Please help with this question

A

Step-by-step explanation:

When the temperature has a negativ sign on it, it is below zero

When the temperature is a natural number, it is above zero

above zero

Step-by-step explanation:

Because if it was below zero there would be a negative Infront of the number so show it’s below zero but there’s not, so I’m pretty sure it would be above zero. I hope this helps

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
