The Domain will be the values "x" takes on... ok... notice the graph, horizontally starts off at x = -2 and keeps on going to +∞, so hmm that's the domain.
Answer:
90 mph
Step-by-step explanation:
Average speed is given by
Average speed=(initial+final speed)/2
Given average speed of 60 mph then considering initial speed of 30 mph. Let x be the final speed hence
60=(30+x)/2
120=30+x
X=120-30=90 mph
Therefore, the return trip speed is 90 mph
D=rt
Divide the t from both sides
D/t=rt/t
The ts on the right will cancel each other out leaving
D/t=r
Answer:Undefined
Step-by-step explanation:
The formula for the volume of a cone is V=(1/3)πr^2h. Plugging in what you know, you get (1/18)π=(1/3)π(1/3)^2(h). The radius is half the diameter 2/3 so it is 1/3. Simplifying, you get (1/18)π=(1/3)π(1/9)(h) which is (1/18)π=(1/27)π(h). Dividing both sides by (1/27)π, you get h=1.5ft.
