Answer:
Given function is decreasing for all x-values , except 4.
Step-by-step explanation:
We are given with a graph of the function and we are asked to find x-values for which function is decreasing.
We will say a function is decreasing If as x increases(from left to right) y decreases(goes down).
The given graph has 2 regions till x=4 and after x=4
Till x=4, if we see the graph from left to right, graph is going down, which means it is decreasing.
After x=4 also, as x goes from left to right, graph is going down, which means it is decreasing after x=4 also.
Hence the given function is decreasing for all x-values except x=4.
Take S(x^2+5)-(x^2)dx from 2 to 4
=S5dx=5x from 2 to 4
=5*4-5*2=20-10=10
If lines through XY and YW form a 90° angle, so that Y is a right angle,
then the product of the slopes of the lines through XY and YW must be -1
let the slopes through X,Y and Y,W be
and
respectively
so
Right answer:
Answer: There are 35 spellers participated in the spelling bee.
Step-by-step explanation:
Since we have given that
Rank of Anish's placement at the highest = 11 th
Rank of Anish's placement at the lowest = 25 th
We need to find the number of spellers participated in the spelling bee.
So, Number of spellers participated in the spelling bee is given by
Highest + Lowest - 1
= 11 + 25 - 1
= 36 - 1
= 35
Hence, there are 35 spellers participated in the spelling bee.
