4^-5=1/1024 or 2/2048 or 3/3072
V=(1/3)hpir^2
v=130
h=13
r=x
130=(1/3)(13)pix^2
times both sides by 3
390=13pix^2
divide both sides by 13
30=pix^2
divide both sides by pi
30/pi=x^2
sqrt both sides
x≈3.09
radius is abou 3 units
Answer:

the charge is $5 dollars per mile
Step-by-step explanation:
He truck is rented at $40 per day plus they charge per mile of use the truck travel 15 miles in one day and the total charge was 115
LEt x be the charge in dollars per hour
Initial charge is 40 and 15 miles travelled in one day
total charge = 15x + 40
Given : total charge is 115
So the equation becomes

Now we solve for x
Subtract 40 from both sides

Divide both sides by 15
x= 5
so , the charge is $5 dollars per mile

The y factors of the given quadratic equation is -1 and 40/22.
According to the statement
we have given that the equation and we have to find the factors of those equation.
So, The given equation is:

where y is the factors of that equation.
So, we have to find the factors of the given quadratic equation.

Then after solving it become

Then take negative sign common from it then

Make the factors of this quadratic equation

Now take common values 22x and 40 from the equation then

Then it become

Then the values of x become from the equation is

The value of the factors y is -1 and 40/22.
So, The y factors of the given quadratic equation is -1 and 40/22.
