25% as a fraction is 1/4 or 25/100 so as a decimal its 1/4 of 1 which is .25
(b^2+5)(−b^2+7)
Use the FOIL METHOD to expand.
-b^4 + 7b^2 - 5b^2 + 35
-b^4 + 2b^2 + 35

Step-by-step explanation:
The solutions to the systems of equations are at the points of intersection of the 2 graphed functions.
1
There are 2 points of intersection , so 2 solutions at
(0, - 3 ) and (4, 5 )
2
There is 1 point of intersection, so 1 solution at
(- 2, 5 )
3
There are no points of intersection , so no solution
Answer:
Step-by-step explanation:
The white area is the area of the circle minus the area of the triangle.
Aw=pr^2-hb/2
Aw=p4^2-6.5(6)/2
Aw=16p-19.5
The probability of selecting the white area is the white area divided by the area of the circle
P(W)=(16p-19.5)/(16p), p=3.14
P(W)=0.61
