The correct answer for this problem is A.
Answer: 17/30
Step-by-step explanation:
From the question, Elke lives 1/10 mile from school while Haresh lives 2/3 mile from school.
The closer to school Elke is than Haresh will be:
= 2/3 - 1/10
We can change the fractions to have thesame denominator which will be:
= 2/3 - 1/10
= 20/30 - 3/30
= 17/30
The distance between them is 17/30 miles
Answer:
B. -√13/4
Step-by-step explanation:
cos 0 = -√3/4 => x=-√3 , h=4
tan 0 > 0
y should be on quadrant III
y= √4²-3= √16-3=√13 => -√13
so, sin 0 = y/h = -√13/4

Answer:
The answer is given below
Step-by-step explanation:
A number is said to be a zero of a polynomial if when the number is substituted into the function the result is zero. That is if a is a zero of polynomial f(x), therefore f(a) = 0.
Since P(−1)=0 P(0)=1 P(2+√3)=0, therefore -1 and 2+√3 are zeros of the polynomial.
Gary is right because there are 2 known zeros of P(x) which are −1 and 2+√3. Also 2 - √3 is also a root. From irrational root theorem, irrational roots are in conjugate pairs i.e. if a+√b is a root, a-√b is also a root.
Heather is not correct because if P(0) = 1, it means that 0 is not a root. It does not mean that 1 is a zero of P(x)
Irene is correct. since P(−1) and P(2+3–√) equal 0, 2 zeros of P(x) are −1 and 2+√3. They may be other zeros of P(x), but there isn't enough information to determine any other zeros of P(x)
