A sand dune stands 5 feet above sea level. The hill is eroding at a rate of 1 foot per 20 years. Let y represent the height of t
he sand dune after x years. Which equation represents the situation?
2 answers:
Answer:
y=-1/20x+5
Step-by-step explanation:
The situation will be represented by linear equation, this is given by:
y=ax+b
where:
a=slope=rate
b=y-intercept
from our situation:
a=-1/20
b=5 ft
thus the equation modeling the situation will be:
y=-1/20x+5
Answer: y=-1/20x+5

R = 3cm
V = 900 cm^3
V = pi * r^2 * h / 3
900 = (22/7) * 3^2 * h/3
h = (900*3*7) / 22 / 3^2
h = 18900 / 22 / 9
h = 95.45 cm

You would do 21kgx2.2lb=46.2lb, which means the stand couldn't support a 21kg television because it is over 40 pounds.
Answer:
99
Step-by-step explanation:
P(3) = 1-0.88 = 0.12
P(3 or 4) = 0.12 + 0.21 = 0.33
Expected no. = no
= 300(0.33) = 99
I believe the equation is wrong
