3/8 =0.375
2/5 = 0.4
least to greatest would be
3/8, 2/5, 0.44, 0.5
First, we calculate the amplitude
A = (1/2) (xmax - xmin)
A = (1/2) (8 - (-2)) = 5
Since we're given with the period which is pi, then the coefficient of x is just 1. So, the model is
y = 5 sin x
Answer: 10 dimes
Solve using system of equations.
q=number of quarters and d=number of dimes
.25q+.10d=5.50 because the total of dimes and quarters is $5.50
8+d=q because there are 8 more quarters than dimes
substitute 8+d for q into the first equation to get .25(8+d)+.10d=5.50
then simplify
2+.35d=5.50
.35d=3.50
d=10 he has 10 dimes
If a^2+b^2=c^2 then it's a right triangle
If c^2>a^2+b^2 then it's obtuse
If c^2< a^2+b^2 then it's acute
Answer:
the answer is 4√7
Step-by-step explanation:
Using Pythagoras Thereon
It is 16²+ 4²
= 256+16
= √272
= √16.49
= 4√7
