Answer:
A.) 31.579
Step-by-step explanation:
12/38 · 100= 31.579%
12/38 men agreed so to make it into a percentage, multiply by 100.
First, write down y=a(x-the x coordinate of the vertex)^2+the y coordinate of the vertex)
second, plug the x coordinate and coordinate of the given point in the above equation to find out a
For example, vertex is (1,2), the point is (3,4)
y=a(x-1)^2+2
then plug in x=3, y=4 in the above equation to find out a
4=a(3-1)^2+2
4=4a+2
4a=2
a=1/2
the equation of the parabola with a vertex at (1,2) and passes through the point (3,4) is 0.5(x-1)^2+2
Given: A = { 1, 2, 3, 4 } , B = { 1, 3, 5, 7 } , C = { 2, 4, 6 } .

Step-by-step explanation:
I hope you like my answer. Thanks.
First we need to found out how many pounds and luggage to small plane can carry, now that we know there is 490 pounds of mail.
1050 - 490 = 560
Now we need to find out the maximum number of passengers that can board the plane.
70p = 1050
We know that there are 560 avalible pounds left on the plane
70 x 8 = 560
560 + 490 = 1050.
Well if we go back to the question it says less than 1050. This means that 8 passengers times 70 pounds each would not be correct because the small airplane can carry less than 1050 pounds.
70 x 7 = 490
490 + 490 = 980
980 is less than 1050
So the answer would be 7 passengers.
7 Passengers is the maximum amount of passengers that can be taken.
I hope this helps!
