Answer:
It is -1.602 x 10^-19 C, and the smallest unit of charge
Step-by-step explanation:
The charge on an electron is . The charge on electron is negative. The quantization of electric charge is :
q = ne
q is net charge
n is no of electrons
e is the electronic charge which is . Hence, the correct option is (b).
Answer:
The frequency of f(x) is two times the frequency of the parent function.
Step-by-step explanation:
We can say that the number that is beside the x is equal to , where f is the frequency.
Then, for the parent function, we get:
or solving for :
At the same way, for f(x), we get:
But is equal to
, so we can write the last equation as:
It means that the frequency of f(x) is two times the frequency of the parent function.
Answer:
1st problem: b)
2nd problem: c)
Step-by-step explanation:
1st problem:
The formula/equation you want to use is:
where
t=number of years
A=amount he will owe in t years
P=principal (initial amount)
r=rate
n=number of times the interest is compounded per year t.
We are given:
P=2500
r=12%=.12
n=12 (since there are 12 months in a year and the interest is being compounded per month)
Time to clean up the inside of the ( ).
----------------------------------------------------
2nd Problem:
Compounded continuously problems use base as e.
P is still the principal
r is still the rate
t is still the number of years
A is still the amount.
You are given:
P=2500
r=12%=.12
Let's plug that information in:
.
Answer:
64
Step-by-step explanation:
Euclide's theorem states that in a right triangle, the square built of the side lenght is equivalent of the rectangle with sides hypotenuse and projection of the same side lenght. In formula, given the measures on the triangle:
