Answer:
39 km due southStep-by-step explanation:
Since the two vector have opposite directions, their sum will be the difference of magnitudes:
r + s = 164 - 125 = 39And the direction is the same with the vector with greater magnitude, so it is south.
Answer:
Magnitude = 39 km
Direction = South
Step-by-step explanation:
Formula we use,
→ r + s
Now the required answer will be,
→ r + s
→ 164 + (-125)
→ 164 - 125
→ 39 km
Thus, answer is 39 km due south.

1. Which of the following numbers has factors that
include the smallest factor (other than 1) of 111?
A. 15
B. 22
C. 28
D. 40
The smallest factor (other than 1) of 111 would be 15.
Option (A) is correct.
What is the smallest factor of a number other than 1?
A number can have a maximum of one factor, and only one has that many factors. Every other number has more than one factor.
Prime numbers have two factors, for example, 2,3,5,7,11...,2729...,2927, 9999959999, and so on. Prime numbers have only one factor the number itself.
The factors of 111 are 1, 3, 37, and 111.
for option (A), the factors of 15 are 1, 3, 5, and 15.
for option (B), the factors of 22 are 1, 2, 11, and 22.
for option (C), the factors of 28 are 1, 2, 4, 7, 14, and 28.
for option (D), the factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
So if you observe all the options, the smallest factor (other than 1) of 111 would be 15.
Hence, the smallest factor (other than 1) of 111 would be 15.

x divided by 12; x= 2/3
Answer:
1/18
Step-by-step explanation:
Since x=2/3, we can plug in 2/3 for x, and we have 2/3 divided by 12.
Based on what we know about fractions, we can say that dividing by 12 is the same as multiplying by 1/12.
Therefore, we have the expression 2/3*1/12.
Next, we get 2/36, which can be simplified into 1/18.

What is linear equation ? A linear equation, a first-order polynomial, that is, H. The sum of a series of terms, each of which is the product of a constant and a variable to the first power, equals the constant. In particular, linear equations in n variables have the form a0 + a1x1 + ... + anxn = c. where x1,...,xn are variables, coefficients a0,...,an are constants, and c is a constant. With multiple variables, the equation may be linear in some variables and non-linear in others. So the equation x + y = 3 is linear in both x and y, but x + y2 = 0 is linear in x but not in y. An equation of two linear variables represents a straight line in Cartesian coordinates. If the constant term c = 0, the line passes through the origin. A linear equation is an algebraic equation of the form y=mx+b. The above is sometimes called a "linear equation in two variables" where y and x are variables.Calculationx value would be the time in months and y value would be the loan amount that is left.
The y-intercept is basically the point where x is 0. So, we can say the y-intercept would be when time is 0.
That's basically when the loan started and the y-value represents the full loan amount., which is $22,000.
correct option is third option -- "the original amount of the loan".

Step-by-step explanation:
slope formula: y2-y1/x2-x1

y-16/36
Numerator is supposed to equal -32 since denominator is 36
y-16=-32
+16. +16
y=-16
Hopes this helps,please mark brainliest
Answer:
(b) -16
Step-by-step explanation:
You want the y-value that goes with x=17 on the line with slope -8/9 through point (-19, 16).
Point-slope equationThe point-slope form of the equation for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
The line with slope -8/9 through point (-19, 16) will have the equation ...
y -16 = -8/9(x +19)
Y for x=17You want the value of y for x=17. We can find that by substituting x=17 into the above equation:
y -16 = -8/9(17 +19) = -8/9(36) = -32
Adding 16 gives the value of y:
y = 16 -32 = -16
The line passes through the points (-19, 16) and (17, -16).
a simple random sample of 40 items resulted in a sample mean of 25. the population standard deviation is 5. what is the standard error of the mean? (round your answer to two decimal places).
The standard error of the mean is approximately 0.79 (rounded to two decimal places).
Define standard error ?
The standard error is a statistical term that measures the variability of a sample mean or an estimate of a population parameter from its true value. It is the standard deviation of the sampling distribution of the mean. In simpler terms, the standard error measures how much the sample mean varies from the true population mean. A smaller standard error indicates that the sample mean is more likely to be representative of the population mean, while a larger standard error suggests that the sample mean may not be as reliable.
The formula for the standard error of the mean is:
[tex]SE = \frac{\sigma }{\sqrt{n}}[/tex]
Where σ is the population standard deviation and n is the sample size.
Substituting the given values:
[tex]SE =\frac{5}{\sqrt{40}}[/tex]
SE ≈ 0.79
Therefore, the standard error of the mean is approximately 0.79 (rounded to two decimal places).

Let p define the probability of success in a Bernoulli trial, and P define the probability Sara wants to reach "at least" and n be defined as the number of trials. Then,
= 1 - (1 - p)ⁿ ≥ P
= (1 - p)ⁿ ≤ 1 - P

Answer: Can you check the "Recently Deleted" folder? You may find this in the "My Files" app. If this does not work, and you can confirm you have no backups whatsoever, then your photos are as good as gone. This has happened to Android devices in the past (or Samsung devices mostly) where all their media would just disappear. As far as I know, all Samsung themselves say is to restart your phone to try your luck. An app crashing or some form of corrupt media may have caused your photos to go missing. There may, however, still be a small chance that the photos are there, somewhere on your phone, you just can't find them. I advise checking the storage in "Device Care" and see if the Gallery app is using much storage. If it is, I would connect it to a PC and look through the files again.
Step-by-step explanation:
what do integers added or subtracted from the function do to the graph?
The addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.
Let a quadratic function be f(x) = 2x^2.
Let c be the positive constant.
It is now necessary to determine what will happen if we add or subtract a constant to the function.
The function f(x) = 2x^2 is a parabola opening upwards.
Now, if we add the positive constant c, then the graph of the function will shift upwards by c units and nothing will change. If we subtract the positive constant c, then the graph of the function will shift downwards by c units.
Thus, the addition or subtraction of a constant to a function will change its position in the cartesian plane. Depending on the sign of the constant, it can shift upwards or downwards.

Define Algebraic Expression
The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it. In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.).
Given expression,
-2/9 x=2/5
Isolate the variable, x
x = (2 * 9) / ( 5 * -2)
x = - (9/5) or -1 4/5

The Serenity and the Mystic are sail boats. The Serenity and the Mystic start at the same point and travel away from each other in opposite directions. The Serenity travels at 16 mph and the Mystic travels at 20 mph. How far apart will they be in 2 hours?
After 2 hours Serenity and Mystic will be 72 miles apart
The speed of the Serenity = 16 mph
The time taken = 2 hours
The speed = Distance / Time
The distance = The speed × time
The total distance traveled = 16 × 2
= 32 miles
The speed of the Mystic = 20 mph
The time taken = 2 hours
The distance = The speed × time
Total distance traveled = 20 × 2
= 40 miles

k² + 2kx + x² = m² + k² - 2kx + x² ( add 2kx to both sides )
k² + 4kx + x² = m² + k² + x² ( subtract k² + x² from both sides )
4kx = m² ( divide both sides by 4k )

Initial amount = $60
Additional earnings = $7
