The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake
Answer:
The answer is below
Step-by-step explanation:
The Richter scale measures the magnitude, M, of an earthquake as a function of its intensity, I, and the intensity of a reference earthquake, . Which equation could be used to find the intensity of an earthquake with a Richter scale magnitude of 4.8 in reference to an earthquake with an intensity of 1?
Solution:
The Richter magnitude scale was developed in 1935 by Charles F. Richter. The Richter scale is used to measure the strength of earthquakes.
The magnitude of an earthquake (M) using a Richter scale is given by:
[tex]M=log(\frac{I}{I_o} )\\\\Where\ I\ is\ the\ intensity\ of\ the \ earthquake,I_o\ is \ the\ intensity\ of\\the\ reference\ earthquake.\\\\Given\ that\ M=4.8,I_o=1.\ Hence:\\\\4.8=log(\frac{I}{1} )\\\\4.8=log(I)\\\\I=e^{4.8}\\\\I = 121.5[/tex]
Solve for x:
5 + 3x = 8x - 15
Answer:
4 =x
Step-by-step explanation:
5 + 3x = 8x - 15
Subtract 3x from each side
5 + 3x-3x = 8x-3x - 15
5 = 5x -15
Add 15 to each side
5+15 = 5x -15+15
20 = 5x
Divide each side by 5
20/5 = 5x/5
4 =x

What is the length of the diagonal of a 3 by 6 rectangle
Answer:
The diagonal is 6.7082 ≈ 6.71
Step-by-step explanation:
Let the diagonal be x :
To find the diagonal of a 3 by 6 rectangle
We can use the Pythagorean Theorem:
[tex]x^{2} = 3^{2} + 6^{2}[/tex]
⇒ [tex]x^{2} = 9 +36[/tex]
⇒ [tex]x^{2} = 45[/tex]
⇒ [tex]x=\sqrt{45}[/tex]
∴ [tex]x =6.7082[/tex] ≈ [tex]6.71[/tex] (corrected to 2 d.p.)
The solution of the equation3^×=2 is
Answer:
x = log 2 / log 3
x=0.63092
Step-by-step explanation:
3^×=2
Take the log of each side
log 3^×= log2
We know that log a^b = b log a
x log 3 = log 2
Divide each side by log 3
x = log 2 / log 3
x=0.63092
Answer:
x ≈ 0.63093
Step-by-step explanation:
[tex] \small \sf \: 3 {}^{x} = 2[/tex]
Take the log of both side
[tex] \small \sf \: log 3 {}^{x} = log 2[/tex]
Use log a( a ^ x ) = x to simplify the equation
x log 3 = log 2
Divide each side by log 3
x = log 2 / log 3
x ≈ 0.63093

find the value of x and y, (5x-3y, 3x-y) = (16, 12)
Answer:
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>
Step-by-step explanation:
Another way to rewrite (5x-3y, 3x-y) = (16, 12),
5x - 3y = 16 -- (1)
3x - y = 12 -- (2)
Rewriting (1), y = -5/3x - 16/3 -- (1)'
Substituting (1)' into (2),
3x + 5/3x + 16/3 = 12
14/3x = 20/3
x = 10 / 7 -- (3)
Substituting (3) into (2),
3(10/7) - y = 12
30/7 - y = 12
-y = 54 / 7
y = - 54/7-- (4)
Therefore,
x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>
y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

The width, w , of a rectangle is 4 less than 6 times the length, r that would find the area.
Answer:
Width = w
Length = 4w + 6
Area = 130 in2
Area = W X L = 130
So, w X (4w + 6) = 130
4w2 + 6w = 130 by distributing
-130 -130
4w2 + 6w - 130 = 0
Step-by-step explanation:
Answer:
Area = 6L² - 4L
Step-by-step explanation:
Let length be L
Given Width, w is 4 less than 6 times length :
That is ,
6 times length = 6 L
4 less than 6 times length means = 6L - 4
Therefore Length = L
Width = 6L - 4
Area = Length x Width
= L x ( 6L - 4)
= 6L² - 4L

