In the Logarithm prompt above, note that the value of In x when In x = e to the power -x is x = 1/e.
What is the rationale for the above response?The above assertion is right because the definition of the natural logarithm denoted as In x or ln x, is that it is the inverse function of the exponential function, denoted as e to the power x or ex.
This means that if we have an equation of the form In x = ex, then we can find the value of x by simply taking the inverse of both sides of the equation.
So, if we take the inverse of both sides of the equation In x = ex, we get x = In (ex) = In e to the power x = 1/e.

A rectangular flower garden in Samantha's backyard has 300 feet around its edge. The width of the garden is 70 feet.
Can someone please help me with math.
Answer:
9. C. 35 + 0.12x = 44.36
10. C. The system has no solution since the second equation is equal to 0
11. A. 32
Step-by-step explanation:
9. The Hill family drove for 78 miles
The rental agency chargers a weekend fee of $35.00 and 12 cents per mile
Convert cents to dollars
1 cent = 0.01 dollar
∴, 12 cent = 12 x 0.01 = 0.12 dollar
Therefore, total bill amount = 35 + 0.12 per mile
Let "x" be the number of miles driven
Final bill was $ 44.36
44.36 = 35 + 0.12x
0.12x = 44.36 - 35
0.12x = 9.36
Divide both sides of the equation by 0.12
x = 78

Where m is the slope and b is the y-intercept.
We have,...
On comparing these two lines with slope-intercept form, we get...
Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.
11. This is an equation Solutions: x=32.
⇒ Value of (Dimes + Quarters) = $ 6.70
or, (0.1 m) + 11.5 - 0.25 m = 6.70
-0.15 m = - 4.8
or, m = 4.8/0.15 = 32
⇒ m = 32
A teacher changed to grading from 50 points + 5 for each correct answer to 50 points + 7 for each correct answer. What would change: the slope. The y intercept, both the slope and the y intercept or nothing
Answer:
The slope
Step-by-step explanation:
Given that:
Initial grading ; For each correct answer : 50 points + 5
New grading ; For each correct answer = 50 + 7 points
The reading coukd be expressed in slope intercept form of an equation as :
Initial grading :
y = 50 + 5x
New grading :
y = 50 + 7x
y = total score ; x = number of correct answers
The change in y per unit change in x which is the slope, is the only difference in the two equations, the intercept (50) stays the same.
Therefore, only the slope changes.

The formula for the volume of a rectangular prism is V=l×w×h. Multiply the length times the width times the height to write a simplified expression in standard form to represent the volume of the box.
Answer:
Volume of box= Box Area * Box height
Step-by-step explanation:
If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or
Volume= length * width * height
V= l*w*h
V= l*l*l
V= l³
or if the three sides are not equal this can also be written as
Volume of box= Box length * Box width * Box height
If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as
Volume of box= Box length * Box width * Box height
Volume of box= Box Area * Box height

Graph a direct variation function that goes through the point (-2, -6). what is the slope
Answer:
The slope is 3.
Step-by-step explanation:
A direct variation function will always go through the origin point (0, 0).
Therefore, we have the two points (0, 0) and (-2, -6).
We can use the slope formula to find the slope:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute and evaluate:
[tex]\displaystyle m=\frac{0-(-6)}{0-(-2)}=\frac{6}{2}=3[/tex]
Therefore, the slope of the function is 3.
To graph, simply plot (0, 0) and (-2, -6) and draw a line connecting them. This is shown below.
Answer:
y = 2/3x - 3
Slope: 2/3x
Step-by-step explanation:
Slope: 2/3x
y- intercept: (0,-3)
once it goes down it'll be -2/-3x which will go to through (-2,-6) as soon as it goes down from the y-intercept.
equation: y = 2/3x - 3

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $6500 to rent trucks plus an additional fee of 175.25 for each ton of sugar. The second company charges $5696 to rent trucks plus an additional fee of 225.50 for each ton of sugar.
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Answer:
14 tons
$3,860.50
Step-by-step explanation:
Let x = the amount of sugar transported.
First company:
The cost is $3157 truck rental plus $50.25 per ton of sugar.
Total cost = 3157 + 50.25x dollars
Second company:
There is no charge for truck rental, but it costs $275.75 per ton of sugar.
The total cost is
275.75x
When the two costs are the same, then
275.75x = 3157 +50.25x
225.5x = 3157
x = 14 tons
The total cost is 275.75*14 = $3,860.50

What is m∠B?
A. 38°
B. 42°
C. 48°
D. 128°
Answer:
C m∠B = 48°
Step-by-step explanation:
The acute angles of a right triangle are complementary which means their sum is 90
m∠A + m∠B = 90
42 + m∠B = 90
m∠B = 48°

88 / (? + 32) = (88-56)/32 = 56/?
= 32 / 32 = 56 / ?
1 = 56 / ?
? = 56
88 / (56 +32) = 1 This must be an Isosceles triangle and UT bisects
