Answer:
400(π+2) feet square
Step-by-step explanation:
let x be the diagonal of the cage=40√2 at the same time it is the radius of the circle ( the tiger can go in circle)
but since the cage is part of the circle and not full turn πr²/8
area of the circleπr²+ half area square
(π(40√2)²)/8 +40²/2
3200π/8+1600/2
400π+800
400(π+2) feet square
Jessica bought 2.25 yards more material than Derek. Hope this helped!
The answer is B because you have to do the opposite which means you have to subtract -9-2=-11
Answer:
4,684 km
Step-by-step explanation:
Let y= mx-2 be the tangent line to y=x^2-4x+2 at x=a.
Then slope, 
Hence the equation is y=(2a-4)x-2
Let's find y-coordinate at x=a using tangent line and curve.
Using tangent line y at x=a is (2a-4) a -2 
Using given curve y-coordinate at x=a is 
Let's equate these 2 y-coordinates,



a=2 or -2.
If a=2, 
If a=-2,
Hence m values are 0 and -8.
