Math on the Spot An elevator is rising at a constant rate of 10 feet per second. Its height in feet after t seconds is given by h = 10t. At the instant the elevator is at
ground level, a ball is thrown upward with an initial velocity of 60 feet per second from
ground level. The height in feet of the ball after t seconds is given by h= - 16t² + 60t.
Find the time it takes for the ball and the elevator to reach the same height.

1 is c

2 is a

3 is a

step-by-step explanation:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
