so all those quadratics have their parent y = x², which has the graph of a "bowl".
and depending on the coefficient, the bowl is wider or not.
the larger the coefficient, the narrower the bowl, the smaller the coefficient, the wider the bowl.
well, 1/2 is smaller then 2, thus y = (1/2)x² is wider than y = 2x².
Answer:
SSS
Step-by-step explanation:
Well, the picture says asks why the triangles are congruent but your question asks why they aren't congruent, so I will just assume that you made a typo, and you really meant: "Which rule explains why these triangles are congruent?"
Well, the triangles have two congruent sides, and they have a common shared side that are both congruent (due to reflexive property), so the triangle theorem SSS (Side-Side-Side) proves that the triangles are both congruent.
Answer:
≈119.3
Step-by-step explanation:
The area for circumference is as follows:

The above equations mean the same thing, because the diameter is just 2 times the radius.
Anyhow, we insert this value into the equation...

This rounds to:
≈119.3
Negative 6, negative 8, and positive 1.
(-6)+(-8)=-14+(1)=-13
(-6)*(-8)=48*(1)=48
