It should be C. Because technically you can’t measure the the temperature when the problem occurs. You can check it later tho, so be careful.

Answer:

C. temperature of the engine when the problem occurs

Explanation:

When you are driving the engine of your car gets very hot, if there is a driving problem of your engine, there is no way of knowing what was the engine temperature at the time the problem happened, because you can not measure the temperature without get burned. For this reason, we can state that engine temperature when the problem occurred is not an important factor in diagnosing an engine driveability problem. However, factors such as the type of gasoline used, the brand of engine oil used, and the list of previous repairs are all very important and may indicate what is happening with your car.

The function f is continuous on the interval (0,16), and f is twice differentiable except at x=5 where the derivatives are undef

Oliga [24]

Using it's definition, it is found that the function f(x) has a point of inflection at:

A. x = 8 only.

<h3>What are the points of inflection of a function?</h3>

The critical points of a function are the <u>values of x</u> for which:

$f^{\prime\prime}(x) = 0$

Additionally, there has to be a change in the sign of $f^{\prime\prime}(x)$

Researching the problem on the internet, it is found that:

For 0 < x < 5, $f^{\prime\prime}(x) > 0$ .

For x = 5, $f^{\prime\prime}(x)$ is undefined.

For 5 < x < 8, $f^{\prime\prime}(x) < 0$ .

For x = 8, $f^{\prime\prime}(x) = 0$ .

For 8 < x < 12, $f^{\prime\prime}(x) > 0$ .

For x = 12, $f^{\prime\prime}(x) = 0$ .

For 12 < x < 16, $f^{\prime\prime}(x) > 0$ .

The two conditions, $f^{\prime\prime}(x) = 0$ and a change in the signal of $f^{\prime\prime}(x)$ are only respected at x = 8, which is the lone inflection point.

<h3>What is exponential equation?</h3>

Exponential equation is the equation in which the exponent or part of exponents used as variables.

$fx = 33 \times (1.3)^x$

where, x is the number of days, given that x = 20

Putting the values in the equation

$f\times 20 = 33 \times (1.3)^2^0 = 6,271 \;days$

Thus, the correct option is C, 6,271.
