B is true because 0-(-x) = 0 + x = x
The answer is: " 1024π units² " ; or; " 3215.36 units² " .
______________________________________________________
A = π * r² ;
A = π * 32² = 1024 π units² ;
or, using "3.14" for "π" ;
1024 * π = 1024 * (3.14) = 3215.36 units² .

Answer:
y = 6x - 4
Step-by-step explanation:
slope (m) is 6
y intercept (b) is -4
plug values into y = mx + b:
y = 6x - 4
Answer:
f ( - 2 ) = - 12
Step-by-step explanation:
f ( - 2 ) = - 3 ( -2 )^2
then you do the exponent first so
- 3 ( 4 )
now you multpily the - 3 and 4
you get - 12
Answer:
y = 3x+4
Step-by-step explanation:
Use the coordinates of the points to find the slope of the line passing through them.
slope = Δy/Δx = (10-4)/(2-0) = 6/2 = 3
Point-slope equation for line of slope 3 that passes through (0,4):
y-4 = 3(x-0)
Slope-intercept form of the equation:
y = 3x+4
