Answer:
(-9/8, 1/36)
Step-by-step explanation:
Midpoint Formula: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]
Step 1: Find midpoint x
x = (1/4 + -5/2)/2
x = (-9/4)/2
x = -9/8
Step 2: Find midpoint y
y = (-4/9 + 1/2)/2
y = (1/18)/2
y = 1/36
Step 3: Write midpoint coordinates

Use Theorem 9.11 to determine the convergence or divergence of the p-series. 1 + 1/32 squareroot + 1/243 squareroot 3 + 1/1024 squareroot 4 + 1/3125 squareroot 5 + p = ______
converges
diverges
Answer:
Diverges
Step-by-step explanation:
since the value of P = 5/6 < 1 the p-series diverges
summation of 1/n^5/6 at n = 1 and infinity
attached below is the detailed solution using Theorem 9.11 to determine the convergence or divergence of the p-series
The value of the p in the p-series is less than one. Then the p-series is a divergence.
What is p-series?It is an infinite type of series.
The p-series is given below.
[tex]1 + \dfrac{1}{\sqrt[6]{32} } +\dfrac{1}{\sqrt[6]{243} }+\dfrac{1}{\sqrt[6]{1024} }+\dfrac{1}{\sqrt[6]{3125} }[/tex]
The series can be written as
[tex]\dfrac{1}{1^{5/6}}+\dfrac{1}{2^{5/6}}+\dfrac{1}{3^{5/6}}+\dfrac{1}{4^{5/6}}+\dfrac{1}{5^{5/6}}[/tex]
Then the sum will be
[tex]\rm \Rightarrow \Sigma _{n=0} ^{\infty} \dfrac{1}{n^{5/6}} \\\\\\\Rightarrow P = \dfrac{5}{6} < 1[/tex]
Since the value of the p is <1. Then the series is divergence.

Payton leaves to go on an 85 minute bike ride at 3:27 p.m.Payton's family eats dinner at 5:45 p.m How much time will Payton have between finishing her bike ride and eating dinner?
He starts to ride at 3:27 p.m.
85 minutes -> hours = 1 h 25 minutes (85/60 = 1 with 25 of rest)
3:27 + 1 h 25 min = h. 4:52
between 4:52 and 5:45 =>
5 hours 45 min - 4 hours 52 minutes =
4h 105 min ( 1h = 60min ) - 4h 52 min =
0h 53min
Payton has 53 minutes
Answer:
53 minutes
Step-by-step explanation:
Payton leaves at 3:27 p.m. and rides for 85 minutes. When she has finished, the time will be 3:27 + 0:85, or
3:27 + 1:25, since 1 hr = 60 min
4:52 p.m.
Dinner will be at 5:45 p.m. That means Payton will have (5:45 - 4:52) hours until dinner: Borrowing 60 minutes from 5:45, we get
4:105 - 4:52 = 0:53. That's 53 minutes to while away before dinner.
Let un be the nth Fibonacci number. Prove that the Euclidean algorithm takes precisely n steps to prove that gcd(un+1, un) = 1.
Hello, Please consider the following.
Fibonacci numbers are defined as
[tex]u_0=1\\\\u_1=1\\\\u_{n+2}=u_{n+1}+u_{n} \ for \ n\geq 0[/tex]
Step 1 - The proposition is true for n = 1
[tex]GCD(u_2,u_1) ?\\[/tex]
Let's apply Euclidean algorithm
[tex]u_1=1, u_2=2\\\\u_2=2\times u_1+0 = 2 \times 1 +0[/tex]
This is exactly 1 step and [tex]GCD(u_2,u_1) =1[/tex]
Step 2 - We assume that this is true for k, meaning that the Euclidean algorithm takes precisely k steps to prove that [tex]GCD(u_{k+1},u_{k})=1[/tex]
[tex]u_{k+2}=u_{k+1}+u_k \ and \ 0 < u_k < u_{k+1}[/tex]
So, the first step of the algorithm is
[tex]u_{k+2}=u_{k+1}\times 1 +u_{k}[/tex]
And from now, we need to find [tex]GCD(u_{k+1},u_k)[/tex] which is 1 and takes k steps, by induction Hypothesis. Therefore, it takes k + 1 steps to find [tex]GCD(u_{k+2},u_{k+1})=1[/tex]
Step 3 - Conclusion
We have just proved that the Euclidean algorithm takes precisely n steps to prove that [tex]GCD(u_{n+1},u_{n})=1[/tex]

PLEASEEEEE HELPP<333
Answer:
58
Step-by-step explanation:
We can use the Pythagorean theorem to find the area of the square for the third side.
The equation for the Pythagorean theorem is
a^2 + b^2 = c^2
where a and b are the lengths of the two legs of the triangle, and c is the length of the hypotenuse.
a^2 + b^2 = c^2
3^2+7^2=x^2
9+49=x^2
58=x^2
The area of the square for the third side of the triangle is 58 units^2 squared.

