for P(t) = 65- 5t
domain is [0, 13]
because intially at t = 0 total puppy available is 65 (put t = 0 in equation)
now after 13 days
P(t) = 65 - 5×13 = 65-65 = 0
no puppy available. so t has last range of 13.
similarly for second its domain is [0, ∞]
as subscribers will increase as t will increase.
for 3rd
C(t) = 65 + 5t
here t is guest so . they can only accomdate 30 guests only so t csn go to 30 only.
so domain is [0,30]
Answer:
a) 0.6435 radians
b) 80.1 feet/sec
Step-by-step explanation:
a) 75 = (50²/16)sin(theta)cos(theta)
sin(theta)cos(theta) = 0.48
2sin(theta)cos(theta) = 0.96
sin(2theta) = 0.96
2theta = 1.287002218
Theta = 0.6435011088 radians
b) 200 = (v²/16)sin(0.75)cos(0.75)
6416.072347 = v²
v = 80.10038918 feet/sec
Sum of one-sided angles is 180°
Sum of two adjacent supplementary angles = 180 .
Answer: x=3 and y = 5.
