Answer:
the minimum is (1,-9)
Step-by-step explanation:
y = 5x^2 - 10x - 4
since the parabola opens upward 5>0, this will have a minimum
it will occur along the axis of symmetry h=-b/2a
y =ax^2 +bx+c
h = -(-10)/2*5
h = 10/10 =1
the minimum occurs at x =1
the y value for the minimum is calculated by substituting x =1 back into the equation
y = 5 * 1^2 - 10*1 -4
y = 5*1^2 -10 -4
y = 5-10-4
y = -9
the minimum is (1,-9)
Remember, to the find the volume, you have to do length*width*height.
So it would be 7/4 * 3/2 * 1/2
To answer this, multiply all the numerators together, and multiply all the denominator together.
This would be:
21/16
So the answer is 21/16 cm^3 or 1.3125 cm^3.

X is equal to 4
Because RS + ST=RT
So basically x+3x=5x-4
4x=5x-4
-4x -4x
-1x=-4
x=4
C) m = 8h
In the model, Kevin is earning $8 per hour he works.
I think the answer is 0.4
