Answer:
is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Step-by-step explanation:
Given the function
As the highest power of the x-variable is 3 with the leading coefficients of 1.
- So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.
solving to get the zeros
∵ 
as
so
Using the zero factor principle
if 
Therefore, the zeros of the function are:
is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.
Therefore, the last option is true.
Answer:
8 weeks
Step-by-step explanation:
48 is 75%
x is 100%
48×100=4800
75x=4800
x=4800:75
x=64
64-48=16
16:2=8
Answer is 8 weeks
Answer:
Angles on a straight line add up to 180°
a = 180° - 29°
a = 151°
Answer:
163200m
Step-by-step explanation:
since there is two 17's you qould need to multiply 17 x 2 and then u multiply it times 15 then times 16 but there is two 16's so u multiple that then 10 and that should get you your answer
