Answer:

Particulate Matter

Explanation:

Carbon monoxide occurs when there is not enough oxygen

nitrogen oxide occurs in an internal combustion engine with the pressure

particulate matter would increase with a poor chimney

III only

possibly CO

Answer: it’s all three of them.

Explanation: this is for sure the answer as I just took the quiz and got it wrong when I put only carbon monoxide.

Hello, I need help with a calculus FRQ. My teacher has given a hint that this last part has to do with the intermediate value th

lesya [120]

Answer:

Yes, at a time t such that (√2)/2 ≤ t ≤ 2.

Explanation:

To answer the question

Therefore, where the domain of the function is the set of all real numbers x for which f(x) is a real number we have

For Chloe's velocity

$C(t) = t\times e^{4-t^2} \ for \ 0\leq t\leq 2$

Finding the boundaries of the function gives;

$0\times e^{4-0^2} = 0$ and $2\times e^{4-2^2} = 2$

At t = 1, we have $1\times e^{4-1^2} = e^{3} = 20.086$

We find the maximum point as follows;

$\frac{\mathrm{d} \left (t\times e^{4-t^2} \right )}{\mathrm{d} x}=0$

From which we have;

$\frac{\mathrm{} e^{4-t^2} - t\times e^{4-t^2} \times2\times t }{(e^{4-t^2} )^2}=0$

$e^{4-t^2} - t\times e^{4-t^2} \times2\times t }=0$

$e^{4-t^2}(1 - t\times2\times t })=0\\e^{4-t^2}(1 - 2\times t^2 })=0\\$

$e^{4-t^2}=0$ or $(1 - 2\times t^2 })=0$

∴ 1 = 2·t² and from which t = (√2)/2

Hence the function C(x) is decreasing from t = (√2)/2 to t = 2

For Brandon

For 0 ≤ t ≤ 1, 1 ≤ B(t) ≤8 and for 1 < t ≤ 2, 8 < B(t) ≤ 1.5

1 ≤ f(x) ≤ 1.5

Given that the function B(t) is differentiable, therefore, continuous, there exists a point at which the function C(t) and B(t) intersects given that;

For 0 ≤ t ≤ (√2)/2, 0 ≤ C(t) ≤ 23.416 for (√2)/2 < t ≤ 2, 23.416 > C(t) ≥ 2

and for 0 ≤ t ≤ 0 1 ≤ B(t) ≤ 8 and for 1 < t ≤ 2, 8 > B(t) ≥ 1.5

Therefore, the curves intersect at in between (√2)/2 ≤ t ≤ 2.

A clinical psychologist wants to know whether people who have had psychotherapy are more or less likely to have problems in the

Karolina [17]

The independent variable is psychotherapy while the dependent variable is the people.

<h3>The types of variables.</h3>

In an experiment, there are two (2) main types of variables and these include the following:

Dependent variable.

Independent variable.

<h3>What is an independent variable?</h3>

An independent variable can be defined as the variable that is being manipulated by an experimenter or researcher. This ultimately implies that, it is typically considered to be the cause in an experiment and it stands alone because it cannot be changed by any variable being observed or measured.

<h3>What is a dependent variable?</h3>

A dependent variable can be defined as the variable which signifies the effect of an independent variable and it is dependent on other factors because it's the part of an experiment that's being observed or measured.

Based on the information provided about this experiment, we can infer and logically deduce that the independent variable is psychotherapy while the dependent variable is the people.

Brake-fluid condition can be tested visually, using litmus-type test strips and by checking the A. temperature. B. pressure. C.

Ghella [55]

The correct answer is C. viscosity.
You can check the viscosity of the brake-fluid with using a voltmeter. You can see that by using the voltmeter and read on it the volts, the bigger the voltage the bigger the moisture in brake-fluid, thus less viscosity.
