Answer:
The time of oil tanker will be 80 sec.
Explanation:
Given that,
He walks at 3 km/hour.
If the container ship is 100 m long, and travelling at 12 km/hour.
The distance will be 200 m.
We need to calculate the relative velocity
Using formula of relative velocity
Put the value into the formula
The distance is 200 m.
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time of oil tanker will be 80 sec.
Answer:
Carbon atoms
Explanation:
Mass no. of an element= no. of protons + no. of neutrons = 6 + 7 = 13
Atomic no. = no. of protons/electrons = 6
There is an unbalanced situation between the neutron no and proton no. so this has to be an isotope of Carbon-12, and this element is Carbon-13.
Answer: D [-1,1]
is the inverse of function g(x).
the inverse equation of g(x) = sin(x):
sin(y) = x
y = 
(x)
using a trig circle with radius 1, we can find out that the max values of sin(x) are 1 and -1, so the domain of the inverse of sin(x) must be [-1,1]
**Note: if allowed during AP test, test from school. or assignment, you can use your graphing calculator to graph (x)
Answer:
C
Explanation:
"Vouchers in higher education do not improve our public schools and colleges, because experiments show us that education vouchers divert much-needed public funds for the few and have weakened the entire system."
Answer:
<em></em>
- <em>There are 30 experimental units in the experiment, which are the 30: the thirty sheets of metal.</em>
Explanation:
This table shows you how the <em>experimental</em> units, <em>sheets of metal</em>, were treated:
Metal 1 Metal 2 Metal 3 Total
Paint A 5 5 5 15
Paint B 5 5 5 15
Total 10 10 10 30
Fifteen sheets (units) were treated with <em>paint A</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
Fifteen sheets (units) were treated with <em>paint B</em>: 5 of metal 1, 5 of metal 2, and 5 of metal 3.
