Answer:
Step-by-step explanation:
Let the distance be d and average speed be v.
Half of the distance the speed was 2/3v
Let the speed be xv in the second half of the distance.
<u>Then time is:</u>
- d/v = d/2 : (2/3v) + d/2 : (xv)
- d/v = 3/4(d/v) + (1/2x)(d/v)
- 1 = 3/4 + 1/2x
- 1/2x = 1 - 3/4
- 1/2x = 1/4
- 2x = 4
- x = 2
The rest of the road car has to ride with speed of 2v
In spherical geometry there is only one equilateral triangle. False
Answer:
$46185.04
Step-by-step explanation:
80000 = X(1 + 0.0275/12)^(20×12)
X = 46185.03749
Consider this option:
1. rule: Circle is the locus of the points which are on the same distance from the given point. Common view of the equation is: (x-a)²+(y-b)²=r², where r - the distance from the given point to the described locus, a&b - coordinates of the given point.
2. using item 1:
(x+2)²+(y-1)²=3² or (x+2)²+(y-1)²=9.
