Where did you get that "-24"? 4(-3/2)^2= 4(9/4)= 9 so your equation should be 9= 9+ k and that leads to k= 9- 9= 09= ah^2+ k
9= 4(-3/2)^2+ k
k= 9- 24
k= -16
The best way to check if a value for a, h, and k is correct is to use the formula k = a(h/2). Plug in the values for a, h, and k and solve for k. If the resulting value for k matches the given value, then the values for a, h, and k are correct.
Yes, you can use any units for a, h, and k as long as they are consistent. For example, if a is given in meters, h should also be in meters and k will be in square meters.
In the formula k = a(h/2), a represents the length of the base of a triangle, h represents the height of the triangle, and k represents the area of the triangle. This formula is used to calculate the area of a triangle given its base and height.
If the resulting value for k does not match the given value, then the values for a, h, and k are incorrect. This could be due to incorrect input values or a mistake in calculations.
Yes, you can use a calculator to check the correctness of a, h, and k. Make sure to enter the values correctly and use the correct order of operations when solving the formula k = a(h/2).
