1st, 2nd,& 4th. If the variable is in the root or in the denominator / have a negative power, then it is not a polynomial. The 3rd one has the root of y, so it isnt a polynomial.
Answer:12/1=60/5. 1/2=5/60
Step-by-step explanation:
Just took the test
Answer:
Step-by-step explanation:
The compounding formula for this is
where A(t) is the amount after all the compounding is done, P is the initial investment, r is the interest rate as a decimal, n is the number of times the interest compounds per year, and t is the time in years. For us, our n is 2, since the money compounds every 6 months, and 6 months goes into 1 year 2 times. Our formula then is:
which simplifies a bit to
which simplifies a bit more to

Raise 1.06 to the power of 18 and then multiply the 2 numbers together:
A(t) = 823(2.854339153) so
A(t) = 2349.12
Answer:
B. infinite solutions along a line
Step-by-step explanation:
The matrix is equivalent to the equations ...
x = 2
y = 9
0z = 0 . . . . . . true for any z
This tells you the solutions are ...
(x, y, z) = (2, 9, z)
This defines a line parallel to the z-axis.
There are 10 digits possible for each of the 4 places .
So the number of digits possible is 10^4 = 10,000
