Answer: a=1.16 and b=0.12
Step-by-step explanation:
We know that the residual value= given - predicted
For x=3
The given value =1.1
The residual value=-0.06
Thus
The predicted value (a)= given- residual
For x=4
The given value =3.1
The predicted value = 2.98
Thus
The residual value (b) = given - predicted
Answer:
Area of circle - Area of square
radius of circle is 8m
side of squre os 12m
Step-by-step explanation:
Area of circle is pie r^2
22/7 × 8 × 8
22/ 7 × 64
= 201.14m^2
Area of square is side ^2
12 ×12
= 144m^2
hence 201.14 - 144
= 57.14m^2 is the area of shaded figure
GOOD LUCK FOR THE FUTURE! :)
Answer:
337.50
Step-by-step explanation:
Sin57 = x/12
x = 12sin57 = 10 approximately
Answer:
pi/12 rads
Step-by-step explanation:
We know -pi/12 goes clockwise. Since it goes down pi/12 radians, the answer is simply pi/12 because when it connects to the x axis, it makes an ACUTE angle (which is the reference angle, and is always positive) of pi/12 rads.
