Ok, here we go. Pay attention. The formula for the arc length is

. That means that to use that formula we have to find the derivative of the function and square it. Our function is y = 4x-5, so y'=4. Our formula now, filled in accordingly, is

(that 1 is supposed to be negative; not sure if it is til I post the final answer). After the simplification we have the integral from -1 to 2 of

. Integrating that we have

from -1 to 2.

gives us

. Now we need to do the distance formula with this. But we need 2 coordinates for that. Our bounds are x=-1 and x=2. We will fill those x values in to the function and solve for y. When x = -1, y=4(-1)-5 and y = -9. So the point is (-1, -9). Doing the same with x = 2, y=4(2)-5 and y = 3. So the point is (2, 3). Use those in the distance formula accordingly:

which simplifies to

. The square root of 153 can be simplified into the square root of 9*17. Pulling out the perfect square of 9 as a 3 leaves us with

. And there you go!
Answer: the scale factor is 3/4

Answer:linear equations
Step-by-step explanation:
As given he made 3/5 of basket he shot.
So we can find number of basket made by Everett equal to 3/5 of total number of shot .
So if total number of shot is 60.
Then the number of basket made by Everett =

of 60.

So the number of basket made by Everett in 60 shots = 36.
8/20as well,since the number of green beads and yellow beads is the same,so equal probability
