Answer:
3750 feet long
Step-by-step explanation:
you would multiply the inches of the model ( 15) by the feet of the scale ( in this case 250) to get the real amount of feet for the boat.
Answer:
-1/12
Step-by-step explanation:
1/4 - 1/3 = 3/12 - 4/12 = - 1/12

Answer:
yes
Step-by-step explanation:
The line intersects each parabola in one point, so is tangent to both.
__
For the first parabola, the point of intersection is ...
y^2 = 4(-y-1)
y^2 +4y +4 = 0
(y+2)^2 = 0
y = -2 . . . . . . . . one solution only
x = -(-2)-1 = 1
The point of intersection is (1, -2).
__
For the second parabola, the equation is the same, but with x and y interchanged:
x^2 = 4(-x-1)
(x +2)^2 = 0
x = -2, y = 1 . . . . . one point of intersection only
___
If the line is not parallel to the axis of symmetry, it is tangent if there is only one point of intersection. Here the line x+y+1=0 is tangent to both y^2=4x and x^2=4y.
_____
Another way to consider this is to look at the two parabolas as mirror images of each other across the line y=x. The given line is perpendicular to that line of reflection, so if it is tangent to one parabola, it is tangent to both.
Answer:
Each class receive $85.
Step-by-step explanation:
So what you will be doing is dividing $4,250 and the 50 classes.
Hope this helps or is right at least :)
