3t^2+17t-56 is the answer
Answer:
Option C
Step-by-step explanation:
We will analyze the figure and note down the properties given in the figure,
1). LK is a diameter so this line (chord) divides the circle into two arcs measuring 180°.
m(arc LJK) = m(arc LK) = 180°
2). m(∠JKL) = 28°
Therefore, by the property inscribed angle and intercepted arcs,
Intercepted arc (JL) = 2 × (Inscribed angle JKL)
m(arc JL) = 2(26°)
= 52°
Now we will use these two points to get the measure of arc JK.
m(arc JK) + m(arc LK) + m(arc JL) = 360°
m(arc JK) + 180° + 52° = 360°
m(arc JK) = 360° - 232°
= 128°
Option C will be the correct option.
Answer:
We do not have the function g(x), but this can be solved in a trivial way.
The average rate of change in a interval is the slope over that interval, so the average rate of change of g(x) in the interval 1 < x < 5 is
p = (g(x2) - g(x1))/(x2 - x1) where x2 > x1
p = (g(5) - g(1))/(5 - 1) = (g(5) - g(1))/4
Now, suppose that i have the new equation h(x) = g(x) + x
the rate of change of this function, the average rate of change in the interval will be:
p' = (h(5) - h(1))/(5 - 1) = (g(5) + 5 - g(1) - 1)/4 = (g(5) - g(1))/4 + 4/4 = p +1
so p' > p
and the average rate of change of h(x) is bigger than the one of g(x) in the interval 1< x < 5
