First question: A, Second question: B

Step-by-step explanation:

0.5= 1/2

0.25= 1/4

0.4= 2/5

Now, insert these numbers, as fractions, back into the equation:

\frac{1}{4}- \frac{1}{2}+ \frac{1}{2}- \frac{1}{4}+ \frac{3}{5}+ \frac{2}{5}

Following PEMDAS you will get 1 as your answer.

A rate of 4 centimeters per second is equal to how many meters per hour?
vampirchik [111]
So, let's start with the basics.
One meter is 100 centimeters. Seeing that we have 60 seconds in a minute, and 60 minutes in an hour. The formula would look like this.
(60*60)4
3600*4 = 14400 centimeters
So then we divide it by 100, and
144 meters

What is the multiplicity of each of the roots of the graph of f(x)=−-x^3+2x^2+3x?
DerKrebs [107]

Answer:

A. -1, multiplicity 1; 0, multiplicity 1; 3, multiplicity 1.

Step-by-step explanation:

Let f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x, to determine its roots and multiplicities we proceed to factorize the polynomial:

1) -x^{3}+2\cdot x^{2} +3\cdot x Given

2) x\cdot (-x^{2}+2\cdot x + 3) Distributive property

3) x\cdot (x-3)\cdot (x+1) Quadratic formula/Result

The roots and multiplicities of f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x are:

<em>0 (multiplicity 1)</em>

<em>3 (multiplicity 1)</em>

<em>-1 (multiplicity 1)</em>

Therefore, the correct answer is A.
