Answer:
2.2 miles
Step-by-step explanation:
3 hours and 30 minutes minus 2 hours and 15 minutes is 1 hour and 15 minutes. 2/40 gives you 0.05. 1.15 - 0.05 gives you 1 hour and 10 minutes and multiply that by 2 and it gives you 2.2 miles.
The distance between Terrence’s house from the theater will be 2.4 miles.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. Distance is defined as the length between the two points.
Let us suppose the following parameters to get the distance.
D = distance of Terrence’s house from the theater
v₁ = speed at which Terrence walks from home to the theater = 2 mi/h
t₁ = time taken by Terrence to walk from home to the theater = D/v₁ = D/2
v₂ = speed at which Terrence returns back to home = 40 mi/h
t₂ = time taken by Terrence to return back to home = D/v₂ = D/40
t' = time spent in watching the movie = 2 h 15 min = 2.25 h
t = total time = 3.5 h
The distance will be calculated as given below:-
t = t₁ + t₂ + t'
3.5 = (D/2) + (D/40) + 2.25
D = 2.4 miles

[tex]\huge\boxed{ \text{(A)}\ \ \frac{1}{10}, -\frac{1}{10}}[/tex]
Step-by-step explanation:
We can simplify this expression down so that we have x isolated on one side of the equation.
So we can take the square root of both sides.
[tex]x = \sqrt{\frac{1}{100}}[/tex]
The square root of [tex]\frac{1}{100}[/tex] will be the number that, when multiplied by itself, will get us [tex]\frac{1}{100}[/tex].
In order to find the square root of a fraction, the numerator squared must correct and the denominator squared must be correct.
[tex]1^2 = 1[/tex]
[tex]10^2 = 100[/tex]
This means that we have the values 1 and 10. Therefore one of our fractions is [tex]\frac{1}{10}[/tex].
HOWEVER: A negative number squared is a positive. So this also works:
[tex]-1^2 = 1\\\\-10^2=10[/tex]
So we have [tex]-\frac{1}{10}[/tex] along with [tex]\frac{1}{10}[/tex].

Determine the remaining sides and angles of the triangle ABC.
A. 18.95 degree.
B. 0.56 degree.
C. 17.83 m.
Answer:
Angle C ∠C = 160.49°
side b = 0.522 m
side a = 17.34 m
Step-by-step explanation:
Given that;
In a Δ ABC,
∠A = 18.95°
∠B = 0.56°
∠C = ???
side A = ???
side B = ???
side C = 17.83 m
We are to determine the unknown missing sides and the angle.
We know that, the sum of angles in a triangle = 180°
∴
∠A + ∠B + ∠C = 180°
18.95° + 0.56° + ∠C = 180°
∠C = 180° - 18.95° - 0.56°
∠C = 160.49°
Using sine rule to determine the unknown sides. The sine rule can be expressed as:
[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]
To determine side b, we have:
[tex]\mathtt{ \dfrac{sin \ B}{b} = \dfrac{sin \ C}{c} }[/tex]
[tex]\mathtt{ \dfrac{sin \ 0.56^0}{b} = \dfrac{sin \ 160.49}{17.83} }[/tex]
[tex]\mathtt{ b (sin \ 160.49) = 17.83 (sin \ 0.56)}[/tex]
[tex]\mathtt{ b = \dfrac{17.83 (sin \ 0.56)}{(sin \ 160.49)}}[/tex]
[tex]\mathtt{ b = \dfrac{17.83 \times 0.0097737}{0.33397}}[/tex]
[tex]\mathtt{ b = \dfrac{0.174265071}{0.33397}}[/tex]
b = 0.522 m
For side a, we have
[tex]\mathtt{\dfrac{sin \ A}{a} = \dfrac{sin \ B}{b} }[/tex]
[tex]\mathtt{\dfrac{sin \ 18.95}{a} = \dfrac{sin \ 0.56}{0.522} }[/tex]
[tex]\mathtt{a \times sin \ 0.56 = 0.522 (sin \ 18.95)}[/tex]
[tex]\mathtt{a = \dfrac{0.522 (sin \ 18.95)}{ sin \ 0.56}}[/tex]
[tex]\mathtt{a = \dfrac{0.522\times 0.3247 }{ 0.0097737}}[/tex]
a = 17.34 m
A stable roommate problem with 4 students a, b, c, d is defined as follows. Each student ranks the other three in strict order of preference. A matching is defined as the separation of the students into two disjoint pairs. A matching is stable if no two separated students prefer each other to their current roommates. Does a stable matching always exist
Answer:
Each student ranks the other three in strict order of preference.
Step-by-step explanation:
When 4 different students from different background and personality lives together, there seems to be a room for the problems and stability between them. When the problem of stability arises, it would be as a result of the other 3 students ranking each other in strict order of preference regarding to their relationship and association.

