Answer:
The domain of the function is 0 less-than-or-equal-to x less-than infinity ⇒ 3rd answer
Step-by-step explanation:
The domain of the function f(x) = y is all the values of x which make the function defined
∵
- There is no square root for negative number, that means x
must be non-negative number
∵ The non negative numbers start from zero till infinity
∴ 0 ≤ x < ∞
∴ x must be greater than or equal zero and less than infinity
- Values of x are the domain of the function
∴ The domain of the function is 0 ≤ x < ∞
The domain of the function is 0 less-than-or-equal-to x less-than infinity
Answer:
$1210
Step-by-step explanation:
Let x be total amount
First John spent $110 on a radio and 4/11 of what was left on presents for his friends so he was left with
Then he put 2/5 of his remaining money into a checking account
Rest he donated to charity
Hence total amount of money John originally had was $1210
From the equation of motion, we know,
Where s= displacement
u= initial velocity
a= gravitational force
t= time
Displacement is 0 since the ball comes back to the same point from where it was thrown.
A = since the ball is thrown upwards.
Plug the known values into the equation.
=>
Solving for u gives :
u= 16.67 m/ sec ....... equation (1)
At maximum height, final velocity i.e v is 0
Time take to reach the top =
=>
Solving for s we get
s= 14.16 m
