Answer:
19.63
Step-by-step explanation:
If the perimeter is 17.85, then it is equal to 2r+(2*3.14*r)/4. Solving this gives us r=5. Therefore, the quarter circle's area is (3.14*5^2)/4 = 19.625. Rounding this gives us 19.63
Answer:
1/3
Step-by-step explanation:
You can rewrite the equation like so:
2/3 + (-1/3)
2/3 - 1/3
The denominators are the same so you don't need to worry about that:
2/3 - 1/3 = 1/3
1/3 is your answer

Gradient of a line times the gradient of a line that is perpendicular to it is-1
M1M2=-1
2/3 times M2=-1
M2=-1 times 3/2
The gradient is =-3/2
