Hey there!
ASSUMING!
-3/7m = 12
IF SO!
DIVIDE -7/3 to BOTH SIDES
-7/3 * -3/7m = 12 * 7/3
CANCEL out: -7/3 * (-3/7) because it give you 1
KEEP: 12 * (-7/3) because it give you the m-value
NEW EQUATION: m = 12 * (-7/3)
SIMPLIFY IT!
m = -28
Therefore, your answer is: m = -28
(Option A)
Good luck on your assignment & enjoy your day!

Did you notice the little box with corners marked in the angle down at the bottom ?
That angle is a right angle, and <em>this triangle is a right triangle</em> !
This piece of information is a big help. It breaks the problem wide open.
You know that in order to find the longest side of a right triangle . . .
-- Square the length of one short side.
-- Square the length of the other short side.
-- Add the two squares together.
-- Take the square root of the sum.
One short side=48. Its square = 2,304.
The other short side=48. Its square = 2,304.
Add the two squares: 2,304 + 2,304 = 4,608
The square root of the sum = √4,608 = <em><u>67.88</u></em> (rounded)
Answer:
4 meters
Step-by-step explanation:
Given a quadratic equation in which the coefficient of
is negative, the parabola opens up and has a maximum point. This maximum point occurs at the line of symmetry.
Since the divers height, y is modeled by the equation

Step 1: Determine the equation of symmetry
In the equation above, a=-1, b=2, c=3
Equation of symmetry, 

Step 2: Find the value of y at the point of symmetry
That is, we substitute x obtained above into the y and solve.

The maximum height of the diver is therefore 4 meters.
