Answer:
q=-1128/169
Step-by-step explanation:
x²n-14x+q=0 here a=1, b= -14, c=q
let the roots of the equation beα and β
then the sum of the roots= S= α+β= -b/a=-(-14)/1=14
α+β=14 ⇒β=14-α--------(i)
product of the roots=P= αβ= c/a= q/1=q------(ii)
since α-β=6--------(given)----(iiI)
put the values of β from equation i to equation iii
α-14α=6
-13α=6
α=-6/13
put the values of α and β in eq. (ii)
αβ=q=(-6/13)(14-(-6/13)
q=(-6/13)(182+6/13)
q=(-6/13)188/13
q=-1128/169

>>1st one- at X=0 Y=DNE so the function is not continious.
>>2nd one- there is Y value for every X so the function is continious.
>>3rd one- there is Y value for every X so the function is continious.
>>4th one- f(-1)=1 does not equal the limit of f(x).
because the limit as X aprroaches from the left and from ther right is different.
Step-by-step explanation:
when the scale says 1:500000, then that means 1 unit in the map corresponds to 500000 units in reality.
and so, 3.2 cm on the map are
3.2 × 500000 cm in reality.
3.2 × 500000 = 1,600,000 cm = 16,000 m = 16 km
12 years, use the slope of the line of best fit to find the best estimate for the age of the child.
ex: (3,10), (6,20), (9,30), which means the y value of 40 must be 12.
