Step-by-step explanation:
Intercepts of a Line
The x-intercept of a given line is the point where the line crosses the x-axis and the y-intercept of a given line is the point where the line crosses the y-axis.
We are given the following line:
-12x + 18y = 108
To find the x-intercept, we set y=0 and solve for x:
-12x + 18*0 = 108
-12x = 108
x = 108 / (-12) = -9
The x-intercept is the point (-9,0)
To find the y-intercept, we set x=0 and solve for y:
-12*0 + 18y = 108
18y = 108
y = 108 / 18 = 6
The y-intercept is the point (0,6)

On a piece of paper graph f(x) =6 • (0.4)^x. Then determine which answer choice matches the graph you drew
Answer:
The general form of an exponential function is
.... (1)
Where, a is initial value and b is growth or decay factor.
If b>1, then it is an increasing function and if 0<b<1, then it is a decreasing function.
The given function is
.... (2)
From (1) and (2) it is clear that
The value of a is 6. It means the initial value or y-intercept of the function is 6.
The value of b is 0.4, which is less than 1. It means the function is a decreasing function.
Let x be the following values: 1, 2, 3, 4 , 5.
Let f(x) = y.
I will do one only.
Let x = 1
y = 6•(0.4)^(1)
y = 6•(0.4)
y = 2.4

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.
Many pundits claim that the worst is yet to come, with an earthquake 142,990 times
as intense as the 1906 earthquake ready to hit San Francisco. If the pundits ability
to predict such earthquakes were correct, what would be the magnitude of their
claimed earthquake? Round your answer to the nearest tenth.
Answer:
1115322
Step-by-step explanation:
In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.
Claimed statement is he worst is yet to come, with an earthquake 142,990 times as intense as the 1906 earthquake ready to hit San Francisco.
We need to find the magnitude of their claimed earthquake.
It can be calculated by simply multiplying 142,990 by 7.8 as follows :
[tex]E=142990 \times 7.8\\\\=1115322[/tex]
The magnitude of claimed earthquake is 1115322 .
Using the earthquake intensity relation on the Ritcher scale, the magnitude of the claimed earthquake would be 13.0
Uisng the relation :
[tex] M_{a} - M_{b} = log(\frac{I_{a}}{I_{b}}) [/tex] Mb = 7.8Intensity = 142990Substituting the values into the equation :
[tex] M_{a} - 7.8 = log(142990) [/tex]
[tex] M_{a} - 7.8 = 5.1553056 [/tex]
[tex] M_{a}= 5.1553056 + 7.8 [/tex]
[tex] M_{a} = 12.955 [/tex]
Therefore, the magnitude of the claimed earthquake would be 13.0

3. The function E(v)= 15v^2 / 2 models the
kinetic energy E in joules of an object
with a mass of 15 kilograms, where v is
the velocity of the object in meters per
second. Write the inverse function v(E) to
find the velocity of a 15-kilogram object
with kinetic energy E.
Answer:
i think it is 15v (E) = √(2E/m)
Step-by-step explanation:
From the question given:
E = ½mv²
E is the kinetic energy
m is the mass of object
v is the velocity.
To find a model v(E) for the velocity of the object, we simply make V the subject of the above equation.
This can be obtained as follow:
E = ½mv²
Cross multiply
mv² = 2E
Divide both side by m
v² = 2E/m
Take the square root of both side
v = √(2E/m)
Therefore, the model v(E) for the velocity of the object is given by:
v (E) = √(2E/m)
The inverse function v(E) to find the velocity of a 15-kilogram object
with kinetic energy E should be [tex]15v (E) = \sqrt (2E/m)[/tex]
Calculation of the inverse relation:Since we know that
[tex]E = 1\div 2mv^2[/tex]
Here,
E is the kinetic energy
m is the mass of object
v is the velocity.
Now we can write like
[tex]mv^2 = 2E[/tex]
So,
[tex]v^2 = 2E/m[/tex]
Now Take the square root of both side
So,
[tex]v = \sqrt (2E/m)\\\\v (E) = \sqrt (2E/m)[/tex]

In the figure below, m 1 = 3x° and m2 = (x+36).
Find the angle measures
Answer:
Step-by-step explanation:
∠1+∠2=180°
3x+x+36=180
4x=180-36=144
x=144/4=36°
∠1=3x=3×36=108°
∠2=x+36=36+36=72°
The measures of the angles are m∠1 = 108° and m∠2 = 72°.
Given,
m∠1 = 3x°
m∠2 = (x + 36)°
We need to find the measure of these angles.
What is a straight line angle?The straight line angle is 180 degrees.
If the angle is split the sum must be equal to 180 degrees.
We have,
m∠1 = 3x°
m∠2 = (x + 36)°
The figure is at a straight-line angle.
So we have,
m∠1 + m∠2 = 180°
3x° + (x + 36)° = 180
3x + x + 36 = 180
4x + 36 = 180
4x = 180 - 36
4x = 144
x = 144/4
x = 36
Now,
- m∠1
= 3x
= 3 x 36
= 108
- m∠2
= x + 36
= 36 + 36
= 72
Thus the measures of the angles are m∠1 = 108° and m∠2 = 72°.
