Answer:
I think it would
Step-by-step explanation:
The equation would be: y = 8x + 25
Answer:
i)
ii)
Thinking Process:
This can either be solved using complex variables or simply trigonometry (they are all the same in a way)
But we'll simply go with trigonometry and good old Pythagorean theorem.
Solution:
For Cartesian coordinates are:
To covert them into
We can use:
- The Pythagoras theorem to find
- Arctangent to find
These are related since:
So, let's start solving:
Part a) (4,-4)
For r:
i) for we'll go with
ii) for we'll go with
For theta:
One thing to keep in mind is that the point (4,-4) lies in the 4th quadrant of the xy-plane, and the range given for is . So we have to add to our answer (we have gone around the circle and stopped at the same place as radians)
radians
radians
The Answer for part(a) is
Part b) (-1, sqrt(3))
For r:
i) for
ii) for
For theta:
this not in range of theta: .
and the point lies in the 2nd quadrant, so we can add radians to our answer
in range:
The Answer for part(b) is
Answer:
Hindu astronomer discovered 0 by using math. They use zero because they use it ion a number line with positive and negative numbers. They also use the 0 for counting the numbers.
Step-by-step explanation:
Answer: 20,000
Step-by-step explanation:
We can estimate the product of 5 and 4,257 by multiplying 5 by 4,000
5 * 4,000 = 20,000
The product of 5 and 4,257 is about 20,000
The real answer (not an estimate)
21,285
That is around 20,000 so we are correct
