Answer:

The positive difference between the a values is 0.5

Step-by-step explanation:

we know that

Both parabolas cross the x axis at (-4,0) and (6,0)

so

The general equation is

y=a(x+4)(x-6)

<em>Find the value of a in the first parabola</em>

The y-intercept is (0,-12)

so

For x=0, y=-12

substitute

y=a(x+4)(x-6)

-12=a(0+4)(0-6)

-12=a(-24)

a=0.5

<em>Find the value of a in the second parabola</em>

The y-intercept is (0,-24)

so

For x=0, y=-24

substitute

y=a(x+4)(x-6)

-24=a(0+4)(0-6)

-24=a(-24)

a=1

<em>Find the positive difference between the a values for the two functions</em>

so

1-0.5=0.5

4.) Determine the missing side of a rectangle with an area of 480 cm² and a length of 32 cm. Please show your work.​
asambeis [7]

Answer:

w = 15 cm

Step-by-step explanation:

We want to find the width, as the area of a rectangle is length (l) * width (w).

Since we know the area and the length, we have 480 = 32w

Isolating w by dividing both sides by 32 gives us w = 15 cm
