The graph of a twice differential function is shown at right. Which of the following is true?
Answer:
(C)
Step-by-step explanation:
looking from the slope: f'(2) is negative
f(2)=0
the curve concave upward: f''(2) is positive
f'(2)<0
f(2)=0
0<f''(2)
f'(2)<0<f''(2)
The expression which is true n the graph of a twice differential function is f' (2) < 0 < f'' (2) so, option C is correct.
What is a differential function?A function that has a derivative at each point in its domain is referred to as a differentiable function of one real variable in mathematics. In other words, each interior point in the domain of a differentiable function's graph has a non-vertical tangent line.
Given:
The coordinate of the graph is shown in figure (2, 0),
As we can see from the graph, the slope: f' (2) is negative (Downwards)
Again, from the graph
f(2) = 0
Thus, the curve concave upward: f'' (2) is positive (upward)
f' (2)<0
f (2)=0
0 < f'' (2)
f' (2) < 0 < f'' (2)
Therefore, f' (2) < 0 < f'' (2) is true in the given graph.

Jodie ran at an average speed of 10 km/h for 15 minutes.
How far did she run in km?
Answer:
2.5 km
Step-by-step explanation:
15 minutes is
15 minutes * 1 hour/ 60 minutes = 1/4 hour
15 minutes = 1/4 of an hour
10 km/ hour * 1/4 hour = 10/4 km = 2.5 km
Answer:
In total she ran 2.5km/h in 15 minuets.
Step-by-step explanation:
Since 15 minuets is a quarter of an hour you can divide the 10km/h by 4 to get 2.5km/h.

D. 186cm^2
HELP ME PLS ASAP PLS PLZ PLZ PLS
Answer:
78cm^2
Step-by-step explanation:
You'd want to separate the two shapes into a rectangle and triangle. So you'd have one rectangle with one side being 2 and the long side 12. (2 * 12 = 24). Then a triangle with a base of 9 and a height of 12. (9 * 12 = 108 / 2 = 54) Then you add both areas together to get 54 + 24 = 78.
Answer:
B: 78
Step-by-step explanation:
cut it in half into a rectangle and traingle
the rectangles area is 2x12=24
The area of the triangle is 9x12=108 108/2 = 54
then add the 2 areas to get B:78

Answer:
3 units
Step-by-step explanation:
Subtract x(2) by x(1), and then you can ignore the y parts because it's all on the same y-axis. x(2) is 5, x(1) is 2, 5-2=3, so the length of side BC is 3 units.

Find the cosine of each acute angle
What is cosine?
Well, cosine is adjacent side divided by the hypotenuse.
cos M = 20/36
Reducing 20/36 to the lowest terms we get
cos M = 5/9
cos N = 30/36
Reducing 30/36 to the lowest terms we get
cos N = 5/6
