Answer:

  4(x-2)(x-1)^3(x+1)\sqrt{x-1}

Step-by-step explanation:

4x(x-1)^{9/2}-8(x-1)^{7/2}=4(x-1)^{7/2}(x(x-1)^{2/2} -2)=4(x-1)^{7/2}(x^2-x-2)\\\\=4(x-1)^{7/2}(x-2)(x+1)=4(x-2)(x-1)^3(x+1)\sqrt{x-1}

___

Among other things, the leading coefficient cannot be 2, as 4 is a factor of both the given terms.

Find the arc length, x, when
Arte-miy333 [17]

The arc length of the circle is 5π/9 units

<h3>How to determine the arc length?</h3>

From the question, we have the following parameters

Angle, ∅ = 5π/9

Radius, r = 1 unit

The arc length (x) is calculated as

x = r∅

Substitute the known values in the above equation

x = 5π/9 * 1

Evaluate the product

x = 5π/9

Hence, the arc length of the circle is 5π/9 units

Step-by-step explanation:

1. what is the change in Dan's total pay for each copy of math is fun he sells?

2. what is Dan's total pay if he doesn't sell any copies of math is fun?

Given

y=80x + 2400

When x=0

y=80(0)+2400

=0+2400

=2400

When x=1

y=80x + 2400

=80(1) + 2400

=80+2400

=2480

change in Dan's total pay for each copy of math is fun he sells is

= 2480 - 2400

=80

2. Dan's total pay if he doesn't sell any copies of math is fun?

y=80x+2400

When x=0

y=80(0)+2400

=0+2400

=2400
