Average rate of change means find the slope of the secant line. So if there is a function f(x) and you want to find the average R.O.C over the interval [a,b], it would be (f(b)-f(a))/(b-a)
1. (f(3)-f(1))/(3-1)= (0-(-2))/2= 1, so D.
2. Same concept; (8-4)/(3-1)=2, so A.
3. Again, (39-(-1))/5= 8, B.
Answer:
C; D; E
Step-by-step explanation:
✔️Angles in a straight line = 180°
Therefore, m<5 + m<6 = 180° is correct.
✔️Exterior angle of a triangle = the sum of the opposite interior angels based on the exterior angle theorem of a triangle.
Therefore,
m<2 + m<3 = m<6 is correct.
✔️The sum of m<2 + m<3 + m<5 = 180° is correct. This is true based on the sum of triangle theorem.
Shidddd lil buddy, try the 3rd one
Well let me solve it like this:
As we know the area is h(a+b)/2,
So what we do is:
<span>h (180/2) = 8100 </span>
<span>90h = 8100 </span>
<span>h = 90
</span>I hope this is easy to understand
Answer:
x=1 and y=10 (1,10)
Step-by-step explanation:
2+30=32
10=1+9
