The graph of f(x) = x6 – 2x4 – 5x2 + 6 is shown below. On a coordinate plane, a graph of a function is in all four quadrants. It

kondaur [170]

Answer:

There are two rational roots for f(x)

Explanation:

We are given a function

f(x) = x^6-2x^4-5x^2+6f(x)=x6−2x4−5x2+6

To find the number of rational roots for f(x).

Let us use remainder theorem that when

f(a) =0, (x-a) is a factor of f(x) or x=a is one solution.

Substitute 1 for x

f(1) = 1-2-5+6=0

Hence x=1 is one solution.

Let us try x=-1

f(-1) = 1-2-5+6 =0

So x =-1 is also a solution and x+1 is a factor

We can write f(x) by trial and error as

f(x) = (x-1)(x+1)(x^2-3)f(x)=(x−1)(x+1)(x2−3)

We find that f(x) (x^2-3)f(x)(x2−3) factor gives two irrational solutions as

±√3.

Hence number of rational roots are 2.

To the heated water 0.5 kg of water at t3 = 20° c is added. what is the final temperature of the water, in kelvin?

Kay [80]

The final temperature of the water after addition to the heated water at 20° C in degree kelvins' is calculated as; 295.23 K

<h3>What is the Final Temperature?</h3>

We are given;

mass of the initial water; m₁ = 2.5 kg

specific heat capacity of water; c = 4189 J/kg.K

initial temperature of water; T₁ = 13.5 ⁰C

final temperature of the water; T₂ = 22.5 ⁰C

mass of the final water; m₂ = 0.5 kg

initial temperature of the final water; T₁,i = 20 ⁰C

If the system is isolated, then we have;

m₁*c*(T_f - T₂) + m₂*c*(T_f - T₁,i) = 0

c will cancel out to give;

[2.5T_f - (2.5*22.5)] + [0.5T_f - (0.5*20)] = 0

2.5T_f - 56.25 + 0.5T_f - 10 = 0

3T_f = 66.25

T_f = 66.25/3

T_f = 22.08°C = 295.23 K

Perform hypothesis testing using the critical value approach brainly.

lord [1]

There are a lot of ways to test for an hypothesis. There are known five steps of a test of hypothesis through the use of the critical value approach. They are;

One has to Specify the Null Hypothesis.
You have to also specify the Alternative Hypothesis.
Then you set the Significance Level.
Calculate the Test Statistic and Corresponding P-Value.
Lastly, Draw a Conclusion.

<h3> The critical value approach? </h3>

This is known as a method that involves the determining of the "likelihood" or "unlikelihood" by knowing if or not the observed test statistic is said to be of a more extreme measure than would be expected if the null hypothesis were true.

It often uses the sample data and then there is an assumption if the null hypothesis is true before one can calculate the value of the test statistic.
