What are the zeros of the polynomial function f(x) = (x – 6)(x – 2)(x + 7)?

1 answer:

8 0

The given polynomial is in factored form. So in order to find the zeros of the polynomial, set each factor equal to zero and find the value of x. All such values of x will be the zeroes of the polynomial.

So,
x - 6 = 0
⇒ x = 6

x - 2 = 0
⇒ x = 2

x + 7 =0
⇒ x = -7

Thus the zeros of the given function are x = 6, x = 2 and x = -7

In what quadrant will θ terminate, if sin θ is positive and sec θ is negative?

kow [346]

Sin x is possitive in two quadrants :

quadrant I and quadrant II

in quadrant I, cos x is positive

in quadrant II , cos x is negative

so i think the answer is : quadrant II

hope this helps

Which of the following represents the value of the missing side?

igomit [66]

Answer:

The value of the missing side is $x=2\ units$

Step-by-step explanation:

In this problem i assume that the length side x is tangent to the circle

the length side x is perpendicular to the radius

Applying the Pythagoras Theorem in the right triangle

we have that

$(1.5+1)^{2}=1.5^{2}+x^{2}$

Solve for x

$(2.5)^{2}=1.5^{2}+x^{2}$

$x^{2}=2.5^{2}-1.5^{2}$

$x^{2}=4$

$x=2\ units$

Tamara says that raising the number i to any integer power results in either -1 or 1 as the result, since i^2 = -1. Do you agree

Roman55 [17]

I agree only if you have even powers -- even negative ones.

1/i^2 = 1/-1 = - 1
i^0 also gives 1 So far no problem.

It is when you consider the odd numbers that you don't get 1 or -1
You get either -i or i
i^(4n + 1) = i
i^(4n - 1) = -i
