Answer:
A ≈ 35.3 units²
Step-by-step explanation:
Calculate the radius CB using Pythagoras' identity in the right triangle.
CB² + AB² = AC²
CB² + 6² = 9²
CB² + 36 = 81 ( subtract 36 from both sides )
CB² = 45 = r²
Then area of quarter circle is
A =
× πr² =
× π × 45 ≈ 35.3
Answer:
x=1
Step-by-step explanation:
Subtract
18
from both sides
Simplify
3
Subtract
2x
from both sides
Answer:
k=8
Step-by-step explanation:
Cab 1 : 1/km
Cab2: 0.5 /km with Base charge =4
x=0.5 x+4
x-0.5x=4
0.5x=4
4/0.5=x
x=8
Assume x=k
k=8
The reason why you can’t divide zero us because zero is an undefined number. Dividing is breaking something into group and you simply can't break anything if it's not there.
