Answer:
Depends on amount of students.
Step-by-step explanation:
You would just multiply the amount of students time (1 1/2) = (1.5)
Ex:
3 students 4 1/2 hours
4 students 6 hours
5 students 7 1/2 hours
and so on
Answer:
15/56x^(-4/7) + 32x^3 + 6.
Step-by-step explanation:
Using the rule for algebraic differentiation:
If y = ax^n, dy/dx = anx^(n-1).
So :
If y = 5/8x^3/7 + 8x^4 + 6x - 9
dy/dx = 5/8* 3/7 x^(3/7-1) + 8*4 x^(4-1) + 6x(1-1)
= 15/56x^(-4/7) + 32x^3 + 6.
Answer:
i) 21 and ii) 6
Step-by-step explanation:
i) If X=4 and Y=6, then:
3X+9, replacing X
3(4) + 9
12 + 9
21
ii) 4X-Y
4(3) - 6
12 - 6
6
Answer:
They have to drive 
miles more
Step-by-step explanation:
Given:
Total Distance of the road trip = 
miles
Distance travelled already = 
miles.
To Find:
How much farther do they have to drive = ?
Solution:
The distance they have to travel farther = Total distance - distance travelled
The distance they have to travel farther = 
=>
=>
=>
=>
=>
The simplified rational expression for that is 2
