Answer:
f (g(x)) = 12x + 8
g(f(x)) = 12x + 48
Step-by-step explanation:
These are composition of functions.
(Unless I am reading your notation wrong) Are the functions multiplying eachother? Is the F actually a lower case f ?
Simply do some substitutions.
f (g(x)) = 2 ( 6x) + 8 = 12x + 8
g (f (x) ) = 6 (2x + 8) = 12x + 48
Answer:
A = 25
Step-by-step explanation:
Base = |-2-(-7)| = |-2+7| = 5
equation of the line that includes the base
x = 6 (because it is parallel to y axis)
the height passes to the point (-4,-4) and must be perpendicular to the base
the equation of the line of the base hasn’t the slope expressed, so the line of the height has a slope equal to 0
so the equation of the line is y= -4
the point (6,-4) is where the two lines intercept and it is the point where the height hit the base
height = |-4-6| = 10
A = (base x height)/2 = (5x10)/2 = 25
Answer:
131.88cm
Step-by-step explanation:
Implement the formula for circumference of a circle:
2×pi(3.14)×r, r= 21cm and pi is given as 3.14. Substitute your given values into the formula above:
2 × 3.14 × 21= 131.88cm to the nearest hundreth
