Its d. i took the k12 test.

d. The temperature steadily decreases before it levels off briefly. Then the temperature steadily decreases at a slower rate for the same amount of time as it decreased initially. After reaching its lowest temperature of the night, the temperature begins to steadily increase. When the temperature gets close to the same temperature it started at, the temperature levels off and remains the same.

For the polynomial function ƒ(x) = x4 −25x2, find the zeros. Then determine the multiplicity at each zero and state whether the

AfilCa [17]

<u>ANSWER</u>

The zeros are $x=-5,x=0,x=5$

EXPLANATION

Given;

$f(x)=x^4-25x^2$ .

We can rewrite the function as

$f(x)=x^2(x^2-25)$

$\Rightarrow f(x)=x^2(x^2-5^2)$

$\Rightarrow f(x)=x^2(x-5)(x+5)$

The zeros are found by equating the function to zero.

$\Rightarrow x^2(x-5)(x+5)=0$

$\Rightarrow (x-5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=5$

Or

$\Rightarrow (x+5)=0$

The multiplicity is 1, since it is odd the graph crosses at this intercept. which is $x=-5$

Or

$\Rightarrow x^2=0$

This last root has a multiplicity of 2.

That is

$x=0$ repeats two times.

Since the multiplicity is even, the graph touches the x-axis at the point $x=0$ .

See graph.

What is the quotient StartFraction 2 m Superscript 9 Baseline n Superscript 4 Baseline Over Negative 4 m Superscript negative 3

Marina CMI [18]

Answer:

$-\frac{m^{12}n^{6}}{2}$

Step-by-step explanation:

We want to find the quotient of $\frac{2m^9n^4}{-4m^{-3}n^{-2}}$

We apply the quotient rule of indices to simplify the given exponential expression.

$\frac{a^m}{a^n}=a^{m-n}$

This implies that:

$\frac{2m^9n^4}{-4m^{-3}n^{-2}}=-\frac{1}{2}m^{9--3}n^{4--2}$

We simplify exponents to get:

$\frac{2m^9n^4}{-4m^{-3}n^{-2}}=-\frac{1}{2}m^{12}n^{6}$

Or

$\frac{2m^9n^4}{-4m^{-3}n^{-2}}=-\frac{m^{12}n^{6}}{2}$

Therefore the correct choice is $-\frac{m^{12}n^{6}}{2}$
