How many zeros does the function f(x) = 3x12 − 17x8 + 11x4 − 6x + 23 have?
Answer: the third option (12 zeros..).
Use ^ to denote an exponent..
f(x) = 3x^12 - 17x^8 + 11x^4 - 6x + 23..
We know from that fact that the number of zeros (real or complex) in a polynomial is the same as the degree of the polynomial..
The degree is the greatest/highest power of the terms, which in this case is 12 (since 12 is the greatest exponent..)..
The degree is 12, thus it means there are 12 zero's..
Answer: the third option (12 zero's )...
Not sure
te rate is r
for decay, it is
A=P(1-r)^t
r=rate
P=present amount
dunno what b is
but I guess
A=28000(1-0.13)^t
A=28000(0.87)^t
I would guess the decay factor would be 0.87
Answer:
The correct answer is C if the answers are the same as the picture attached.
Answer:
gas = $0.23, electricity = $0.10
Step-by-step explanation:
Answer:
(-4, 3] U (3, 8]
Step-by-step explanation:
The first lines range is (-4,3]
(the round bracket is because the -4 not included ( clear circle) and the square on because the 3 is included in the range ( the filled circle))
second line - range is (3, 8]
So its (-4, 3] U (3, 8]