Given f(x)=13(4−x)2, what is the value of f(16)?
Answer:
1872
Step-by-step explanation:
Plug is 16 for x
f(x)=13(4−x)^2
f(16)=13(4−16)^2
f(16)=13(-12)^2
-12^2=144
f(16)=13(144)
f(16)=1872
Hope this helps! Plz award Brainliest : )
The value of function f(x)= 13(4 - x)² at x= 16 is 1872.
To find the value of f(16), we substitute x = 16 into the expression for f(x) and evaluate it.
f(x) = 13(4 - x)²
Substituting x = 16:
f(16) = 13(4 - 16)²
Now, let's calculate:
f(16) = 13(-12)²
= 13(144)
= 1872
Therefore, the value of f(16) is 1872.

Show the conjecture is false by finding a counterexample.
m If m does not equal -1, then < 1.
Dividing any positive number m over (m+1) leads to a positive result that is smaller than one. This is because the denominator is larger than the numerator.
However, if m is negative, then it's a different story. Consider m = -2
If m = -2, then m+1 = -2+1 = -1
Meaning that [tex]\frac{m}{m+1} = \frac{-2}{-1} = 2[/tex] but this result is not less than 1
So m = -2 is one counterexample of infinitely many to show that [tex]\frac{m}{m+1} < 1, \text{ with } m \ne -1[/tex] is not always true. If you restricted m to be positive, then the inequality would be true.

Apply Exponent Rule: [tex]\bold{\:a^{-b}=\frac{1}{a^b}}[/tex]
[tex]\bold{3^{-5}: \ \frac{1}{3^5} }[/tex]
The equivalent expression for [tex]3^{-5[/tex] using exponent is [tex]\( \dfrac{1}{3^5} \)[/tex].
Explanation:
When we have a negative exponent, it indicates the reciprocal of the base raised to the positive exponent.
In this case, [tex]3^{-5[/tex] means the reciprocal of [tex]3^5[/tex].
To compute [tex]\( 3^5 \)[/tex] raise 3 to the power of 5, which gives us
[tex]\( 3^5 = 3 \times 3 \times 3 \times 3 \times 3 = 243 \)[/tex]
Now, to get the reciprocal of 243,
simply take [tex]\( \dfrac{1}{243} \)[/tex], which is the same as [tex]\( \dfrac{1}{3^5} \)[/tex].
So, [tex]\( 3^{-5} = \dfrac{1}{3^5} = \dfrac{1}{243} \)[/tex].

WILL MARK BRAINLISIT
Answer:
x=60
Step-by-step explanation:
here DOB and AOC are vertically opposite angles and the values of them are equal. so lets take the two angles as y.
x+DOB is 90(because EOA is 90 and the sum of angles in a straight line is 180), DOB is y and can write a equation as x+y=90
and 30+2x+y = 180 ,
2x+y=150, (180-30)
then two equations can be made.
x+y=90
2x+y=150
simplifying these two simultaneous equations
can get x as 60. and 2x is 120.
The value of x is 60°
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.
Here, DOB and AOC have equal values and are at vertically opposed angles. Let's use y to represent the two angles.
Since EOA is 90 and the total of the angles in a straight line is 180, x+DOB equals 90 and can be written as x+y=90.
And 30 + 2x + y = 180 ,
⇒ 2x+y = 180-30
⇒ 2x + y = 150,
After which two equations can be created.
⇒ x+y=90
⇒ 2x+y=150
We have the two simultaneous equations made simpler.
We can get x as 60. and 2x as 120.
Thus, the value of x is 60°