36/9 = 4
Janine did 4 times as many as Craig
Answer:
4 times
Step-by-step explanation:
Because 36 divided by 9 = 4

12. A shipment of TV sets, some weighing 30 kg each and the other weighing 50 kg each, has a total weight of 220 kg. If there
are 20 TV sets all together, how many weigh 50 kg and how many weigh 30 kg?
A. 6 weigh 50 kg and 14 weigh 30
B. 15 weigh 50 kg and 5 weigh 30.
C. 2 weigh 50 kg and 18 weigh 30
D. 14 weigh 50 kg and 6 weigh 30
E. 4 weigh 50 kg and 16 weigh 30
F. 11 weigh 50 kg and 9 weigh 30
Answer:
D
Step-by-step explanation:
Let a be the number of TV sets that weight 30 kg and let b be the number of TV sets that weigh 50 kg.
So, all together, they have a total weight of 880. In other words:
[tex]30a+50b=880[/tex]
And, there are 20 TV sets all together. Thus:
[tex]a+b=20[/tex]
This is a system of equations. Solve by substitution. Subtract b from both sides in the second equation:
[tex]a+b=20\\a=20-b[/tex]
Substitute this into the first:
[tex]30a+50b=880\\30(20-b)+50b=880[/tex]
Distribute:
[tex]600-30b+50b=880[/tex]
Subtract 600 from both sides:
[tex]-30b+50b=280[/tex]
Combine like terms:
[tex]20b=280[/tex]
Divide both sides by 20:
[tex]b=14[/tex]
So, there are 14 TV sets that weight 50 kg.
Plug this in for the second equation to solve for a:
[tex]a+b=20[/tex]
Plug in 14 for b:
[tex]a+14=20[/tex]
Subtract 14 from both sides:
[tex]a=6[/tex]
Therefore, there are 6 TV sets that weigh 30 kg and 14 TV sets that weigh 50 kg.
Our answer is D :)
Step-by-step explanation:
Total number of T..V sets we have 20
Let x be the number of T.V sets that weigh 30 kg and y be the no. of sets that weigh 50 kg
When we add all we get a total of 880
[tex]\blue\star[/tex] 30a + 50b = 880
It is given to us that
[tex]\blue\star[/tex]a + b = 20. eq 1
[tex]\blue\star[/tex]a = 20-b
Put the value of a in ist equation we get,
[tex]\blue\star[/tex]30(20-b) + 50b =880
[tex]\blue\star[/tex]600 - 30b+50b = 880
[tex]\blue\star[/tex]600 + 20b = 880
[tex]\blue\star[/tex]20b = 280
[tex]\blue\star[/tex] b = 14
so there are 14 T.V sets that weigh 50 kg
put it in eq 1 we get
[tex]\blue\star[/tex] a + b =20
[tex]\blue\star[/tex]a + 14 = 20
[tex]\blue\star[/tex]a = 6

n ΔABC, AB = 10 and BC = 5. Which expression is always true? A. 5 < AC < 10 B. AC = 5 C. 5 < AC < 15 D. AC = 10
Answer:
A. 5 < AC < 10
Step-by-step explanation:
We are given the ∆ABC
To solve for the sides of ∆ABC , we make use of Pythagoras Theorem
Pythagoras Theorem states that:
AB² = AC² + BC²
Where AB = Longest side, hence its length is always more that AC and BC.
In the above Question, we are given the values of AB and BC
AB = 10
BC = 5
Inputting these values into the Pythagoras Theorem,
10² = AC² + 5²
100 = AC² + 25
AC² = 100 - 25
AC² = 75
AC = √75
AC = 8.6602540378
According to the above calculation, we can see that the expression that is always true = Option A "5 < AC < 10"

Can you multiply it all out? Yes. Did you need to? No. That was just to prove that the first choice is correct.
All you have to know to answer this is that:
positive * positive = positive; + * + = +
negative * negative = negative; - * - = +
positive * negative (or negative * positive; remember that the order of the numbers you're multiplying does not matter) = negative; + * - = - or - * + = -
Or if you learn better in words:
If two factors have the same sign, the answer is positive.
If two factors have different signs, like if one is positive and the other is negative, then the answer is negative.

Jessica takes 4 business trips a month for x months in a row. Write an expression to show how many business trips Jessica has taken.
Answer:
[tex] t = 4x [/tex]
Step-by-step explanation:
We are given that in 1 month, Jessica takes 4 business trips. Take 4 as our coefficient or constant.
Let t be the total number of business trips Jessica has taken.
For 1 month, 4 trips are taken.
For x months, total business trips taken will be expressed as,
[tex] t = 4x [/tex]
Let's say for example, we have 5 months in a row, i.e. x = 5. Total business trips taken by Jessica can be gotten by simply plugging in the value of x.
[tex] t = 4(5) = 20 trips [/tex]
In 5 months in a row, Jessica takes 20 business trips.

Evaluate: [(- 16) + 4] ÷ [(-2) + 5]
Answer:
We need to evaluate this: [(-16)+4] / [(-2)+5]
First, we do the brackets:
[(-16)+4][(-2)+5][(-16)+4] = -16 + 4 = -12
[(-2) + 5] = -2 + 5 = 3
Now, we only need to divide, as we have calculated both brackets:
-12/3 = -4
(Remember that when dividing a negative number by a positive one, we always obtain a negative)
So the result is -4

Annie is running a trail that is 4 1/2 miles long. She ran the first 2/3 of the distance. Then the trail became very steep, so she slowed down to a walk. Annie walked for 1/2 of the remaining distance and then ran again for the rest of the way. How far did Annie walk? Write the answer as a simplified fraction.
Answer:
Annie walked 1 11/12 miles
Step-by-step explanation:
Trail= 4 1/2 miles
Annie ran the first 2/3 miles
Remaining miles= Total miles - Miles covered first
= 4 1/2 - 2/3
= 9/2 - 2/3
= 27-4 / 6
= 23/6 miles
Remaining miles = 23/6 miles
Annie walked for 1/2 of the remaining distance
1/2 of the remaining miles= 1/2 × 23/6
=23 / 12
= 1 11/12
Annie walked 1 11/12 miles
