Which steps can be used to verify that tan(w + Pi) = tan(w)? Rewrite tan(w + Pi) as tan(w) + tan(Pi). Then simplify the expression using tan(Pi) = 1. Rewrite tan(w + Pi) as tan(w) + tan(Pi). Then simplify the expression using tan(Pi) = 0. Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 1. Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.
Answer:
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
Step-by-step explanation:
According to tangent sub identity
Tan(A+B) = TanA+TanB/1-tanAtanB
Applying this in question
Tan(w+Pi) = tan(w)+tan(pi)/1-tan(w)tan(pi)
According to trig identity, tan(pi) = 0
Substitute
Tan(w+Pi) = tan(w)+0/1-tan(w)(0)
Tan(w+Pi) = tan(w)/1
Tan(w+Pi) = tan(w) (proved!)
Hence the correct option is
Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0
The given expression can be prove by using tangent sub-identity. In the solution we will use [tex]\tan (A+B)[/tex] sub-identity.
The correct option is Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.
Given:
The given expression is as follows,
[tex]\tan(w+\pi)=\tan(w)[/tex]
Write the tangent sub-identity.
[tex]\tan(A+B)=\dfrac{\tan A+\tan B}{1-\tan A\tan B}[/tex]
Now replace [tex]A[/tex] with [tex]w[/tex] and [tex]B[/tex] with [tex]\pi[/tex].
[tex]\tan(w+\pi)=\dfrac{\tan w+\tan \pi}{1-\tan w\tan \pi}[/tex]
Substitute 0 for [tex]\tan \pi[/tex].
[tex]\tan(w+\pi)=\dfrac{\tan w+0}{1-\tan w\times 0}\\\tan(w+\pi)=\tan w[/tex]
Thus, the correct option is Rewrite tan(w + Pi) using the tangent sum identity. Then simplify the resulting expression using tan(Pi) = 0.

The number A8 is a two-digit number with a digit A and units (ones) digit 8.
Similarly, 3B is a two-digit number with tens digit 3 and units digit B.
When A8 is multiplied by 3B, the result is the four digit number 0730. That is,
A8
x 3B
C730
If A, B, and C are each different digits from 0 to 9, determine the values of A.
B. and C.
Answer:
A = 7
B = 5
C = 2
Step-by-step explanation:
We are given;
A8 × 3B = C730
Now, by inspection, in multiplication of the above, the product of 8 and B must produce a number whose unit digit is 0.
Thus,the only two single digit numbers that can fit this description for B is either 5 or 0 since if they would yield a unit digit of 0 when multiplied by8.
Now, let's test 0.
If B is 0, it means the unit digit of C730 is 0 as wanted while the remaining product of A8 and 3 should yield C73. Now product of A8 and 3 would produce a number with a last digit of 4. But our last digit there in C73 is 3. Thus, it means B cannot be 0 but is 5.
Thus, it means 3B is 35.
Now, we are told that A, B and C could be any single digit number.
from 0 - 9.
Thus, the maximum value of A is 9.
Let's try to put 9 for A and multiply by 35.
If A is 9,then 98 × 35 = 3430
It means that the maximum value of C is 3.
Thus, C can either be 3 or less than 3. So, C is either 1, 2, or 3
Now, if C = 1, it means the C730 is now 1730.
Thus,A8 will be: 1730/35 = 49.43
This is a decimal and thus, it means C ≠ 1.
Now,if C = 2, it means the C730 is now 2730.
Thus,A8 will be: 2730/35 = 78
This is a whole number and thus, it means C = 2
Now,if C = 3, it means the C730 is now 3730.
Thus,A8 will be: 3730/35 = 106.57
This is a decimal and thus, it means C ≠ 3
Thus; A8 is 78 when C = 2
So, A = 7

Step-by-step explanation:
i looked a the calculator
Answer:
trust me on this answer. It is D, a = 1, b = 2, c = 3
Step-by-step explanation:
Okay, so the problem is 5/8 divided by 3/8.
So, you find the reciprocal, which then is 5/8 x 8/3
Since there is an 8 is both the first denominator and the second numerator, you cross them out, which leaves you 5/3
So, 5 can go into 3, only 1 time.
5/3 = 3/3 + 2/3
So, 3/3 + 2/3 = 1 2/3
Therefore, D is the answer of choice.

The following pieces of empirical evidence have been collected over the years: Historical trend data show an increase in temperature globally Levels of carbon dioxide gas are on the rise Levels of methane gas are on the rise Glacial ice is melting Antarctic and Artic sea ice is melting Which statement best explains the significance of this empirical evidence?
a
It provides a hypothesis for the climate of the past.
b
It provides data for science journals and textbooks.
c
It supports the scientific explanation for global warming.
d
It predicts future weather patterns.
Answer:
C. It supports the scientific explanation for global warming.
Explanation:
The listed pieces of empirical evidence support the scientific explanation for global warming. Global warming is the long-term heating of Earth's climate, and the increase in levels of carbon dioxide and methane is the reason why glacial ice in the Antarctic and Arctic sea is melting.
These pieces of evidence don't deal with the past of the future. They tell us what is going on right now. Based on them, we could make an assumption about what is going to happen in the future, but there are no predictions here.
Also, this data can be used for science journals and textbooks, but that purpose is not expressed here.
This leaves us with option C as the correct one.

You are offered the following gamble:
Flip two fair coins. If at least one head comes up, you win $12. If not, you lose $24. What is the expected value of this gamble?
Answer:
$3
Step-by-step explanation:
Flipping two fair coins :
Sample space :
{TH, HT, TT, HH}
Atleast one head = 12
If not = - 24
Probability of atleast one head = 3/4
If not ; probability of 2 tails = 1/4
Hence,
X ______12 ______ -24
P(x) ___0.75 ______0.25
Expected value for of gamble E(x) :
Σx * p(x) = (12 * 0.75) + (-24 * 0.25)
E(x) = 9 - 6
E(x) = 3
Expected value of gamble = $3

Step-by-step explanation:
At first we assume that examination occured in 2020. The decay of radioactive isotopes are represented by the following ordinary differential equation:
[tex]\frac{dm}{dt} = -\frac{m}{\tau}[/tex] (Eq. 1)
Where:
[tex]\frac{dm}{dt}[/tex] - First derivative of mass in time, measured in miligrams per year.
[tex]\tau[/tex] - Time constant, measured in years.
[tex]m[/tex] - Mass of the radioactive isotope, measured in miligrams.
Now we obtain the solution of this differential equation:
[tex]\int {\frac{dm}{m} } = -\frac{1}{\tau}\int dt[/tex]
[tex]\ln m = -\frac{1}{\tau} + C[/tex]
[tex]m(t) = m_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (Eq. 2)
Where:
[tex]m_{o}[/tex] - Initial mass of isotope, measured in miligrams.
[tex]t[/tex] - Time, measured in years.
And time is cleared within the equation:
[tex]t = -\tau \cdot \ln \left[\frac{m(t)}{m_{o}} \right][/tex]
Then, time constant can be found as a function of half-life:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (Eq. 3)
If we know that [tex]t_{1/2} = 5730\,yr[/tex] and [tex]\frac{m(t)}{m_{o}} = 0.35[/tex], then:
[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]
[tex]\tau \approx 8266.643\,yr[/tex]
[tex]t = -(8266.643\,yr)\cdot \ln 0.35[/tex]
[tex]t \approx 8678.505\,yr[/tex]
