please show me how you got the answer and make sure it is right
The curve formed by a rope bridge can be modeled by the relation y = x^2 - 11x + 10, where "x" is the horizontal distance in metres and "y" is the height in metres. What is the horizontal distance from one end of the bridge to the other end?

A nutrition store in the mall is selling “Memory Booster,” which is a concoction of herbs and minerals that is intended to improve memory performance, but there is no good reason to think it couldn't possibly do the opposite. To test the effectiveness of the herbal mix, a researcher obtains a sample of 8 participants and asks each person to take the suggested dosage each day for 4 weeks. At the end of the 4-week period, each individual takes a standardized memory test. In the general population, the standardized test is known to have a mean of μ = 8 (Set the significance level➔ = .06
our odometer reads 4,261 miles. You drive your car until the odometer reads 4,751 and your car used 25 gallons of gasoline during the trip. About how many miles per gallon has your car been getting? Round up to the highest ten.
In December 2018, the average price of regular unleaded gasoline excluding taxes in the United States was $3.06 per gallon. Assume that the standard deviation price per gallon is $0.11 per gallon and use Chebyshev's Inequality to answer the following.
(a) What minimum percentage of gasoline stations had prices within 2 standard deviations of the mean?
(b) What minimum percentage of gasoline stations had prices within 1.5 standard deviations of the mean? What are the gasoline prices that are within 1.5 standard deviations of the mean?
(c) What is the minimum percentage of gasoline stations that had prices between $2.62 and $3.50?
(a) At least

% of gasoline stations had prices within 2 standard deviations of the mean.
(Round to two decimal places as needed.)
The population average fuel efficiency of U.S. light vehicles for 2005
was 21 mpg. If the standard deviation of the population was 2.9 and
the gas ratings were normally distributed, what is the probability that
the mean for a random sample of 25 light vehicles is under 20 mpg?

Madera's mayor is watching a car from the ledge of the water tower. The car is directly approaching the water tower. When first noticed, the angle of depression to the car is 58°. When the car stops, the angle of depression is 77°. The mayor's line of sight is 127 feet above the ground.
Part 1
How far did the car travel from when it was first noticed until it stopped? Round to the nearest foot.
The car traveled ___________ feet from when it was first noticed until it stopped.
Part 2
Explain how you determined the distance the car had traveled by applying your understanding of the angles and the height of the mayor standing on top of the water tower.
