96x+23=265 solve for x
ANSWER- X is 2.52083333 or 2.52083 rounded
265-23 is 242. 242 divided into 96 is 2.52083333
(96 x 2.52083333)+23 = 265
This means our X is 2.52083...

Step-by-step explanation:
An earthquake of magnitude 9.1 occurred in 2004 in the Indian Ocean near Indonesia. It was about 74,900 times as strong as the greatest earthquake ever to hit Texas. Find the magnitude of the Texas earthquake. (Remember that an increase of 1.0 on the Richter scale means an earthquake is 30 times stronger.)
b. How does the solution of your equation help you find the magnitude?
The Magnitude of earthquake that hit Texas is 5.8; With the help of the logarithmic equation so found, we can get the value of M, with which we can get the magnitude of the Texas earthquake.
What is Logarithm?The opposite of exponentiation is the logarithm.This indicates that the exponent to which a fixed number, base b, must be raised in order to obtain a specific number x, is represented by the logarithm of that number.A number's natural logarithm is its logarithm to the base of the transcendental and irrational number e, which is roughly equivalent to 2.718281828459.Given:
Magnitude of earthquake that hit Indian Ocean = 9.1 [tex]I_1[/tex] = Intensity of weaker earthquake[tex]I_2[/tex] = Intensity of greater earthquake.To find: Magnitude of earthquake that hit Texas.
Finding:
From the given, [tex]\frac{I_2}{I_1}[/tex] gives the ratio of the greater earthquake's intensity to the weaker earthquake's intensity.This ratio, when written as an exponential equation, equals [tex]30^M[/tex] where M is the increase in magnitude difference:=> [tex]\frac{I_2}{I_1}[/tex] = [tex]30^M[/tex]
For [tex]\frac{I_2}{I_1}[/tex] = 74900, the above expression becomes:
=> 74900 = [tex]30^M[/tex]
Taking logarithm on both sides, with base 10 gives:
=> log (74900) = log ([tex]30^M[/tex])
As [tex]log_b(a)^m = m(log_b(a))[/tex],
=> log (74900) = M ( log (30))
=> [tex]\frac{log(74900)}{log (30)}[/tex] = M
=> M ≈ 3.3, i.e., the increase in magnitude difference is approximately 3.3.
Thus, the magnitude of the earthquake that hit Texas = 9.1 - 3.3 = 5.8.
The logarithmic equation, in terms of exponents, so formed is: 74900 = [tex]30^M[/tex]. By finding the solution of this equation, we get the value of M, which gives us the value of the increase in the magnitude of the earthquakes.With the help of this value so found, we can find the required value of the magnitude of earthquake in Texas, as we already know that of Indian Ocean, by basic algebra.To learn more about logarithms, refer to the link: brainly.com/question/25710806

Question Write a quadratic function in standard form whose graph has the given characteristics. vertex: (1,\ 9) ; passes through (4,\ 6)
The quadratic function of graph given characteristics vertex(1,\9); passes through (4,\6) is y=1/3x2+2/3x+26/3.
A quadratic function is a polynomial function with one or more variables where the highest exponent of the variable is two. Due to the fact that the biggest degree term in a quadratic function is of second degree, it is sometimes referred to as the polynomial of degree 2. There must be a quadratic function with at least one second-degree term. It performs algebraic operations.
Assum:y=ax2+bx+c
Point (1,9)(4,6) into it:{9=a+b+c/6=16a+4b+c} (point 1and 2)
Therefore, vertex(1,9) –b/2a=1→-b=2a
Point 3 into 1 and 2={9=-a+c/b=8a+c}
a=1/3, b=2/3, c=26/3
y=1/3x2+2/3x+26/3
For: y=ax2+bx+c
The graph intersects the x axis at x1 and x2,
X1= -b+√b2-4ac/2a , X2= -b-√b2-4ac/2a
The x-coordinate of the vertex must be in the middle of x1 and x2.
Assume the x-coordinate of the vertex as x
So : x=x1+x2/2 = -b+√b2-4ac/2a + -b-√b2-4ac/2a / 2 = -b/2a

The length of a rectangle is 4 meters less than twice the width. If the area of the rectangle is 286 square meters, find the Dimensions.
Answer:
The dimensions of the rectangle are length = 22 meters and width = 13 meters.
Step-by-step explanation:
It is given that the length of a rectangle is 4 meters less than twice the width and if the area of the rectangle is 286 square meters we need to calculate the dimensions.
Firstly, let us look at the dimensions of the rectangle;
=> Let 'l' be the length and 'b' be the width of the rectangle.
Now, let us look at the area of a rectangle;
=> l × b
So, we get an equation from the above condition;
=> l = 2b - 4
Now, the area of the rectangle is given that is 286 square meters;
=> A = 286 sq. m.
Using the above-mentioned formula for the area of the rectangle we get;
=> A = l × b
=> 286 = (2b - 4) × b
=> 286 = 2b² - 4b
=> 2b² - 4b - 286 = 0
After solving it further we get;
=> 2b² - 4b - 286 = 0
=> b² - 2b - 143 = 0
=> b² - 13b + 11b - 143 = 0
=> (b - 13) + (b + 11) = 0
Now, after equating both the sides we get;
=> (b - 13) = 0
=> b = 13
and
=> (b + 11) = 0
=> b = -11
But, b = -11 is not possible so, the width of the rectangle is 13 meters.
And the length of the rectangle would be,
=> l = 2b - 4
=> l = 2 × 13 - 4
=> l = 22
Therefore, the dimensions of the rectangle are length = 22 meters and width = 13 meters.

The unknown angle in the triangle is as follows:
m∠A = 52°
How to find the angle in a triangle?External angle theorem states that If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.
Therefore,
m∠D = m∠A + m∠B
m∠D = 116°
m∠A = (2x)°
m∠B = (x + 38)°
Hence,
116 = 2x + x + 38
116 = 3x + 38
3x = 116 - 38
3x = 78
divide both sides by 3
x = 78 / 3
x = 26

What is the slope of the line that passes through the points (8, 0) and (-4, -8)
The slope of the line that passes through (8, 0) and (-4, -8) is calculated as: m = 2/3.
How to Calculate the Slope of a Line that Passes through two Points?The slope (m) formula is given as:
Slope (m) = change in y/change in x = y2 - y1/x2 - x1.
Given the following points on the line:
(8, 0) = (x1, y1)
(-4, -8) = (x2, y2)
Plug in the values into the slope formula, x = y2 - y1/x2 - x1:
Slope (m) of the line = (-8 - 0) / (-4 - 8)
Slope (m) of the line = (-8) / (-12)
Slope (m) of the line = 2/3

Evaluate each logarithm.
log 10,000
The value of the expression log 10,000 is 4.
The logarithmic function is the inverse of the exponential function. This means that the logarithm of a given number, say x, is the exponent to which another fixed number that is the base b, must be raised, so as to produce that number x.
Log a to the base b can be written as- log a/ log b.
Moreover, log [tex]a^{k}[/tex] = k log a, for all non negative values of a
Here, we are given a logarithmic expression- log 10,000
As the base is not given, we always assume it to be 10.
We can expand this as-
log 10,000 = log 10,000/ log 10
= log [tex]10^{4}[/tex]/ log 10
= 4 log 10/ log 10