ZA and ZB are complementary angles. If m A = (2x – 13) and m
ZB = (4x - 5), then find the measure of ZB,
Answer:
43º
Step-by-step explanation:
complementary angles total 90
(2x - 13) + (4x - 5) = 90
Combine like terms
6x - 18 = 90
6x = 72
x = 12
ZB = 4x - 5
ZB = 4(12) - 5
ZB = 43º

HOW DO YOU DO THIS I KNOW ITS EASY BUT I FEEL LIKE IM DOING IT WRONG
Answer and Step-by-step explanation:
We're given an isosceles triangle, because it says the two side are congruent. That means the base pairs are congruent as well, meaning the other angle (not x) is 75.
We know that the sum of a triangle's angles is 180, so if we subtract the known angles, we can find x.
180 - 75 - 75 = x
30 = x
So, x = 30.
#teamtrees #PAW (Plant And Water)
We know that a triangles full degree is 180 and we can see that this triangle is symmetrical. So first you add 75 to 75 and get 150, then you subtract 150 from 180 and get 30.
x=30

A ball is thrown from an initial height of 4 feet with an initial upward velocity of 30 feet per second. Find all values of t for which the ball's height is 17 feet.
Answer:
0.43 seconds
Step-by-step explanation:
Given Data
Initial height= 4feet
initial velocity u= 30ft per second
Final height = 17 feet
The distance travelled is the
Final-initial height
=17-4
=13ft
Hence the time taken is calculated using the expression below
Speed= distance/time
30=13/t
t= 13/30
t= 0.43 seconds
Hence the time taken is 0.43 seconds

f(x)=x^2-5 find f(7)
Answer:
44
Step-by-step explanation:
substitute the 7 into the equation for x
f(x) = [tex]x^{2}[/tex] - 5
f(7) = [tex]7^{2}[/tex] - 5
f(7) = 49 - 5
f(7) = 44
Answer:
f(7) = 44
Step-by-step explanation:
To evaluate the function f(x)=x^2-5 at x = 7, replace each instance of 'x' in this function by 7:
f(7) = 7^2 - 5 = 49 - 5 = 44
So: f(7) = 44
The perimeter of the square below is 36 yards. What is the length of each side?
Answer:
A square has all its four sides equal. So the length of one side is equal to the perimeter devided by four
Answer:
9 yards
Step-by-step explanation:
A square has 4 congruent sides
Given the perimeter, the sum of the 4 sides is 36 yards, then
length of side = 36 ÷ 4 = 9 yards

If AGHJ ~ ALMK, with a scale factor of 5:6,
find the perimeter of AGHJ.
Answer:
35
Step-by-step explanation:
Perimeter of LMK = 14 + 11 + 17
Perimeter of LMK = 42
Perimeter GHJ/ Perimeter LMK = 5/6
Perimeter GHJ / 42 = 5/ 6 Cross Multiply
6*Perimeter GHJ = 42 * 5
6*Perimeter GHJ = 210 Divide by 6
Perimeter GHJ = 210/6
Perimeter GHJ = 35
The diagram shows squares 1,2, and 3 constructed on the sides of a right triangle. Which statement about the squares must be true?
Answer:
Option D.
Step-by-step explanation:
Remember the Pythagorean theorem.
For a triangle rectangle of catheti A and B, and hypotenuse H, we have:
A^2 + B^2 = H^2
Now, also remember that for a square of sidelength L the area is:
area = L^2
First, you can see that square 1 has a side length equal to one of the catheti, and the same for square 2. While square 3 has a side lenght equal to the hypotenuse of the triangle.
If we define:
A = length of the smaller cathetus
then the area of square 1 is:
A^2
B = length of the larger cathetus.
The area of square 2 is then:
B^2
H as the length of the hypotenuse:
The area of square 3 is:
H^2
And by Pythagorean theorem we know that:
A^2 + B^2 = H^2
We can replace these by:
area of square 1 + area of square 2 = area of square 3.
Then the correct option is D.
