Michael has a free throw record of .625. If he has to shoot 50 baskets, how many can we expect him to make?
1 answer:
Answer:
The number of free shoot to be make is 80 .
Step-by-step explanation:
Given as :
The free throw record of Michael = x = 0.625
The number of basket to be shoot = n = 50 baskets
Let The number of free shoot to be make = y
<u>Now, according to question</u>
The number of free shoot be make =
i.e y =
or, y =
∴ y = 80
So, The number of free shoot to be make = y = 80
Hence,The number of free shoot to be make is 80 . Answer

Answer:
D and F
Step-by-step explanation:
can be rewritten as
.
From there you can use the quadratic formula (ignore the A, I can‘t seem to remove it), where a=1, b=4, and c=-8.
Then you get
Then you get
So
Which means or
which are choices D and F.
The positions when the particle reverses direction are:
The acceleraton of the paticle when reverses direction is:
Why?
To solve the problem, we need to remember that if we derivate the position function, we will get the velocity function, and if we derivate the velocity function, we will get the acceleration function. So, we will need to derivate two times.
Also, when the particle reverses its direction, the velocity is equal to 0.
We are given the following function:
So,
- Derivating to get the velocity function, we have:
Now, making the function equal to 0, to find the times when the particle reversed its direction, we have:
We know that the particle reversed its direction two times.
- Derivating the velocity function to find the acceleration function, we have:
Now, substituting the times to calculate the accelerations, we have:
Now, substitutitng the times to calculate the positions, we have:
