The answer to the question
Answer: I think the answer is D
Step-by-step explanation:
Answer:
sali's speed was 18.75 km/h
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, , so the speed of Jane will be:
Suppose, the speed of Sali is km/h
Sali caught up with Jane when they had both cycled 30 km.
So, the time required for Jane to cycle 30 km and the time required for Sali to cycle 30 km
Given that, Sali started to cycle 4 minutes or after Jane started to cycle. So, the equation will be.......
- 7 1/5 < - 2.3 < 0 < π < 23/7 is ascending order of these numbers.
What do descending order and ascending order mean?
- Climbing down the stairs of numbers starting with their highest value is another way to think of descending.
- The slide is descended while moving down it.
- Ascending order, in which the numbers are organized from lower value to higher value, is the reverse of falling order.
The values are 0 , -2.3 , π , 23/7 , -71/5
first simplify all the values 0 , - 2.3 , 3.14 , 3.28 , -7.2
now arrange all value in Ascending order
- 7.2 < -2.3 < 0 < 3.14 < 3.28
- 7 1/5 < - 2.3 < 0 < π < 23/7

(√3 - <em>i </em>) / (√3 + <em>i</em> ) × (√3 - <em>i</em> ) / (√3 - <em>i</em> ) = (√3 - <em>i</em> )² / ((√3)² - <em>i</em> ²)
… = ((√3)² - 2√3 <em>i</em> + <em>i</em> ²) / (3 - <em>i</em> ²)
… = (3 - 2√3 <em>i</em> - 1) / (3 - (-1))
… = (2 - 2√3 <em>i</em> ) / 4
… = 1/2 - √3/2 <em>i</em>
… = √((1/2)² + (-√3/2)²) exp(<em>i</em> arctan((-√3/2)/(1/2))
… = exp(<em>i</em> arctan(-√3))
… = exp(-<em>i</em> arctan(√3))
… = exp(-<em>iπ</em>/3)
By DeMoivre's theorem,
[(√3 - <em>i </em>) / (√3 + <em>i</em> )]⁶ = exp(-6<em>iπ</em>/3) = exp(-2<em>iπ</em>) = 1
