Answer:
why does this hurt my head so much
Step-by-step explanation:
Okay so first off first off I believe 4-6 is linear because it is increasing at a steady rate and 7 is exponential because it has a constant rate of growth. I’m not 100% I’m correct on that. 8 is linear, 9 is exponential.
For 4: f(x)=-1/2x + 1
5: f(x)=-2x +4
That’s all I know right now. I hope it helps a little bit

Answer:
2198 cm²
Step-by-step explanation:
Total surface area of a cylinder = 2πrh + 2πr²
Radius, r = diameter/2
= 20cm/2
= 10 cm
Height, h = 25 cm
Total surface area of a cylinder = 2πrh + 2πr²
= 2*3.14*10*25 + 2*3.14*10²
= 1,570 + 6.28*100
= 1,570 + 628
= 2198 cm²
Total surface area of a cylinder = 2,198 cm²
Answer:
n=-1
Step-by-step explanation:
7n + 28 = 21
subtract 28 on both sides
7n= -7
divide by seven on both sides
n= -1
