Brums [2.3K]

Answer: 1/2

$\lim_{x \to 1}\frac{1+cos \pi x}{tan^{2}\pi x }\\\\ = \lim_{x \to 1} \frac{1+cos\pi x}{\frac{sin^{2}\pi x }{cos^{2}\pi x } } \\\\\\= \lim_{x \to 1}\frac{cos^{2}\pi x(1+cos\pi x) }{sin^{2}\pi x } \\\\\\= \lim_{x \to 1} \frac{cos^{2}\pi x(1+cos\pi x)}{1-cos^{2}\pi x } \\\\= \lim_{x \to 1} \frac{cos^{2}\pi x }{1-cos\pi x} \\\\= \lim_{x \to 1}\frac{cos^{2}\pi .1 }{1-cos\pi .1}\\\\= \lim_{x \to 1}\frac{1}{1-(-1)}\\\\=\frac{1}{2}$

Consider the original parallelogram and the enlargement. A parallelogram has side lengths 5 millimeters and 10 millimeters. A la

konstantin123 [22]

Answer:

B=30mm

Step-by-step explanation:

According to the Question,

we have, A parallelogram that has one side(A) 5 millimeters and the other side(C) 10 millimeters. A larger parallelogram has side one side(D) 15 millimeters.

The Enlargement Parallelogram And Original Parallelogram Sides Ratio Remain the same.

Therefore, A/C = D/B

5/10 = 15/B

B=150/5

B=30mm

TiliK225 [7]

To find number of years we take LCM of planets revolution times.

Planet's revolution times are given in the chart

Solar System Planet Revolution Time

Earth 1 year

Mars 2 years

Jupiter 12 years

Saturn 30 years

Uranus 84 years

Neptune 165 years

We take LCM of 1,2,12,30,84 and 165

Prime factorization of 2 = 2

Prime factorization of 12 = 2^2 * 3

Prime factorization of 30 = 2 * 3* 5

Prime factorization of 84 = 2^2 * 3 * 7

Prime factorization of 165 = 3*5*11

We take set of prime factors that has highest exponent,

So LCM = 2^2 * 3 * 5 * 7 * 11 = 4620

Therefore it will take 4620 years.
