What is the square root 3175 by division method
Vedmedyk [2.9K]

56.347..........

just simply put the value 3175 under division root and make pairs of 31 and 75.Now think of a number whose square will be nearest to 31 and that ll be 5.Now write 5 in the quotient and 5 also 5 under the divider.Now by multiplying 5 with the 5 in the quotient you ll get 25 write this under 31.And by adding 5 in the divider 5 youll get 10.write this under the divider.no by subtracting 25 from 31 you ll get 6 and by bringing 75 down it ll be 675.Now think of a number again and write it with 10.Like 6 into 6 is 36 and when you multiply 6 with 106 you ll get nearest number to 675 that ll be 636.Now because its giving a remainder just add a .0 in the question and continue to solve it the same way.And as it ll be a continuous answer so just add continuty dots........ or just round it off to nearest whole number

Write the expression in terms of sine and cosine, and then simplify so that no quotients appear in the final expression. sec bet
Ede4ka [16]

Answer:

E

Step-by-step explanation:

The expression given is:  sec β - cos β ( i will write "beta" instead of the symbol β)

<em>We know that sec(x)=\frac{1}{cos(x)}</em>

<em>Substituting this into the the expression and doing some algebra manipulation, we have:</em>

sec(beta)-cos(beta)\\=\frac{1}{cos(beta)}-cos(beta)\\=\frac{1-cos^{2}(beta)}{cos(beta)}

<em>Using the identity  cos^{2}(x)+sin^{2}(x)=1\\ (also sin^{2}(x)=1-cos^{2}(x)), we can now write:</em>

\frac{1-cos^{2}(beta)}{cos(beta)}\\=\frac{sin^2(beta)}{cos(beta)}\\=\frac{sin(beta)*sin(beta)}{cos(beta)}\\=\frac{sin(beta)}{cos(beta)}*sin(beta)

<em>We know tan(x)=\frac{sin(x)}{cos(x)}, substituting this, we have:</em>

\frac{sin(beta)}{cos(beta)}*sin(beta)\\=tan(beta)*sin(beta)


Answer choice E is the right answer.
