Answer:
A. y = 3x; 30 feet
Step-by-step explanation:
The person travels 75 feet in 25 seconds, meaning that he will travel 3 feet per second.
75/25 = 3
This means that the equation will be y = 3x. To find the the feet traveled after 10 seconds, plug 10 into the given equation and solve for y.
y = 3x
y = 3(10)
y = 30
The person will travel 30 feet.
We have two classrooms and seven packages.
This means we need to divide the seven packages in half (two pieces).
7packages ÷ 2 classrooms = 7/2 = 3.5 packages per class
(three and a half packages)
Step-by-step explanation:
the formula to calculate number of terms in GP is : TN=a×r^n-1
First we multiply 2r*r and it gives us
.
Then -5r, + 20r = 15r
Then -5*10 gives us -50.
So the answer is:
According to the graph, the displacement goes from a maximum position of 14 at time 0.75 to a minimum of -14 at time 2.25 s, hence the maximum displacement is:
14 + 14 = 28 units
14 positive side, 14 negative side.
