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)

In the figure below, m 1 = 3x° and m2 = (x+36).
Find the angle measures
Answers
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°.

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.
Answers
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]

On a piece of paper graph f(x) =6 • (0.4)^x. Then determine which answer choice matches the graph you drew
Answers
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
Your first point is (1, 2.4).
Do the rest in like manner. Then graph each point on the xy-plane and lastly connect each point with a smooth curve.
