no
Step-by-step explanation:
as 205 is the term greater than the 1st term of AP and the difference is in decreasing order
Answer:
1,2 and 4 are equivalents. 3 is not equivalent
2P-I, mark that one :l
Step-by-step explanation:
1) A quadratic will have no real roots when its discriminant is negative
Dividing by 4,
We have a positive coefficient on k^2 so this parabola is a CUP (concave up positive) so has a minimum at the vertex. If the vertex y value is less than zero, the inequality will be true in the range between the zeros.
That's true for
2) We look for the meet of the line and the parabola:
For two intersections we need a positive discriminant:
That's means two negative or two positive, so
or

<h3>What do you mean by Mean?</h3>
Aside from the mode and median, the mean is one of the measures of central tendency used in statistics. The average of the specified collection of numbers is what is referred to as the mean. It indicates a data set's values are distributed equally. The three most popular methods for determining central tendency are the mean, median, and mode. To find the mean, tally up all the values listed on a datasheet, then divide that total by the total number of values. When all the values are organised in ascending order, the median is the value that falls in the middle of the data. The number in the list that is repeated a maximum number of times is the mode, in contrast.
