Answer:
C
Step-by-step explanation:
f"(x) < 0, which means the function is concave down at all values of x.
For any such function, within the domain of a ≤ x ≤ b, the secant line S(x) is below the curve of f(x), and the tangent line T(x) is above the curve of f(x).
Here's an example:

Answer: 0.64sec
Step-by-step explanation:
h= -16t2 + t + 6
a= -16 b=1 c= 6
Using the quadratic equation formular
X = -b ± √b2 - 4ac / 2a
X= -1 ± √1^2 - 4(-16)6 / 2(-16)
=-1 ±√1+384 / -32
= -1 ±√385 / -32
Either X = -1 + 19.62 / -32
= 18.62 /-32
=-0.58 sec
Or X = -1-19.62 / -32
= -20.62 / -32
= 0.64sec
Since there is no negative time, therefore our answer is 0.64sec

Step-by-step explanation:
2:3 is only the most simplified ratio, and since the store used 15 liters of paint, 15/3 = 5 liters of paint. That means 5 * 2 = 10 cans of blue paint.
