Answer:
20 Students
Step-by-step explanation:
If there is 1 chaperone for every 4 students, and there are a total of 5 chaperones on the trip, you can use this information to know that..
If there are 5 chaperones and 4 students for each chaperone, that would give you 20 students!
SA=2pir^2+2hpir=2pir(r+h)
h=2r=2(2x+3)=4x+6
SA=2pi(2x+3)(2x+3+4x+6)
SA=(4x+6)(pi)(6x+9)
SA=24πx²+27πx+54π
Answer:
y = 3x+9
Step-by-step explanation:
The standard form of equation of a line is in the form y = mx + c
m is the gradient
c is the y intercept
Get the y-intercept
Substitute m = 3 and the point (-2, 3) into the formula y = mx+c
3 = 3(-2) + c
3 = -6+c
c = 3+6
c = 9
Get the required equation;
y = 3x + 9
Hence the required equation is y = 3x+9
