Part 1) There are a lot of examples. The Colliseum in Rome is an example of an ellipse in architecture. Tires of cars are in a very good approximation a circle. The Arch of triumph is an example of a parabola in the real world, as are many bridges, such as the golden gate bridge.
Part 2) The Golden Gate Bridge is a suspension Bridge spanning the Golden Gate, a short strait in San Francisco. It is one of the wonders of the Modern World and it was opened in 1937. It cost around 500 million dollars in today's currency and it is one of the longest suspension bridges in the world and from land to land the distance is 1280 m. The height of the suspensions is 230 m.
Part 3) We can think of a parabola of the form y=ax^2 where we need to substitute the values to find a.
Answer:
Step-by-step explanation:
It means that you will a 2 or a 3 or a 4 or a 5 or 6.
All of these are permitted.
So the probability of getting at least a 2 is 5/6.
So, we are given 5^8. It was happy and content. But then... we had to write it as a quotient of two exponential terms with the same base in four different ways and use negative or zero exponents and ahhhhhh!!!
... anyways...
We'll build a quotient of two exponential terms with the same base 5. Something like this:
5^a / 5^b
We need them to make 5^8 when we are done. I'll first use a zero exponent.
[1] Now, zero exponents are nice since they make things equal 1. Like 5^0 = 1. Well, obviously, 5^8 / 1 = 5^8. So, our first quotient can be:
5^8 / 5^0
Done.
[2] Let's try this on its head. This one's a little weird. Remember that negative exponents flip things upside down. So 5^-8 = 1/5^8 and 1/5^-8 = 5^8 for example. In fact... that's the answer!
5^0 / 5^-8 = 5^8
Done.
[3] Let's try to not use 0s or 8s. We can be clever and do something like this:
5^-1 / 5^-9
What the heck is that? Well, we just flip them and get:
5^-1 / 5^-9 = 5^9 / 5^1 = 5^8
Done.
[4] Can you come up with one last trick on your own? Try it!
Answer: The float committee made a scale model of their float before they started construction. The float committee used the scale 1 inch : 3 Feet to create their model. The actual float will be 18 feet long.
So this being said.
Step-by-step explanation:
Your answer should be 6 inches. I hope this helps!
