Suppose that n is a positive number and Log10 n = q. Which expression always equals the value of Log10 n^2?
Slav-nsk [51]

<u>2q</u>

Answer:

solution given:

log_{10} n=q

now

Log_{10 }n^2=?

by using property of logarithms

log_{a} n^p=p log_{a}n

now

Log_{10 }n^2=2 Log_{10 }n

=2q

since log_{10} n=q

Geomotry 10th grade easy 25 points
Dimas [21]

Answer: <em>1=60°</em>

Step-by-step explanation:

<em>First, let's take our given angle of 30°</em>

<em>30° is in a right triangle, so the angles must be 90°, 60°, and 30°</em>

<em>Now the angle that is 45° makes angle 1 congruent to angle 60°</em>

<em>Meaning angle 1 is </em><em>60°</em>

1-cos2a/1+cosa if 1/3 how much sin²a
Helen [10]

Answer:

(1-cos2A) /(1+cos2A) =tan²A

Proof:

We know that,

cos(A+B) =cosA.cosB-sinA.sinB

=>cos2A=cos(A+A)

=>cos2A=cosA.cosA - sinA.sinA

=>cos2A=cos²A-sin²A

=>cos2A=(cos²A-sin²A)/(cos²A+sin²A

Since {cos²A+sin²A=1}

Divide the numerator & the denominator by (cos²A) to get,

cos2A = {(cos²A-sin²A) ÷cos²A} / {(cos²A+sin²A) ÷cos²A}

cos2A ={(1-tan²A)/(1+tan²A)}

Then,

1-cos2A = 1-[{(1–tan²A)/(1+tan²A)}]

1-cos2A =(1+tan²A-1+tan²A)/(1+tan²A)

1-cos2A=(2tan²A)/(1+tan²A)

And now.......

1+cos2A=1+[{(1-tan²A)/(1+tan²A)}]

1+cos2A={1+tan²A+1-tan²A}/{1+tan²A}

1+cos2A=2/(1+tan²A)

So now,

(1-cos2A)/(1+cos2A)= {2tan²A/(1+tan²A)}÷{2/(1+tan²A)}

={(2tan²A)(1+tan²A)}÷{2(1+tan²A)}

=tan²A
