Answer:
A
Step-by-step explanation:
To evaluate f(2), substitute x = 2 into f(x), that is
f(2) = 2(2)² - 5(2) = 2(4) - 10 = 8 - 10 = - 2 → A
Answer:
Square
Step-by-step explanation:
Plot points A (10,-4), B (6,-7), C (3,-3), D (7,0) on the coordinate plane.
Find slopes of the sides:
The slopes of opposite sides are the same, so opposite sides are parallel. The slopes of adjacent sides have product of -1, then adjacent sides are perpendicular.
Find the lengths of all sides:
All four sides are of the same length.
Quadrilateral ABCD is a square (all sides of equal length and perpendicular)
Answer:
1A: 12
Step-by-step explanation:
2A: 16
3A: 21.333
4A: 13
5A: 14
1B: 15
2B: 12
3B:29
4B: 11
5B: 24
Ok so this is a Pythag question...
So the first step would be A squared plus B squared equals C squared
Your A squared would be 12
You do not have B squared value yet
Your C squared Would be 16
So your equation is 12 squared plus B squared equals 16 squared
Simplified that would be 144 plus B squared equals 256
Subtract 144 from both sides and you get 112 equals B squared so do that dividing symbol thing on both sides and you get 10.58 equals c
C= 10.58
