Step-by-step explanation:
<u>Event A - spinning violet or yellow</u>
Assuming that the spinner has 4 different colors (red, orange, violet and yellow) - see attachment.
<u>Event B - rolling an even number</u>
Assuming the number cube has 6 sides numbered 1, 2, 3, 4, 5 and 6. Therefore, the even numbers are 2, 4 and 6.
Events A and B are <u>independent events</u> as the outcome of one event does not affect the outcome of the other event.
For independent events A and B:
To find P(A and B), substitute the found values of P(A) and P(B):
Answer:
y = 2
y = 6
Step-by-step explanation:
The first thing to do is to find the turning point of the function. For this, derive and equal zero to expression
=
x = 0 and x = -2
We have 2 inflection points.
Then we have 2 tangent lines:
At the point (0, 2)
Since it is a point of inflection, then the slope of this line is 0. Therefore the tangent line is:
y = 2.
At the point (-2, 6).
The slope of this line is 0.
The equation of the tangent line to the function is:
y = 6
