(12) the earth is one astronomical unit from the
sun i. e. 1 au= 93 million miles. the angular speed of the earth
eling around the sun is approximately 0.9863 degrees per
day. if we assume the orbit of the earth is completely circular,
what is the linear speed in miles per hour?
-- miles per hour
if it takes you 4 hours to drive to dallas for ou-texas week-
end, how much of a revolution did the earth make in that time?
round to four decimal places ( in revolutions)

3,821,912.5 miles/hour is the linear speed of the earth around the sun.

The Earth make 0.02616 revolutions in 4 hours.

Step-by-step explanation:

v =  linear speed

r = radius from the center

= angular speed

The angular speed of the Earth around the sun = 0.9863 degrees/day

Distance of the earth from the sun = r = 1 AU =

Linear speed of earth around the sun = v

v =

1 day = 24 hours

v=

3,821,912.5 miles/hour is the linear speed of the earth around the sun.

Duration  of drive from Dallas to Texas = 4 hours

Miles of revolution of earth covered in 4 hours :

The revolution of earth in 15,287,650 miles will be:

=0.026162420 revolution ≈ 0.02616 revolutions

The Earth make 0.02616 revolutions in 4 hours.

step-by-step explanation:

explanation:

the loan estimate encourages consumers to shop. since it is the lenders who are required to issue a standardized loan estimate in a specific time frame, this way consumers are provided an opportunity to compare lenders and their products. otherwise consumer wouldn't know the benefits offered by other lenders.  

if a loan originator does not provide a loan estimate within 3 business days of receiving a completed loan application, that lender is in violation. lenders are required to issue a loan estimate within 3 days of applying for a loan or within 7 days prior to closing. having a loan estimate has following information.

not having loan estimate won't give you an idea of money to be borrowed.

you get to know your interest rates.

you also get to know if your interest rate can or may vary.

not having a good faith estimate can keep you unaware of aforementioned points.
