Answer:
D) < 3, 7)>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given that the vector < 3 , -7 >
Given the vector reflection across the x-axis
(x,y) → (x , -y)
The vector < 3,-7> →< 3, -(-7)>
< 3,-7> →< 3, 7)>
Answer:
tan (48°19'23'') => 1.1232
Step-by-step explanation:
60' minutes are present in a degree, and 60 * 60' seconds are present in a degree;
48°19'23'' = 48 + 19/60 + 23/3600
= 
= 
= 
= 48.323°
tan(48.323°) = 1.1232
Answer:
2/5: 4/5
Step-by-step explanation:
2/5 of a mile : 16/20 of a mile
It can be made equivalent in 2 ways. Either make the first fraction equivalent by multiplying it with 4 or make the second fraction equivalent to the first by dividing it by 4
- 2*4/5*4: 16/20
= 8/20: 16/20
2. 2/5: 16/4/20/4
= 2/5: 4/5
It is better to choose a smaller fraction as they are easy to solve .
So the total distance he covered = 2/5+ 4/5= 6/5= 1 1/5 miles or 1.20 miles from school to home.
