Answer:

  d.  about 50 times larger

Step-by-step explanation:

The given expressions for magnitude (M) can be solved for the intensity (I). Then the ratio of intensities is ...

  \dfrac{I_2}{I_1}=\dfrac{I_0\cdot 10^{M_2}}{I_0\cdot 10^{M_1}}=10^{M_2-M_1}=10^{4.2-2.5}\\\\=10^{1.7}\approx 50

The larger earthquake had about 50 times the intensity of the smaller one.

Find the equation of the line (-4,-7) and (12,1)
ryzh [129]

Answer:

y = 1/2x -5  slope intercept form

y-1 = 1/2(x-12)  point slope form

Step-by-step explanation:

We can find the slope of this line by using

m = (y2-y1/(x2-x1)

  = (1--7)/ (12 --4)

 = (1+7)/(12+4)

 = 8/16

  = 1/2

We know the slope and a point, so we can use point slope form

y-y1 = m(x-x1)

y-1 = 1/2(x-12)

y-1 = 1/2 x -6

Add 1 to each side

y-1+1 = 1/2x -6+1

y = 1/2x -5

This is in slope intercept form

Nikolay [14]
  • The that indicates the height is AB
  • The letter that indicates the radius is CB
  • The letter indicates the diameter is CD
  • The letter indicates the vertex is A

<h3>What is a cone ?</h3>

A cone can be regarded as a three-dimensional shape which has a vertex at the top of it.

Considering a cone as described in the question, we could see that the distance from point A to B will gives us the height which is the vertical length.

Therefore, Vertex is at the top of the cone which is point A.

A turtle is 20 5/6 inches below the surface of a pond. It dives to a depth of 32 1/4 inches. What was the change in the turtles
Lana71 [14]
Alrite, so their change is just their difference, namely 32 1/4 - 20 5/6.

let's change those to "improper" fractions first.

\bf 20\frac{5}{6}\implies \cfrac{20\cdot 6+5}{6}\implies \cfrac{125}{6}&#10;\\\\\\&#10;32\frac{1}{4}\implies \cfrac{32\cdot 4+1}{4}\implies \cfrac{129}{4}\impliedby \textit{let's use an LCD of \underline{12}}\\\\&#10;-------------------------------\\\\

\bf \cfrac{129}{4}-\cfrac{125}{6}\implies \cfrac{(3\cdot 129)+(2\cdot 125)}{12}\implies \cfrac{387-250}{12}\implies \cfrac{137}{12}&#10;\\\\\\&#10;\textit{hmmm 12 goes into 137, 11 times, thus}\quad \boxed{11\frac{5}{12}}&#10;\\\\\\&#10;\textit{because}\qquad \cfrac{11\cdot 12+5}{12}\implies \cfrac{132+5}{12}\implies \cfrac{137}{12}
