Answer:
C. 12
Step-by-step explanation:
Average rate of change = 
Where,
a = 1, f(a) = 3
b = 3, f(b) = 27
Average rate of change = 
Average rate of change = 
Average rate of change for the interval from x = 1 to x = 3 is 12
Answer:
3√7
Step-by-step explanation:
9²+B²=12²
simplify
81+B²=144
minus the 81
B²= 63
Answer:
The distance is 8 cm
Step-by-step explanation:
The chord and the diameter form one leg and the hypotenuse of a right triangle. The other leg, BD, has length ...
BD² +AB² = AD²
BD² = AD² -AB² = 34² -30² = 256
BD = √256 = 16
The segment from the center of the circle to the midpoint of the chord is the midline of triangle ABD, so is half the length of BD.
distance from AB to the center = 16/2 = 8 . . . cm
Answer:
x = -1
Step-by-step explanation:
1/2 = 2/4
____________________________________________________________
1/4x + 3/4 = 2/4
<u> -3/4 -3/4</u>
1/4x = -1/4
divide by -1/4
x = -1
