1) 1 degree = 1*10^-10 A= 6.9 * 10^-9 nm
Answer:
Rotation then dilation.
Step-by-step explanation:
Dilation changes the size. So the result is a similar not congruent triangle. The other transformations move the figure around on the plane.
<span>a=first term
r=common ratio
n=the term
a(5)=5*3(5-1)
a(5)=5*81
a(5)=405
The answer is B)</span>
The answer is D 1/2
Cos of 60 = 0.5
Which 0.5 as a fraction is 1/2
The probability that the combination starts with 2 is 1/3
<h3>Probability</h3>
Probability is the likelihood or chance that an event will occur.
Probability = expected/total outcome
The total outcome = 3! = 6
The expected outcome if the combination starts with 2 is given as 2! = 2
Pr(the combination starts with 2) = 2/6 = 1/3
Hence the probability that the combination starts with 2 is 1/3
