Answer:
Relative Size, S, is 1584.89
Step-by-step explanation:
The equation is 
Where,
- R is the measurement in Richter Scale
- S is the relative size of the earthquare
<u>It is given that in Richter Scale, an earthquake measured 3.2, so
.</u>
<em>They want to know relative size, S, so we put given information in equation and solve for S:</em>

<em>Converting to exponential form, we have:</em>

<em>Rounding to nearest hundredth, we have:</em>

Answer:
40
Step-by-step explanation:
*this is a 90 degree triangle
so we will use Pythagorean theorem to get X
hypotenuse²=side of right triangle²+the other side of right triangle²
so
50²=30²+x²
2500=900+X²
2500-900=x²
1600=x²
x=√1600
=40
so the answer is 40
Answer:
Option a, 13
if you solve it, you get 13 as the answer
³√(5x-1)=4
or, 5x-1=64
or, 5x=65
or, x=13
Hi...
Ans for the Question 8.
the reflecting line is on the y intercept itself and is perpendicular.
Only the x intercept will change if any other points were reflected over the same line. Since the line is on the y intercept then the only the sign of x will change.
so the answer for 8 is option A
Answer:
7x^2 - 7x + 6
Step-by-step explanation:
<em>Rearrange equation so its easier</em>
-2x^2 + 9x^2 - 8x + x +3 + 3
<em>Then simplify</em>
7x^2 - 7x + 6
