Answer:
c
........ ......
Step-by-step explanation:
126÷42=3
3×28=84
Answer:
D
Step-by-step explanation:
A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.
B is wrong because the function never even reaches 25 on the interval [-2, -2]
C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.
Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.
Hope that helps. :)
3(4x - 4) + 1/2(8x - 6) + 2x - 3 = -144
12x - 12 + 4x - 3 + 2x - 3 = -144
18x - 18 = -144
18x = -126
x = -126/18
x = -7 Answer

Answer:
C.12
Step-by-step explanation:
Apply the formula for tangent-secant
Let the cord length inside the circle to be y
According to the tangent-secant relation
(3+y)/6 = 6/3
cross multiply
3(3+y)=6*6
9+3y=36
3y=36-9
3y=27
y=27/3
y=9
Distance x = y+3
x=9+3=12
