The answer is:
[B]: -4 .
_____________________________Here is the problem:
_____________________ "Find f(3)."
_______________________ f(x) =

;
______________________________________
Since we are asked to find: " f(3)" ; we consider the number, "3", which is GREATER THAN OR EQUAL TO "-2" ; (that is, " 3

-2" ;
and f(x) = -4 if x

-2 .
_____________________________________________________So, in this case, f(x) = f(3) = -4 ; which is: "Answer choice: [B] ".

Answer:

Step-by-step explanation:
There are many methods to find the vertex of a quadratic function. The method that I will show you is by using the roots of the function
In the case of this function, the roots are
..
The vertex of a function will always be directly between these roots. The number that is directly between -1 and -3 is -2. This means that the x-value of our vertex is -2.
Now that we have the x-value, we can plug this into the function in order to get our y-value.

We have found that our y-value is -2. This means that the coordinates of the vertex are 
Answer:
option F
Step-by-step explanation:
given,
capacity of tank = 1000 gallon
volume of water leak = 300 gallon
time = 30 min
water is leaking at the rate
formula used

At t = 0 A = 1000 gallons

B = 1000

at t = 30 A = 700


taking ln both side


now,



hence, the correct answer is option F

Answer:
C) 1/4
Step-by-step explanation:
Because you have six-sided dice there are 3 odd numbers and 3 even numbers. That means you have a 1/2 for getting either a odd or even number. So we would add 1/2 + 1/2 because you are rolling two times and both have a 1/2 of getting either a odd or even number. 1/2+1/2 = 1./4 which would be your answer.
Hope this helped! Have a good day/night and good luck! Stay safe!!
