The some of an Isosceles triangle is 180.
if vertex B = 130 degrees then the other two must be equal 50 degrees. so you divided 50 by 2 which equals 25.
in this case you have 2 points which equal 50. so you take the one which is the closest to 25. which is the last point. m<A = 20 and m<C + 30.
I hope this is right.
I assume you mean 4(3^x) as in this is an exponential function.
The average rate of change is simply the change in y divided by the change in x so:
(4(3^2-3^1))/(2-1)
4(9-3)
4(6)
24
....
(4(3^4-3^3))/(4-3)
4(81-27)
4(54)
216
So the average rate from 3 to 4 is 216 and from 1 to 2 is only 24.
So the average rate of B to A is 216/24=9, is 9 times greater than A.
The average rate of change is not constant as this is an exponential function.
Answer:
4^9
Step-by-step explanation:
Answer:
-10
Step-by-step explanation:
x+75=180-(x+125)
2x=-20
x=-10
