Always negative when dealing with expontents
16.45 is less than 16.454, Because 16.45 doesnt have a extra # at the end of the #, Add the pretend 0 to 16.45 and compare 0 to 4, And 4 is greater than 0
Answer:
Step-by-step explanation:
because The curve C crosses the x-axis at the origin and at the points A and B => the x coordinates of A and B are the solution of the equation:
x(x + 4)(x - 2) = 0
<=> x = 0
x = -4
x = 2
because the x-coordinates of the points A and B aren't 0 and the x-coordinate
of A is a negative value
=> the x-coordinate of A is -4
the x-coordinate of B is 2
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
