A 38kg child is at the top of a slide that is 2.1m tall. (a) If there is no friction, how fast will they be moving when they reach the bottom of the slide? (b) If they lose 250.0J of energy to sound, heat, and friction, how fast will they be moving when they reach the bottom?

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

the awnser is visionary

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
