The value of the unknown angle x is 22 degrees.
How to find the angle x?SV is a parallel to RU.
RV is a transversal line that cut across the parallel lines SV and RU.
Therefore,
x = ∠V(alternate angles)
Alternate angles are congruent.
Hence,
∠V + 44 + 5x + 4 = 180 (sum of angles in a triangle)
x + 44 + 5x + 4 = 180
x + 5x + 48 = 180
6x + 48 = 180
6x = 180 - 48
6x = 132

Use the appropriate compound interest formula to compute the balance in the account after the stated period of time
$19,000 is invested for 2 years with an APR of 4% and daily compounding.
Compound interest exists as the interest you gain on interest. The balance in the account after 2 years is $42266.
What is meant by compound interest?Compound interest simply refers to the fact that an investment, loan, or bank account's interest accrues exponentially over time as opposed to linearly over time. The word "compound" is crucial here.
'Compound interest' simply indicates earning interest on your savings, and also, eventually, on the interest that those savings earn.
The appropriate formula is
A = P(1 +r/n[tex])^{(nt)[/tex]
where P = 19,000, r = 0.4, n = 365, t = 2.
substitute the values in the above equation, we get
A = 19,000(1 +0.4/365[tex])^{(365 \times2)[/tex]
simplifying the above equation, we get
A = 42266.7592
The balance in the account after 2 years is $42266.

Write the quadratic equation that has roots -1-rt2/3 and -1+rt2/3 if its coefficient with x^2 is equal to 1
[tex]\frac{-1-\sqrt{2}}{3}[/tex] [tex]\frac{-1+\sqrt{2} }{3}[/tex]
The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9
How to determine the quadratic equation?From the question, the given parameters are:
Roots = (-1 - √2)/3 and (-1 + √2)/3
The quadratic equation is then calculated as
f(x) = The products of (x - roots)
Substitute the known values in the above equation
So, we have the following equation
[tex]f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})[/tex]
This gives
[tex]f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})[/tex]
Evaluate the products
[tex]f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})[/tex]
Evaluate the like terms
[tex]f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}[/tex]

Step-by-step explanation:
a.
The mode is the number that appears the most
3 appears once
13 appears once
6 appears twice
8 appears once
10 appears once
5 appears once
Since 6 appears the most, it is the mode in this set of numbers
b.
Again, The mode is the number that appears the most
12 appears once
0 appears once
15 appears twice
13 appears twice
19 appears once
16 appears three times
Since 16 appears the most, it is the mode in this set of numbers
The correct answers are: [A]: "6 " ; and: [B]: " 16 ."
____________________
Step-by-step explanation:
The question asks to find the modes of the following sets of numbers:
Set a) "{3, 13, 6, 8, 10, 5, 6}."
Set b) "{12, 0, 15, 15, 13, 19, 16, 13, 16, 16}."
Note that the mode is the number that occurs most frequently within a data set.
To begin: let's find the mode of Set: a:
_____
First, let's list all the values within Set: a: in order of smallest to largest—to simplify matters:
→ " { 3, 5, 6, 6, 8, 10, 13 }."
In this data set, there is only one value that occurs more than once—
which is 6. As such, the mode of "Data Set: a" is 6 .
Then: To continue: let's find the mode of Set: b:
_____
Second, Let's list all the values within Set: b: in order of smallest to largest—again; to simplify matters:
→ " { 0, 12, 13, 13, 15, 15, 16, 16, 16, 19 } ."
In this data set, we see the following:
Each of the three values: 0, 12, and 19 appear only once;
13 and 15 individually, appear twice; and:
16 appears "three times".
As such:
The value, 16 appears the most in this data set; and:
→ The mode of "Data Set: b"—is 16.

a group of friends is taking part in a two-day walking event for charity. yesterday, they walked 28 miles in 9 hours and 44 minutes. today, they finished the last 10 miles in 2 hours and 55 minutes. what was the group's average speed for the two-day event?
Average speed of the group for the two day event is 0.105 miles\min.
The average is defined as the mean value that is equal to the ratio of the total sum of the number of a given set of values to the total number of values present in that set.
Time taken on day 1 in minutes = 9x60 + 44
= 540 + 44 = 584 minutes.
Time taken on day 2 in minutes = 2x60 + 55
= 120 + 55 = 157 minutes
Now we will be applying speed-distance formula we get,
Speed= Distance/time
On day 1,
[tex]Speed_{1}[/tex]= 28/584 = 0.0479 miles/min
On day 2,
[tex]Speed_{2}[/tex]= 10/175 = 0.0571 miles/min
Thus,the average speed is:
Average = [tex]Speed_{1} + Speed_{2}[/tex] = 0.0479 + 0.0571= 0.105 miles/min
Hence,the average speed is 0.105 miles/min
