Elena cycled to school. Find the distance travelled by Elena if her bicycle wheels
rotated 840 times and the radius is 0.25 m.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

sina-sinb

cosb+cosa

tana-tanb

cos0+cos x pi/3

20tan

step-by-step explanation:

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

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

      =3^x +14x-2

choice b
