Answer:
I believe Henrey is wrong
Step-by-step explanation:
because the roots of the quadratic function are
<em>"</em><em>(</em><em>x</em><em>=</em><em> </em><em>3</em><em>/</em><em>4</em><em>,</em><em> </em><em>-</em><em>2</em><em>)</em><em>.</em><em>"</em>
Answer:
this probability is 0.68
Step-by-step explanation:
the probability she buys fruit but not a CD is
0.6 × (1 - 0.2) = 0.48
the probability she buys a CD by not fruit is
0.2 × (1 - 0.6) = 0.08
the probability that she buys both is
0.6 × 0.2 = 0.12
the probability that she buys fruit or a CD or both is adding all 3 probabilities :
0.48 + 0.08 + 0.12 = 0.68
Distance - how far it's travelled.
displacement - how far it is from its starting point in a given direction.
distance = 2.5km
displacement = 2.5km east
<h3>Answer:</h3>
... x = 2y^7 -13y^8 -3
<h3>Explanation:</h3>
An inverse relation is one with the independent and dependent variables interchanged.
Having made that interchange (swapping positions of x and y in the equation), you basically cannot solve for y. (There is no formula for the solution of an 8th-degree polynomial.) In any event, this inverse relation is <em>not a function</em>, as there are multiple values of y that correspond to the same value of x.

<em>Comment on inverse functions</em>
A function and its inverse are mirror images of each other across the line y=x. This can be seen in the attached graph.
