Answer: -1
Step-by-step explanation:
4 year college Tuition: $28,800.00
Money Saved since Sarah was born: $21,600.00
So, no, her family did not save enough for college.
Therefore, the decimal equivalent to the expression 
is 50.02
The given expression is:
Note that 
The expression therefore becomes:
(5 x 10) + (2 x 0.01)
50 + 0.02
= 50.02
Therefore, the decimal equivalent to the expression is 50.02

The answer is 33 meters
use the Pythagorean theorem
56^2+x^2=65^2
3136+x^2=4225
x^2=1089
x=33
Answer: our function is:
f(x) = A*sin(2*pi*270s*x)
Step-by-step explanation:
We have that the frequency of a given engine is 270 hz, it starts at 0, so we may represent this with a sin function (because sin(0) = 0)
Then we could use the function
f(x) = A*sin(c*x)
A is the maximum intensity of the hum, and c depends on te frequency, we know that the period of a sin function is 2pi, then:
f = 270/s
T = 1/270s
c*1/270s = 2pi
c = 2*pi*270s
Then our function is:
f(x) = A*sin(2*pi*270s*x)
