Answer:
The area of sector AOB is 75.36 unit²
Step-by-step explanation:
Consider the provided information.
Circle O with minor arc AB=60 degrees and OA =12.
We need to find the area of sector.
Area of the sector: 
Substitute
and r =12 in above formula.




Hence, the area of sector AOB is 75.36 unit²
<span>2 significant digits.
Let's see what the range of possible values you can have for 1.3540980 if your uncertainty is +/- 2%
2% of 1.3540980 = 0.02 * 1.3540980 = 0.027082
So the lowest possible value for your result is
1.3540980 - 0.027082 = 1.327016
The largest possible result is
1.3540980 + 0.027082 = 1.38117996
Notice that only the 1st 2 digits of the result match which is reasonable since a 2% error means that your result is only accurate to within 1 part in 50.</span>

but i have to write more to let me post this so here it is
Answer:
y-5=3x-15
Step-by-step explanation:
Slope=(5+1)/(-6+8)
=6/2
=3
Equation of line passing throgh point (-6,5):
y-5=3(x-5)
y-5=3x-15

Step-by-step explanation:
(x+3)(x-4)
1.) use distributive property
=x(x-4)+3(x-4)
=x^2-4x+3x-12
=x^2-x-12
