The ball will hit the ground between 8 and 9 seconds
If this is correct the answer would be
y^2 + 0.1y + 0.0025
Answer:
7
Step-by-step explanation:
We want to find the number 4-digit of positive integers n such that removing the thousands digit divides the number by 9.
__
Let the thousands digit be 'd'. Then we want to find the integer solutions to ...
n -1000d = n/9
n -n/9 = 1000d . . . . . . add 1000d -n/9
8n = 9000d . . . . . . . . multiply by 9
n = 1125d . . . . . . . . . divide by 8
The values of d that will give a suitable 4-digit value of n are 1 through 7.
When d=8, n is 9000. Removing the 9 gives 0, not 1000.
When d=9, n is 10125, not a 4-digit number.
There are 7 4-digit numbers such that removing the thousands digit gives 1/9 of the number.
Answer:
The seat no of a plane is 2
Answer:
-4/8
Step-by-step explanation:
slope=rise/run
y2-y1/x2-x1
(-2,3) (6, -1)
x1 y1)( x2 y2
-1 - 3= (-4)
6-(-2)
6+2=8
m/slope= -4/8
