Answer:
Distance traveled by hockey puck of second player is 40 feet more than that of first player.
Step-by-step explanation:
Maximum height of 3 feet is attained by the hockey puck of first player is when the puck is 55 feet away from the player.
It is at the mid point of the total horizontal distance to be traveled by the hockey puck.
So, the horizontal distance traveled by hockey puck of first player = 55 + 55 = 110 feet
Second player:
where is the height of a second hockey puck
is the horizontal distance.
When the puck hits the ground,
Now, let us find the value of .
At feet or feet,
Therefore, the distance traveled by second hockey puck is 150 feet.
So, the answer is:
<em>Distance traveled by hockey puck of second player is 40 feet more than that of first player.</em>

Answer:
It will be quadrupled
Step-by-step explanation:
we know that
All spheres are similar
so
The ratio of the surface areas of two spheres is equal to the scale factor squared
Let
z ----> the scale factor
x ----> surface area of the sphere with radius doubled
y ----> surface area of the original sphere
so
The scale factor is 2 (because the radius of the sphere will be doubled)
substitute
so
The new surface area is 4 times the original surface area
therefore
The surface area will be quadrupled
Answer:
C. 30
Step-by-step explanation:
We have a list of names that need to be sorted in a specific order. For this, we will use a permutation. This can be found on a scientific calculator, however, I'll be using the equation.
n = total number of objects
r = number of objects selected
In this instance, n will equal 6 since we have 6 different names to choose from and r will equal 2 since we are picking two names. Enter the values into the equation and evaluate.
Therefore, there are 30 possible two-part names.
