Find the GCF of the polynomial 3a3b3 + 9a2b + a2

jasenka [17]

Answer:

a^2.

Step-by-step explanation:

The greatest common factor is a^2. It cannot be 3ab or 3a^2b because b is not present in the last term (a^2). Similarly there is no 3 or multiple of 3 in a^2.

What’s the derivative of the function: A) f(x)= 1/x , in point 2. B) f(x)= 5x^2 , in point 3

bija089 [108]

Using the power rule, the derivatives are given as follows:

a) $f^{\prime}(2) = -\frac{1}{4}$ .

b) $f^{\prime}(3) = 30$ .

<h3>What is the power rule for a derivative?</h3>

Suppose we have a power function given by:

$f(x) = x^n$

The derivative of the function is given by:

$f^{\prime}(x) = n \times x^{n-1}$

Item a:

The function is:

$f(x) = \frac{1}{x} = x^{-1}$

Then the derivative is:

$f^{\prime}(x) = -x^{-2} = -\frac{1}{x^2}$

When x = 2, the derivative is:

$f^{\prime}(2) = -\frac{1}{4}$

Item b:

The function is:

$f(x) = 5x^2$

Then the derivative is:

$f^{\prime}(x) = 10x$

When x = 3, the derivative is:

$f^{\prime}(3) = 30$

To see if the slopes are the same, write an equation setting the two fractions equal to each other. Is this equation true? Why o

RoseWind [281]

Answer:

$Slope(EA)=Slope(AC)=\dfrac{2}{3}$ ....Equation is True

Slopes are EQUAL for

SAME Line

Hence, E-A-C is the same Line.

Step-by-step explanation:

Given:

The three points for the given line are

point E( x₁ , y₁) ≡ ( -6 ,-4)

point A( x₂ , y₂) ≡ (0 , 0) .....Origin

point C(x₃ , y₃ ) ≡ (3 , 2)

To Find:

Slope EA = ?

Slope AC = ?

Solution:

For Two point Slope is given as

$Slope=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Substituting the values we get

$Slope(EA)=\dfrac{0--4}{0--6}=\dfrac{4}{6}=\dfrac{2}{3}$

Similarly For AC we have,

$Slope(AC)=\dfrac{2-0}{3-0}=\dfrac{2}{3}$

Therefore,

$Slope(EA)=Slope(AC)$ ....Equation is True

Slopes are EQUAL for

Line is Parallel
SAME Line

Hence, E-A-C is the same Line.
