Answer:
65.9734457254 or 65.97
Step-by-step explanation:
c= pi x diameter
c= pi x (10.5 x 2)
c= pi x 21
= 65.9734457254
Answer: A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
Step-by-step explanation:
Remember, a quadratic function which has roots x = a, and x = b, can be written as:
p(x) = A*(x - a)*(x - b)
Where A is the leading coefficient. This is the factorized form of a quadratic.
We have the function:
f(x) = (x - 3)^2
Now, we could rewrite this as:
f(x) = (x - 3)*(x - 3) = 1*(x - 3)*(x - 3)
Then we wrote f(x) in its factorized form, from this, we can see that the roots of the function are x = 3, and x = 3 (we have the same root two times)
Then the only root of f(x) is x = 3.
Remember that a root (also called a zero) is the value of x where the function intersects the x-axis. then the correct option here is:
A) The only zero of the function is 3 which is where the graph of the function intersects the x-axis
Answer:
13,415 miles
Step-by-step explanation:
Final position - initial position = Miles traveled:
23,840 miles - 10,425 miles = 13,415 miles
Answer:
The heaviest baby have to gain to reach a healthy level by 42 ounces.
Step-by-step explanation:
It is said that the 500-gram babies are going to have to make four times their weight [to reach a healthy level].
So, the healthy level of weight is (500 × 4) = 2000 gm i.e. 2 kg.
Now, 1 kg is equivalent to 35.274 ounces.
So, 2 kg will be equivalent to (35.274 × 2) = 70.548 ounces.
So, the heaviest baby with weight 28.6 ounces have to gain weight to reach a healthy level by (70.548 - 28.6) = 41.948 ounces ≈ 42 ounces. (Answer)
Answer:
0.02
Step-by-step explanation:
Pack A and B both consisted of 52 cards. When shuffled, 51 cards in A and 53 cards in deck B. It appears that the Top card of A left with only 51 possible cards to be taken from A (since we know the Queen hadn't moved).
The two possible cases are: probability of not taking King of Hearts (from A to B), and the other were we did.
Let K= the event of taking the King of Hearts from A to B and be 
the occasion being the top card of B.
