Answer:
To the nearest hundredth, this is 30.79 units
Step-by-step explanation:
To find the length of the arc, we simply apply the length of arc formula
Mathematically, that would be;
theta/360 * 2 * pi * r
Theta here is 98
r is 18 units
So the length of the arc will be;
98/360 * 2 * 22/7 * 18
= 30.7876 units
to the nearest hundredth, this is;
30.79 units
Answer: -7/3
Step-by-step explanation:
Perpendicular lines have slopes that are negative reciprocals of each other.
Answer:
Step-by-step explanation:
6x-10x^2+3-(5x^2+3x-4)
when there is a - in front of an expression in (), change the sign of each term in the expression
6x-10x^2+3-5x^2-3x+4
now collect like terms
3x-10x^2+3-5x^2+4
3x-15x^2+3+4
3x-15x^2+7
now use the commutative property to reorder the terms
-15x^2+3x+7
=-15x^2+3x+7
