled in values are as follows: 25000(.85)^5 Just plug it into a calculator.
The answer to the second question would also be B. The easiest way to get this answer is to find the slope, or how much the y is changing per change of one in x. In this case you can subtract to find it increases by 3 each time. Subtract three from the y value at one to get the y value at 0 or the y intercept
You need to do this LCM(least common multiples)
6,12,18,24,30,36
9,18,27,36,45,54
18 is your answer.
