How can u find the slope of a equation
Tomtit [17]

Answer:

It is the rate of change (how far it goes up or how far it goes down)

Step-by-step explanation:

The slope of a line is a measure of how fast it is changing. This can be for a straight line -- where the slope tells you exactly how far up (positive slope) or down (negative slope) a line goes while it goes how far across. Slope can also be used for a line tangent to a curve. Or, it can be for a curved line when doing Calculus, where slope is also known as the "derivative" of a function. Either way, think of slope simply as the "rate of change" of a graph

Example: if you have a slope of 2 your equation would be y=2x+1

You would always do rise over run. rise over run means when you put your slope in a fraction the numerator would always go up or down and the denominator would be run and run means you would go left or right. it all depends on if it is positive or negative.

Hope this helps good luck @(^_^)@

In a certain​ four-engine vintage​ aircraft, now quite​ unreliable, each engine has a 15​% chance of failure on any​ flight, as
Romashka [77]

Answer:

0.0975 or 9.75%

Step-by-step explanation:

Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

P = 0.15*(1-0.35)\\P=0.0975

The probability of exactly one engine failure is 0.0975 or 9.75%

#36 graph in desmos and label points of inflection, critical points, local extremes, absolute extremes, asymptotes, etc
Oksana_A [137]

Question 36.

Given the function:

f(x)=ln(x^2+1)

Let's graph the function.

Let's graph the function using desmos, then label the following:

• 1. Points of inflection

,

• 2. Critical points

,

• 3. Local extremes

• 4. Asymptotes

• The inflection points are the points the function changes concavity.

,

• The local minimum is the point where the minimum value is obtained.

,

• The critical point is the point the function changes direction.

• There is no vertical or horizontal asymptote.

ANSWER:

• The inflection points are the points the function changes concavity.

,

• The local minimum is the point where the minimum value is obtained.

,

• The critical point is the point the function changes direction.

• There is no vertical or horizontal asymptote.
