Sully finds the average age of his algebra il class is 16.2 years old. suppose exactly one year later, sully has the exact
same students in his precalc class.

a. describe how the mean and the median of the class would change from one year to the next

b. describe how the range and standard deviation would change from one year to the next

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

the answer is 15 to your question

(f+g)(x) = 3^x+10x+4x-2

      =3^x +14x-2

choice b

fo there supposed to be answer choices there
