A small boat leaves the dock at Camp DuNuthin and heads across the Nessie River at 17 miles per hour, relative to the water, at a bearing of S60° W. The river is flowing due east at 6 miles per hour. What is the boat's true speed and heading? Round the speed to the nearest mile per hour and express the heading as as a bearing with the angle rounded to the nearest tenth of a degree
Answers
The speed of the boat will be 12.18 mph, and the angle of its direction measured from the positive x-axis will be 224.3°
What we can say about the boat speed?
First, let's define North as the positive y-axis and east as the positive x-axis.
In this coordinate axis, the angle S 60° W is equal to 210°.
Then the velocity of the boat will be:
v = (17mph*cos(210°), 17mph*sin(210°))
Now we also need to add the speed of the river, which is 6mph to the east, then the final velocity of the boat will be:
v = (17mph*cos(210°) + 6mph, 17mph*sin(210°))
v = (-8.72mph, -8.5 mph)
Then the speed of the boat will be:
|v| = √( (-8.72mph)^2 + (-8.5 mph)^2) =12.18 mph
And the angle, measured from the positive x-axis, will be given by the arctangent of the quotient between the y-component and the x-component:
Atan(-8.5 mph/-8.72mph) = 224.3°

“A football is punted into the air. It’s height in feet is found by using the equation h(T) = -5t squared +27.5t+2.5, where T represents the time in seconds and h(T) represents the height of the football in feet. How high does the football get. Round to the nearest thousandth”
Answers
How high the football gets is a function of the maximum height of the ball
The football goes 40.313 ft high
How to calculate how high the football getThe equation that models the height of the ball is given as:
[tex]h(t) = -5t^2 +27.5t+2.5[/tex]
Differentiate the function
[tex]h'(t) = -10t +27.5[/tex]
Set to 0
[tex]-10t +27.5 = 0[/tex]
Collect like terms
[tex]10t =27.5[/tex]
Divide by 10
[tex]t =2.75[/tex]
Substitute 2.75 for t in [tex]h(t) = -5t^2 +27.5t+2.5[/tex] to calculate how high the ball get
[tex]h_{max} = -5 * 2.75^2 +27.5 * 2.75+2.5[/tex]
[tex]h_{max} = 40.3125[/tex]
Approximate
[tex]h_{max} = 40.313[/tex]
Hence, the football goes 40.313 ft high

After the December 7, 1941, Japanese attack on the American naval fleet at Pearl Harbor, Hawaii, the U.S. was thrust into World War II (1939-45), and everyday life across the country was dramatically altered. Food, gas and clothing were rationed. Communities conducted scrap metal drives. To help build the armaments necessary to win the war, women found employment as electricians, welders and riveters in defense plants. Japanese Americans had their rights as citizens stripped from them. People in the U.S. grew increasingly dependent on radio reports for news of the fighting overseas. And, while popular entertainment served to demonize the nation’s enemies, it also was viewed as an escapist outlet that allowed Americans brief respites from war worries.
