</span>Johann walked 1.2 feet every second.
Find the total feet that Johann walked for 5 seconds.
First, let’s have the given numbers:
=> 1.2 feet
=> 5 second
he walked 1.2 feet in every 1 second. So simply multiply 1.2 x 5 seconds to get
the total feet that Johann walks.
=> 1.2 feet x 5 seconds
=> 6, Thus, Johan walked 6 feet in 5
seconds.
Unit Rate = 1.2 / ft
Unit rate = 6 feet / 5 seconds</span>
The first word of the question is cut out of the picture, so we don't exactly know what the assignment is. But we can see that the graph of f(x) will do something weird when x=-3, because the denominator will be zero, and division by zero doesn't even have a definition or meaning. Just for fun, you should go ahead and calculate the numerator when x=-3, and that totally blows your mind, because the numerator is zero too. So you've got. f(-3)= 0/0 , and I can pretty much guarantee that you won't be able to plot that point anywhere on the graph. (I'm pretty sure that f(-3) is actually going to turn out to be -13, but even if I'm correct, you probably haven't learned that little calculus trick yet, so don't worry about it. As far as you're concerned, f(-3) is 0/0, and can't be plotted.)
You can solve this problem and calculate the height of the pole, by following the steps below:
Tan(α)=Opposite leg/Adjacent leg
α is the angle of elevation (α=<span>67°).
</span> The opposite leg is <span>the height of the pole. Let's call it "x".
</span> Adjacent leg=137 feet
When you substitute these values into the formula Tan(α)=Opposite leg/Adjacent leg, you have:
Tan(α)=Opposite leg/Adjacent leg
Tan(67°)=x/137
You must clear the "x"
x=137xTan(67°)
x=322.75
W<span>hat is the height of the pole?</span>
The answer is: The height of the pole is 322.75 feet.
The answer is a hope it's right if not I'm srry
