Multiply by 2 which will get you a diameter and then multiply it by pi which is 3.14.
Letter C is correct.
When the function is even, (all powers are even) both ends will go in the same direction.
In this case since the leading coefficient is negative, both ends will go down.
Answer:
You should stick with option D
Answer:
Angle ADC = 80 degrees
Step-by-step explanation:
Here, we want to find the measure of angle ADC
mathematically, sum of angles at a point is 360
Thus;
x + 3x + x + 10 = 360
5x + 10 = 360
5x = 360-10
5x = 350
x = 350/5
x = 70
From the diagram;
angle ADC is (x + 10)
so we have; (70 + 10) = 80 degrees
Answer:
acute and obtuse
Step-by-step explanation:
the acute is less than 90 degrees and obtuse is more than 90 degrees
