Volume of cylinder = π.R².h , where R = radius and h = height
Let's replace h by 2h:
V₁= πR².(2h) → V₁ = 2π.R².h
Now let's double R, the radius (and keep h as h)
V₂ = π.(2R)².h → V₂ = 4.π.R².h
Compare V₁ to V₂→ (V₁ = 2π.R².h and V₂ = 4.π.R².h).
It's obvious that V₂ = 2.V₁
Step-by-step explanation:
I am not sure but i think it is D or E (last 2 choices)
Sorry if wrong
Answer: 93 and 4/5
Step-by-step explanation:
6 7/10 divided by 1/14
= 67/10 divided by 1/14
= 67/10 x 14/1
= 67/5 x 7/1
= 469/5
Answer:
d. Variable ratio
Step-by-step explanation:
We are asked to determine that gambling at a slot machine is an example of which reinforcement schedule.
Let us see our given choices one by one.
a. Fixed ratio
We know that in fixed ratio schedule, reinforcement is delivered after the completion of a number of responses. An example of fixed ratio is a reward to every 6th response.
b. Fixed interval
We know that in fixed interval schedule the first response is rewarded only after a specified amount of time has elapsed. An example of fixed interval schedule is weekly paycheck.
c. Variable interval
We know that in variable interval schedule, the reinforcement is delivered at changing and unpredictable intervals of time.
d. Variable ratio
In variable ratio schedule, a response is reinforced after an unpredictable number of responses. Gambling and lottery are examples of variable ratio.
Therefore, option 'd' is the correct choice.
Answer:
(3rd listed choice) Paula's notes are incorrect. Step 4a should be "If the result does not define y as a function of x, then f does not have an inverse," and step 4b should be "If the result defines y as a function of x, then f has an inverse."
Step-by-step explanation:
If f(y) = x can be solved for a relation for y that is a function, then f(x) has an inverse. It will be the function defined by y.
