Just find the slope between the points
basically find (f(10)-f(7))/(10-7)
f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66
slope=(66-24)/(10-7)=42/3=14
average rate of change is 14
The figure is called an Acute Triangle. The Area is 199.96 centimeters squared. The perimeter (or circumference) is 68.
Answer:
B
Step-by-step explanation:
We can use the law of cosinse:
=
− 2ab cos(C)
Suppose the two sides are a and b, and the angle betweent them is C.
=
− 2*3*4 cos(60)
We can simplify this to get
=25-12=13
c=
Answer choice B
9514 1404 393
Answer:
(d) see below
Step-by-step explanation:
Since each grid square is 1/4 unit. the coordinates in terms of grid squares are ...
A(0.50, -1.25) ⇒ (0.50/.25, -1.25/.25) = (2, -5) . . . grid squares
Point A is located 2 squares right and 5 squares down on the grid. This matches choice D.
