Mathematics

SCORPION-xisa [38]3 years ago
7 0

Answer:

a=15849*a_{o}

Step-by-step explanation:

The Richter scale is a logarithmic scale

\log_{10}\left( \frac{a}{a_{o}} \right)=4.9\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=10^{4.9}\\\left( \frac{a}{a_{o}} \right)=15,849\\{a}=15,849*{a_{o}}

I NEEEDDDD HELPPP ASAPPPP!!! it’s urgentttttt
Artist 52 [7]

Answer:

(x + 14)² + (y – 21/2)² = 1

Step-by-step explanation:

The equation of a circle can be written as seen below

(x – h)² + (y – k)² = r²

Where (h,k) is at the center and r = radius

We are given that the radius is 1

We are also given that the center is at (-14,21/2)

So we know that r = 1, h = -14, and k = 21/2

So to find the equation of the circle we simply substitute these values into the equation of a circle

Equation of a circle: (x – h)² + (y – k)² = r²

r = 1, h = -14, and k = 21/2

Substitute values

(x – (-14))² + (y – 21/2)² = 1²

1^2 = 1

The two negative signs before the 14 cancel out and it changes to + 14

The equation of a circle with a center at (-14,21/2) and a radius of 1 is (x + 14)² + (y – 21/2)² = 1
