Step-by-step explanation:
f(-1)=3×(-1)²-4×(-1)
=3×1-4×(-1)
=3+4
=7
hope it helps.
I think it is 17 but i’m not sure i’m not the best at math
Answer:
16.9 units
Step-by-step explanation:
Sometimes the easiest way to work these problems is to get a little help from technology. The GeoGebra program/app can tell you the length of a "polyline", but it takes an extra segment to complete the perimeter. It shows the perimeter to be ...
14.87 + 2 = 16.87 ≈ 16.9 . . . units
_____
The distance formula can be used to find the lengths of individual segments. It tells you ...
d = √((Δx)² +(Δy)²)
where Δx and Δy are the differences between x- and y-coordinates of the segment end points.
If the segments are labeled A, B, C, D, E in order, the distances are ...
AB = √(5²+1²) = √26 ≈ 5.099
BC = √(1²+3²) = √10 ≈ 3.162
CD = Δx = 3
DE = √(3²+2²) = √13 ≈ 3.606
EA = Δy = 2
Then the perimeter is ...
P = AB +BC +CD +DE +EA = 5.099 +3.162 +3 +3.606 +2 = 16.867
P ≈ 16.9

I am pretty sur it is 3
Step-by-step explanation:
Answer:
<em>∠B is the largest interior angle of the triangle, and AC is the</em><em> largest</em><em> side.</em>
Step-by-step explanation:
Relationship of sides to interior angles in a triangle-
- The shortest side of a triangle is always opposite to the smallest interior angle.
- The longest side of a triangle is always opposite to the largest interior angle.
So converse of the second property is the side opposite to the largest interior angle is always the largest side.
As ∠B is the largest interior angle of the triangle, so its opposite side which is AC will be the largest side.
