Need help ASAP please!!! The formula determines the magnitude of an earthquake, where I is the intensity of the earthquake and S

is the intensity of a “standard earthquake.” How many times stronger is an earthquake with a magnitude of 8 than an earthquake with a magnitude of 6? Show your work.

Answer:

100

Step-by-step explanation:

M = log(I/S)

The intensity of the first earthquake:

8 = log(I₁/S)

10⁸ = I₁/S

I₁ = 10⁸ S

The intensity of the second earthquake:

6 = log(I₂/S)

10⁶ = I₂/S

I₂ = 10⁶ S

The ratio is:

I₁/I₂ = (10⁸ S) / (10⁶ S)

I₁/I₂ = 100

It is 100 times stronger.

Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
soldier1979 [14.2K]

Answer:

y-5 = -6(x+3) OR y = -6x-13

Step-by-step explanation:

Let's use slope-intercept form to solve this problem.

Slope intercept form is the following:

y-y1 = m(x-x1)

x1 and y1 are given by the point in the problem.

x1 = -3, y1 = 5.

m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,

m = -6.

If we plug these values into the equation for slope intercept form, we get the following:

y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)

This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.

y-5 = -6x-18

y = -6x-13

What is the radius of a circle whose equation is x^2 + y^2 + 8x - 6y + 21 =0
sveta [45]
Hello,

x^2+y^2+8x-6y+21=0

Rewritten in the form of a standard circle equation:

(x-(-4))^2+(y-3)^2=2^2

Therefore, the circle properties are:

(a,b)=(-4,3),r=2

The radius of the circle whose equation is <span>x^2 + y^2 + 8x - 6y + 21 =0 is 2.

What substitution Should be used to re-write 26(x^3+1)^2-22(x^3+1)-3=0 as a quadratic function?
mel-nik [20]

Answer:

x^3+1

Step-by-step explanation:

26(x^3+1)^2-22(x^3+1)-3=0

Comparing to

A(u)^2+B(u)+C =0

Where A,B,C are constants

You should see that we need to substitute the x^3+1 with u.
