Answer:

Finding the Zeros of Polynomial Functions The Rational Zero Theorem helps us to narrow down the list of possible rational zeros for a polynomial function. Once we have done this, we can use synthetic division repeatedly to determine all of the zeros of a polynomial function. Given a polynomial functionuse synthetic division to find its zeros.

Step-by-step explanation:

Answer:

The rational roots theorem is a very useful theorem. It tells you that given a polynomial function with integer or whole number coefficients, a list of possible solutions can be found by listing the factors of the constant, or last term, over the factors of the coefficient of the leading term.

Hope that helps.

Name the property the equation illustrates (ab)3=a(b3)
Anvisha [2.4K]
The answer to this rests on knowing that there are four properties of multiplication (which your teacher will likely expect you to know...):

These are:
1. commutative
2. associative
3. multiplicative identity
4. distributive

I won't define each of these -- they should be in your notes or textbook. Look them up.

In this case, we are multiplying three terms together -- on the left hand side the parentheses mean to multiply a and b first, then multiply that by 3. On the right hand side, we multiply b times 3 first, and then multiply the product by a.

This would be an example of the associative property of multiplication: when three or more factors are multiplied together, the product is the same regardless of how the factors are grouped.

Hope this helps!

Good luck

Find the area of the circle with a radius of 2 cm.
Anna11 [10]

Answer:

a 12.56 cm2

Step-by-step explanation:

area = πr² or I'd

step 1: substitute (plug in) for r which in here is 2

π(2)²

step 2: follow order of operations

(2)²= 4 *π= 12.56

P- parenthesis

E-exponent

MD- multiply and divide from left to right

AS- add and subtract from left to right

A line passes through the points (–5, 2) and (10, –1). Which is the equation of the line?
givi [52]

The correct answer is A) y = -1/5x + 1

To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - -1)/(-5 - 10)

m = 3/-15

m = -1/5

Now that we have the slope, we can use it along with either point in point-slope form to get the equation.

y - y1 = m(x - x1)

y - 2 = -1/5(x + 5)

y - 2 = -1/5x - 1

y = -1/5x + 1
