Answer:
Substitute (x+4)2−16 ( x + 4 ) 2 - 16 for x2+8x x 2 + 8 x in the equation x2+y2+8x−6y=24 x 2 + y 2 + 8 x - 6 y = 24 . (x+4)2−16+y2−6y=24 ( x + 4 ) 2 - 16 + y 2 ...
Step-by-step explanation:
3 sides of square is 3*12=36 cm
perimeter for the full circle is 2 * pi * radius
which is =2 * 22/7 * 12 =75.43 cm
so 360° =75.43 cm
for 150° = 75.43/360 *150 =31.43
all together =36 +31.43 =67.43 cm
The area of the sector will also be 70/360
Sector area = 70/360 • pir^2
= 7/36 • pi • 8^2
A= 112/9 • pi
A= 39.1 inch^2
Answer:
a=4, k=2, and b= -pi/4

Answer: 47 students
Step-by-step explanation:
430 students went on a trip with the majority of them going on buses.
7 students however, had to use cars.
The number of students who used buses are:
= 430 - 7
= 423 students
The number of students in each bus is:
= No. of students taking buses / no. of buses
= 423 / 9 buses
= 47 students
