Answer:
B on the first question and A on the 2nd
Step-by-step explanation:
V(t) = dy/dt = 40 - 32t
ai). average velocity = (v(0.5) - v(0))/(0.5 - 0) = ((40 - 32(0.5)) - (40 - 32(0)))/0.5 = (40 - 16 - 40)/0.5 = -16/0.5 = -32m / s
ii). average velocity = (v(0.1) - v(0))/(0.1 - 0) = ((40 - 32(0.1)) - (40 - 32(0)))/0.1 = (40 - 3.2 - 40)/0.1 = -3.2/0.1 = -32m / s
iii). average velocity = (v(0.05) - v(0))/(0.05 - 0) = ((40 - 32(0.05)) - (40 - 32(0)))/0.05 = (40 - 1.6 - 40)/0.05 = -1.6/0.05 = -32m / s
Answer:
B. 8 x 10^3
Step-by-step explanation:
1.6 x 10^5 / 0.2 x 10^2
= 160 000 / 20
= 8 000
You can write this as 8 x 10^3

Find total number of integers
----------------------------------------------------------------------------
Number of integers from 1 to 100 = 100
There are 100 numbers altogether
----------------------------------------------------------------------------
Find total numbers that can be divided by 2
----------------------------------------------------------------------------
Number that are multiples of 2 = 100 ÷ 2 = 50
50 of the number are multiples of 2
----------------------------------------------------------------------------
Find total numbers that are multiples of 3
----------------------------------------------------------------------------
Numbers that are multiples of 3 = 100 ÷ 3 = 33 R 1
33 of the numbers are multiples of 3
Of the 33 numbers that are multiples of 3, half of the numbers are even and had been included in multiples of 2.
33 ÷ 2 = 16 R 1
33 - 16 = 17
17 of the numbers are multiples of 3
----------------------------------------------------------------------------
Total numbers that can be multiples of 2 or 3
----------------------------------------------------------------------------
50 + 17 = 67
----------------------------------------------------------------------------
Total number that are neither multiples of 2 nor 3
----------------------------------------------------------------------------
100 - 67 = 33
----------------------------------------------------------------------------
Ans: 33 integers are neither multiples of 2 nor multiples 3
----------------------------------------------------------------------------
