Answer:
Answer:
Volume of cylinder =πr²h=π×4²×5=80π m³
=251.2m³
Volume of cuboid=l*b*h=7*3*2=42in³
Volume of cone =(⅓πr²h)+(⅓πr²h)⅓π×(6/2)²(12+8)=60πft³=188.4ft³
Answer:
Step-by-step explanation:
P= 2(L) + 2(w)
1504= 2(525) + 2(w)
1540= 1050 + 2(w)
1540 - 1050= 2(w)
490 = 2(w)
490/2 = w
245 = w
w is y
L is 525
Answer:
18%
Step-by-step explanation:
Express the ending population as a percentage of the starting population:
270000 divided by 330000=0.82
0.82 *100=82
subtract from the 100% we started with to get the percent decrease:
100% - 82% = 18

Answer: Domain (-∞,∞) ; range: (0,∞)
Step-by-step explanation:
1. The exponential functions with the form 
has domain of all real numbers, becaure there is no values in the set of real number for which the value of 
is not define. When approches to ∞, the function approches to ∞.
2. When approches to -∞, the function approches to 0 but never touches it. This means that 
is always greater than zero (
). Therefore, the range of the function is (0,∞).
